DETERMINING VEHICLE PAYLOAD
1. Install the hopper spreader and optional equipment
according to the Installation Instructions.
2. Install or attach any other equipment that will be
on the vehicle while the hopper spreader will be in
use (step bumper, trailer hitch, snowplow, etc.). Fill
gas tanks.
3. Obtain the Gross Vehicle Weight Rating (GVWR),
Front Gross Axle Weight Rating (FGAWR), and
Rear Gross Axle Weight Rating (RGAWR) from
the certification label located inside the driver-side
door jamb or door.
4. With the occupants in the vehicle for normal
hopper spreader operation, weigh the vehicle to
obtain gross vehicle weight (GVW).
5. Subtract the GVW from the GVWR to determine
the available material payload.
6. Obtain the weight per cubic yard (lb/yd3) of the
desired material. Divide the weight into the
payload to determine the maximum volume of
material that can be carried.
7. Refer to the Load Volume table and diagrams to
determine the maximum fill level for the material.
8. Fill the hopper with material to the calculated level.
Reweigh the vehicle with occupants and verify that
the Loaded Gross Vehicle Weight, Front Gross
Axle Weight, and Rear Gross Axle Weight are less
than the vehicle's ratings.
9. Repeat Steps 6−8 for each type of material.
The worksheet for Determining Vehicle Payload (next
page) includes an example.
WARNING
Overloading could result in an accident or
damage. Do not exceed GVWR or GAWR
ratings as found on the driver-side door

OPERATING THE SPREADER – CAB CONTROL
SETUP PROCEDURES
Calibrate Empty Hopper Setting
(Cb and EH Codes)
Calibrating the empty hopper setting enables the cab
control to alert the operator when the hopper is empty.
Recalibrate the empty hopper setting at the start of
each ice-control season.
1. Verify that the hopper is empty before beginning
the calibration.
2. Turn the vehicle ignition to ACC or ON. Press
the ON/OFF button on the cab control to turn the
control ON.
3. Press and hold the Material Width (left) knob
for approximately 10 seconds until the Cb code
displays.
4. The calibration cycle will begin. The blue LEDs
around the Material Flow (right) knob will illuminate
in succession until all eight are lit.
5. When the automatic calibration cycle is complete,
the control will automatically revert to the previous
material application settings.
If the control is turned OFF or loses power during the
calibration cycle, the calibration data will be lost. Make
sure that the control is ON and restart the calibration
process at Step 3.
After the empty hopper setting has been calibrated,
the EH code will flash on the display and a beep will
sound whenever the hopper is empty. The EH code is
informational only and will not stop spreader operation.
Clearing Empty Hopper Calibration Data (Cc Code)
The empty hopper calibration may be cleared,
if desired. The control will no longer display the
EH status code when the hopper is empty.
Start the calibration cycle as described above. At
Step 4, press the Material Flow (right) knob during
the calibration cycle to clear all calibration data. The
Cc (Clear Calibration) code will display and the control
will exit Cc mode automatically.
Adjust LED Brightness Level
(LS and SL Codes)
The brightness setting of the cab control lights can be
adjusted from 1 to 16. The factory default setting is 8.
1. Turn the vehicle ignition to ACC or ON. If
necessary, press the cab control ON/OFF button
to turn the control OFF.
2. Press and hold the Material Width (left) knob for
approximately 3 seconds until the LS code is
displayed.
3. Release the knob and turn it clockwise or
counterclockwise to increase/decrease the
brightness level. The light level number will show
in the status display.
4. After selecting the desired brightness level, wait
a few seconds for the SL confirmation code to
display.
NOTE: A brightness level setting of 12 or higher is
recommended for daylight conditions.
