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 
rst 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 
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.
