To stop the snowthrower, disengage the electric
clutch. Before leaving the seat, stop the engine, dis-
engage the electric clutch, set the parking brake,
remove the key, and wait for all moving parts to stop.
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.
WARNING
If auger does not start and stop when engag-
ing/disengaging electric clutch, see your autho-
rized dealer. Under no circumstances should you
attempt to defeat the safety system.
• 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 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.
WARNING
If the auger stalls or the chute plugs, DISENGAGE
THE ELECTRIC CLUTCH, STOP THE ENGINE AND
REMOVE THE KEY. SET THE PARKING BRAKE.
WAIT FOR MOVING PARTS TO STOP. Remove the
foreign object or clear the spout with a piece of
wood before restarting the engine. Never place
hands into auger housing or spout to clear
jammed object. Auger may rotate when object is
removed.
• If snow stops flowing freely from the spout, back
away until the snowthrower clears itself.
CAUTION
Always raise the snowthrower before turning or
backing up, to prevent damage to the unit.
