Pumps are delivered in appropriate cardboard boxes. Packaging material should be
properly disposed.
Handling and storage of the new pump do not require any special procedures.
However after the pump has been used, empty the used oil in the suction tube into an
appropriate container. This is done by overturning the pump.
The dust in compressed air can slow down and even block the motor cylinder. The
following steps may prevent this from happening:
Add 50 grams of appropriate lubricating oil to the air inlet hole weekly; operate the
pump for several minutes after adding oil.
Turn on the pump for several minutes until moving parts are fully lubricated.
You may repeat the above operation if necessary.
The above steps should be carried out on a weekly base.
For the pumps that are attached with compressed air treatment equipment empty the
water retained in the reservoir of the filter-purger frequently.
For the pumps that are attached with a lubricator, please pay close attention to the
lubricator's oil level and refill with SAE 20, SAE 30 or antifreeze oil for extreme
conditions when necessary.
Maintenance
The user should perform only routine maintenance operations (filters, silencers, cleaning) to
avoid damaging the unit or compromising safety.
Contact our sales or service centers when the pump needs further maintenance.
We do not recommend that you repair the pump yourself.
