MOUNTING THE SPREADER Before Mounting the Spreader 1. Remove the drive cover and remove the small plastic bag from that area. 4. Secure the front of the mount assembly to the channel using hold-down bolts. Hand tighten. 2. Remove solid plug on gear case and replace with elbow and breather contained in the plastic bag. Hold-down Bolt Factory Installed Gearbox Plug Elbow and Breather NOTE: Apply a small amount of grease to the bolt thread periodically to ensure easy removal. In-Bed Mount 1.
MOUNTING THE SPREADER 9. Connect the spreader wiring harness to the vehicle wiring harness. 6. Position the tabs of the hopper assembly over the top of the mount assembly, and lower. Spreader Wiring Harness Tab Vehicle Wiring Harness 10. Verify vehicle stoplights and spreader center high mounted stoplight are working properly. 7. Allow the hopper assembly to lower into position. NOTE: Grease all electrical connections with dielectric grease.
MOUNTING THE SPREADER Under-Frame Mount 1. Install the secondary frame into the subframe. 3. Lift the hopper assembly using a hoist or two people, and tip slightly forward. Secondary Frame Subframe Pockets Mount Bars CAUTION CAUTION Visually align tabs into the secondary frame. Visually check Hitch Pin holes before assembly. Never use a finger to check alignment. 4. Position tabs of the hopper assembly over the top of the mount assembly, and lower. 2.
MOUNTING THE SPREADER 5. Insert a hold-down pin on each side and secure with hairpin cotter pin. Hairpin Cotter Pin Hold-down Pin CAUTION Both hold-down pins must be in place and secured with hairpin cotter pins. The hopper assembly may become unstable if the pins are not properly secure while the vehicle is in motion. Never use a finger to check alignment. 6. Connect the spreader wiring harness to the vehicle wiring harness.
OPERATING THE SPREADER Driving and Spreading on Snow and Ice Accessory Circuit The yellow wire in the vehicle harness is provided for accessory use of 12 Amps or less. CAUTION Drinking and then driving or spreading is very dangerous. Your reflex, perceptions, attentiveness and judgement can be affected by even a small amount of alcohol. You can have a serious or even fatal collision if you drive after drinking. Please do not drink, then drive or spread ice control materials.
OPERATING THE SPREADER Adjusting the Gates and the Deflector Spread pattern, pattern width, and the amount of material dispensed are dependent on the spinner speed, gate position, and deflector position. WARNING Before making any adjustments to the gate/ deflector settings, turn the spreader off. Wait for all conveyor or spinner movement to stop. Deflector Effect Driver side open. Passenger side open. Both sides open. June 15, 2003 10 Lit. No.
OPERATING THE SPREADER There are two control options. They include the Variable Speed (PWM) Control and the ON/OFF Control. The ON/ OFF switch operates as emergency stop when required. Adjusting the Spinner Speed The speed setting can be adjusted when the spreader is either on or off. Variable Speed (PWM) Control 5 4 1. Turn the speed dial clockwise. As the numbers on the speed dial increase, so will the speed. 6 7 3 8 2 START BLAST Blast/Maximum Speed 9 1 ON 2.

RECEIVER HITCH Safety Hitch Balls Select by gross trailer weight rating, coupler socket size, and mounting platform thickness and hole size. Hole must not exceed threaded shank diameter by more than 1/16 inch. Use lock washer. Tighten according to instructions. When tightened, shank must protrude beyond bottom of nut. Gross trailer weight rating and ball diameter are marked on balls. WARNING • Do not overload any part of your towing system. • Do not modify your hitch.
RECEIVER HITCH Tire Inflation Controlling Trailer Sway Check often. Follow tow vehicle and trailer manufacturer’s recommendations. Improper tire inflation can cause trailer sway. Turbulence from another vehicle, a wind gust, or a downgrade can cause sudden sway along with shift of the trailer’s load or a trailer tire blowout. If the trailer sways, it is the driver’s responsibility to assess the situation and take appropriate action. Below are the suggestions that may apply when assessing the situation.
MAINTENANCE Conveyor Belt Tension CAUTION Disconnect electric power before servicing or performing maintenance. To adjust the conveyor belt tension, please adhere to the following instructions. To keep your spreader running smoothly, observe the following recommendations: 1. Loosen the two bearing mounting bolts on each of the idler bearings. • Lubricate grease fittings after each use and at the end of each season. 2.
MAINTENANCE After each use At the End of Each Season (or extended storage) • Wash out hopper and rinse off all external surfaces. • Wash out hopper and rinse off all external surfaces. • Wash out the secondary frame slots in the underframe mount to prevent build-up of material. • Apply dielectric grease on all electrical connections to prevent corrosion. • Lubricate all grease fittings with a low temperature synthetic grease. • Oil or paint all bare metal surfaces.
