Introduction



This guide is organized by symptoms, followed by a progression ofprobable causes. The steps to determine a problem are:

1. Consult the Major Categories section of the Trouble Shooting Outline on page 2.
2. After determining which Category best describes the problem, refer to it again in the Sub-Major Categories of the samepage.
3. Determine which sub-paragraph best describes the problem.
4. Refer to subject paragraph in the Trouble Shooting Guide.

This guide will help determine "what" is wrong, not necessarily"how" to repair the problem. This is why the Owner's Manual (OM)is referred to heavily throughout this guide. There are numerousreferences to disassembly steps (DS). This will allow you accessto the problem area with the least amount of labor. These stepsare listed as "[DS: #]." The numbers within the brackets refer tothe steps themselves. Ensure not to confuse the assembly steps(AS) of the OM with those of the disassembly.

Descriptions referring to left and right are from the perspectiveof you looking at the gun with its barrel to your left and thepistol grip pointing down, similar to the position of the Vectoron pages 9 and 10 of the OM. Check the glossary of this guide forassistance in locating a particular part.

If your Vector requires factory repair and is under warranty,please ensure it is registered. If you are requesting warrantycovered parts, return the broken parts and provide your serialnumber. If your Vector is not registered, accompany the repairwith a completed warranty card or a copy of the sales receipt. Wewill register it.

Your suggestions and comments are strongly desired. The collectiveexperiences of all owners place you in a position to be exposed topredicaments we have not imagined or experienced. Please provideany feedback you may have regarding the contents of this guide orproblems not listed.

Trouble Shooting Guide


1. Firing


1.1 Cycles but does not fire.

DS: 1, 5

1.11 Cylinder mount screw loose or missing.

DS: 8

1.12 Sear roller missing.

DS: 6, 7, 9-19

1.13 Hammer sear.
1.131 Sear pin damage.
1.132 Sear latch face worn.
1.133 The sear has caused wear on the hammer. This
causes the front half of the sear to be positionedhigher (inward to the hammer). It is unable torotate down (CCW) far enough to latch to the boltcarrier.
1.14 The end of the main spring has broken off and is
preventing the hammer from latching.
1.141 Remove the broken end. Because the springs are
grounded flat at the ends for perpendicular ends,some are thinner than others and will break away apartial coil. This does not diminish theperformance of the spring. Instead, it would bepreferable to continue to use this spring since itwill not repeat this malfunction. Install thespring with the broken facing front and the flushend to the rear to bear upon the hammer. If it isreplaced, designate whether your Vector isback-bottle or external regulator (Thruster)configured. There are different springs for each.
1.142 Rotate the bolt carrier while viewing it fromthe rear. Look for any eccentricity in rotationof its extension tube. If it is off-center, thebolt carrier must be replaced. (SFR)
1.2 Fires gas but not a ball.

DS: 1

1.21 Drive slider pin missing.
1.22 Ball jam in feeder, feeder tube, or barrel feed tube.Check for paint, shell or FOD in these areas.

1.3 Ball breakage.

DS: 1

1.31 Breaking in the breech.
1.311 Drive slider pin is missing.
1.312 The ball is too large or out of round to be
loaded.
1.32 Breaking in the barrel.
1.321 Debris within barrel.
1.322 Attributable to the paintball (Too large, too
small, out of round, thin shelled, soft spots,dimpled, flat spots, etc).

2. Action


Note: References to the term "cycle" refers to the observable motion of the bolt (slider pin installed.)


2.1 The bolt oscillates (vibrates, buzzes, chatters) inthe forward position when the trigger is pulled. Thedisconnector guide pin is of the wrong diameter ormissing. (SFR)

2.2 Slow motion cycle.

DS: 1, 2

2.21 Check for ease of motion by manually moving slider. If resistent to movement, then go to followingsub-para graphs.
2.211 Bent slider.
2.212 Slider guide grooves are obstructed.
DS: 5
2.213 Upper foregrip screws are too tight.
2.22 Kinked plastic (low pressure) lines. The line from the regulator to the four-way valve is purposely cut longand looped. This loop should be in an upward position.If position down, then the floor of the foregrip may press againstit and restrict pressure in the line.
2.23 Four-way valve end plate cracked or loose.
2.24 Four-way valve screws are loose. AS: 15, 17
2.25 Mis-alignment between four-way valve pin and trigger valve arm.
DS: 8, 9
Connect gas to the gun and operate the valve pin byhand. If action is normal then the problem was alignment. Perform AS 15, 16, 17 and test fire.

DS: 6, 7, 10-13, 15-19

2.26 Receiver bore requires cleaning and lubrication.

2.3 Partial cycle (motion from rear to front). Gunmay fire once and no more after a trigger pull or gascharge.

DS 1, 5, 8

2.31 Trigger sear spring missing.
2.32 Disconnector guide pin missing (SFR)*.
2.33 Disconnector plunger or plunger spring missing.
2.34 Trigger spring missing.
2.35 Interference to the motion of the piston within the
regulator (Carty's Syndrome). Remove the regulatorbonnet. Inspect interior for FOD. (It is known of wherea piece of an adapter body o-ring had traveled from theadapter into the regulator).
2.36 The bolt carrier is mis-positioned on the pneumatic
cylinder piston arm. The trigger valve arm on the resetportion of the action cycle pushes the 4-way valve pinto the front by rotating clockwise. This motion isdelivered by the carrier as it passes over the top ofthe valve arm. The carrier must be in a precise positionon the cylinder arm to properly make contact with valvearm. Input pressure to the gun and operate. See if thevalve arm is being reset. (SFR)

2.4 No cycle.

If the bolt is in the forward position also refer toparagraph 2.3.

DS: 1, 2

2.41 Check for ease of motion by manually moving slider. If
resistent to movement, then go to followingsub-paragraphs.
2.411 Bent slider.
2.412 Slider guide grooves are obstructed.
DS: 5
2.413 Upper foregrip screws are too tight.
2.42 Kinked plastic (low pressure) lines. The line from the
regulator to the four-way valve is cut long andpurposely looped. This loop should be positioned in anupward position. If position down, then the floor of theforegrip may press against it and restrict pressure inthe line.
2.43 Check the four-way valve end plate for loosness are
damage. Tighten if loose. Replace if damaged.


DS: 8

2.44 Trigger sear not rotating clockwise enough to disen
gage from the trigger valve arm (Hunt's Syndrome). Applypressure to the gun and operate. Observe the motion, ifany, of the sear.

DS: 9, 10

2.45 Four-way pin motion is hampered. Loosen pin guide
enough to slightly reposition, tighten it back, and testmotion of pin. Repeat this procedure several times ifnecessary. If pin motion is still impeded, then removefour-way valve pin guide, pin bushing, and pin. Inspectfor FOD and clean.
2.46 Place safety switch in the fire position. Pull the
trigger and look for clockwise motion on the triggersear. SFR if the sear does not move.

DS: 6, 7, 11-19

2.47 The receiver bore, bolt carrier, or hammer requires
cleaning.
2.48 The main spring has a broken end which may have jammed
the action.
2.481 Remove the broken end. Because the springs are
grounded flat at the ends for perpendicular ends,some are thinner than others and will break away apartial coil. This does not diminish theperformance of the spring. Instead, it would bepreferable to continue to use this spring since itwill not repeat this malfunction. Install thespring with the broken end facing front and theflush end to the rear to bear upon the hammer. Ifit is replaced, designate whether your Vector isback-bottle or external regulator (Thruster)configured. There are different springs for each.
2.482 Rotate the bolt carrier while viewing it from the
rear. Look for any eccentricity in rotation of itsextension tube. If it is off-center, the boltcarrier must be replace. (SFR)
2.49 The hammer sear pin has broken.


2.5 Jams.

2.51 Paintballs are too large or out of round.
2.52 Debris is interfering with the drop or feed of the
ball.
2.53 Extreme rapid shooting. Ball drop rate is insufficient.
2.531 Use a feeder with an agitator.
2.532 Use an elbow with a larger bend diameter.
2.533 Use a zero degree (top, center) feed barrel a
opposed to the 45 degree feed. This allows a high ball drop rate. Available at Air Power.
2.54 Barrel mount extension tube projects into ball drop
area: Inspect the breech by looking through the barrel feed port. The barrel mount tube should not extend into the area where the ball drops. It may be flush in line with the rear wall of the feed port. Ensure your view is in-line with the wall of the port.

3 Trigger


[DS: 1, 5, 8

3.1 Stiff or immovable.
3.11 Disconnector position is too high on the trigger sear.
3.12 Side cover screws are too tight.
3.13 Corrosion.

3.2 Trigger remains in its rear most position.
Missing or broken trigger spring.

4 Velocity


4.1 Low velocity.

4.11 CO2 source is limited or restricted.
4.111 Low bottle pressure.
4.1111 Tank is nearly empty.
4.1112 Ambient temperatures has the pressure.
4.1113 Intensive shooting has lowered tank temper
atures which have in turn lowered thepressure.
4.1114 A heat shield is in place, such as a neo
preme cover, blocking ambient air fromwarming the tank.

4.112 Faulty bottle valve. Submit to your local gun-
smith for repair.
4.1121 Retraction of the pin is hindered by
debris, corrosion, or the pin seal has wornor shifted.
4.1122 Height of exposed pin is too low. Sits well
below the flat surface of the end of thevalve.

DS: 4a, 4b

4.12 Seat valve hole is not aligned with gas exhausthole of the adapter.

ABDS: 1, 2, 3

4.13 Cup problem.
4.131 Plastic sealing element worn.
Inspect condition of the seal. If deeply orirregu larly grooved, replace the sealing element orboth the element and cup.
4.132 Cup is loose or mis-positioned on valve shaft.
Note: When a cup becomes loose it is possible. for the shaft to be driven back into the cup. Hidden
damage may be present on the threads. The flange of the shaft should be flush against the face of thecup.
4.14 Valve shaft damaged.
4.15 Return spring.
Incorrect spring. Spring with internal velocity control has 5.5 coils, whereas the one used with externalregula tors such as Thrusters has 8.5 coils.
DS: 1, 5-13, 15-19

4.16 Hammer motion has slowed.
4.161 Hammer cavity has build up of old oil.
4.162 Too heavy of a lubricant being used.
4.163 Little if any lubricant is present.
4.164 Incorrect main spring.
Spring with internal velocity control has 10.8coils and is 1 3/4 ins (47mm) long. Whereas, theone used with external regulators such as the Thruster has 10.7coils and is 2 ins (52mm) long.
4.165 Hammer sear pin is out of position and dragging on interior wall of the receiver.
4.17 External regulator (Thruster) in use.
The seal may be worn on the regulator. If a pressure
gauge is available check for controllable output which remains steady after each setting. A bad seal would show a slow rise after each setting or not allow control of thepressure output to change. (SFR)
4.18 Internal velocity control in use (back-bottleconfig uration): The alignment of velocity piston to theadjust ing screw is incorrect. The rear edge of the pistonhas to areas which are cut deeper than the rest of the rearsurface. The proper alignment requires the adjustment
screw to make contact with the piston in any one ofthese cut-outs.

4.2 High velocity.

4.21 Liquid CO2 entering gun.
4.211 Bottle directly connected to adapter body and
Vector pointed in a less than 90 degree angle.
4.212 Siphon bottle in use.
4.213 Back bottle set-up in a horizontal angle such as aplayer in a prone position.
4.214 Rapid shooting has cooled the CO2 system to the point where the liquid can not expand to gas.
4.215 Climatic temperatures are of such that CO2 willnot expand into gas from a liquid state.
ABDS: 1, 2, 3

4.22 Loose cup.
Inspect the cup's position in relation to the valve
shaft. Look for exposed threads on the shaft. The cup
should be flush against the flared shoulder of theshaft. If required, reset the cup on the shaft asinstructed by [MS: Cup]. Thread damage is possible. When acup comes off within an internal velocity adjustment setup it ispossible for it to be jammed back onto the shaft threads.
4.23 Internal velocity control in use - back-bottle
configuration.
4.231 Velocity adjustment screw missing.
4.232 Velocity piston missing.
4.24 Springs.
The main or return spring could be of the wrong type
regarding the set-up of the Vector.
4.241 Return spring.
Spring with internal velocity control has 5.5coils. Whereas, the one used with an externalregulator
such as Thrusters has 8.5 coils.

DS: 1, 5-13

4.242 Main spring.
Spring with internal velocity control has 10.8coils and is 1 3/4 ins (47mm) long. Whereas, theone used with external regulators such as the Thruster has 10.7coils and is 2 ins (52mm) long.
4.25 External regulator (Thruster) in use.
The seal may be worn on the regulator. If a pressure
gauge is available check for controllable output which remains steady after each setting. A bad seal would show a slow rise after each setting or not allow control of thepressure output to change. (SFR)

4.3 Erratic velocity

4.31 Springs. See paragraph 4.24.
4.32 Valve cup. See paragraph 4.13.
4.33 External regulator (Thruster) in use. See paragraph 4.25.

4.4 Unalterable velocity

4.41 External regulator (Thruster) in use. See paragraph 4.25.
4.42 Velocity piston. See paragraph 4.23.

4.5 Higher than normal pressure required from anexternal
regulator to achieve acceptable velocities.

See paragraph 4.1 Low Velocity.

5 Gas Leak

5.1 Adapter

5.11 Leaks from the rear where CO2 bottle valve or line fits into adapter.
5.111 Check o-ring on bottle valve, stock connector or line connector. If damaged, check both female and male threads for burrs, disfigurement, or debris
before installing a replacement.
5.112 Top edge of bottle valve, stock connector, or line connector may be damaged. Submit any damaged bottle valve to a competent paintball gun-smith for
repair.
5.113 The pin of the bottle valve is positioned too high above the surface of the valve. Submit bottle to a competent paintball gun-smith for repair.
5.12 Leaks from the seam of the adapter and receiver or from the base of the adapter pin. Check the rear adaptero- ring for damage. [DS: 4a, 4b]. Before installing a
replacement o-ring, inspect the left wall of receiver
cavity. Look for burring around the high pressure block screw holes or the extension of those screws into the
cavity. Such extension is caused by over-torquing.

5.2 Barrel mount-bolt-barrel area.

5.21 Forcefully leaks through the barrel when charging the system. Pull the trigger a few times. If nothing else is wrong, the leak will stop. Refer to the charge upprocedures in this guide.
5.22 Low pressure.
5.221 Low quantity of gas in source tank.
5.222 Low temperature (CO2 as the propellent).
5.2221 Low ambient temperature.
5.2222 The temperature of the tank has been reduced by a great deal of rapid shooting.
5.2223 An external regulator is either set too low or not operating properly. See paragraph 4.17.

DS: 4a, 4b

5.23 Valve shaft assembly.
5.231 Valve shaft motion.
Check for uneven motion on the short back and forth action of the valve shaft. If it moves freely go tonext paragraph. If not, then lubricate and check again. If stillresistive, perform [ABDS 1, 2]. Check for FOD and corro- sion onthe shaft and its course within the seat.
ABDS: 1
5.232 Damaged or missing rear valve seat o-ring.
ABDS: 2
5.233 Seat lip may be nicked or chipped.
5.234 Loose or mis-positioned cup.
Inspect the cup's position in relation to the valve shaft. Look for exposed threads on the shaft. Thecup should be flush against the flared shoulder of the shaft. Ifrequired, reset the cup on the shaft as instructed in [MS: Cup].It is possible, with an internal velocity adjustment set-up, thatthe cup may have came off and then jammed back onto the shaft,damaging threads in the process.
5.235 Cup seal (the plastic inlay within the cup.)
5.2351 Cold temperatures can cause a poor seal. Not only does the plastic become harder but thepressure of the CO2 drops and exerts less force on the cup alongthe seal. In most cases firing a few shots will enable a seal. Ifnot, try some gun oil on the seal.
5.2352 Worn seal. Inspect condition of the seal. If deeply or irregularly grooved, replace the sealingelement or both the element and cup. [MS: Cup].
5.2353 FOD may become imbedded on the seal. Because it can be very small, a good light and magnifyingglass would be useful. Carefully try to remove the FOD with aslender pick or pointed tweezers without damaging the surface ofthe seal.
5.2354 Hard seals: Some elements are too hard at first to allow a proper seal by the seat Important: Check for FOD (see paragraph above.) If the resultsare negative, then fire gun repeatedly to work the seat into theplastic to form a seal. To do this without prior checking for FODon the seal runs the risk of irreparably fixing the FOD deeperinto the seal.



5.3 Trigger area.

(Leaks from the bottom of the receiver in the area of the trigger.)


DS: 1, 2, 4a, 4b

5.31 Forward adapter o-ring damaged.
Before installing a replacement o-ring, inspect the left wall of receiver cavity. Look for burring around thehigh pressure block screw holes or the extension of thosescrews into the cavity. Extension such as this is caused byover-torquing.

ABDS: 1, 2

5.32 Seat o-rings damaged.

5.4 Left exterior side of the receiver.

DS: 1, 5-7, 14

5.41 Leaks from around the edges of the high pressure line block. [DS: 1,5,6,7]. Replace o-ring located behind the high pressure block.
5.42 Leaks from the junction of the high pressure line and line block. (SFR). Return either the gun or the high pressure line assembly.

5.5 Foregrip area.

DS: 1, 5

5.51 Leaking stops when the foregrip is removed. Contact by the interior bottom of the foregrip against a plastic line is the initial cause of the leak.
5.511 Gently press upward the brass low pressure outlet lead at the bottom of the regulator. Look for leakage where it is joined. The sealant at the base of the leadcan fail. (SFR)
5.512 Check the ends of all plastic lines. Look for splitting or a shallow fit.
5.52 Leaks from where the high pressure line enters the line fitting at the rear of the regulator.
5.521 Check the fitting for looseness. Hand tighten if so. If access is difficult:





DS: 6, 7, 14

5.523 If leaking continues after tightening thefitting, check for FOD underneath it.
5.5231 Unscrew the fitting and remove. Remove from
the fitting three o-rings and two backingrings (spacers).
5.5232 Inspect for and remove any FOD from the
interior of fitting, o-rings, spacers, andfemale threads of the regulator.
5.53 Leaks from where the low pressure outlet lead isjoined to the regulator. (SFR)
5.54 Low pressure plastic line not connected to brass leads.
5.541 Plastic line may have had a shallow attachment to
a brass lead. Reattach and work the line up andover a generous portion of the lead.
5.542 Not enough of the line was placed beyond theend of the lead.
5.543 The line has split ends or has been stretched to
a larger diameter to where it no longer fitstightly.
5.544 The line continuously separates from a lead.
5.5441 Remove forward housing (bonnet) from the
regulator by unscrewing it.
5.5442 Remove regulator spring and pistonfrom the bonnet. The piston should come outwith ease.
a. The piston is difficult to remove. (SFR).
(Seven Vectors were made with oversizepistons causing too much pressure to exitthe regulator and the lines to come off.This problem would be apparent when thegun is new.
b. Check for and remove debris on the piston
shaft seal (white plastic plug). Checkseal's position by pushing it into theshaft. If there is movement of the sealthen replace it.
c. Check the condition of the two shaft o-
rings and replace if necessary.
5.55 Leaks from within the regulator [rare event]. Unscrew
the bonnet from the regulator. Remove the piston andcheck the condition of its two o-rings. Replace ifnecessary.

5.56 Four way valve. Note: The four-way valve isdesigned to vent gas from the forward right aperture ontop of the manifold. Normally, this is a very low sound.The rate of this venting is approximately an eighth toquarter ounce per hour. In some cases the sound mayvary or increase. CO2 liquid or a change of pressurewithin the system may be the cause. A higher ventingrate may indicate a 4-way valve malfunction (SFR).Evidence of this would be lower shots available pertank-full or immoderate weight lost. First, determinethat there is no other source of leaks. Fill the tankand attach to the system and weight it. Set aside anweigh it again. Remember the maximum allowable ventingrate is 1/4 ounce per hour.

5.561 Check the front, black plastic end cap for
either cracks or looseness (both rare.) A crackedcap should be replaced. If loose, tighten withcaution. Over tightening may cause a corner of thecap to crack.
5.562 Leaks from between the manifold (rectangular
silver plate on top) and the valve. (SFR)

6. Safety Switch


DS: 5, 7, 9

6.1 Too difficult to operate.
The safety tension screw may be exerting too much tensionon the switch. It is located on the lower front of thereceiver body. The four-way valve when installed concealsit. Vary the position of the screw to alter the tension onthe switch.

6.2 Too easy to operate.
6.21 The safety tension screw may be exerting too little
tension on the switch. It is located on the lower frontof the receiver body. The four-way valve when installedconceals it. Vary the position of the screw to alter thetension on the switch.
6.22 The safety tension spring or ball bearing may be
missing. Remove the tension screw and check for their presence.

7. Fitting of parts.



7.1 Barrel (loose or tight).
The regulator mount has a hole at top center which receives the pin of the barrel lug. By loosening the screw on thenon- split side of the mount and then placing the wrench intothe head of the other screw you may use the wrench as alever to turn the regulator mount either CW or CCW. Test fit thebarrel to determine if the adjustment has been enough.
7.2 Side cover.
If the side cover is difficult to position onto the receiver block, loosen the screw forward of the trigger guard. Position the side cover and tighten the trigger gaurd back into place.
Appendix 1

Maintenance Hints

Cup
Unscrew the cup from the shaft. If the cup will not turn,breakdown the adhesion of the Loc-tite by applying a flame, suchas from a cigarette lighter to the rear of the cup. Do this untilit begins to smoke. Remove the cup. Clean and apply a small amountof Loc-Tite retaining compound 680 to the threads of the shaft andscrew on another cup and seal using firm torque. Wipe away anyexcess compound, particularly on the surface of the seal. Allow toset for three hours before exposing the Loc-Tite to CO2temperatures. Seal alone can be replaced but must be press fittedinto the cup. A vice with smooth wall inserts placed within thejaws may suffice for a press.

Trouble Shooting Under Power
The Vector can be operated while the side cover and theforegrip are removed. The action of the hammer can be observed bythe motion of the hammer sear. Of course, the pieces of thetrigger assembly can be easily viewed along with the motion of thefour-way valve pin. To isolate the trigger assembly from any test,remove the two four-way valve screws and allow the valve to hangloosely by its plastic hoses. The valve can be operated by hand bypressing the valve pin in and allowing its spring to push it out.


VR3500 Regulator Installation and Adjustment

The output pressure adjustment for the VR3500 is locatedunderneath the hexed shaped cap which is called the tournamentcap. The altering of the output pressure will affect the velocityof the marker. It is not necessary for the regulator to bepositioned into the adapter body where it is tight or comes to astop. Rather, turn the regulator in until it stops and then backout until the input line is in a non-binding position and thegauge is readable from the right side.
The Vector's ideal pressure input is normally between 450 to600 psi. For setting the velocity for the first time, start withthe adjustment screw at its most outward position. Fairly lowpressure will be indicated, usually 400 psi or less. In smallincrements of 1/4 to 1/2 clockwise turns adjust the setting. Oncepressure reached 450 psi began taking samples of ball speed over achronograph. Discount the first shot after an adjustment. Thesecond will be more reflective of previous adjustment. Continuethis until you have reached the desired velocity.
Installation of Internal Velocity Adjustment to the Vector
The following components are required to convert the Vector forinternal velocity adjustment:

- Velocity piston
- Screw 13, velocity adjustment
- Spring 08, main
- Spring 12A, return
- 5/64 hex wrench

Perform the following disassembly steps as described in theVector Owner's Manual:

Steps 1 through 13 of "General Maintenance and Cleaning Disassembly"
Step 1 and 3 of "Adapter Body Disassembly"

The rear of the velocity piston has a flat ("closed") surfacewith two ports on the rim. The "open" end of this cup shapedcomponent faces toward the front of the Vector. Insert the pistoninto the adapter body. Align the ports with the two holes at theback of the adapter. Install the adjustment screw into the tappedhole on the right. The screw is to make contact with the piston ata port. Low velocity will be the results if the screw contacts thepiston any where else. Install the valve shaft into the seat andplace the return spring on the back of the cup. Insert into theadapter and screw the seat into place.
Replace the main spring, pictured on page six in picturethirteen.
For adjustment of velocity refer to the instructions on page 16of the Vector Owner's Manual.
Push Button Safety Installation For The Vector

Material Required:
Pin, spring, and "push-button" safety (PBS) switch.

1. DS1 Remove barrel
2. DS5 Remove foregrip
3. DS8 Remove side cover
4. DS9 Remove the two four-way valve (FWV) screws
5. DS10 Remove FWV away from the receiver housing.
6. The FWV fits into a recessed area of the receiver housing. On the rear half wall of this area is a set screw. Remove it.
7. Underneath the screw is a spring and ball bearing. Removethem. Do not use this spring with the PBS.
8. Remove the safety switch from the receiver.
9. Install PBS into its receptacle. Note the groove.
10. Install the pin into the hole from which you removed thescrew, spring, and bearing.
11. Align the pin and PBS so that the pin will engage with the groove.
12. Install the FWV. It will be the back-stop for the pin.
13. On the interior end of the PBS is a hole. Place the spring which accompanied the PBS into it. The side cover will act as its back-stop.
14. Reassemble Vector.
15. Caution: Whenever the side cover is off, be aware that the PBS spring can slip out of the switch if the housing is held up or turned over. Also be aware of the retention pin whenever the FWV is removed.


Adapter Body O-rings

Removal of the adapter body should be considered only by a maintenance requirement. The o-rings are susceptible to damage ifthe adapter body is removed soon after gas has been exposed to itso-rings. These o-rings will absorb the gas and increase in theirsize. If possible, reframe from removing the adapter from thereceiver block without first allowing fifteen to twenty minutes topass. This should be sufficient time to allow for the o-rings todissipate the gas. If it is necessary to remove the adapter beforeallowing this much time to elapse, do so gently. Carefully, pullthe body out while slowly rotating it back forth in forty-fivedegree arcs or less. The most critical moments in the life ofthese rings is when inserting the adapter back into the receiver.Either replace the swollen rings and set them aside to be usedlater or lubricate with a small amount of oil. In either case, begentle the insertion of the adapter.

Operating Description

The Vector can be operated with the side cover and foregripremoved. This will assist in an understanding of the operation ofthe system.

Primed Conditions

Gas pressure in the adapter body forces the front of the cupagainst the seat to create a seal. This pressure is also directedforward by the high pressure line to the regulator and reduced to100 psi. Exiting the regulator from the bottom rear, the pressureis passed on to the center lead of the manifold. Its two outeroutlet leads presents either negative or positive pressure ateither end of the pneumatic cylinder.

When pressure is present the gun is ready to cycle. A paintball isin the breech and held in place by the detente spring. Thisensures that the next ball stacked above does not have a presencewithin the core of the breech. The cylinder piston is fullyextended out to the rear, placing the bolt and bolt carrier attheir most rearward position. The hammer sear is latched to thecarrier. The main spring is compressed between the carrier and thehammer. The trigger sear is latched to the trigger valve armpreventing it from moving CCW.

Firing Actions

When the trigger is pulled it rotates CCW causing the disconnectorto push against the bottom of the trigger sear. As the triggersear rotates CW it presents a different posture to thedisconnector. The disconnector then slips past the sear and comesto a stop against the disconnector guide pin. The CW motion of thesear causes it to pull away from the top of the valve arm. The armwill rotate CCW because the four way valve pin spring within thevalve is pushing the pin to the rear against the arm.

This rearward position (extended) of the four-way valve pin causesa reversal of pressure at each outlet of the manifold and in turnat each end of the pneumatic cylinder. The cylinder piston movesforward pulling the bolt carrier, slider pin, compressed mainspring, hammer and hammer sear. The drive pin pulls the slider andbolt forward which chambers the ball into the bore. As the rear ofthe hammer sear drags over the hammer sear roller, the searrotates CCW. This releases its hold on the carrier allowing themain spring to thrust the freed hammer to the rear where itstrikes the valve shaft.



When the valve shaft is struck it moves to the rear pushing thecup away from its contact with the seat. This action opens thevalve. Gas flows into the rear of the seat and passes upwards intothe barrel mount. From there it flows through the mount'sextension tube and through the hollowed bolt to impact against thechambered paintball.

Reset Actions

The pressure within the adapter body again forces the cup againstthe seat shutting off the flow of gas used to propel the ball.

At the forward end of the bolt carrier's stroke, it makes contactwith the top of the valve arm and causes it to rotate CW. Thismotion moves the latching tab of the arm in line with the latchingrecess of the trigger sear. The sear, no longer blocked by thearm, is pushed CCW by the sear spring causing it to latch to thearm. The trigger spring resets the disconnector and trigger.

The valve arm also pushes forward the valve pin causing a reversalof pressure at each of the manifolds outputs. This causes thecylinder piston to reverse direction to the rear pushing the boltcarrier, slider pin, slider, bolt, and main spring. The mainspring pushes against the hammer against the valve shaft. Thepressure within the adapter body prevents the shaft from beingpushed rearward thus stopping the hammer. Motion of the boltcarrier continues to the rear now causing the main spring tocompress. The extension tube on the rear of the carrier acts aguide for the spring compression to prevent buckling which wouldbe unwanted resistance. The hollow within the hammer allows it toaccommodate the tube and be positioned closely to the carrier. Thehammer sear, at its full CW by the pushing of the sear spring,makes contact with the inclined face of the carrier's latchingshoulder. This contact and continued motion of the carrier impartsa CCW motion on the sear until it reaches the peak of theshoulder. Here the shoulder drops away allowing the sear spring tomove the sear CW and become latched to the carrier.

The next ball to be chambered is sitting on top of the bolt. Whenthe bolt moves to the rear it passes clear of the ball which dropsinto the breech. The detent spring prevents the ball from rollingforward which would allow another ball to enter either partiallyor fully into the breech.
