8.2 TOPPING UP OR CHANGING OIL IN THE VACUUM PUMP
To top up or change oil in the vacuum pump, the operator should use oils that are designed for use
in vacuum pumps.
To top up, the operator should unscrew the cap of the
vent (see illustration opposite) and top up with sufficient
oil to the level of the screw of the indicator light. Finally,
replace the cap on the vent.
To do a complete oil change it is necessary to:
- run the pump for 10 minutes;
- disconnect the machine from the power supply;
- disassemble the drainage cap positioned on the
underside of the pump; wait until all the oil has drained
out, and replace the cap.
- Unscrew the vent cap and fill up with new oil until the
level is halfway up the spyglass.
- replace the vent cap.
