If not drained, water will corrode and weaken the air tank causing a
risk of air tank rupture.
NOTICE: Risk of property damage. Drain water from air tank may
contain oil and rust which can cause stains.
4.
After the water has been drained, close the drain valve (clock-
wise). The air compressor can now be stored.
NOTE: If drain valve is plugged, release all air pressure. The valve
can then be removed, cleaned, then reinstalled.
Compressor Pump Oil (Fig. 4)
NOTICE:
Risk of property damage. Use air compressor oil only.
Multi-weight automotive engine oils like 10W30 should not be used
in air compressors. They leave carbon deposits on critical compo-
nents, thus reducing performance and compressor life.
NOTE: Use full synthetic non-detergent air compressor oil.
NOTE: Crankcase oil capacity is approximately 49 fluid ounces
(1449 ml).
Checking
1.
The oil level should be to the middle of the sight glass (O).
2.
If needed remove oil fill plug (G) and slowly add oil until it
reaches the middle of the sight glass.
Changing
WARNING: Drain tank to release air pressure before removing
the oil fill cap or oil drain plug.
1.
Remove the oil fill plug (G).
2.
Remove the oil drain plug (H) and drain oil into a suitable con-
tainer.
3.
Replace the oil drain plug (H) and tighten securely
4.
Slowly add compressor oil until it reaches the middle of the
sight glass (O). NOTE: When filling the crankcase, the oil
flows very slowly into the pump. If the oil is added too quickly,
it will overflow and appear to be full.
CAUTION: Overfilling with oil will cause premature compressor
failure. Do not overfill.
5.
Replace oil fill plug (G) and tighten securely.

Belt Replacement
WARNING: This unit starts automatically. ALWAYS shut off the
main power disconnect, and bleed all pressure from the system
before servicing the compressor, and when the compressor is
not in use. Do not use the unit with the shrouds or belt guard
removed. Serious injury could occur from contact with moving
