Maintaining the drivetrain (every 10,000 shots)
To maintain your drive, ensure your marker is fully degassed and pull the drive cover up to
release the drive. Slide the drive out of your marker. Unscrew the drive parts to access the
2
components shown in the diagram below.
Clean the old grease and dirt from the keg, bolt and valve. Apply fresh Militia Lube to the keg
inner o-rings (#17 and #19). Apply fresh lube to the #M16-2 o-ring on the bolt, as well as the
inside of the larger end of the bolt. Slide the bolt back into the keg. Apply fresh lube to the
#14 o-ring on the valve and slide it into the bolt, then screw the valve into place. Complete
the drive assembly by screwing the valve cap back onto the valve. Lightly regrease the outside of the drive and slide it
back into your marker.

the piston shaft, and the #11 o-ring on the piston, as well as the #8 o-ring.
Apply new grease to the inside of the frame bore before re-installing your regulator.

The piston may not come out with the regulator
body. Never use pliers or any tool to grab the piston,
this can damage it. Use a 1/8" allen key pushed into
