(3) Pump oil amount inspection
Add the specified pump oil as necessary to ensure that the pump oil level is always
within the red circle on the oil level gauge during operation.
(4) Oil leak inspection
If oil leaks from the drain plug seal, replace the seal. The necessary o-rings and
seals are kept in stock at the service departments listed at the end of this manual.
Contact them as necessary.
(5) Intake metal mesh inspection
Dust, etc. contained in the intake gas can clog the metal mesh and reduce the pump
performance.
(6) Abnormal noise and vibration inspection
Check that there are no loose nuts and bolts, etc.
(7) Oil mist trap inspection
When using an oil mist trap instead of the standard exhaust port, pay attention to
whether the filter inside the oil mist trap is clogged or not. If the filter becomes too
clogged, the exhaust gas will not have any way to escape and the pressure inside
the pump will rise. This can lead to oil spraying from the oil level gauge, and oil
leaking from the drain plug seal, etc. The internal pressure limit of this pump is
0.03 MPa (gauge pressure).
In addition to the above inspection items, disassemble and repair the pump if it has been used
continuously for a long time or if there is severe contamination due to the intake gases. Contact
your nearest dealer or the service division (see last page of this manual).
