Section VI - Maintenance
Oil and oil filter change
Warning
CAUTION!
The operator must apply all relevant Safety precautions.
Always drain the vacuum pump oil at all drain points. Used oil left in the vacuum
pump can contaminate the oil system and can shorten the lifetime of the new oil.
Never mix lubricants of different brands or types as they may not be compatible
and the oil mix will have inferior properties. A label, indicating the type of oil filled
ex-factory, is stuck on the air receiver/oil tank.
Procedure
1. Run the vacuum pump until warm and stop the vacuum pump.
• Close the air inlet valve and switch off the voltage.
• Vent the vacuum pump by opening the plug (Ip) on the cover of the air inlet filter.
2. Remove the vent plug (VP) of the oil cooler.
3. Open the oil drain valve (Do).
Hold the oil drain hose (1) downward to drain the oil.
