Every 160 Hours of Operation:
1.Check drive belt tension; adjust if necessary.
2.Inspect air lines and fittings for leaks; correct as necessary.
3.Check the alignment of the motor pulley to the flywheel. If necessary, align to within 1/32 inch on center line.
Each Year of Operation or if a Problem is Suspected:
Check condition of air compressor pump intake and exhaust valves. Replace if damaged or worn out.
SERVICE INSTRUCTIONS
Air Filter - Inspection and Replacement
NOTE
Keep the air filter clean at all times. Do not operate the air compressor with the air filter removed.
A dirty air filter will not allow the air compressor to operate at full capacity. Before you use the air 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 air compressor pump failure. Do not overfill.
1.Check oil level in air compressor crankcase before each use. The oil level should be even with the top of the fill hole and must not be allowed to be lower than 3/8" from the top (6 threads) at any time.
2.See Routine Maintenance Schedule for oil change scheduling.
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.
Note
It is important to maintain the proper oil level. A low oil level reduces proper cylinder wall lubrication and increases ring wear.
5.Replace the oil fill plug.
6.Start the air compressor unit and run for several minutes. Shut the air compressor down and check the oil level. If necessary, add more oil.
