CHECKING THE OIL
WARNING:
Drain the tank to release the air pressure
before removing the oil fill cap or oil drain plug.
CAUTION:
Overfilling with oil will cause premature air
compressor failure. Do not overfill.
NOTICE
:
Risk of property damage. Use air compressor oil only.
Multi-weight automotive engine oils like 10W30 should not be
use in the air compressors. They leave carbon deposits on critical
components, thus reducing performance and compressor life.
□
The oil level should be to the middle of the sight
glass (2).
□
If needed, remove the oil fill plug (1) and slowly
add the oil until it reaches the middle of the sight
glass.
NOTE:
Use 30W compressor oil or a heavy duty SAE
30W, non-detergent, SF grade or better oil. Do not use
multi-weight automotive engine oils, as they will reduce
compressor life. Under extreme winter condition use
SAE-10 weight oil.
CHANGING THE OIL
□
Remove the oil fill plug (1).
□
Remove the oil drain plug (3) and drain the oil
into a suitable container.
□
Replace the oil drain plug (3) and tighten
securely.
□
Slowly add the compressor oil until it reaches
the middle of the sight glass (2).
NOTE:
Crankcase oil capacity is approximately 48.5 fluid
ounces (1.4 liter).
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.
□
Replace the oil fill plug (1) and tighten securely.
