SERVICE INSTRUCTIONS

Air Filter - Inspection and

Replacement

NOTE

Keep the air filter clean at all times. Do not operate the compressor with the air filter removed.

A dirty air filter will not allow the compressor to operate at full capacity. Before you use the compressor, check the air filter to be sure it is clean. If it is dirty, replace it with a new filter.

Oil - Checking and Changing

Overfilling with oil will cause premature compressor failure. Do not overfill.

1.Check oil level in compressor crankcase before each use. The oil level should be to the middle of the oil sight glass.

2.Replace the oil after initial 100 hours of operation - thereafter, every 300 hours of operation.

3.Remove the oil fill and drain plugs. Collect the oil in a suitable container.

4.Replace the oil drain plug and refill the crankcase with recommended oil. Always fill to middle of sight glass.

Note

It is important to maintain the proper oil level. A low oil level reduces proper cylin- der wall lubrication and increases ring wear.

5.Replace the oil fill plug.

6.Start the compressor outfit and run for several minutes. Shut the compressor down and check the oil level. If necessary, add more oil.

A compressor grade non-detergent oil should be used. Most automotive detergent oils cause excessive carbon buildup and should not be used. Please note that all units run at a constant speed (not start and stop) and should be lubricated by Rarus 847, Shell turbo 100, or Anderol synthetic compressor oil. Do not use synthetic oil for the first 300 hours. All units should be broken in on petro- leum based oil.

Check Valve - Inspection and Replacement

Remove and inspect the check valve at least once a year or more often if the compressor is heavily used. Moisture and other contaminants in the hot compressed air will cause an accumulation of a carbon-like residue on the working parts. If the valve has heavy carbon build-up, it should be replaced. Use the following proce- dure to inspect, clean or replace the check valve.

1.Turn compressor off and disconnect or lock out power source.

2.Release air pressure from the air tank.

3.Loosenthetopandbottomtubenutsandremovethe outlet tube.

4.Loosen pressure release tube nuts, disconnect from check valve and move tube aside.

5.Unscrew the check valve with a wrench.
