MAINTENANCE Before attempting any maintenance jobs on the compressor, make sure of the following
Note: Once a week: check oil level in the oil sump and see if it needs topping up.
• Master power switch is in “switched off” position.
For operation at ambient temperature in the range -5°C to +40°C, use synthetic oil. The advantage of this oil is that is does not lose its characteristics either in winter or summer.
• Make sure there is no pressure inside the air tank. Refer “Draining the condensate”.
Do not drain used oil into the sewer or dispose off in the environment.
OIL CHANGES – TOPPING UP WITH OIL
FOR OIL CHANGES TYPE OF OIL: Mineral Multi-grade (SAE 15 W40) with 100 hours duty.
The compressor is filled with synthetic oil. 1.
Unscrew the drain plug on the oil sump, allow all the oil to flow out, and re-screw the plug (FIG. 14).
2.
Pour oil into the upper hole of the oil sump until it reaches the centre red point on the oil lever indicator (FIG. 15).
3.
Push the dip stick back into the oil sump hole.
