• 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) in or-
der to avoid compromising safety.
• Contact our sales or service centers when the pump needs further maintenance.
