Proper storage of the marker

When you are finished using the BT-4™ it is important that you prepare the marker for
storage. This will not only serve to increase the life of the marker, but will assure opti-
mum performance on your next outing.

Unloading 

1. Put on an eye protective device designed specifically for paintball and make sure that anyone

within range of the BT-4™ does the same.

2. Make sure the barrel blocking device is properly installed and the marker safety is set to “safe”.
3. Loosen the loader clamping screw.
4. While holding the paintball hopper in place, invert the marker so that the hopper is below the

BT-4™.

5. Remove the hopper and all paintballs.
6. While pointing the BT-4™ in a safe direction, remove the barrel blocking device and set the

safety to “fire”.

7. Keep the BT-4™ pointed in a safe direction and pull the trigger several times to insure there

are no balls remaining in the chamber or the barrel.

8. Properly re-install the barrel blocking device and set the safety on “safe”.

Removing The Air Supply

1. Make sure the barrel blocking device is properly installed and the BT-4™ safety is set to “safe”.
2. Point the BT-4™ in a safe direction and turn the cylinder counter clockwise about 3/4 of a turn.

This allows the cylinder valve to close without damaging the cylinder O-ring.

3. While pointing the BT-4™ in a safe direction, disengage the safety (set to “fire”).
4. Keeping the BT-4™ pointed in a safe direction, pull the trigger until the remaining CO2 or air is

expelled and it fails to re-cock. 

5. Unscrew the cylinder from the BT-4™.
6. The marker is now ready to be cleaned or put away for future use.  

Cleaning the marker

Once the BT-4™ is unloaded and the air cylinder is removed, you can use a damp cloth to wipe
off paint, oil, dirt and debris. You can also use warm water to rinse the marker clean. Once your
marker is clean and dry you can re-oil using a light, premium marker oil. (Note: Petroleum based
and aerosol products can damage your markers o-rings. 

DO NOT USE ANY PETROLEUM

BASED OR AEROSOL PRODUCTS ON YOUR MARKER.

) To access the rear bolt and linkage

arm you must remove the left receiver half. (See marker disassembly section.)

Always store the marker in a secure location when not in use so as
to prevent access by unauthorized persons. 

Disassembly and field stripping

(MARKER MUST BE UNLOADED, DEGASSED AND UNCOCKED BEFORE ANY DISAS-

SEMBLY. FOLLOW UNLOADING AND REMOVING AIR SUPPLY STEPS.)

Remove The Barrel

Turn the barrel counter clockwise to remove from the marker.

Vertical Front Foregrip Removal/Relocation 

The vertical foregrip may be removed or may be relocated along the lower
picatinny rail as needed. To remove or adjust location:

Note:

If relocating make sure marker is pointed in a safe direction, barrel blocking

device is installed and safety is set to safe.
.
1. Turn vertical foregrip retainer counter clockwise to allow retention pin to drop.  A coin

may be used to assist in turning the vertical foregrip retainer.

2. Slide foregrip to preferred location or remove if so desired.
3. Reverse process to replace foregrip.  

Note that the retention pin must line up in a gap on the picatinny rail.
