Trigger Adjustment
ADJUSTING YOUR TRIGGER
The trigger’s forward travel and over travel are fully adjustable so that the user can fine-tune the trigger to his or her exact liking.
• Remove the grip frame from the body of the DM4.
• As you pull the frame away from the body, take care as to not damage the wires
running between the two parts. Be careful not to lose the trigger spring.
• The two adjustment screws are located at the top of the trigger in the grip frame.
[see figure 1]
• Use a 5/64 Allen wrench to make the desired adjustments.
• The screw to the front of the trigger controls the forward travel. Screwing it in will
shorten the trigger’s length of pull.
Note: If this screw is adjusted too far, the switch will be held down at all times and the marker will not fire.
• The screw to the rear of the trigger controls the over travel. By turning this screw you
can adjust how far the trigger will travel after it reaches the firing point.
Note: If this screw is adjusted too far, the trigger will not be allowed to travel far enough to depress
the switch and fire the marker.
• When the desired trigger pull has been achieved, reattach the
frame to the body.
• Take care that the spring is seated properly. Using the trigger
without a spring is not recommended and will cause the micro
switch to fail much sooner than when a spring used.
• Be sure that all wires are laid properly in
their appropriate cavities.
NOTE: Be sure that the frame and trigger assembly are kept
clean. If there is excess dirt or paint build up around the trigger
the trigger will no longer move freely. In addition paint and dirt
can cause the micro switch to not function properly or fail.
CAUTION: BE SURE YOU DO NOT PINCH
THE WIRES BETWEEN THE FRAME AND
BODY WHEN REATTACHING
THE FRAME TO THE BODY.

• Be sure the trigger is not adjusted to the
point where it is too sensitive and may
cause accidental discharge of the marker.
• Removing the trigger spring will cause
pre-mature wear on the micro switch,
resulting in failure.
• Be sure you do not pinch the wires
between the frame and body when
reattaching the frame to the body.
