* Just oil filtration in case of PFPE oil.
** 4000 running hours or 1 year or whatever comes first.
Note:
We recommend monitoring the oil condition through the sight glass and to
change the oil when it becomes discolored or milky. Not changing oil in time can
lead to premature blocking of the air exhaust filter and even failure of the vacuum
pump.
Also check for condensed water vapour on the bottom of the oil tank through the
oil viewer (high water handling capability versions only). If there is condensed
water vapour, open the oil discharge valve slightly, let the condensed water
vapour flow out and close it again as soon as oil starts to come out. Check the oil
level and top up if necessary.

CAUTION: LUBRICANTS COMPATIBILITY
Risk of injury and damage to equipment. A
void mixing lubricants of dif
ferent
brands or types as they may not be compatible and the oil mix will have inferior
properties. Always drain the pump as good as possible. Used oil left in the
pump shortens the lifetime of the new oil.
It is strongly recommended to use only the genuine recommended lubricants.
They are the result of years of field experience and research. Refer to Preventive
maintenance schedule on page 66 for the advised replacement intervals and
consult your spare parts list for part number information.
The pumps are delivered with the mineral vacuum pump oil, and synthetic oil as
an option.

In order to keep rubber parts and lip seals efficient and properly working, we
recommend you to operate the pump for at least 30 minutes every 6 months with
the intake closed.
