(2) Inspection of the amount of pump oil
Please replenish it with a prescribed pump as the pump oil side is in the range
of the red circle of the oil level gauge while driving.
(3) Inspection of oil leakage
When oil leak was caused by drain plug seal region, the exchange of the part is
necessary. Our specified O-rings and seals are always available from the service
departments shown at the back of this manual. When necessary, contact them.
(4) Inspection of abnormal sounds and vibration
Check the nuts and bolts for looseness.
(5) Inspection of the oil mist trap
When using the oil mist trap in replacement of the standard outlet port, pay
attention to the clogging of the filter in the oil mist trap.
If the clogging advances, evacuated gas cannot be exhausted any longer, which
causes the oil gauge to protrude and oil leakage from the shaft seal section or
drain plug seal section. The maximum internal pump pressure is 0.03 MPa (gauge
pressure).
When the pump is operated continuously for a long time or when the pump is extremely
contaminated with evacuated gas, overhaul is required. Contact the nearest sales or service
department among those listed at the back of this manual.
