8. MAINTENANCE
(7) Inspecting the drainage solenoid valve
If the drainage solenoid valve does not function correctly, water will not drain properly
and can enter the pneumatic drive section to cause a malfunction. If water is not
drained, rust remains in the air tank, resulting in the clogging of the filter regulator,
Y-type strainer and drainage solenoid valve to cause a malfunction.
Remove the drainage solenoid valve (see “8-3-9 (3) Removing and in-
stalling the solenoid valve for drainage”).
Cut the cable tie attached on the drainage solenoid valve, and dismount the
head.
After dismounting the head, inspect the spring, seat and O-ring. If the O-ring is
damaged, replace the solenoid valve.
Pour water from the top section of the main body to wash off dust particles from
the mesh screen
Check to make sure that the O-ring is free of scratch or damage. Check that the
seat has no dust particles. Make sure that the spring is inserted all the way.
To reinstall, follow the removal sequence in reverse.
