but does not permanently rest on it. Continually check to verify that
the LED flashes off and then back on when you pull the trigger. If you
pull the trigger and the LED goes off and stays off, you have adjusted
the screw in too far. Back it out.
4. Adjust the spring tension by turning the screw in for more tension and
out for less tension.
5. Clean up any excess loctite and let it dry for at least an hour before
using your B2K. This ensures the screws will remain in place.
B2K TUNING GUIDE
High pressure regulator adjustment:
The B2K has a totally new and innovative system. The pressurized gas is regulated
internally. The pressure regulator is externally adjustable via the screw in the side
of the high-pressure regulator. To increase the pressure use a 3/32” allen wrench
inserted into the screw and turn clockwise.
NOTE: Only slight turns are needed to accomplish changes in the pressure used to
shoot the paintball.
To decrease the pressure shown on the gauge, turn the screw counter-clockwise.
You must take a clearing shot before the change in the decreasing direction can be
registered.
A pressure gauge has been installed into the regulator body to indicate the exact
operating pressure of the marker. This gauge is extremely useful. At the factory
we set the regulator gauge to 180-200 PSI with an input pressure of 400 PSI using
Compressed air as the base propellant. Under normal circumstances these settings
will produce paintball velocities at approximately 280-300 fps. The input pressure
from your tank should be set at 350-500 PSI.
Higher input pressures will not
provide increased performance. There is a specific input side and output side of the
main input regulator. If the gauge and input sides are switched, the outcome will be
total bypassing of the main input regulator.
Low pressure regulator adjustment (Velocity adjustment):
The low pressure regulator is externally adjustable via the adjustment screw with
the slot for a wide screwdriver or even a quarter in the front of the low-pressure
regulator. The low pressure regulator is pre-set at the factory to 85-95 PSI to
operate the 4-way solenoid actuated valve. It may be necessary to re-adjust the low
pressure regulator from time to time to achieve desired velocities. Bench adjusting
the regulator can be done by pressurizing the gun, be sure the input regulator is set
properly, and then turning the adjustment screw inward (clock-wise) until you hear
a leak coming from the 4-way valve in the grip area. The 4-way valve has an over-
pressurization relief valve that will start to bleed off at approximately 125 PSI, once
you hear the leak start then back off the adjustment screw 2 turn and the leak will
stop. That will approximate the pressure to about 90 PSI. The low pressure
regulator is designed to shut down and preserve the integrity of the low pressure
system if it sees an input pressure over approximately 400 PSI coming from the
main input regulator.

This gun was designed with safety and safety standards in mind. If you attempt to
shoot paintballs higher than established safety standards, the gun will not function
properly.
NOTE 1. You may notice that if you attempt to operate the gun at
extremely high velocities, the internals will not function properly!
NOTE 2. This gun is not designed to shoot above the safety limits
established by industry standards.
Leak Related Problems
1. The B2K has a leak down the barrel. Reason: gas is leaking through or
around the valve pin seal or O ring area.
a. Can you hear the leak when the gas is removed? Yes? There is no
leak. You hear the ocean.
b. The valve seal is marred/scratched or worn out or dirt has
gotten to it. Replace it.
2. The B2K has a leak around the high pressure regulator seam. Reason:
the seal between the regulator body and the main body is bad.
a. Tighten the regulator to the body.
b. Check and/or replace the O ring.
3. The B2K has a leak around the low pressure regulator seam. Reason: the
seal between the regulator body and main body is bad or the regulator has
loosened up.
a. Tighten the regulator into the body.
b. Check and/or replace the O ring gasket. Sized -019.
4. The B2K has a leak inside the grip/battery area.
Reason: the 4-way valve is leaking.
