MARKER EXHIBITS FIRST SHOT DROP-OFF (FSDO)
• FSDO is a low velocity, or non-firing first shot, followed by normal shooting and is often
caused by debris in the bolt or a poorly lubricated bolt. Clean the bolt, breech, bolt stop
and bolt sleeve, and lubricate them with GR33SE
TM
as instructed in the Field Stripping
section of this manual.
• FSDO can also be caused using the CO
2
dwell setting with compressed air. Follow the
dwell selection instructions in this manual and ensure that the correct dwell setting has
been set for the type of gas being used.
MARKER EXHIBITS INCONSISTENT VELOCITY OR DROPS OFF SIGNIFICANTLY
DURING RAPID FIRING
• Check paint quality. Your marker is optimized for use with fresh, high-quality paintballs.
Paintballs of inconsistent quality, or paintballs that have been exposed to humidity or
temperature extremes may vary in size or roundness causing inconsistent operation.
• Gas could be low. Fill gas source and make sure gas supply is turned on.
• Battery may be low. This will be most noticeable with velocity dropping and then entire
shots not firing during rapid fire. Replace battery with a new name brand alkaline battery.
• Regulator may be contaminated or damaged. Follow the instructions in this manual or
see a GOG Paintball
TM
technician for service.
• Liquid CO
2
may be entering the regulator – see the gasses section of this manual for
guidance in proper CO
2
set-up.
