OPERATING THE SPREADER
There are two control options. They include the Variable
Speed (PWM) Control and the ON/OFF Control. The
variable speed control was redesigned. Identify old or
new style by the face plates shown for correct operating
instructions.
Variable Speed (PWM) Control – New Style
Starting and Stopping the Motor
1. To start the spreader motor, press the START/
BLAST button and release. Both the START/BLAST
and OFF buttons will be backlit when the motor is
running. The spreader will operate at the speed
selected on the speed dial.
2. Press the OFF button to stop the motor. The OFF
button operates as emergency stop when required.
NOTE: The truck ignition must be on to start the
spreader.
NOTE: If the truck ignition is turned off while the
spreader is running, 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. The speed will
increase as the number of green LED’s illuminated
on the speed dial increase.
2. Turning the speed dial counterclockwise will
decrease the speed.
Blast/Maximum Speed
1. Press and hold the START/BLAST button as long
as maximum speed is needed.
2. Release the button when maximum speed is no
longer needed. The control automatically returns to
the ON position and the speed shown on the speed
dial.
NOTE: When blast is used, the speed dial does not
move to the maximum speed setting, but remains
at the preset speed.
Diagnostic Indicator Light
The diagnostic indicator light located to the right of the
START/BLAST button remains dark unless a problem
with the motor or wiring is detected. The light will flash a
number of flashes in a row, pause, then repeat. Count
the flashes to determine the nature of the malfunction
and refer to the diagnostic chart below.
If additional information is needed, refer to the Trouble-
shooting section of this manual.
NOTE: Always place the cover on 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.
