Operation
Operation
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).
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:
| Air Shutoff Valve |
Part | Description |
|
|
208390 | 1/4 npt(m) x 1/4 npt(m) |
|
|
208391 | 3/8 npt(m) x 3/8 npt (f) |
|
|
208392 | 3/8 npt(f) x 1/4 npt(m) |
|
|
208393 | 3/8 npt(m) x 3/8 npt (m) |
|
|
4.Operate the agitator continuously while supplying paints or other fluids to the system.
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.
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
NOTICE
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 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.
