OPERATING THE SPREADER  
Driving and Spreading on Snow and Ice  
Accessory Circuit  
The yellow wire in the vehicle harness is provided for  
accessory use of 12 amps or less.  
CAUTION  
Drinking and then driving or spreading is very  
dangerous. Your reflex, perceptions,  
attentiveness and judgement 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 difficult and you will need longer braking distance.  
Wet and hard packed snow or ice offers 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.  
• Spreader size reduces driver visibility to the rear of  
the vehicle due to spreader size and location. We  
recommend 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.

MAINTENANCE  
4. If bearings pass inspection be sure to thoroughly  
CAUTION  
grease them with a good quality multi-purpose  
grease. See Bearing Maintenance in this section.  
Disconnect electric power at spreader  
electrical wiring harness connection and tag  
out if required before servicing or performing  
maintenance.  
5. Verify 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.  
Cleaning  
6. Check the condition of the motor cap assembly  
seal. This seal is very important to the  
dependability of your unit. Replace the seal if  
needed.  
After every use, clean the spreader, but first disconnect  
the electrical plug located between the spreader and the  
truck. The spreader can be cleaned using tap water or  
a high pressure washer. Along handle brush can be  
used to aid cleaning.  
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.  
CAUTION  
• Do not operate a spreader in need of  
maintenance.  
8. Replace the motor cap assembly and locknuts.  
9. Verify vehicle stoplights and spreader center high  
mounted stoplight are working properly.  
• Before operating the spreader, reassemble  
any parts or hardware removed for cleaning  
or adjusting.  
Postseason Maintenance  
• Before operating the spreader, remove  
materials such as cleaning rags, brushes,  
and hand tools from the spreader.  
Before storing the unit for the off season, taking a few  
minutes to do the following will extend the service life of  
your spreader.  
• Empty and clean spreader after every use.  
Material can freeze or solidify causing unit to  
not work properly.  
1. Thoroughly clean the unit inside and out.  
Preseason Check  
2. Apply dielectric grease to all electrical connections  
to prevent corrosion.  
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.  
3. Grease the drive shaft bearings.  
4. Oil or paint all bare metal surfaces.  
Remove the motor cap assembly and inspect the  
following:  
5. Place the lid on the hopper body of the unit and  
secure the latch.  
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.  
6. Store the unit in an upright position; stabilize it with  
supports if necessary. If the unit is stored outdoors,  
cover the unit and place it on blocks to eliminate  
ground moisture.  
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 in this section. With  
the drive belt removed spin the drive shaft by hand.  
Any excess noise or roughness in either the top or  
the bottom bearing may indicate bearing failure.

MAINTENANCE  
Bearing and Set Screw Maintenance  
Disconnect the electrical plug between the spreader and  
the truck before performing any maintenance.  
1. Tighten all set screws shown after every 60 hours of  
use.  
2. Grease the top and bottom drive shaft bearings as  
shown. Due to the harsh environment of the bottom  
bearing it will require more care than the top  
bearing.

Battery wiring harness is damaged  
Unplug the spreader harness and tag  
out if required. Turn the spinner by  
hand. If the shaft will not turn freely by  
hand, check for any obstructions or  
frozen material. Clear all obstructions.  
Unplug the spreader harness and tag  
out if required. Remove the drive belt  
and spin the spinner by hand. If the  
shaft will not turn freely by hand, check  
for obstructions. If no obstructions  
exist, lubricate or replace the spinner  
bearings.  
Spinner, auger, or driveshaft is  
jammed or overloaded  
Spinner shaft bearings are damaged  
Unplug the spreader harness and tag  
out if required. Turn the spinner by  
hand. If the shaft will turn freely and  
the belt and pulleys are in working  
order, reconnect the spreader harness  
and 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.  
Spinner does not spin – The motor is  
not turning and 12V DC power is  
present at the red wire to red wire  
connection located near the rear of the

Check for 12V DC at the white wire to  
white wire connection near the back of  
the spreader control. If the control  
does not have power, the problem is in  
the control. Replace the control.  
Check for 12V DC at the white wire to  
white wire connection near 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 in the  
spreader wiring harness. Repair or  
replace the wiring harness as
