MAINTENANCE AND INSPECTION INSTRUCTIONS
maintenance.
Check compressor often for any visible problems and follow maintenance procedures each time compressor is
used.
ASME Safety Valve
Check the safety valve by performing the following steps:
1. Plug the compressor in and run until shut off pressure is reached.
2. Wearing safety glasses, pull the ring on the safety valve to
release pressure from compressor tank. Use your other hand to
deflect fast-moving air from being directed toward your face.
3. The safety valve should automatically close at approximately
40 psi - 50 psi. If the safety valve does not allow air to be
released when you pull on the ring, or if it does not close
automatically, it MUST be replaced.
Drain Tank
1. Turn compressor off and release pressure from system. (To
release pressure from system, pull ring on ASME safety valve.
Deflect escaping air by shielding valve with one hand as you pull
ring with other hand.) Pull ring until tank is empty.
safety valve is opened with pressure in the tank. Wear ANSI
approved Z87.1 safety glasses.
2. Drain moisture from tank by opening drain valve underneath tank.
Tilt tank to remove all moisture.
3. Clean dust and dirt from tank, air lines and pump cover while compressor is still OFF.
Oil Change
1. Allow compressor to run and warm up oil. Unplug unit.
2. Position a pan under pump end of unit.
3. Remove drain plug. Allow oil to collect in pan. Tilt unit to completely drain.
4. Replace drain plug, fill pump to center of sight glass. Use Chevron synthetic 5W-30, Mobil 1 5W-30 or 10W-
30 synthetic motor oil. Using other types of oil will cause starting problems.
5. Change oil after every 50 hours of use.
Disconnect, tag and lock out power source then release all pressure
from the system before attempting to install, service, relocate or perform any
Do not remove or attempt to adjust the
safety valve!
Safety valve must be replaced if it cannot be actuated or it leaks air after ring is
released.
A large amount of
fast moving air will be released when the
