MAINTENANCE AND INSPECTION INSTRUCTIONS
Disconnect,
tag and lock out power source, then release all pressure from the system
before attempting to install, service, relocate or perform any maintenance.
Check compressor often for any visible problems and follow maintenance procedures each time
compressor is used.
ASME Safety Valve
Do not remove or attempt to adjust the 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.
Safety valve must be replaced if it cannot be actuated or it leaks air after ring is released.
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.
A large amount of fast moving air will be released when the 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.
Intake Air Filter Maintenance
Removal, Inspection and Replacement (Figure 6).
The intake filter element should be removed and
checked periodically. A clogged intake filter can
decrease compressor performance and cause the
compressor to overheat.
1. Remove
bolt.
2. Remove the filter cover and filter element. Inspect
each piece.
3. If the filter element is dirty or clogged, replace it.
4. Reinstall filter, cover, and bolt.
IMPORTANT:
Locate unit as far from spraying area as hose will allow to prevent overspray from clogging
filter.
End of operation/Storage
1. Turn AUTO/OFF switch to the
OFF
position.
2. Unplug power cord from wall outlet and wrap around handle to prevent damage when not in use.
3. Wearing safety glasses drain tank of air by pulling the ring on the safety valve. Use other hand to
deflect fast moving air from being directed toward your face.
4. Drain tank of condensation by opening drain valve on bottom of tank. Tank pressure should be below
10 psi when draining tank.
