Warning! High Temperatures!
Rotary pumps run hot during operation.
Allow pumps to cool before draining oil.
The oil level in the rotary pump should be checked in accordance
with the maintenance schedule and replenished if necessary. If a
significant loss of oil has occurred, this should be investigated
according to instructions provided by the pump manufacturer
(manual supplied).
Routine oil changes are not required for rotary pumps filled with
Fomblin oil.
