General Operating Instructions
Snow Removal Suggestions
• Determine the best snow removal pattern before beginning.
• Wind direction is an important factor to consider.
Rotate the spout to discharge snow downwind.
• Plan the pattern so that you avoid throwing snow on cleared areas and on yourself as you are operating.
• When land contour permits, it is best to travel in the longest direction to minimize turning.
• In very deep or heavy snow, it may be necessary to make the first pass with snowthrower partially raised, backing up every few feet and lowering the snowthrower to clear the snow left on the surface.
Also, it may be necessary to slice off less than the full width of the auger or reduce ground speed.
• If snow stops flowing freely from the spout, back away until the snowthrower clears itself.
DANGER
If the auger stalls or the chute plugs, DISENGAGE
THE ELECTRIC CLUTCH, STOP THE ENGINE AND
REMOVE THE KEY. SET THE PARKING BRAKE.
