Check Valve Replacement
1.Release all air pressure from air tank and unplug outfit.
2.Remove shroud.
3.Loosen the top and bottom nuts and remove the outlet tube.
4.Remove the pressure release tube and fitting.
5.Unscrew the check valve using a socket wrench.
6.Check that the valve disc moves freely inside the check valve and that the spring holds the disc in the upper, closed position. The check valve may be cleaned with a strong solvent.
7.Apply sealant to the check valve threads. Reinstall the check valve.
8.Replace the pressure release tube and fitting.
9.Replace the outlet tube and tighten top and bottom nuts.

Motor
The motor has an automatic reset thermal overload protector. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before restarting. The compressor will automatically restart after the motor cools.
If the overload protector shuts the motor off frequently, check for a possible voltage problem. Low voltage can also be suspected when:
1.The motor does not get up to full power or speed.
2.Fuses blow out when starting the motor; lights dim and remain dim when motor is started and/or is running.

STORAGE
Before you store the air compressor, make sure you do the following:
1.Review the "Maintenance" section on the preceding pages and perform sched- uled maintenance as necessary.
2.Set the “ON/AUTO” lever to “OFF”.
3.Turn the regulator counterclockwise and set the outlet pressure to zero.
4.Remove the air tool or accessory.
5.Pull ring on safety valve allowing air to bleed from the tank until tank pressure is approximately 20 psi. Release safety valve ring.
6.Drain water from air tank by opening drain cock valve on bottom of tank.
WATER WILL CONDENSE IN THE AIR TANK. IF NOT DRAINED, WATER WILL CORRODE AND WEAKEN THE AIR TANK CAUSING A RISK OF AIR TANK RUPTURE.
7. After the water has been drained, close the drain cock or drain valve.
NOTE
If drain cock valve is plugged, release all air pressure. The valve can then be removed, cleaned, then reinstalled.
8.Protect the electrical cord and air hose from damage (such as being stepped on or run over). Wind them loosely around the compressor handle. (If so equipped)
Store the air compressor in a clean and dry location.
