Operation

Pressure Relief Procedure

1. Close the needle valve (11) and close the main air 

shutoff valve (A). Turn off the air regulator, if 
equipped.

2. Disconnect the air line from the motor air inlet.

Operate the Agitator

1. Fill the fluid supply container.

2. With the needle valve (11) in the closed position, 

open the master air valve (A).

3. Start the agitator by slowly opening the needle valve 

(11) and run it slowly.

NOTE:

 For best performance, ensure the shaft and 

blades are spinning counter-clockwise when viewed 
from above. The direction of rotation can be changed by 
reversing the position of the air inlet and muffler on the 
motor.

4. 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.

5. Operate the agitator continuously while supplying 

paints or other fluids to the system.

6. To stop the agitator, close the master air valve (A) 

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.

To avoid personal injury due to moving parts, never 
operate the agitator outside of a drum.

This equipment stays pressurized until pressure is 
manually relieved. To help prevent injury from 
pressurized fluid, such as splashing fluid and moving 
parts, follow the Pressure Relief Procedure when you 
stop dispensing and before cleaning, checking, or 
servicing the equipment.

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.
