Installation Instructions
Mounting the Spreader onto the
Vehicle
1. Install the inverted “V” in the
spreader using the bolts, nuts, and
washers provided. See Figure 6.
2. Remove the tailgate from the
vehicle.
3. Lift the spreader by attaching the
lifting device to the slot on the
passenger side of the rear inside
brace.
4. Place the spreader on top of two
pieces of lumber so that the lumber
rests under the side gussets as
shown in Figure 7. NOTE: This will
help to remove any excess material
that accumulates under the
spreader.
5. Lift the spreader and place it in the
back of the vehicle so that it is
centered to the vehicle and the rails
of the spreader are 14” from the
rear of the truck.
6. Bolt the spreader to the vehicle
frame through side gussets and the
lumber.
7. Tie the spreader to the vehicle from
the tie-down eyes to the vehicles
anchor points.

Things to Know after Mounting the
Spreader
A. The tie-down straps are provided for
the purpose of securing the
spreader to the vehicle only and are
not to be used for any other
purpose. It is imperative that the
spreader be tied to the vehicle at all
times.
B. Be sure to verify with vehicles
manufacturer that the factory
installed anchor points are designed
for this application.
C. Periodically check to see if the
spreader mounting hardware is
securely tightened.
Mounting the Spinner/Chute
Assembly
1. Attach the Spinner/Chute Assembly
to the spreader using the four 3/8-
16 X 5/8” hex head bolts, lock
washers and nuts provided. Attach
the bolts so that the bolt head is
inside the chute assembly. Refer to
Figures 8-9. NOTE: Attach the bolts
loosely at this time.
2. Install the roller chain between the
sprocket mounted to the
Spinner/Chute Assembly and the
Gearbox Sprocket. Make sure both
sprockets are in-line with one
another. Tighten the gearbox
sprocket set screw. Install the roller
chain master link. See Figure 10.
Figure 8.
Figure 9.
Figure 10.

3. Adjust the tension of the roller chain
by loosening the Pillow Block
Bearings that are supporting the
Spinner Shaft and moving the shaft
either towards or away from the
Gearbox Sprocket. The correct chain
tension should allow a 5/16”
deflection in the chain midway
between both chain sprockets. See
Figures 11-12. NOTE: Be sure to
maintain the vertical alignment
between the Spinner Shaft and the
bearings before re-tightening the
hardware.
4. Install the chain guard using the
three ¼-20 X ¾” hex head bolts, lock
washers, and nuts.
5. Torque the 3/8-16x1-1/4” Pillow
Block Bolts to 236 Inch-Pounds (20
Foot-Pounds).
Figure 11.
Figure 12.
CAUTION
Do not over-tighten the chain
tension. This can cause damage to
the chain, shaft, bearings and
Gearbox.

Spreader Operation
NOTE: Before Starting the engine, follow
all safety precautions.
Control Panel Description
1. The “Spinner”switch is a three
position switch with the following
functions:
a. OFF Position: While the switch is
in this position and the engine is
running, the spreader feed chain
and the spinner disk will remain
non-operational.
b. ON Position: While the switch is
in this position and the engine is
running, the spreader feed chain
and the spinner disk will
dispense the ice control material
at the normal regulated rate.
c. BLAST Position: While the switch
is in this position and the engine
is running, the spreader feed
chain and the spinner disk will
dispense the ice control material
at a higher rate. NOTE: In order
to use this option, the switch
must be held in this position. It
cannot be toggled like the “ON”
or “OFF” options.
2. The “Start”switch is a three position
switch with the following functions:
a. OFF Position: While in this
position, 12 VDC power is shut
off to the spreader.
b. ON Position: While in this
position, 12 VDC power is turned
on to the spreader.
c. START Position: While in this
position, the engine speed will
increase.
3. The “Choke” switch is a two position
switch with the following functions:
a. CHOKE/FAST Position: While in
this position, the engine speed
will increase to help start the
engine.
b. IDLE Position: While in this
position, the engine speed will
decrease to release the choke.

Wire Harness Installation
Figure 14.
1. The Hot Wire (RED) can be
connected to either the fuse box or
directly to the battery.
2. The White Wire must be ground to
the chassis.
Figure 15.
3. Connect the Female Connector to
the Male Connector near the engine.
Starting the Engine
1. Verify that the Spinner switch and
the Start switch on the spreader
control unit are in the OFF position.
2. Now turn the Start switch to the ON
position.
3. Move the Choke switch to the IDLE
position and hold for approximately
two seconds.
4. Turn the Start switch to the START
position and hold.
5. While the engine is cranking, move
the throttle switch to the
CHOKE/FAST position.
6. Release the Choke switch when the
engine starts to fire.
7. Release the Start switch when the
engine turns over.
8. Now move the Choke switch to the
IDLE position for ½ to 1 second to
release the choke.
Stopping the Engine
1. To stop the engine, simply move the
Start switch to the off position.
Spinner Operation
1. Start the engine and adjust the
speed to slightly above IDLE.
2. Move the Spinner switch to the on
position.
3. Increase the engine RPM by moving
the Choke Switch towards the
CHOKE/FAST position.
4. It is recommended that the clutch
only be engaged at the lowest
possible speed without stopping the
engine. This will prevent premature
spinner chain failure and tension
loss.

Spinner/Chute Assembly
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
the spreader.
4. The gearbox is designed to only
accept torque from the input shaft.
CAUTION
Always follow the spreader
precautions in order to limit any
damage done to the spreader
CAUTION
DO NOT ATTEMPT TO FREE THE FEED
CHAIN BY USING A PIPE WRENCH OR
SIMILAR TOOL TO MOVE OR
DISLODGE THE CHAIN.
IF THE FEED CHAIN IS MOVED, THE
GEARS WITHIN THE GEAR CASE WILL
STRIP. THIS ACTION WILL VOID THE
WARRANTY.
