Installation Instructions
NOTE: The left and right end plates may, on
occasion, get bent through improper handling
during shipment or storage. If this should hap-
pen, square and true the left and right end plates
before installation.
1. Aligning the spreader:
A. Position the spreader with the truck such that
the auger drive is located on the right side of the
truck (passenger side).
B. Lift the spreader up and under the dump body
tailgate, positioning the spreader forward as close
as possible to the dump body. The tailgate of the
dump body should lay down horizontally over the
spreader.
C. Support the spreader solidly and securely when
positioning for mounting.
2. Attach mounting brackets (See hardware
installation drawing on page 2.)
A. Attach a quick detach plate, (Item 1) to both
sides of the spreader frame using hinge pins (Item
2) and a hairpin cotter pins (Item 5).
B. Position the (2) quick detach plates over the
dump body rub rails and flush with rear edge of
dump body.
C. Weld the (2) quick detach plates to the dump
body rub rails. Weld the plates continuously around
(3) sides of each plate. Do not weld along the edge
of the plates next to the attachment pin.

D. Align the pin brace (Item 4) on the dump body
using the iron brace (Item 3) for exact positioning.
For proper fit, hanger iron brace may require some
minor bending.
E. Weld the (2) pin braces (Item 4) to the dump
body sides, all around.
F. Attach the iron braces (Item 3) to the pin braces
on the sides of the dump body and the sides of the
spreader using (2) hairpin cotter pins (Item 5).
G. If there is a gap between the spreader and the
dump body, weld or bolt a steel strip to the forward
edge of the spreader to cover the gap.
H. If you have purchased the tailgate side shields
(purchased separately as P/N 924F0106), bolt or
weld them to the inside of the tailgate to prevent
material spillage at the ends of the spreader.

Hydraulic Installation Instructions
A. During assembly take precautions to keep all
hydraulic components as clean as possible.
B. Allow enough hose length to prevent kinking
and stretching of the hoses and to permit raising
the dump body. Support long hoses with wire ties
or clamps.
C. Protect hoses from wear caused by sliding and/
or vibration.
D. For proper rotation of auger and spinner motors,
hoses may be reversed.
Note: Use of a pipe joint sealant compatible with
hydraulic oil is recommended for all screw fittings.
E. Use swivel type hose ends to connect hoses to
flow valve. Damage to valve body may occur if the
fittings in flow valve are over tightened
F. To achieve a positive shutoff of the auger mo-
tor, the inlet flow must pass through the ball valve
(pre-mounted to the spreader) & the supplied hose
must connect the ball valve to the auger’s hydrau-
lic motor as shown in the figures on the bottom of
page 4. (Inspection of this hose is recommended to
ensure no damage has occurred during shipping)

Hydraulic Pump Diagram
Operating Instructions
1. Pre-start up.
A. Use high grade non foaming hydraulic oil to fill
reservoir about 3/4 full.
B. Position valve on/off lever to off.
C. Move auger and spinner knobs on the valve to
the open position.
D. Engage PTO and circulate hydraulic oil for sev-
eral minutes to warm up.
E. Move valve on/off lever to on.
F. Inspect hydraulic system for leaks.
G. Check auger and spinner to see if they are work-
ing properly.
H. Refill reservoir to 3/4 full.
I. Hydraulic system should now be ready for use.
2. Initial use of spreader
A. Shut off spinner and auger knobs and position
the on/off lever to on. Engage the PTO and allow
the hydraulic system to warm up.
B. Open the cover plate and secure vertically with
locking brackets.
C. Open dump body tailgate as wide as possible
from bottom without bearing against cover plate.
Set stop chains.
D. Position spinner assembly to the far left (drivers
side), tighten clamp. Determine placement of mate-
rial at various spinner and auger speeds by spread-
ing a small amount of material (Far left position
used to spread (3) three or (4) four lane highway
from right lane).
E. Position spinner assembly to the far right (pas-
senger side), tighten clamp. Determine placement
of material at various spinner and auger speeds
by spreading a small amount of material (Far right
position used to spread (4) four lane highway from
left lane).
F. Changing auger and spinner speeds on the valve
and placing spinner at various positions from left to
right will produce various spread patterns.
CAUTION
A. Be sure everyone is standing clear.
B. Be alert for anything that may require shutting
down the system.
C. Before working in or around spreader equip-
ment, be sure all hydraulic controls are moved to
off position.

3. Using the Auger Lock-out System
A. Shut off spinner and auger and position the
main hydraulics on/off lever to off.
B. Remove the lock-out pin, rotate the handle, and
insert the pin through the holes in the handle and
the bracket to prevent accidental engagement of
the hydraulics. (see illustration below)
C. The lower tray may now be opened for servicing
the auger.
D. After servicing, first close and lock the tray then
reverse the steps to move the handle and pin back
to their original positions. BE SURE TO REINSERT
THE LOCK-OUT PIN THROUGH THE HOLES IN
THE HANDLE AND THE BRACKET.
E. Turn the main hydraulics back on and the
spreader is ready for operation.
Recommended Maintenance
A. Warm up hydraulic system before using.
B. Keep the reservoir 3/4 full with high grade non-
foaming hydraulic oil.
C. Use precautions to keep contaminants from get-
ting in reservoir when filling.
D. Quick connects are a prime source of
contamination.
1. Clean quick connects before connecting or
disconnecting them.
2. Protect quick connects from contaminates at
all times.
E. Lubricate all bearings with suitable type grease
on a regular basis. More frequent lubrication is
recommended during periods of heavy use.
F. Lubricate the spinner hinge rod periodically.
G. Maintain the proper lubrication level in all gear-
boxes with SAE 90 gear lubricant.
H. When not in use, keep the spreader tray empty
to prevent freezing of material around auger in
extremely cold weather.
I. To extend the life of your spreader:
1. Hose down and clean after each use.
2. Repaint and/or oil after each season.
CAUTION
Position the valve on/off control lever in the off posi-
tion when the spreader is not in use or is removed. In
the event the valve on/off control lever is left in the on
position, a heat problem may occur as the pump contin-
ues to pump oil to the hydraulic valve. This could cause
a hose to burst spraying hot oil.
CAUTION
Before working in or around the auger area, the valve
control lever must be in the off position. Disengage PTO,
shut off engine, and follow the auger lock-out instruc-
tions. MAKE SURE THE LOCK-OUT PIN IS ALWAYS USED
IN BOTH THE ON AND OFF POSITIONS. After servicing
is complete, reverse the process to restore the spreader
function.
4. Miscellaneous
A. Valve setting changes may be made with truck
in motion.
B. By moving on/off lever to the off position, spin-
Auger ON
ner and auger may be stopped at the same time
without changing their valve settings.
C. Close cover plate flat over spreader trough and
lock in place for normal use of dump truck. Tailgate
may be opened from top or bottom.
D. When truck is used for extensive hauling the
spinner assembly should be removed.
E. If auger clogs, shut off spinner, open auger knob
valve and increase the engine speed. With the
engine at a higher speed, move the valve lever
from the on to the off positions rapidly; repeat as
needed. This action may unclog the auger. If this
action fails to free the auger, manual unclogging
will be required.
