TSM-35 Screw Pocket Machine Troubleshooting
**** Drain the air tank with the drain cock prior to
working on the pilot valve. We recommend purging the air
lines and tank to remove as much debris as possible.
To confirm that there is air reaching the pilot valve:
• Remove main air from machine
• Use the drain cock to drain the air tank
• Remove the pilot valve from the large red hose that
supplies air from the air tank
• Place a towel over the fitting on the red hose and
reattach main air to the machine **CAUTION – air
and air tool oil should immediately blow from the
red hose, make sure the hose is secure when main
air is reattached.
o If air does blow from the hose, the pilot
valve needs to be replaced.
o If there is no air out of the hose, then the
issue is with the air supply to/from the air
tank. Check the lubricator to make sure it is
providing air, check the check valve to make
sure it is allowing air through, check to
make sure the air tank is able to hold air
and deliver air, check the red hose from the
tank to make sure it is not blocked.
• If air comes out of the fitting from the pilot valve / hose assembly:
o Place a towel over the fitting and override the solenoid again. Look
for debris and or air tool oil on the towel.
If there is visible debris:
• Replace the pilot valve (P35250
)
• Check the screen in the back of the air drill. If there
is visible debris, replace the air drill (P01957
)
