Material densities are approximate and are based on dry,
loose material. It is the responsibility of the operator to
know the weight of the material to be spread and the vehicle
carrying capacity.
CAUTION
Read and adhere to manufacturer's
ice-control material package
labeling, including Material Safety
Data Sheet requirements.
CAUTION
Never use wet materials or materials with
foreign debris with any of these spreaders.
These units are designed to handle dry, clean,
free
fl

DETERMINING VEHICLE PAYLOAD
1. Install the hopper spreader and optional
equipment according to the instructions.
2. Install or attach any other equipment that will be
on the vehicle while the hopper spreader will be in
use (step bumper, trailer hitch, snowplows, etc.).
Fill gas tanks.
3. Obtain the Gross Vehicle Weight Rating (GVWR),
Front Gross Axle Weight Rating (FGAWR), and
Rear Gross Axle Weight Rating (RGAWR) from
the certi
fi
cation label located inside the driver-side
door jamb or door.
4. With the occupants in the truck for normal hopper
spreader operation, weigh the vehicle to obtain
gross vehicle weight (GVW).
5. Subtract the GVW from the GVWR to determine
the available material payload.
6. Obtain the weight per cubic yard (lb/yd³) of the
desired material. Divide the weight into the
payload to determine the maximum volume of
material that can be carried.
7. Fill the hopper with the calculated volume of
material. Reweigh the vehicle with occupants
and verify that the GVW is less than the vehicle's
ratings.
8. Repeat Steps 6 and 7 for each type of material.
WARNING
Overloading could result in an accident or
damage. Do not exceed GVWR or GAWR
ratings as found on the driver-side door
cornerpost of the vehicle. See Loading
section to determine maximum volumes of
spreading material.
