BOLT MAINTENANCE
Regular FL-21™ bolt maintenance is vital to the performance of the M3s. If
the FL-21™ bolt is not kept well greased and the O-rings in good shape, the
performance of the M3s will be greatly hindered.
The M3s software tracks how many shots the marker has fired, and will
alert you when service is due. A red service icon will flash over the playing
screen. See service system on page 8 for more info.
USE DYE UL SLICK LUBE TO GREASE THE M3S FL-21™ ENGINE
AFTER EVERY 4,000 TO 8,000 SHOTS, DEPENDING ON PLAYING
CONDITIONS. CHECK CONDITION OF O-RINGS. BE SURE THE FL-21
BOLT CAN MOVE BACK AND FORTH WITHOUT EXCESSIVE FORCE.
To remove the bolt, grab the bolt back cap with your right hand. Push the
bolt release button, located on the left side of the bolt back cap, with your
thumb. With the bolt release button depressed pull firmly back on the bolt.
BEFORE INSTALLING THE BOLT INTO THE MARKER, BE SURE ALL
BOLT COMPONENTS ARE SCREWED TOGETHER SNUGLY.
If you do not grease the bolt, you will run the risk of damaging O-rings. This
will create excessive friction and drag on the bolt, ultimately resulting in
breaking the bolt. When greasing the M3s FL-21™ bolt, pay special attention
to all O-rings that are on the bolt and that ride on a surface of the bolt.
