• 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, 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
order not to damage it or compromise its safety.
• Contact our sales or service centers when the pump needs further maintenance.
• We do not recommend that customers repair the unit.
