5/8‑11 locknuts.
1. Unbolt the screen retention bolts. Remove the
screens and set them aside.
2. If the material chute has been stored inside the
hopper, remove the chute and set it aside. Two or
more people are recommended for this step, as
the chute weighs more than 70 lb.
If the mounting holes are not directly over
the truck box supports, the truck bed must
be braced to the frame to prevent buckling or
deforming the truck bed. Accessory mounting
bars are available for installations that require
additional bracing. Contact your authorized dealer.
3. Lift the spreader by the four diagonal corner
rails, as shown, using slings or chains. Move the
spreader into the truck bed.
5. Connect the vehicle-side harness to the
hopper‑side harness.

4. Increase the engine speed to the desired RPM.
3. Turn the choke adjusting screw counterclockwise
five to seven turns.
4. Attempt to move the choke rod in the direction
of the choke adjusting screw. If the rod has no
movement, no adjustment is necessary.
5. Return the choke adjusting screw to its original
position or clockwise until it touches the choke
lever. If the choke rod has movement, bend
the engaging tab in the direction away from the
choke adjusting screw until there is no choke rod
movement.
6. In the event that bending the tab fails to remove
all choke rod movement, partially straighten out
the bend in the choke rod. This bend is near the
governor arm.
7. The choke adjusting screw, when properly
adjusted, stops excessive force from being
exerted on the choke actuator.

OPERATING THE SPREADER—HYDRAULIC MODELS
OPERATING THE CAB CONTROL
The hydraulic units operate from the truck-mounted
hydraulics and should be installed by an authorized
dealer. The dual-motor hydraulic-drive system allows
the operator to control the spinner and conveyor chain
independently.
1. Engage the hydraulic system with the spreader
lever in the "OFF" position.
2. To turn the spreader on, move the lever to the
"ON" position. The spinner and conveyor should
begin to turn.
The illustration shows a representative dual-motor
control valve available as an accessory through your
authorized dealer. Your control may look different;
refer to the operation instructions provided by the
installer of your specific system.
3. The spinner and auger speeds are independently
adjusted by rotating the adjustment knobs. The
knobs can be adjusted either during operation
or with lever in the "OFF" position. The speed
settings will be maintained when the lever is
placed in the "OFF" position.

SPREADING MATERIAL
SPREAD PATTERN ADJUSTMENT
• Spring pin in the left and center-left holes: Shutter
directs material to the left (driver's) side of vehicle.
The spread pattern and amount of material dispensed
depend on hopper drive speed, feed gate position,
and shutter setting:
• Spring pin in the center hole: Shutter directs
material evenly to both sides of vehicle.
• Spring pin in the right and center-right holes:
Shutter directs material to the right (curb) side
of vehicle.
• Decreasing hopper drive speed and/or gate
opening will decrease the amount of material
coming to the spinner.
• Increasing hopper drive speed and/or gate
opening will increase the amount of material
coming to the spinner.
Material flow is directed to left, right or center by the
movable shutter. Pull the spring pin located below the
spinner, rotate the spinner assembly, and reinsert the
pin in the appropriate hole.

• After every 50 hours of operation, grease the input
shaft bearing on the gear case and verify that the
oil level of the gear case is level with the fill hole.
CAUTION
Disconnect electric and/or hydraulic power
and tag out if required before servicing or
performing maintenance.
• Change the chain drive gear case oil once a
year. Drain the oil by removing the side cover of
the gear case. Refill with Mobil SHC 632, Exxon
SHP 320 or equivalent synthetic gear oil. Oil level
should be even with the bottom of the fill hole.
LUBRICATION
CAUTION
Over-greasing may cause seal damage. The
gear case must be filled to the oil-level plug
with Mobil SHC 632 or Exxon SHP 320 or
equivalent synthetic gear-type lubricant. Keep
the breather plug clean.
GEAR OIL SPECIFICATION
Use Mobil SHC 632 or Exxon SHP320 or equivalent.
• After every 10 hours of operation, grease the idler
bearings on the idler shaft, the flanged bearings
on the drive shaft, and the spinner shaft bearings.

DRIVE CHAIN AND SPINNER CHAIN
CONVEYOR PINTLE CHAIN TENSION
• At the beginning of each season, and once a month
during the season, verify that the drive sprocket
set screws and the clutch sprocket mounting bolts
are tight.
Periodically check the conveyor chain tension. The
spreader should be out of the vehicle for this procedure.
1. The chain should be visible through the chain
tension port. You should not be able to push the
chain up or down so it goes above or below the
hole. The chain should lift up 1"to 3" off the bottom
of the chain sill channel. If the slack is greater than
3" and the chain goes past the port, tighten the
chain as follows.
• Visually inspect the drive chain for wear. If it is
worn, replace the chain.
CAUTION
Overtightening the roller chains may damage
the bearings on the gear case and the engine.
Overtightening will also shorten the life of the
roller chain and of the sprockets.
2. Loosen the two bearing mounting bolts on each
side of the conveyor idle roller at the cab end of
the hopper.
• Maintain correct chain tension. Correct tension
allows for 1/4" of deflection midway between the
pulleys/sprockets.
3. Loosen the jam nut on one of the idler take‑up
bolts. Tighten the take-up bolt by turning it
clockwise while holding the jam nut. Repeat with
the opposite take-up bolt, tightening equally on
both passenger's side and driver's side until the
chain is in the middle of the chain tension port.
1/4"
Deflection
To increase engine chain tension: Loosen the four
bolts that secure the engine mount to the engine
base and pull the engine away from the clutch.
After correct tension is achieved, retighten the
engine mount bolts.

AFTER EACH USE
STORAGE
The spreader can be stored in truck position on blocks
or stands. Make sure the stands or supports are stable
and the ground beneath is compacted enough that it
will not shift over time.
CAUTION
DO NOT leave unused material in hopper.
Material can freeze or solidify, causing unit to
not work properly. Empty and clean after each
use.
1. Remove the chute from the hopper body. (See
"Removing the Chute.") Store the chute in a
horizontal position. It may be placed inside or on
top of the hopper if desired.
• Wash out the hopper and rinse off all external
surfaces.
• Clean out any trapped/frozen material from
between the pintle chain and the vehicle bed
surface.
2. Remove the hopper mounting bolts and tie-downs.
• Apply dielectric grease on all electrical
connections to prevent corrosion at the beginning
and end of the season and after each use.
3. Attach slings to the four corner lift points and,
using a hoist, lift the hopper out of the vehicle.
Move the spreader to the storage location with the
hoist or lower it onto blocks and use a forklift to
move it to a secure location.
• Lubricate all grease fittings with good-quality
multipurpose grease after every 10 hours of
operation.
4. The hopper body should be slightly tilted toward
the chute end to keep any rainwater from pooling
in the hopper.
5. Block the spreader so it is stable.
CAUTION
Before lifting, verify that the hopper is empty
of material. The lifting device must be able to
support the spreader's weight as shown in
the spreader specifications table.
At the End of Each Season or After
Extended Storage
• Wash out the hopper and rinse off all external
surfaces.
• Apply dielectric grease on all electrical
connections to prevent corrosion.
• Lubricate all grease fittings with good-quality
multipurpose grease.
• Clean the drive chain and spinner chain and
lubricate them with good-quality multipurpose
grease.
• Oil or paint any chipped or bare surfaces that are
not stainless steel.
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.
