Buyers Municipal-Sized Hopper Spreaders are
intended for spreading abrasives and/or chemicals, primarily for ice and snow control. They are
intended for installation on truck chassis or dump
bodies with GVWR 26,000 lbs. Spreaders are
intended to be mounted on trucks with Cab To Axle/Tandem Dimension minimum of 84 inches.
IMPORTANT
The Cab to Axle/Tandem dimensions are only guidelines.
Consult federal, state and local weight laws and chassis
manufacturer’s ratings to ensure neither government weight
restrictions, nor GVWR and GAWRs are exceeded.

General Safety Precautions
WARNING
Observe the following Safety Precautions before,
during and after operating this spreader. By following these precautions and common sense, possible
injury to persons and potential damage to this
machine may be avoided.
1. Read this entire Owner’s Manual before operat
-
ing this spreader.
2. Read all safety decals on the spreader before
operating the spreader.
3. Check to make sure all safety guards are securely
mounted into place before operating your spreader.
4. Verify that all personnel are clear of the spreader
spray area before starting or operating this
spreader.
5. Keep all loose clothing, hair, jewelry and limbs
clear of the spreader before starting or operating
this spreader.
6. Do not over-load your vehicle beyond payload
limits.
7. Do not perform any service operation on the
spreader while it is running.
8. Do not climb on or into the spreader during
operation.
9. Do not ride on the spreader while the vehicle is
in motion.
10. Make sure the spreader is securely fastened to
the vehicle.
11. Do not operate a spreader that is in need of
maintenance or repair.
Center the spreader in the vehicle. Spreader sills
3.
must overhang 20” beyond the back end of the vehicle.
4. If the dump body is not flat, it is suggested that
the spreader be placed on two 1" x 6" hardwood
boards. This will evenly distribute the weight of
the loaded spreader on the entire cross channels.
5. The spreader may be secured to the vehicle by
using Tie-Down Kit Buyers part #3010548 (sold
separately).
6. Periodically check that the spreader mounting
hardware is securely tightened.
Chassis Mounting
1. Hardwood wear strips usually 1" x 3" (not furnished) must be fitted to the truck chassis.
2. The spreader should be positioned on the
wooden wear strips so hopper sills must overhang
20” beyond the back end of the vehicle.
3. In addition a distance of approximately 4"-6"
must be left between the truck cab and the front of
the hopper. This will help facilitate any future servicing of the conveyor chain.
4.
Qualified installer must fabricate suitable angles to
attach hopper cross members to track’s frame.
DO NOT weld mounting angles to the truck frame.
Doing so can cause fatigue cracking of the truck frame.

General Installation Instructions
Dump Body Mounting
1. Remove the tailgate from the vehicle if
applicable.
2. Lift the spreader using the (4) lifting loops in the
corners of the hopper.
WARNING
The lifting device must be adequately rated to lift
a payload equal to or greater than the spreader
weight. See page 1 for spreader weights. Empty the
spreader before lifting.

Chute Installation
1. Bolt chute to Hopper using provided hardware.
2. Chute heights can be adjusted by sliding lower
chute assembly up or down inside of upper chute
assembly. Adjustment slots are spaced by 3".
Secure lower chute assembly using all 4 carriage
bolts provided. Make sure all four bolts are used
for installation. To increase ground clearance
cut upper chute as shown and use lower slots in
bottom chute.
3. The spread pattern and the amount of material
dispensed will depend on the following factors:
• Auger speed.
• Spinner RPM.
• Baffle settings.
Below are illustrations that show the baffles effect
on the spread pattern as viewed from the top of the
spinner disk.

Installation Instructions – Hydraulic System
1. During assembly take precautions to keep all
hydraulic components as clean as possible.
2. 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.
3. Protect hoses from wear caused by sliding and/
or vibration.
4. For proper rotation of conveyor chain and
spinner motors, hoses may be reversed.
5. Note: Use of a pipe joint sealant compatible with
hydraulic oil is recommended for all screw fittings.
6. 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.
7. A 10 micron return line filter is recommended
to protect the pump, valve, and motors from wear
causing contamination.
