Safety Definitions
WARNING: The symbol at left
identifies a SAFETY WARNING
that indicates a potentially
hazardous situation that, if not
avoided, could result in death or
serious personal injury.
A
CAUTION: Indicates a situation that, if
not avoided, could result in damage to
product or property.
NOTE: Identifies tips, helpful hints, and
maintenance information the reader should
know.
Safety Precautions
Observe the following safety procedures before
and during the use of the spreader. By following
these rules and applying common sense, possible
personal injury and potential damage to the
machine may be avoided.
Form No. 80359
WARNING:
e Before working with the spreader, secure
all loose fitting clothing and unrestrained
hair.
e Before starting the spreader, check that all
personnel and equipment are clear of the
spreader and the spray area.
e Before operating the spreader, check that
all safety guards are in place.
e Keep hands, feet, and clothing away from
power-driven parts and the conveyor chain.
e Do not climb on or allow others to climb
on the spreader at any time while
operating.
CAUTION:
e Before operating the spreader, reassemble
any parts or hardware that were removed.
e Before operating the spreader, remove
materials such as cleaning rags, brushes,
and hand tools from the spreader.

NOTE: Periodically through the snow
season, verify the mounting devices are secure.
|. Remove the tailgate from the truck.
2. Lift the spreader. See appropriate instructions
below.
WARNING: Before lifting,
verify hopper is empty of material.
The lifting device must be able to
support the spreader's weight.
Regular Capacity: Lift spreader by hooking
the loop (Mild Steel) or hole (16-Gauge
Stainless Steel) located on rear cross channel
inside hopper.
NOTE: The loop or hole is located at the
approximate balance point of the spreader.
The balance point may vary with engine fluid
levels, battery, top screen, or residual material
in hopper. See Figures 3 and 4.

3. Before lowering the spreader, place lengths of
lumber (2"x4"x48" minimum) under the side
ribs. By elevating the spreader off of the
vehicle, it is easier to remove excess material
that accumulates under the spreader. See
Figure 6.

4. Center the spreader on the vehicle with the
end of the spreader sills 11" to the rear of the
nearest vertical obstruction (bumper, trailer
hitch, etc.).
5. Measure the distance from the front of the
truckbed to the sills and make a spacer to
place between the bed and the rails. See
Figures 7 and 8 for approximate size, shape,
and location of spacer.

INSTALLATION INSTRUCTIONS
Chute Assembly
1. Loosely attach the chute assembly using four
3/8" x 3/4" bolts, flat washers, lock washers,
and nuts with the heads of the bolts on the
inside of the chute. See Figure 9.
NOTE: High Capacity 31" Chute Assembly -
Remove access panel on back of chute housing
to aid installation.

2. Push the chute assembly toward the front of
the vehicle. DO NOT tighten the bolts at this
time.
3. Install the roller chain between the spinner
shaft sprocket and the gear case sprocket with
the master link. See Figure 10.

Chains
Check engine-to-electric clutch roller chain
tension. Correct tension allows 5/16" deflection
midway between the sprockets.
To increase chain tension: loosen the four (4)
engine mount-to-engine base bolts and pull the
engine away from the electric clutch. Re-tighten
bolts. See Figure 31.
Figure 31
CAUTION: Over-tightening the roller
chains may damage the bearings on the gear
case, the engine, and/or the spinner shaft.
Over-tightening will also shorten the life of
the roller chain and of the sprockets.
Check the conveyor chain tension. To check the
tension, measure in 20"-24" from the end of the
sills. Push up on the chain with your hand. The
conveyor chain should lift 1"-3" off the conveyor
chain guide or cross angles. See Figure 32.
Use the (2) 5/8" x 6" take-up bolts at the front of
the spreader to adjust conveyor chain tension.
Turn both bolts equal amounts to ensure the
tension ins equally distributed across both sides of
the conveyor chain.

INSTALLATION INSTRUCTIONS
a Hydraulic Unit Installation
Recommended sequence of installation is as
follows:
1. Pump (not available from DD).
2. [Install hydraulic reservoir.
3. Install cab control valve (optional).
4. Install hydraulic hoses (not available from
DD).
5. Fill hydraulic reservoir and check system.
Pump
Because of the wide range of possible instal-
lations of this hopper spreader, no pump is
supplied with this unit. If your truck does not
have a pump suitable to your application, one
may be purchased from a local truck equipment
supplier. This pump should have a GPM output (9
GPM at normal operative RPM) at 1,500 PSI and
1" NPT suction and pressure ports.
Hydraulic Reservoir Installation
Position the reservoir outlet as high, or higher
than, the pump inlet. Keep the hose distance as
short as possible. (Reservoir used should have a
capacity of 1-1/2 to 2 times the pump maximum
flow rate in gallons.)
Form No. 80359
Cab Control Valve Installation
1. With the seat fully forward, select a suitable
location to mount the cab control valve
allowing for the operator to adjust the control
and to turn it ON and OFF.
2. Check for clearance with ALL controls in the
cab.
3. Under the cab, check for interference with
transmission, etc.
4. Check to see that cab control valve location
does not interfere with entering or leaving
cab.
5. Fabricate a bracket to mount cab control valve
in selected location.
6. Insert a grommet into all holes drilled for this
installation.
7. Mount valve and plumb pump and motor to
valve. Plumb Port “T” to reservoir, Port “P”
to pressure side of pump, and Port “REG” of
the valve to Port “B” of the motor.
8. Check machine for proper rotation of drive
shafts and hydraulic leaks.
