• For the pumps that are attached with compressed air treatment equipment, empty the water

Maintenance
⚠WARNING
 Disconnect air hose and relieve air pressure before servicing.
Handling and storage of the pump do not require any special procedures. The dust in compressed air
can slow down or even block the motor cylinder. The following steps may prevent this from happening:
1) Add 50 grams of appropriate lubricating oil to the air inlet hole weekly; operate the pump for
several minutes after adding oil.
2) Turn on the pump for several minutes until the moving parts are fully lubricated. Repeat if
necessary. Do this on a weekly basis.
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, pay close attention to the lubricator's grease level
and refill with NLGL-2 conditions when necessary.
Keep the pump in a dry and cool place out of the reach of children.
Cleaning the Pump:
Operate the pump and drain off the oil, then the pump could be applied to other kind of oil.
