The vacuum pump has a closed oil circuit. The oil reservoir is integral to the
pump housing. There is a sight glass on each side of the pump for
checking the oil level. The oil should reach at least the centre of the sight
glass.
Danger!
To prevent injury (burns) do not carry out the following work with the pump
still warm from operation, but wait until the pump has cooled down.
• Check the oil level of the vacuum pump in one of the sight glasses (1)
on either side of the pump and, if required, replenish oil through the
filling opening (2).
• Re-fit the housing cover.
Replenish only with clean oil and clean the pump housing before
replenishing to avoid contaminating the oil.
If the oil level in the sight glass is too high, water has accumulated in the
oil reservoir. This can occur if the machine is operated for only brief
periods or water has entered the intake line during cleaning. In this case,
change the oil.
