Operation - Graco B Series Instructions Manual

Operating the Agitator
Open and adjust the ball valve (1) until the motor is
running at the lowest speed needed to thoroughly agi-
tate the fluid. Excessive agitator speed may cause the
paint to foam.
If heavy or caked material in the center of the contain-
er is not being agitated, shut off the agitator and dis-
connect the air hose from the ball valve (1). Loosen
the screw (4) and adjust the angle of the agitator shaft
(18).
Lubricating the Bearing
During continuous operation, lubricate the bearing (10)
every week by injecting several drops of light lubricat-
ing oil into the hole (F) in the motor support (19). See
Fig. 2.

Operation

Cleaning the Shaft
Each week, clean any dried fluid from around the bear-
ing (10) and motor support (19) area of the shaft (18).
Lubricating the Air Motor
Not lubricating the air motor will cause air motor failure.
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.
