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 difficult, 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 difficulty accelerating. If you do get moving,
you may have poor steering and difficult 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.
CAUTION
Drinking and then driving or spreading is
very dangerous. Your reflexes, 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.

Lit. No. 68660/68661, Rev. 06 13 October 1, 2018

MAINTENANCE
PRESEASON CHECK
Before the unit is placed in service for the ice control
season, make sure that it is in top working condition.
Here are some tips for getting your spreader ready.
Remove the motor cap assembly and inspect the
following:
1. Check the condition of the drive belt. Any cracks
or damaged teeth indicate the need for a new belt.
See "Drive Belt Replacement" in this section.
2. Check the motor connection terminals for damage
or corrosion. Clean or replace as necessary and
coat with dielectric grease.
3. Check the condition of the drive shaft bearings by
first removing the drive belt. To remove the drive
belt see "Drive Belt Replacement" later in this
section. With the drive belt removed, spin the drive
shaft by hand. Any excess noise or roughness in
either bearing may indicate bearing failure.
4. If bearings pass inspection be sure to thoroughly
grease them with a good quality multipurpose
grease. See "Bearing and Set Screw
Maintenance" later in this section.
5. Verify that all drive sprocket set screws are tight.
Verify that all other fasteners are tight. Refer to the
torque chart in the Safety section of this manual.
6. Check the condition of the motor cap assembly
seal. This seal is very important to the reliability of
the unit. Replace the seal if needed.
7. Check the condition of the spinner disk. If the vanes
are excessively worn, the unit may not spread as
intended. Replace the spinner if necessary.
8. Replace the motor cap assembly and locknuts.
9. Verify that vehicle stoplights and spreader CHMSL
are visible and working properly.
AFTER EACH USE
Disconnect the electrical plug located between the
spreader and the truck before cleaning.
1. Thoroughly clean the unit inside and out using
tap water or a high-pressure washer. Avoid
spraying water into bearings, motor, and electrical
connections. A long-handled brush can be used to
aid cleaning.
2. Apply dielectric grease to all electrical connections
to prevent corrosion.
3. Lubricate the drive shaft bearings with a good
quality multipurpose grease.
CAUTION
• Do not operate a spreader in need of
maintenance.
• Before operating the spreader, reassemble
any parts or hardware removed for cleaning

TROUBLESHOOTING GUIDE
Problem Possible Cause Suggested Solution
Spinner does not spin.
No power to the spreader control.
Spreader control is turned OFF. Turn the spreader control ON.
Spreader control circuit breaker is
tripped (ON/OFF control only).
Turn the control OFF. Reset the circuit
breaker. Turn the control ON.
Battery lead in-line fuse is blown. Change the fuse and inspect for short
circuits.
Battery connection is poor. Clean or replace the ring terminal. Coat the
terminal with dielectric grease.
Battery wiring harness is damaged. Repair or replace the battery wiring harness
as required.
Spinner does not spin.
Motor is not turning.
12V DC power is present at the
Red wire to Red wire connection
located near the rear of the
spreader control.
Spinner, auger, or drive shaft is
jammed or overloaded.
Unplug the spreader harness. Turn the
spinner by hand. If the shaft will not turn
freely, check the spinner and auger for any
obstructions or frozen material. Clear all
obstructions.
Spinner shaft bearings are damaged. Unplug the spreader harness. Remove
the drive belt and turn the spinner by
hand. If the shaft will not turn freely, check
for obstructions. If no obstructions exist,
lubricate or replace the spinner bearings.
Motor is damaged. Turn the spinner by hand. If the shaft will
turn freely and the belt and pulleys are in
working order, check for 12V DC at the
orange wire to white wire connection located
near the motor. If the motor has 12V DC, the
problem is in the motor. Replace the motor.
Spreader control is damaged. Check for 12V DC at the white wire to white
wire connection at the back of the spreader
control. If the control does not have power,
the problem is in the control. Replace the
control.
Wiring harness is damaged. Check for 12V DC at the white wire to white
wire connection at the back of the spreader
control. If the control has 12V DC, check
for 12V DC at the white wire to orange
wire connection located near the motor. If
the motor does not have power, then the
problem is the spreader harness. Replace or
repair the harness as necessary.
Spinner does not spin when
load is applied.
Motor is turning.
Drive belt is loose or broken. Remove the motor cap and check for a
broken or loose drive belt. Tighten or replace
the belt as necessary.
