serious injury or property damage.
If the air motor is sluggish or inefficient, follow this
procedure in a well ventilated area.

Disconnect the air line and muffler (08) from the
motor (W).
2.
Add several teaspoons of non-flammable solvent,
or spray the solvent directly into the motor air
tube connector (R).

Reconnect the air line, and slowly increase the
air pressure until there is no trace of solvent in
the exhaust air.

To prevent air motor failure and possible damage
to equipment, always keep the air motor properly
lubricated.
If an air line lubricator is not installed, the air motor
must be manually lubricated every 8 hours. Lubricate
the agitator air motor by placing 10–20 drops of SAE
#10 light oil in the motor’s air inlet. Run the agitator
for about 30 seconds.

After the first 100 hours or two weeks
of operation, remove the oil plug (T) and the oil
level plug (S), drain the oil, and thoroughly flush the
housing with light flushing oil.
Refill with Graco oil (part 217374) to the proper level.
Afterward, change the oil every six months or
2500 hours of operation (whichever occurs first)
under normal operating conditions. More frequent
oil changes are needed under severe operating
conditions or in atmospheres containing excessive
moisture or abrasives. Contact your Graco distributor.

Every six months or 2500 hours of operation
(whichever comes first), inspect the bearing block
(BR). This can be performed before or after gear
reducer oil changes.
With the agitator running slowly, place a hand on the
side of the bearing block (BR). There should be no
excessive vibration or grinding. Do not attempt to
repair the bearing block or gear reducer. Contact
your Graco Distributor.
