WARNING
!
Never assume a compressor is safe to work on just because it is not operating. It could
restart at any time. Follow all safety precautions and guidelines outlined in this manual.
CRANKCASE OIL -
The oil level should be half way to three quarters up the sight gauge
when the compressor is stopped.
Do not over fill or check the oil level while the pump is running. Compressor must be
level.
Use
, petroleum based, compressor or automotive grade oil
.
Detergent or synthetic oil can damage the pump, cause excessive leaks, and will void
the warranty.
non-detergent
only
DO NOT USE SYNTHETIC OIL IN THIS PUMP !

NOTE:

-
Change the air filter element every 300 working hours or quarterly. (Whichever occurs first).
Fasten bolts and nuts as required.
- Change oil more frequently if compressor is located in a very dirty environment.
Test and calibrate the pressure switch, pressure gauge and ASME safety valve according to their own technical
standards. These parts must be removed from the tank and pump to be tested.
Inspect and clean the suction and discharge valve(s) plate(s) every 1000 (one thousand) working hours (whichever
occurs first), located between the cylinder and its cover and, if necessary, replace it (them) according to the operation
conditions.
- The first oil change should be made after 8 hours of operation.
- The second oil change after 40 hours of operation.
- The third and following oil changes should be made after 200 hours of operation, or 60 (sixty) days, whichever occurs
first.
Heavy Duty and multi-viscous oils are not adequate for Schulz air compressor's lubrication. The same applies to oils that
tend to emulsify.
We recommend good industrial oil for air compressors, with rust and oxidation inhibitors and high viscosity level (from 90 to
95), SAE or ISO, as indicated in the table below:
- WHILE RUNNING IN A PERIOD OF ABOUT 100 WORKING HOURS THE OIL LEVEL SHOULD BE CAREFULLY
CHECKED.
