• Remove snow as soon as possible after it falls. This
produces the best snow removal results.
• Adjust the skids to match the type of surface being
cleaned; refer to Adjusting Skids.
• The snowthrower is designed to clean snow down to
the contact surface, but there are times when the front
of the snowthrower may tend to ride up. If this
happens, reduce forward speed.
• Discharge snow downwind whenever possible, and
overlap each pass to ensure complete snow removal. If
wheels slip, reduce forward speed.
Tips for Throwing Snow
• Always use full throttle (maximum engine speed).
• If your traction unit has a speed selector, use the slow
position (turtle).
• If your traction unit has a flow divider, set it as
appropriate for the snow conditions (i.e., vary the
setting from 10 o’clock for heavy snow to 12 o’clock
for lighter snow).
• The discharge chute can be rotated 180° side to side.
The direction is controlled by turning the chute control
crank in the chute control bracket.
• The chute deflector, on top of the discharge chute, can
be moved up and down to control the height and
distance snow is thrown (Fig. 5).
• Run the snowthrower for a few minutes after clearing
snow so moving parts do not freeze.
• Do not overload the snowthrower by clearing snow at
too fast a rate. If the engine slows down, reduce
forward speed or adjust the flow divider (where
applicable) to supply more power to the snowthrower.
• In some snow and cold weather conditions, some
controls and moving parts may freeze. Therefore,
when any control becomes hard to operate, stop the
machine and wait for all moving parts to stop; then
check all parts for freeze up. Do not use excessive
force when trying to operate frozen controls. Free
all controls and moving parts before operating.
