winter outer garments. Wear footwear that will improve
footing on slippery surfaces.
• Adjust the auger housing height to clear gravel or
crushed rock surface.
• Never attempt to make any adjustments while the
engine is running, except when specifically
recommended by Toro.
• Let engine and machine adjust to outdoor temperatures
before starting to clear snow.
Danger

Preparation
• Thoroughly inspect the area where the equipment is to
be used and remove all doormats, sleds, boards, wires,
and other foreign objects.
• The operation of any powered machine can result in
foreign objects being thrown into the eyes. Always wear
safety glasses or eye shields during operation or while
performing an adjustment or repair.
Operation
• Do not put hands or feet near or under rotating parts.
Keep clear of the discharge opening at all times.
• Exercise extreme caution when operating on or crossing

• After striking a foreign object, stop the engine, remove
the wire(s) from the spark plug(s), thoroughly inspect
the snowthrower for any damage, and repair the damage
before restarting and operating the snowthrower.
• If the unit should start to vibrate abnormally, stop the
engine and check immediately for the cause. Vibration
is generally a warning of trouble.
• Stop the engine whenever you leave the operating
position, before unclogging the auger/impeller housing
or discharge chute, and when making any repairs,
adjustments, or inspections.
• When cleaning, repairing, or inspecting, make certain
the auger/impeller and all moving parts have stopped.
Disconnect the spark plug wire(s) and keep the wire
away from the plug to prevent someone from
accidentally starting the engine.
• Do not clear snow across the face of slopes. Exercise
extreme caution when changing direction on slopes. Do
not attempt to clear steep slopes.
• Never operate the snowthrower without proper guards,
plates, or other safety protective devices in place.
• Never operate the snow thrower near glass enclosures,
automobiles, window wells, drop-offs, and the like
without proper adjustment of the snow discharge angle.
Keep children and pets away.

condition.
• Always refer to the operator’s manual for important
details if the snowthrower is to be stored for an
extended period.
• Maintain or replace safety and instruction labels, as
necessary.
• Run the machine a few minutes after throwing snow to
prevent freeze-up of the auger/impeller.

service, or adjustment, stop the engine, remove the key
and pull the wire(s) from the spark plug(s), keeping it
away from the plug(s) to prevent someone form
accidentally starting the engine. If major repairs are
ever needed, contact your Authorized Toro Service
