CAUTION
If the oil level is lower than the lower limit line of the oil level gauge in daily
inspection and maintenance, it is necessary to supply oil.
Follow the steps below to supply oil.
(1) Stop the pump and remove the outer side cover on the pump. (See Fig. 8.1)
PM10U
Do not start filling oil until the interior pump pressure has
reached atmospheric pressure. The chamber containing the oil
is under low pressure (vacuum) so that a significant leak will
occur causing substantial damage to the pump when the
oil-filling plug is removed with the pump operating.
Waste oil shall be disposed of by industrial waste disposal
dealer in accordance with Material Safety Data sheets.
