OPERATING THE SPREADER
DRIVING AND SPREADING ON SNOW
AND ICE
CAUTION
Drinking and then driving or spreading is
very dangerous. Your refl exes, perceptions,
attentiveness, and judgment can be affected
by even a small amount of alcohol. You can
have a serious or even fatal collision if you
drive after drinking. Please do not drink then
drive or spread ice-control materials.
Follow your vehicle owner's manual instructions for
driving in snow and ice conditions. Remember, when
you drive on snow or ice, your wheels will not get good
traction. You cannot accelerate as quickly, turning
is more diffi cult, and you will need longer braking
distance. Wet and hard packed snow or ice offer the
worst tire traction. It is very easy to lose control. You
will have diffi culty accelerating. If you do get moving,
you may have poor steering and diffi cult braking,
which can cause you to slide out of control.
Here are some tips for driving in these conditions:
• Drive defensively.
• Do not drink, then drive or spread ice-control
materials.
• Spread or drive only when you have good visibility
for operating a vehicle.
• If you cannot see well due to snow or icy
conditions, you will need to slow down and keep
more space between you and other vehicles.
• Slow down, especially on higher-speed roads.
Your headlamps can light up only so much road
ahead.
• If you are tired, pull off in a safe place and rest.
• The spreader's size and location reduce driver
visibility to the rear of the vehicle. We recommend
an OSHA compliant backup alarm for all governed
employers.
• Keep your windshield and all glass on your vehicle
clean to see around you.
• Dress properly for the weather. Wear layers of
clothing; as you get warm, you can take off layers.
Lit. No. 70445, Rev. 03 13 July 15, 2018
OPERATING THE SPREADER – CAB CONTROL
WARNING
Never operate equipment when under the
infl uence of alcohol, drugs, or medications that
might alter your judgment and/or reaction time.
WARNING
Never exceed 45 mph (72 km/h) when loaded
spreader is attached to vehicle. Braking
distances may be increased and handling
characteristics may be impaired at speeds
above 45 mph (72 km/h).

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 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 confi rmation code to
display.
NOTE: A brightness level setting of 12 or higher is
recommended for daylight conditions.
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 the control is ON and restart the calibration
process at Step 3.
Once the empty hopper setting has been calibrated,
the EH code will fl ash 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 Width 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.

OPERATING THE SPREADER
SPREADING TIPS
• Spread ice melters with the storm to prevent
unmanageable levels of ice.
• Never exceed 10 mph (16 km/h) when spreading.
• For a wider pass, increase spinner speed.
• For a heavier pass, drive slower.
• Never operate spreader near pedestrians.
• Calculate spread pattern when near vegetation.
NOTE: The spinner motor is not designed for
continuous duty. Allow the motor to cool between
long cycle times.
Lit. No. 70445, Rev. 03 19 July 15, 2018
MAINTENANCE
WARNING
Never remove the spreader with material in
the hopper.
CAUTION
Disconnect electric power at spreader
electrical wiring harness connection and tag
out if required before servicing or performing
maintenance.
CAUTION
• When replacing parts use only original
manufacturer's parts. Failure to do so will
void warranty.
• The control is a solid-state electronic unit
and is not serviceable. Any attempt to
service will void warranty.
• There are no serviceable parts in the
motor/transmission assembly. Any attempt
to service will void warranty.
• When pressure washing motor enclosure
area, keep spray at least 36" away from
motor enclosures.
AFTER EACH USE
CAUTION
DO NOT leave unused material in
hopper. Material can freeze or solidify,
causing unit to not work properly.
Empty and clean after each use.
• Wash out the hopper and rinse off all external
surfaces.
• Apply dielectric grease on all electrical
connections to prevent corrosion.
AT THE END OF EACH SEASON
OR AFTER EXTENDED STORAGE
• Wash out the hopper and rinse off all external
surfaces.
• Apply dielectric grease on all electrical
connections to prevent corrosion.
• Lubricate all grease fi ttings with good quality
multipurpose grease.
LUBRICATION
To keep your spreader running smoothly, observe the
following recommendations:
• Lubricate bearings after every 20 hours of use.
• Apply a small amount of light oil to latches as
needed.
• Oil or paint all bare metal surfaces.
• If motor cover is removed for any reason, use
silicone sealant to ensure weather proofi ng of
enclosure.
STORAGE
Unplug the cab control from the control harness at the
end of the season, or when the spreader is removed
from the vehicle. Store the spreader and cab control in
a clean, dry location, away from direct sunlight.
FUSE REPLACEMENT
See the Harness Wiring Diagram on the following
page for fuse ratings and locations.
If a problem should occur and fuse replacement is
necessary, the replacement fuse must be of the same
type and amperage rating as the original. Installing a
fuse with a higher rating can damage the system and
could start a fi re.
