ANTI CHOP EYES/ BALL DETENTS
MAINTENANCE AND CHANGING
ANTI CHOP EYES
The Anti Chop Eye (ACE) system will prevent the M8 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 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 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 M8 is equipped with a self cleaning eye feature. There is a clear polycarbonate piece mounted
inside the breech of the gun covering the eyes. When the bolt tip O-ring passes through the
acrylic piece, it sweeps off any dirt, grease or paint that could be blocking the eyes. Normally it is
enough to just fire the M8 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, remove the eye
covers, you will need a
1
⁄16” Allen wrench. Simply insert the Allen wrench into the hole in the eye
cover to access the retaining screw. As you back the screw out, the plate will be pushed up.
Next pull out the eye receiver/emitter from the eye seal (avoid pulling the wires) remove the ball
detents and finally pull the eye guard out the front of the breech. Avoid scratching eye guard.
Use a soft rag and q-tips to clean off any built up paint or grease. When assembling the eye guard
system, work backwards from disassemble. The Eye guard is keyed into the breech and can only
go in one way. Make sure the Ball Detent holes are lined up.
CHANGING BALL DETENTS
The ball detent system is also located under the eye covers. The ball detent system needs little or no
maintenance. There is a spring behind each detent, which holds the detent forward. This spring
pressure should be easily overcome
with very 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 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 plates (being careful not to
lose the detent springs) and pull the
detents out for a thorough cleaning.
Reinstall the detents, springs and
eye covers after you have
sufficiently cleaned the detents and
breech.
NOTE: TAKE CARE WHEN REPLACING
THE EYE COVERS. OVER-TIGHTENING THE
RETAINING SCREW COULD RESULT IN
STRIPPING THE THREADS.
