Variable Speed (PWM) Control

Starting and Stopping the Motor

WARNING
Before starting the motor, be sure all
personnel and equipment are clear of the
discharge area.
1. To start the spreader motor, press the power
switch to the START/BLAST position and release.
This is a momentary position and the power switch
will automatically return to the ON position when
released. The spreader will operate at the speed
selected on the speed dial.
2. Press the power switch to the OFF position to stop
the motor. The power switch will remain in this
position. The power switch OFF position operates
as emergency stop when required.

spreader.
NOTE: If the truck ignition is turned off while the
spreader is running, the power to the motor will
stop.

Adjusting the Spinner Speed

The speed setting can be adjusted when the spreader
is either on or off.
1. Turn the speed dial clockwise. As the numbers
on the speed dial increase, so will the speed.
2. Turn the speed dial counterclockwise. As the
numbers on the speed dial decrease, so will
the speed.

Blast/Maximum Speed

1. Press and hold the power switch to the START/
BLAST position for as long as maximum speed is
needed.
2. Release the power switch when maximum speed
is no longer needed. When released, it will
automatically return to the ON position and to the
speed shown on the speed dial.
NOTE: When blast is used, the speed dial will
remain at the preset speed and will not move to
the maximum speed setting.

Spinner Indicator Lights

Two lights on the cab control indicate the status of the
motor:
• When the red (left) light is on, the power is on and
the motor is not running.
•
When the green (right) light is on, there is power to
the controller and the motor is running.
If there are problems while operating the spreader,
refer to the Troubleshooting section of this manual.
NOTE: Always place the vinyl cover over the
hopper to prevent moisture buildup. Do not let
the spreader sit idle with material in the hopper
for an extended period of time. This can cause
the material to compact and reduce or stop the
flow of material.
