Breaks
paint in
chamber Ball detents
may be dirty
or worn.
Regulator
pressure may
be set too
high.
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
may need
grease.
Rate-of-fire
setting may
be adjusted
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.
Inconsistent
velocity Pressure may
be set too low.
Marker may
need to be
greased.
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 TM7’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.
Inconsistent
velocity Battery may
be low.
Poppet o-ring
may be worn.
Replace battery with a fresh Duracell or Energizer brand
alkaline 9-volt.
Replace poppet o-ring and apply fresh grease.
Velocity
drops off
when firing
multiple
shots Air tank is not
screwed all the
way into the
TM7’s regula-
tor ASA. If during rapid firing the first ball comes out of the barrel at
full velocity and following shots decrease substantially,
watch the gauge on the TM7 regulator to see if the needle
drops down significantly and is slow to come back to the
set pressure. This is typically the result of not screwing your
air tank in enough. When screwing your air tank into the
TM7's regulator ASA, it is important to not stop as soon as
the marker pressurizes, but to continue turning until the air
tank stops. It is also acceptable to install the air tank when
it is empty, then have it filled by a professional while it is
installed. This will ensure that you get the maximum air
flow from your air tank.
Scratches
on bolt Spring may be
damaged. This can cause negative performance. The main spring should
be repaired by a trained technician or it can just be replaced.
Selector
switch not
working Selector may
be installed
incorrectly Check to be certain that the selector switch is installed with
keys facing down toward the trigger spring.
Leaks at
times while
shooting
multiple
shots Poppet may be
sticking open.
Battery may be
low.
Solenoid may
be sticking
open.
Clean the old grease from the poppet o-ring and apply
fresh grease. If that doesn't help, replace the poppet o-ring
and apply fresh grease.
Replace battery with a fresh Duracell or Energizer brand
alkaline 9-volt.
If the solenoid is sticking open occasionally, the regulator
pressure may be set too high. If the pressure is set to 200
psi or less, then the solenoid may be filled with dirt and/or
grease. See Maintenance section for instructions on how to
clean the solenoid.
