SAFETY
BEFORE ATTEMPTING ANY PROCEDURE IN THIS
BOOK, READ AND UNDERSTAND ALL THE SAFETY
INFORMATION CONTAINED IN THIS SECTION. IN
ADDITION, ENSURE ALL INDIVIDUALS WORKING
WITH YOU ARE ALSO FAMILIAR WITH THESE
SAFETY PRECAUTIONS.
For your safety Warning and Information Decals have
been placed on this product to remind the operator
to take safety precautions. It is important that these
decals are in place and are legible before operation
begins. New decals can be obtained from Sno-Way or
your local dealer.
REMEMBER The careful operator is the best
operator. Most accidents are caused by human error.
Certain precautions must be observed to prevent the
possibility of injury to operator or bystanders and/or
damage to equipment.
NEVER exceed vehicle GVWR, GAWR or Vehicle Hitch
Tongue Weight Rating.
NEVER operate spreader when under the influence of
alcohol, drugs or other medications that could hamper
your judgement and reactions. An accident may result in
serious injury or death to other persons or yourself.
ALWAYS operate vehicle in a well-ventilated area. The
carbon monoxide in exhaust gas is highly toxic and can
cause serious injury or death.
NEVER allow hands, hair or clothing to get near any
moving parts such as fan blades, belts and pulleys. Never
wear neckties or loose clothing when working on the
vehicle or Spreader.
NEVER wear wrist watches, rings or other jewelry when
working on the vehicle or individual equipment. These
things can catch on moving parts or cause an electrical
short circuit that could result in serious personal injury.
ALWAYS wear safety goggles when working on the
vehicle to protect your eyes from battery acid, gasoline,
and dust or dirt from flying off of moving engine parts.
ALWAYS be aware of and avoid contact with hot
surfaces such as engine, radiator, and hoses.
ALWAYS wear safety glasses with side shields when
striking metal against metal! In addition, it is
recommended that a softer (non-chipable) metal material
be used to cushion the blow. Failure to heed could result
in serious injury to the eye(s) or other parts of the body.
NEVER allow children or unauthorized person to
operate this spreader.
NEVER exceed 45 m.p.h. when loaded spreader is
attached to vehicle. Braking distances may be increased
and handling characteristics may be impaired at speeds
above 45 m.p.h. It is strongly recommended to load the
spreader at the job site and to dispense all of the
materials at the job site. Transportation of a loaded
spreader causes the material to become impacted and
may cause spreader flow problems.
ALWAYS lock the vehicle when unattended to prevent
unauthorized operation.
ALWAYS check the job site for terrain hazards,
obstructions and people.
ALWAYS check surrounding area for hazardous
obstacles before operating this unit.
ALWAYS inspect the unit periodically for defects. Parts
that are broken, missing or plainly worn must be replaced
immediately. The unit, or any part of it should not be
altered without prior written approval of the manufacturer.
ALWAYS shut off the vehicle engine, place the
transmission in Park, turn the ignition switch to the “OFF”
position and firmly apply the parking brake of the vehicle
before attaching or detaching the spreader from the
vehicle or when making adjustments to the spreader
gates and/or deflectors.
ALWAYS make sure personnel are clear of area being
spread. Material is discharged from spreader at a high
rate of speed and could injure bystanders.
ALWAYS inspect bolts and pins whenever attaching or
detaching the spreader, and before traveling. Worn or
damaged components could result in the spreader
dropping to the pavement while driving, causing an
accident.
NEVER place fingers in mounting frame or mount lug
holes to check alignment when attaching spreader.
Sudden motion of the spreader frame could severely
injure a finger.
NEVER use material in the spreader containing twigs,
brush, plastics, cans or other trash. Foreign materials
could plug drive and discharge and damage unit.
NEVER use wet materials in the spreader. This unit is
not designed to handle wet materials. Use only dry free
flowing materials.
NEVER leave materials in hopper for long periods of
time. Remember salt is hygroscopic and will attract
enough atmospheric moisture to cause it to "cake".
NEVER work on the vehicle without having a fully
serviced fire extinguisher available. A 5 lb or larger CO2
or dry chemical unit specified for gasoline, chemical or
electrical fires, is recommended.
NEVER smoke while working on the vehicle. Gasoline
and battery acid vapors are extremely flammable and
explosive.
NEVER free up a jam or unclog spreader while it is
plugged in. Always turn off vehicle and unplug spreader
when working on it.
NEVER remove a spreader full of material, or even
partially filled with material, from the vehicle. Always
empty spreader prior to removal from the vehicle.
REMEMBER it is the owner’s responsibility for
communicating information on the safe use and
proper maintenance of this machine.

5. If an existing hole is not available, look for an area to
drill the hole that satisfies these conditions:
• Hole should be drilled on the same side of the vehicle
firewall (left or right) as the vehicle battery.
• DO NOT put a hole in such a spot that will force the
wiring harness, when installed, to interfere or be routed
behind accelerator pedal, brake pedal, clutch pedal,
parking brake or associated linkage.
• DO NOT drill any holes until a thorough visual
inspection is performed to determine that the area
around the hole to be drilled, on both sides of the firewall,
is clear of any obstacles such as brake lines, linkage or
vehicle wiring.
NOTE: If the hole has to be drilled through carpeting or
insulation, reverse the direction of the drill until the carpet
has been penetrated, remove the carpet from the hole,
then use the forward direction to continue drilling through
the firewall, this should prevent "running" in the carpet.
6. Using a twist drill or hole saw, as necessary, drill a hole
through the vehicle firewall.
7. Insert wiring harness into firewall.
8. Find a location to mount the Toggle Switch that the
wires harness can reach. The drilled hole must be 15/32"
in diameter and in a panel no thicker than 1/8" thick. Use
the nut with the Toggle Switch to fasten it into place.
9 Uncoil the Vehicle Power Harness. Determine a route
from SWS to the bumper of the vehicle, along the frame
rails, and through the vehicle engine compartment to the
battery. Make sure to leave enough harness length at the
back bumper to reach the SWS. Use the supplied Cable
Ties to route the harness.
10. Locate the red power wire within the loom of the
Vehicle Power Harness and insert it through the same
hole in the firewall as the Battery Power Harness. Then
route it to the Toggle Switch.
11. Cut off any excess wire that isn't needed to reach the
Toggle Switch on either harness. Then strip the ends of
the wire and crimp on the Female Terminals.
12. Push the Female Terminals onto the Toggle Switch.
13. Cut off any excess black wire that isn't needed to
reach the battery on the Vehicle Power Harness. Then
strip the end of the wire and crimp on the 3/8" Ring
Terminal.
14. Attach the Vehicle Power Harness black wire to the
Negative (-) terminal on the battery and re-connect the
negative battery terminal.
15. Remove the fuse holder cap from the Battery Power
Harness, install the 20A Fuse, and fasten the fuse holder
cap onto the connector.
16. Plug the SWS 30 to the installed harness. Determine
which direction is ON and OFF for the Toggle Switch,
then label it.
CAUTION
DO NOT drill any holes until a thorough visual
inspection is performed to determine that the
area around the hole to be drilled, on both sides
of the firewall, is clear of any obstacles such as
brake lines, linkage or vehicle wiring.
CAUTION
Keep wiring harness away from moving parts,
sharp edges and areas of extreme heat to avoid
electrical failure and fire.

Theory of Operation
The ON/OFF switch only has one speed. Turn the switch
ON and the pump motor turns on full spraying speed. Turn
the switch OFF and the motor turns off and the unit stops
spraying. Since the units spraying speed is not variable,
its best to only use the system when the spreader's auger
speed is at or near it's max.
On/Off Motor Controller Operation
The pump is protected by a 20 amp fuse installed in the
wiring system near the vehicle battery.
Start:
When the ON side of the switch is selected, current will be
directed to the SWS pump motor. When the OFF side of
the switch is selected, current to the system end.
IMPORTANT: If ignition switch is turned off at any
time during operation the pump will not stop
running. This can drain the battery power and
destroy the SWS pump if left running for hours.
Wiring Schematics
An On/Off Control system schematic diagram is located in
your SWS Installation & Owner’s Manual.
CAUTION
The controller input voltage must be a minimum
of 11 volts DC for proper operation. Be sure the
vehicle battery and alternator are in good
operating condition and adequate to provide 11
volts DC to the controller.
