CLEANING
After every use, clean the spreader, but rst
disconnect the electrical plug located between the
spreader and the truck. The spreader can be cleaned
using tap water or a high pressure washer. A long
handle brush can be used to aid cleaning.
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
rst 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
4. If bearings pass inspection, be sure to thoroughly
grease them with a low temperature synthetic
grease. See Bearing and Set Screw Maintenance
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
dependability of your 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 the vehicle stoplights are visible and
working properly.
POSTSEASON MAINTENANCE
Before storing the unit for the o season, taking a few
minutes to do the following will extend the service life
of your spreader.
1. Thoroughly clean the unit inside and out.
2. Apply dielectric grease to all electrical connections
to prevent corrosion.
3. Grease the drive shaft bearings.
4. Oil or paint all bare metal surfaces.
5. Place the lid on the hopper body of the unit and
secure the latch.
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.

maintenance.
Before operating the spreader, reassemble
any parts or hardware removed for cleaning

Before operating the spreader, remove
materials such as cleaning rags, brushes,
and hand tools from the spreader.
