CHECKING PUMP OIL AND PUMP OIL
CHANGING
NOTE:
The oil in the pump is a special
synthetic type and must only be
replaced by the exact same type. See
the pump parts lists for the type of oil
to order.
Some pumps have an oil sight glass to
check the pump oil level. The oil level
should be at about the middle of the
sight glass. It may be difficult to see the
oil, so tilting the unit some may help to
find the level line of the oil.
If the pump does not have a sight glass,
then the oil level cannot be checked.
Normally, it is not necessary to change
the oil in the pump.
If there is a noticeable amount of oil
that is leaking from the pump, then the
oil seals may be worn or damaged and
the unit should be taken to an autho-
rized Campbell Hausfeld Service Center
for repair.
