OPERATING TiPS
Discharge snow down wind whenever possible.
To help prevent snow from sticking to the snow thrower,
allow the snow thrower to reach outdoor temperature
before using it. A light coat of wax may also be applied
to the inside surface of the snow thrower housing and
discharge chute.
Use tire chains to improve traction.
Use rear wheel weights to improve traction.
Before the first snowfall, remove all stones, sticks and
other objects which could become hidden by the snow.
Permanent obstacles should be marked for visibility.
Overlap each pass slightly to assure complete snow
removal.
