Operation
1. The spread pattern and the amount
of material dispensed depends on
the following:
a. Engine RPM
b. Feed Gate Position
c. Baffle Settings
2. Keep the following information in
mind:
a. Decreasing the RPM’s will
decrease the amount of material
transporting to the spinner.
b. Increasing the engine RPM’s will
increase the amount of material
transporting to the spinner.
c. The size of the feed gate opening
will determine the amount of
material transporting to the
spinner in relation to the
position of the gate.
Precautions
1. If the feed chain does not move
because of dense material or jams,
remove all material from the hopper
and free the chain.
2. If the material in the hopper freezes,
move the spreader into a warm area
to thaw.
3. To prevent the feed chain from
freezing, do not store the material in
