LOADING
4. With the occupants in the vehicle for normal
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 foot (lb/ft3) of the
desired material. Divide the weight into the
payload to determine the maximum volume of
material that can be carried.
7. Compare the maximum volume to determine the
maximum height of the material in the spreader.
8. Fill the hopper with material to the calculated level.

Lit. No. 70691, Rev. 03 13 January 15, 2023
OPERATING THE SPREADER
SPREADING TIPS
• Spread ice melters with the storm to prevent
unmanageable levels of ice.
• Never exceed 10 mph (16 km/h) when spreading.
• For a wider pass, increase spinner speed.
• For a heavier pass, drive slower or increase
auger speed.
• Never operate spreader near pedestrians or pets.
• Calculate spread pattern when near vegetation.
NOTE: The spinner motor is not designed for
continuous duty. Allow the motor to cool between
long cycle times.
The application rate, which is the amount of material
spread on a given area, depends on three variables:
vehicle speed, spinner speed, and auger speed.
For consistency in spreading results, it is best to drive at
a constant speed.
The spinner speed changes the spread width. This
determines how much area the same material fed by the
auger will cover.
Auger speed changes how much material is fed to the
spinner. Changing this rate will change the amount of
material being spread in the same area.
Wider spread patterns will spread the same material over
a larger area, so the application rate will be decreased
unless the auger speed is increased, or you drive
slower. A narrower spread pattern requires the opposite
action—a slower auger speed or driving faster.
To maintain the application rate with a wider spread
pattern, increase the auger speed, drive slower, or
spread the area twice.
To maintain the application rate with a narrower spread
pattern, decrease the auger speed or drive faster.

OPERATING THE SPREADER
Adjustable Baffles
ADJUSTABLE MATERIAL BAFFLES
The Precision Pro spreader is equipped with
adjustable material ba󰀪es inside the hopper. These
ba󰀪es restrict the ow of salt to the auger. Leave
these ba󰀪es at the factory setting until you have
run some material through the spreader at di󰀨erent
combinations of auger and spinner speeds. The
ba󰀪es may need to be adjusted when changing to a
di󰀨erent spreading material.
Use a 1/2" wrench for the fasteners holding the ba󰀪es
in place. Loosen the bolt to move the ba󰀪e.

Lit. No. 70691, Rev. 03 15 January 15, 2023
OPERATING THE SPREADER
ADJUSTABLE SPINNER
The spreader is equipped with an adjustable spinner to assist in more precise material application. The spinner
plate gives the operator control of whether the material spreads to the right, left, or is centered. Before operating
the spreader, spread some material in a clear area where the spread pattern can be easily observed to see
how it changes with n adjustment. Use the instructions below as a guide to get the desired spread pattern. The
position of the ns may need to be changed when using di󰀨erent materials or spinner speeds.
When looking down at the spinner, moving the fins
clockwise will adjust the spread pattern toward
the left side of the spreader.
When the fins are in the center adjustment position,
the spread pattern will be centered (with most materials).
When looking down at the spinner, moving the fins
counterclockwise will adjust the spread pattern
toward the right side of the spreader.

Lit. No. 70691, Rev. 03 16 January 15, 2023
salt removal product or spraying your spreader with
a cleaning solution before rinsing. Rinse all cleaning
solutions o󰀨 thoroughly with water.
Sweep puddles of water from surfaces of the
spreader. Make sure to remove water from the bottom
of the hopper so the auger isn't frozen when the
spreader is used again.
When done cleaning, grease the bearings and put
dielectric grease on the plugs. Spray metal parts with
a corrosion prevention product or a light oil. Avoid
getting oil on the plastic, which will cause the plastic to
degrade.
CORROSION PREVENTION
Corrosion/rusting is a chemical reaction caused by the
presence of moisture, salt, and metal. Preventing any
one of these ingredients from coming in contact with
any other ingredient will prevent corrosion.
Storing the spreader indoors, cleaning the spreader
after each use, lubricating bearings, and spraying
oil on the metal will limit moisture coming into
contact with metal and salt. Although it is easier to
prevent contact with salt and exposed metal, using a
water-displacing oil (e.g., WD-40) may be useful.
Cleaning the spreader and rinsing it thoroughly after
each use will help to prevent corrosion by removing
the salt. Drying the spreader after cleaning will also
help. A backpack blower can dry the spreader very
well.
Rocks and debris thrown up by tires of the vehicle are
likely to chip paint or create small scratches that could
rust. Exposed metal can be prevented by spraying a
light oil on metal parts after each washing. This will
also create a barrier between the spreader and the
salt dust that will stick to the spreader frame, making it
easier to clean.
By cleaning and drying your spreader after each use
and spraying metal parts with a light oil after each
cleaning, you will be able to prevent most corrosion.
LUBRICATION
To keep your spreader running smoothly, lubricate the
grease ttings after each use and at the end of each
season.
MAINTENANCE
AFTER FIRST USE
Tighten all mounting fasteners.
CLEANING
To protect your Precision Pro spreader from corrosion,
and to increase its useful life, clean it after each storm.
By cleaning after each storm, salt build-up will be less
and the salt will be easier to remove. More importantly,
cleaning the unit can prevent corrosion.
AFTER EACH USE/STORM
NOTE: Do not spray water directly on the auger
bearing and seals.
Run the spreader to empty the hopper. Either back
up to the salt pile and spread into the pile, or put the
spinner on the lowest setting and the auger on the
highest setting until the hopper is empty. This process
will allow the material to come out faster and the
spinner will spread it in a smaller area. Clean up the
salt and place in a bucket or salt box.
Turn the spreader control OFF and unplug the
spreader before cleaning. Use water to rinse all of
the salt residue away. Pay special attention to tight
areas, enclosures, and hard-to-reach areas where
salt build-up is likely to be a problem. Rinse these
areas thoroughly. Avoid directly rinsing openings in
transmissions/motors, such as where a shaft might
come out of the housing. Use a car wash brush to
clean o󰀨 salt and dirt that is stuck. Consider using a
WARNING
Never remove the spreader with material in
the hopper.
CAUTION
Disconnect electric power at spreader electrical
wiring harness connection and tag out if required
before servicing or performing maintenance.
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.

Lit. No. 70691, Rev. 03 17 January 15, 2023
AT END OF EACH SEASON OR
EXTENDED STORAGE
• Apply dielectric grease on all electrical connections
to prevent corrosion at the beginning and end of
the season and each time the power plugs are
disconnected.
• Wash out the hopper and rinse o󰀨 all external
surfaces to prevent material build-up and corrosion.
• Paint or oil all bare metal surfaces at the end of the
season.
• Cover the spinner assembly when it is in the storage/
dump position for an extended period of time.
CAB CONTROL
Unplug the cab control from the control harness at
the end of the season or when the hopper is removed
from the vehicle.
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.
MAINTENANCE & ELECTRICAL COMPONENTS
WARNING
Never remove the spreader with material in
the hopper.
STORE THE SPREADER
How the spreader is stored can have a lot to do with
how long it will last and how well it performs. Store
the spreader in a sheltered area, preferably indoors.
If there is not space indoors, elevate the spreader on
wooden blocks outdoors and cover with a tarp. Before
putting the spreader away, perform a very thorough
cleaning, lubricate bearings, and spray oil on all metal
parts. Apply a protective plastic conditioner to the
hopper and lid to protect them from the elements.
Instead of oil on the frame, use a rust inhibitor spray
(read the label before using to make sure it is not
damaging to paint). Apply dielectric grease to all plugs
and connections prior to storing the spreader.
RECYCLE
When your spreader has performed its useful life,
many of its components can be recycled.
