11.After the water has been drained, close the drain cock or drain valve. The air
compressor can now be stored.
NOTE
Ifdrain cock valve is plugged, release all air pressure. The valve can then
be removed, cleaned, then reinstalled.
MAINTENANCE
Unit cycles automatically when power is on. During
maintenance, you could be exposed to voltage sources, compressed
air, moving parts, or hot surfaces. Personal injuries can occur. Unplug
the unit and bleed off all air tank pressure and allow unit to cool
before doing any maintenance or repair. Never operate the unit with
the belt guard removed.
To ensure efficient operation and longer life of the air compressor unit,a routine
maintenance schedule should be prepared and followed. The following routine
maintenance schedule is geared to an unit 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 units in an
extremely dirty and/or hostile environment will require a greater frequency of all
maintenance checks.
Routine Maintenance Schedule
Daily:
1. Pullring on safety valve allowing airto bleed from the tank untiltank pressure is
approximately 20 psi. Release safety valve ring.
2. Check oil level. Add if necessary.
3. Drain water from the air tank, any moistureseparators, or transformers.
4. Check for any unusual noise and/or vibration.
5. Manually check safety valve to make sure of proper operation.
6. Inspect air filter and replace if necessary.
7. Inspect air filter and replace if necessary.
Every 40 Hours of Operation:
1. Clean and inspect the air intake filter; replace ifnecessary.
2. Inspect condition of drive belt and replace if necessary.
Every 100 Hours of Operation:
1. Drain and refillcompressor crankcase with approximately 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, and adjust if necessary. (Refer to SERVICE INSTRUC-
TIONS in this manual.)
2, Inspect air lines and fittings for leaks; correct as necessary.
3. Check the alignment of the motor pulleyto the flywheel. If necessary, align to
within 1/32 inch on center line.
