Operating the Spreader
Model # SP-1575/SP-1875
SPREADER LOADING
WARNING – Do not overload vehicle. Use chart below to calculate weight of material. Weights of material are an average for dry
materials.
Material Weight Per Cubic Ft.
Rock Salt 80-90 lbs.
Sand/Salt Mix 95-120 lbs.
• Warning – Never leave material in hopper for long periods of time as salt is hygroscopic and will attract atmospheric moisture and harden up.
When spreading sand mix, a 1:1 ratio for Sand/Salt mix is recommended to prevent the material from freezing.
SPREADER OPERATION
• The Dual Variable Speed Controller has dual nger-tip dials for maximum performance, digital system status with warning protection and built-
in Vibrator Switch.
• To start, press power switch on controller and spreader will accelerate to speed set on spinner and auger dials.
• To stop, press power on controller to off position.
• Speed of Auger and Spinner may be adjusted separately to get desired ow and spread distance
• The Vibrator Switch is needed for dense material or to increase the ow to the Auger. This eliminates bridging of material in hopper.
• A Material Bafe has been installed in your spreader to stop ne material from free owing. If using dense or damp material, or if more ow is
desired, remove Material Bafe. However, it is recommended that the Material Bafe remain in place if using bulk salt.
• It is important that the Inverted Vee not be removed except when servicing.
• If there are any problems while operating the spreader, refer to Troubleshooting Guide.
SPREADING TIPS
• Spread ice melters with the storm to prevent unmanageable levels of ice.
• Never exceed 10 m.p.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.
• Calculate spread pattern when near vegetation.
LICENSE PLATE INSTALLATION (IF REQUIRED BY LOCAL LAWS)
You will need (2) 1/4-20 X 1/2” machine screws along with nylock type nuts
(not included with spreader)
Install license plate with hardware to mounting holes provided in
hopper apron (see illustration)

General Wiring Instructions
Model # SP-1575/SP-1875
Step 1: Take harness assembly and route from the rear of the vehicle to the front. Route harness along frame and attach to frame holes and
frame supports. It is not recommended to attach to fuel or brake lines for obvious reasons. Do not route close to exhaust system or engine, even
though Snowex uses high temperature wiring, it still could melt under extreme heat and short the spreader electrical system, as well as the
vehicle electrical system.
Step 2: Mount rear plug on bumper using supplied bolts, locate towards the center of the bumper to reduce the amount of debris the tires will
throw to the rear. Important: Apply a small amount of dielectric grease to the plug. Also try to mount so plug faces upward to help keep plugs
tightly sealed.
Step 3: Secure harness from the rear to the front using heavy duty ty-wraps or frame clips along the frame and lighter duty ty-wraps everywhere
else.
Step 4: Layout harness portion that connects to the battery along the re wall and fender well. Do not connect power leads to battery yet. Drill
a 3/4” hole in the re wall, or use existing access hole, for the control portion of the harness and route connector and harness through hole.
Be sure to check the area on the other side of the re wall to make sure you are not going to dri ll into the vehicle harness or a control module.
Generally you can drill on either side of the steering wheel for a good location.
Step 5: Connect harness to the back of the controller and mount to a suitable location. NOTE: You may want to contact customer before mounting
controller, some prefer not to have holes drilled into the dashboard. Ty-wrap loose controller harness and move to the engine compartment. Do
not mount close to any heater vents.
Step 6: Connect power leads to the battery: Red + Positive, Black – Negative, always connect to the primary battery if using a dual battery
system, secure loose loom to any other large or medium vehicle harness with medium duty ty-wraps; this will secure wiring harness.
Step 7: Push the ON/OFF button on the controller to check for power, when that has been conrmed turn power OFF. The electrical portion of the
installation is complete.
NOTE: If adding an inline fuse use a 60 amp slow blow (time delay) or a 60 amp relay.
