MAINTENANCE AND CHANGING
ANTI CHOP EYES
The Anti Chop Eye (ACE) system will prevent the DM9 from chopping paint by not allowing the
marker to fire until a ball is fully seated in front of the bolt. The eyes use a light beam across the
breech. On one side there is a transmitter, and on the opposite side a receiver. In order for the marker
to fire with the eyes turned on, the signal between the two eyes must be broken. After every shot,
before the next ball drops in the breech, the eye transmitter and receiver must see each other. If
there is a malfunction, the LED's on the board will start blinking green. This means that the receiver
and the emitter do not see each other. If this is the case, there are normally two reasons. Either there
is dirt, paint or grease blocking the beam, or the battery is so low there is not enough power to
create a strong enough light beam.
NOTE: IF THE BATTERY IS LOW, THE MARKER MAY ACT AS IF THE EYES ARE DIRTY OR NOT
FIRE AT ALL. IN THIS CASE, REPLACE THE BATTERY.
SELF CLEANING EYE FEATURE
The DM9 is equipped with a self cleaning eye feature. There is a clear polycarbonate sleeve mounted
inside the breech of the gun covering the eyes. When the bolt tip O-ring passes through the eye pipe,
it sweeps off any dirt, grease or paint that could be blocking the eyes. Normally it is enough to just
fire the DM9 to clean anything blocking the eyes. If this does not clear the blockage use a swab to
clean the inside of the breech.
For a more thorough cleaning, pull the eye pipe with the ball detents out the front of the breech. With
the eye pipe out use a swab to clean the breech. This should be enough to clean the eye system. If the
system needs further cleaning, pull out the eye carrier and eye wires through the feed neck. To prevent
damaging the eye wires, it is best to remove the frame and disconnect the eye wires from the board.
Use a soft rag and q-tips to clean off any built up paint or grease.
When re-assembling the eye guard system, work backwards from disassembly. The eye pipe is keyed
into the breech and can only go in one way.
CHANGING BALL DETENTS
The ball detent system is clipped to the outside of the eye pipe. The ball detent system needs little
or no maintenance. The detents should easily flex out of the way with little force, such as a paintball
moving past. If you are experiencing
double feeding or chopping, check
the condition of your ball detents
with your finger to make sure they
are not broken, stuck in the up or
down position, and that they move
in and out of the breech freely. If
excessive broken paint or dirt has
jammed your ball detents, remove
the eye pipe/detent system from the
front of the DM9 and unclip the
detents for a thorough cleaning.
Reinstall the detents, and eye pipe
after you have sufficiently cleaned
the detents and breech.
Be careful not to over-flex the
detents when handling them.
Excessive flexing could break or
damage the detents.
NOTE: TAKE CARE WHEN REPLACING THE EYE PIPE. BE CAREFUL THAT THE DETENT
CLIP IS FULLY SEATED ONTO THE EYE PIPE
