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
fi
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
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" 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
or adjusting.
• Before operating the spreader, remove
materials such as cleaning rags, brushes
and hand tools from the spreader.
• Empty and clean spreader after every use.
Material can freeze or solidify, causing unit
to not work properly.
CAUTION
Disconnect electric power at spreader
electrical wiring harness connection and tag
out if required before servicing or performing
maintenance.
