M8 BOARD
BATTERY
ON/OFF AIRPORT
CHANGING THE BATTERY
The battery is housed on the right side of the grip frame. To
access the battery, remove the three screws holding the right
side grip panel down. Use a
3
⁄32” Allen wrench. Carefully lift the
battery out of the frame. When inserting a new battery notice the
+ and - marks on the board. The positive lead of the 9V battery
goes to the left and the negative lead to the right. Inserting the
battery backwards does not damage the board but it will not
function.
NOTE: If the marker will not function with the eye on, there is a
good chance the battery needs to be changed.
ON/OFF AIRPORT
The M8 comes equipped with an On/Off Airport
attached to the bottom of the frame. To turn on
the gas supply, twist the ON/OFF knob
clockwise, all the way in. To turn off the gas
supply, twist the ON/OFF knob
counterclockwise, all the way out. As you turn
the knob out, the residual gas between the
Hyper3™ and the ON/OFF airport is vented.

• A low battery will not be able to power both the ACE eye and the trigger switch, causing
ACE eye failure.
• If the battery is low, it may not be able to power the solenoid correctly. This will affect
the M8’s velocity, causing it to become inconsistent and/or low.
