Maintenance

1.After the first 10 hours of working, empty the crank case of oil and refill with clean oil by removing the crank case oil plug (left hand side of the crank case at the bottom)

Note. Use good quality compressor lubricating oil.

SAE30 or L-DAB 100 over 10°C

SAE10 or L-DAB 68 under 10°C

2.After each subsequent 500 hours of operation, again drain the oil and refill the crank case with clean oil.

3.After each day of operation unscrew the drain cock (10) under the tank to drain out any condensation that is in the tank. This will protect the tanks from rusting and prolong the product life. Once the draining has been completed screw the drain cock (10) closed.

4.Regularly check the air filter insert cartridge inside the air filter assembly (15) and clean or replace the insert when necessary.

5.Check daily the operation of the safety valve. This check should be performed when the tank contains close to max pressure in the tank.

To check the valve, pressurise the tank, and pull the ring OUTWARDS on the safety valve.

Air should discharge from the valve.

Release the ring of the safety valve. When the ring is released the air discharge must stop.

WARNINGS.

Safety glasses must be worn when performing this test.
