• Never leave the pump or hoses filled with water or
air. To help prevent corrosion, flush the water and all

spirits or an oil-based solvent.

Agitators

To prevent air motor failure and possible damage to
equipment, always keep the air motor properly
lubricated using Air Motor Lubricant.
• After the first 100 hours, or two weeks of operation,
change the gear reducer oil. After that, change the
oil every 2500 hours, or six months (whichever
comes first) of operation under normal conditions.
More frequent oil changes are needed under severe
operating conditions or in atmospheres containing
excessive moisture or abrasives. See your agitator
manual for the oil changing procedure.
• If the air motor is operating sluggish or inefficiently,
flush the air motor (see your agitator manual).
• Every 2500 hours, or six months (whichever comes
first) of operation, inspect the bearing block (see
your agitator manual).
