Before removing the oil-drain or oil-fill plug always switch off the pump first
and vent to atmospheric pressure.
When the pump has become warm during operation the casing and the oil
temperature may exceed 80 °C.
Leave the pump to cool down. Always wear protective gloves also to pro-
tect yourself against aggressive residues in the oil.
Unscrew the oil-drain plugs the oil-fill plugs and drain the oil (see fig. 5.1).
Clean the sealing surface and firmly reinstall the oil-drain plugs using a gasket
which is in perfect condition. Wipe off any oil residues from the casing.
Fill in new oil. For this use a clean funnel.
For oil quantities and ordering data see Section 1.3.
Make sure to use the right kind of oil. PFPE pumps are marked with a red
label.
Only use Leybold oil.
