8.4 Lubricant Oil

CAUTION
CAUTION
If the oil level is lower than the lower limit line of the oil level gauge in daily
inspection and maintenance, supply the oil is needed.
Follow the steps below to supply the oil.
(1) Stop the pump and remove the outer side cover on the pump.
(2) After you have waited until the internal pump pressure returns to atmospheric
(normal) pressure, remove the plug from the oil-filler inlet. (See Fig. 8.1.)
(3) Check the oil level from the sight-glass of the oil level gauge and fill lubricant
oil until its level reaches the top line. (See Figs. 8.1. and 8.2.)
(4) After you have checked that there are no depositions and fragments adhering
to the O-ring attached to the plug, close the oil-filler inlet.
(5) Fit a waste oil container (PVC bag) to the bottom of the oil drain hole of the
secondary reservoir and remove the drain plug. (See Fig. 8.1.)
(6) When you have drained off the waste oil close the drain hole after you have
checked that there are no depositions and fragments adhering to the O-ring attached
to the plug.
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. (Appendix 1,2)
