7. Maintenance
7-1 Suction filter
Replace the suction filter once a year or clean it
periodically.
Before conducting maintenance on the pump, turn
off the power and make sure that the pump is not
operating. Conducting maintenance with the
power turned on will increase the risk of the
operator getting an electric shock or the fingers
being pinched in moving parts of the pump drive
unit. Also make sure that the supply of air is cut at
the air supply source.
If the suction filter is clogged or contaminated, the
oil suction performance will deteriorate and
lubricating oil will not be able to reach points of
lubrication.
