SERVICE AND ADJUSTMENTS

ALL MAINTENANCE AND REPAIR OPERATIONS NOT LISTED MUST BE PERFORMED BY TRAINED SERVICE TECHNICIAN.

Risk of Unsafe Operation. Unit cycles automatically when power is on. When servicing, you may be exposed to voltage

sources, compressed air, or moving parts. Before servicing unit unplug or disconnect electrical supply to the air compressor, bleed tank of pressure, and allow the air compressor to cool.

To Replace or Clean Check Valve

1.Release all air pressure from air tank. See "To Drain Tank" in the Maintenance section.

2.Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank.

3.Using an adjustable wrench loosen outlet tube nut at air tank and pump. Carefully move outlet tube away from check valve.

4.Using an adjustable wrench loosen pressure relief tube nut at air tank and pressure switch. Carefully move pressure relief tube away from check valve.

5.Unscrew the check valve (turn counterclockwise) using a 7/8" open end wrench. Note the orientation for reassembly.

6.Using a screwdriver, carefully push the valve disc up and down. NOTE: The valve disc should move freely up and down on a spring which holds the valve disc in the closed position, if not the check valve needs to be cleaned or replaced.

7.Clean or replace the check valve. A solvent, such as paint or varnish remover can be used to clean the check valve.

Screwdriver

In open position nothing is visible.

In closed position disc is visible.

8.Apply sealant to the check valve threads. Reinstall the check valve (turn clockwise).

9.Replace the pressure release tube. Tighten nuts.

10.Replace the outlet tube and tighten nuts.

11.Perform the Break-in Procedure. See "Break-in Procedure" in the Operation section.

Additional Service

Disassembly or service of the air compressor beyond what is covered in this manual is not recommended. If additional service is required, contact your near- est Authorized Warranty
