MAINTENANCE
If you take 10 minutes after every day of play to maintain your marker, you will be rewarded with consistent reli
-
able performance.
You should perform basic cleaning after every day of play, and you should perform drivetrain maintenance every
5 cases. You should perform inline regulator maintenance every 20 cases. You can clean and maintain your marker
more often, it is up to you.
When maintaining your marker, use only MacDev accessories. Your marker is packaged with an allen key set and a
small tube of MacDev Militia Lube, only use Militia Lube for lubrication.
Basic cleaning
After using your marker, always clean old paint from the outside. Always clean your barrel using a barrel swab to
remove traces of dirt and paint. Use your barrel swab to clean the breech and feed tube in a similar way.
Your marker internal parts are quite well protected and sealed. However, when not in use, dirt can get into the
marker and cause problems - so storage of your marker is just as important as cleaning. When storing your marker,
ensure that it is stored a bag that is free of dirt, otherwise dirt may get into the venting ASA or breech.
Maintaining the drivetrain
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 Prime. Unscrew the drive parts to access the 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.
When the drive is re-assembled, push the drive cover up and down to ensure the detent and spring are working
correctly. Lightly regrease the outside of the drive and slide it back into your Prime marker.
More detailed drawings of the sub assemblies are available from macdevpaintball.com/support.
