or worn.
Regulator

Clean the ball detents. If necessary, apply a small amount
of grease around the outer surface to reduce friction inside
the ball detent covers. Replace if tips are worn down.
Lower regulator pressure.
Cycles very
slowly
Bolt or bolt
guide o-rings

grease.
Rate-of-fire

too low.
Loader may
not be
feeding fast.
Clean off old grease from the bolt and bolt guide o-rings,
as well as the bolt front seal, and apply fresh grease.
Raise rate-of-fire setting.
Check your loader’s batteries or use a faster loader.

Marker may

Dwell may be
set too low or
too high.
Check valve
may be missing.
Low pressures have difficulty supplying enough volume to
maintain a constant velocity. Do not lower your TM-15’s
regulator pressure below 180 psi.
Clean old grease from the poppet, the bolt and bolt guide
o-rings and apply fresh grease. Do not use too much, as it
will prevent the moving parts from cycling smoothly.
Reset the dwell setting to the factory default.
Make sure the check valve is in place.
Regulator
pressure
spikes
Regulator
adjusted too
high.
If the needle on the regulator’s gauge climbs well over 200
psi when attempting to install the air tank, first remove the
brass adjustment screw in the front of the regulator and try
again to install the air tank. If the needle reads 0, reinstall the
adjustment screw and turn in until the needle reads 200 psi.

Only fire paintballs with the marker’s eyes on.
Do a paintball drop test. On a level and smooth, hard, out-
door surface, such as concrete or asphalt pavement, drop
ten paintballs one at a time from about five feet high. Don’t
toss them up or throw them at the ground, just drop them
straight down. If more than three paintballs out of ten break,
the paintballs are bad and should not be used in the TM-15.
In the case of higher-end tournament-grade paintballs, it
may be possible to tune the TM-15 to successfully fire brit-
tle paintballs. Since all conditions are different, it is best to
ask for help with this from your local pro shop.
Try a different loader, such as the Empire Magna Drive
Loader. If using a Halo series or Empire Reloader B series
loader, try installing an Empire Magna Clutch Upgrade Kit.
Air blowing past worn o-rings can easily break paintballs in
the feed neck. Replace the bolt o-rings and the smaller 3-
bolt guide o-rings and apply fresh grease.
Make sure the bolt front seal is in place and has a light
application of grease to reduce friction.
Make sure the check valve is in place. Without the check
valve, the forward force on the bolt is too great and can be
too hard on the paintballs.
