Operation – Electric Motor
The agitator speed is fixed for electric motor models;
the specific speed depends on the model type. See
Technical Data on page 27 for electrical requirements
for your model type.
1. To start the agitator, turn on electric power to the
motor.
2. To stop the agitator, turn off electric power to the
motor. Disconnect electric power before checking
or servicing the agitator.
NOTE: The motor has thermal protection circuitry
which shuts down the motor if overheating occurs. If
this happens, disconnect power and recheck your
wiring connections and electrical supply.
WARNING
MOVING PARTS HAZARD
The thermal protection circuit resets
automatically when the motor cools
down. To reduce the risk of injury or
damage to equipment, always disconnect the
power supply before checking or servicing the
agitator motor.
Operation – Air Motor
The agitator speed for air motor models is variable
over a certain range, depending on the model type.
See Technical Data for your model type on page 27.
1. To start the agitator, turn on the air supply and
slowly open the air needle valve.
2. To stop the agitator slowly close the air needle
valve.
Turn off the air supply and disconnect the air hose
from the air motor before servicing the agitator.
Operation
Operation – Hydraulic Motor
The agitator speed for hydraulic motor models is
variable over a certain range, depending on the model
type. See Technical Data for your model type on page
27.
To start the agitator:
1. Open the shutoff valve at the hydraulic return line.
2. Open the shutoff valve on the hydraulic supply line
to the agitator.
3. Adjust the regulator to increase or decrease the
agitator speed.
4. To stop the agitator, close the hydraulic shutoff
valve in the hydraulic supply line.
Disconnect the power supply before checking or
servicing the agitator.
Pressure Relief Procedure.
Hydraulic Pressure Relief Procedure
For hydraulic agitators, always follow this procedure
whenever you shut off the agitator and before inspect-
ing, removing, cleaning or repairing the agitator, to
reduce the risk of serious bodily injury, including
splashing in the eyes or on the skin, and injury from
moving parts.
1. Shut off the main hydraulic power supply.
2. Close the regulator to the motor.
3. Shut off the hydraulic return valve.
4. Disconnect the hydraulic lines to the agitator.
WARNING
PRESSURIZED FLUID HAZARD
To reduce the risk of serious injury, such
as fluid injection or splashing fluid in the
eyes or on the skin, follow the Hydraulic
