DRIVING AND SPREADING ON SNOW
AND ICE
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dif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difcultyaccelerating.Ifyoudogetmoving,
youmayhavepoorsteeringanddifcultbraking,
which can cause you to slide out of control.
CAUTION
Drinking and then driving or spreading is
very dangerous. Your re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.
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.

Release the BLAST button. Press the ON/OFF button
twice (turning the spreader ON, then OFF) to save
the setting.
If auto-reverse is too sensitive or not sensitive enough,
the activation threshold can be reset. Repeat the
above procedure to select a value in the range of 5
to 8. Selecting a value of 10 or greater for a tailgate
spreader will disable the Ar feature.
Auto‑Reverse (Ar) Sequence
The Ar sequence will begin automatically, and consist
of a series of reverse-then-forward movements of the
auger.
The Arsequencewillmakeuptoveattemptsto
clearthejam.ThestatusdisplaywillashAr then a
number, and repeat as it counts down from 5 to 1. If
the jam is cleared, the auger will automatically return
to normal operation at the previous control settings.
If auto-reverse is unsuccessful, then the operator must
extract the material that is causing the problem. Follow
all warning directions when clearing jams.
CAUTION
Disconnect electric power and tag out, if
required, before servicing or performing

MAINTENANCE
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.
• For model 1875 spreader installations using the
pivot mount, keep the pivot assembly well greased
to prevent corrosion.
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ttingswithgoodquality
multipurpose grease.
• Oil or paint all bare metal surfaces.
• If motor cover is removed for any reason, use
siliconesealanttoensureweatherproo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re.
WARNING
Never remove the spreader with material in
the hopper.
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, stay at least 36" away from motor
enclosures.
CAUTION
Disconnect electric power at spreader
electrical wiring harness connection and tag
out if required before servicing or performing
maintenance.
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.
