OPERATING THE SPREADER

Driving and Spreading on Snow and Ice

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.

Follow your vehicle owner’s manual instructions for driving in snow and ice conditions. Remember when you drive on snow or ice, your wheels will not get good traction. You cannot accelerate as quickly, turning is more difficult and you will need longer braking distance.

Wet and hard packed snow or ice offers the worst tire traction. It is very easy to lose control. You will have difficulty accelerating. If you do get moving, you may have poor steering and difficult braking which can cause you to slide out of control.

Here are some tips for driving in these conditions.

• Drive defensively.

• Do not drink, then drive or spread ice control materials

• Spread or drive only when you have good visibility for operating a vehicle.

• If you cannot see well due to snow or icy conditions, you will need to slow down and keep more space between you and other vehicles.

• Slow down, especially on higher speed roads. Your headlamps can light up only so much road ahead.

• If you are tired, pull off in a safe place and rest.

• Spreader size reduces driver visibility to the rear of the vehicle due to spreader size and location. We recommend OSHA compliant backup alarm for all governed employers.

• Keep your windshield and all glass on your vehicle clean to see around you.

• Dress properly for the weather. Wear layers of clothing, as you get warm you can take off layers.

Accessory Circuit

The yellow wire in the vehicle harness is provided for accessory use of 12 amps or less.
