• Put on an eye protective device
designed specifically for paintball and
make sure that anyone within range of
the Marker does the same.
• Turn the feed adapter plug to the "A"
position and lock the feed tube
plunger in the back position. (Fig. 3. 1 0)
• Using a 10 round tube or manually
inserting the paintballs fill the feed
tube with quality .68 caliber paint-
balls.
• Turn the feed adapter plug to the "B" position to feed paintballs into the
Marker or to position "C" to lock them within the feed tube.
• Release the feed tube plunger so it tensions the paintballs.
• Your Marker is now loaded.

• Aim the Marker at the target.
• Place your finger on the trigger.
• Pull the trigger with a smooth squeezing motion.

5. Velocity Adjustment

Always check the velocity of the Marker prior to playing paintball.
Different playing fields may have different maximum velocity limits. At no
time should you shoot at velocities above 300 feet-per-second (91.44
meters-per-second).
• Put on an eye protective device designed specifically for paintball and
make sure that anyone within range of the BT Marker does the same.
• While pointing the Marker in a safe direction, remove the barrel-block-
ing device.
• Point the BT Marker over a chronograph that will measure the velocity
of the paintballs discharged by the marker.
• Set the Marker to "Fire" mode.
• Pull the trigger and check the reading on the chronograph.
• Locate the Velocity Adjuster screw on the back of the marker.
• Using a 3/16" Allen wrench, turn the screw inward or clockwise to increase
the velocity, and outward or coun-
terclockwise to lower the velocity of
the paintballs discharged from the
Marker (Fig. 5. 1 ).
• In some cases a different ham-
mer spring may be needed to
achieve the desired velocity.
