Operation
Pressure Relief Procedure
1. Turn off the air regulator and close main air shutoff
valve.
2. Disconnect the air line from the motor air inlet.
Operate the Agitator
1. Fill the fluid supply container.
2. Start the agitator and run it slowly.
3. Use the needle valve (11) to regulate the agitator
speed. Set the agitator at a speed that minimizes
vibration.
NOTE: If an air shutoff valve is installed in the supply
line and used to stop the agitator, the same agitator
speed will be set each time the agitator is used. Part
numbers for Graco air shutoff valves are listed below:
4. Operate the agitator continuously while supplying
paints or other fluids to the system.
5. To stop the agitator, close the air valve in the air
supply line (if you have one), or close the agitator
needle valve (11).
Check Fluid Viscosity
If the agitator is in a closed drum, remove the agitator to
check fluid viscosity or siphon some fluid from the
3/4 npt drum port.
Maintenance
Lubricate the Air Motor
If an air line lubricator is not installed, the air motor must
be manually lubricated every 8 hours. Lubricate the agi-
tator air motor by placing 10 to 20 drops of SAE #10
lightweight oil in the motor’s air inlet. Run the agitator for
about 30 seconds.

NOTICE
Do not operate the agitator at a high speed for a long
period of time. Excessive agitator speed can cause
foaming of fluid (making the fluid unusable), vibration,
and increased wear on parts. Always agitate the fluid
only enough to maintain even mixing.
NOTICE
Not lubricating the air motor will cause air motor failure.
