MOUNTING THE SPREADER Fixed Mount Spreader NOTE: The spreader shall be installed according to instructions supplied. Your local outlet is trained to provide this service and service your spreader with factory original parts. 1. Install the left and right top brackets to the truck bed rail with one 1/2" cap screw, one 1/2" flat washer and one 1/2" locknut. Attach the other hole in the top bracket to the bed rail with one 1/2" cap screw and one 1/2" locknut. WARN ING CAUT ION 2.
MOUNTING THE SPREADER 1. Fasten the left and right top brackets along with any shims to the truck bed rail with two 1/2" cap screws, two 1/2" flat washers and two 1/2" locknuts per bracket. Install the two 5/16" cap screws and locknuts to the side of the top brackets. SWING AWAY® Spreader 2.

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 Spreader Control Starting and Stopping the Motor There are two control options. They are the ON/OFF Control and the Variable Speed (PWM) Control. WARNING Before starting the spreader, the driver shall verify all bystanders are a minimum of 25 feet away from operating spreader. CAUTION If the unit is equipped with a SWING AWAY® mount. Do not operate the spreader or the vehicle without securing the hinge pin in the base plate. 1.
OPERATING THE SPREADER ON/OFF Control (Late Style) Stopping the Motor 1. Set the power switch to the OFF position to stop the motor. The power switch will remain in this position. The power switch OFF position operates as emergency stop when required. ON OFF BLAST NOTE: Always place the cover on the hopper to prevent moisture buildup. Do not let the spreader sit idle with material in the hopper for an extended period of time.
OPERATING THE SPREADER Variable Speed (PWM) Control Stopping the Motor with Variable Speed (PWM) Control 5 4 7 3 8 2 START BLAST 1. Set the power switch to the OFF position to stop the motor. The power switch will remain in this position. This is also the emergency stop position. 6 NOTE: Always place the cover on the hopper to prevent moisture buildup. Do not let the spreader sit idle with material in the hopper for an extended period of time.
REMOVING THE SPREADER NOTE: Empty the hopper before removing the spreader. CAUTION During removal or mounting, securely grip spreader to avoid dropping. Removing the SWING AWAY® Spreader NOTE: Empty the hopper before removing the spreader. 1. Unplug the spreader and stoplight (if equipped). 2. Remove the hitch pin from the latch side hinge pin. Removing the Fixed Mount Spreader 3. Remove the 1/4" cap screw and locknut from the hinged side hinge pin. 1. Unplug the spreader and stoplight (if equipped).
MAINTENANCE 4. If bearings pass inspection be sure to thoroughly grease them with a good quality multi-purpose grease. See Bearing Maintenance in this section. CAUTION Disconnect electric power at spreader electrical wiring harness connection and tag out if required before servicing or performing maintenance. 5. Verify all drive sprocket set screws are tight. Verify that all other fasteners are tight. Refer to the Torque Chart in the safety section of this manual. Cleaning 6.
MAINTENANCE Drive Belt Replacement Recycle Disconnect the electrical plug between the spreader and truck before drive belt replacement. When your spreader has performed its useful life, the majority of its components can be recycled as steel. Gear oil shall be disposed of according to local regulations. Balance of parts made of plastic shall be disposed of in customary manner. CAUTION Overtightening the belt may result in damage to the motor or bearings. 1. Remove the motor cap assembly. 2.
MAINTENANCE Bearing and Set Screw Maintenance Disconnect the electrical plug between the spreader and the truck before performing any maintenance. 1. Tighten all set screws shown after every 60 hours of use. 2. Grease the top and bottom drive shaft bearings as shown. Due to the harsh environment of the bottom bearing it will require more care than the top bearing. Top Bearing Set Screw Motor Pulley Set Screw Shaft Pulley Set Screw Top Bearing: Grease after every 60 hours of use.
