To ensure efficient operation and longer life of the air compressor outfit, a routine maintenance schedule should be
prepared and followed. The following routine maintenance schedule is geared to an outfit in a normal working
environment operating on a daily basis. If necessary, the schedule should be modified to suit the conditions under which
your compressor is used. The modifications will depend upon the hours of operation and the working environment.
Compressor outfits in an extremely dirty and/or hostile environment will require a greater frequency of all maintenance
checks. Lubricate compressor motor (if required) according to manufacturer's instructions, which are attached to your
Engine Owners Manual.
Every 100 Hours of Operation:
1. Drain and refill compressor crankcase with 16 fluid
ounces (473.2 ml) of clean compressor oil or Castrol
Heavy Duty 30 weight.
2. Increase frequency of oil changes if humidity or
operating conditions are extreme.
Every 160 Hours of Operation:
1. Check drive belt tension; adjust if necessary.
(Refer to SERVICE INSTRUCTIONS in this manual.)
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
centerline.
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.
