STORAGE
4. Secure the spreader to the structure using chains
or straps to ensure that it cannot tip or fall.
The spreader can be stored on end (on its feet) for
storage; however, steps must be taken to properly
support it with blocks and secure it.
1. Back the truck near a wall, fence or other
permanent structure so that there is enough room
to remove the spreader but the spreader will be
against the structure when it is taken out of the
truck.
2. Remove the spreader from the truck following the
instructions in this manual.
3. Add blocks supporting the sides of the hopper
body and conveyor, as shown.

RECYCLE
When your spreader has performed its useful life,
many of its components can be recycled as steel.
Gear oil shall be disposed of according to local
regulations. Balance of parts made of plastic shall be
disposed of in customary manner.
• Wash out the hopper and rinse off all external
surfaces.
• Apply dielectric grease on all electrical
connections to prevent corrosion.
GEAR OIL SPECIFICATION
• Lubricate all grease fittings with good quality
multipurpose grease.
Use Mobil SHC 632 or Exxon SHP 320 or equivalent.
• Oil or paint all bare metal surfaces.
FUSE REPLACEMENT
See the Harness Wiring Diagram for fuse locations.
If a problem should occur and fuse replacement is
necessary, the replacement fuse must be of the same
type and amperage rating as the original. Installing a
fuse with a higher rating can damage the system and
could start a fire.
