Safety
Improper use or maintenance by the operator or owner
can result in injury. To reduce the potential for injury,
comply with the safety instructions in the traction unit
operator’s manual and always pay attention to the
safety alert
symbol, which means CAUTION,
WARNING, or DANGER—“personal safety
instruction.” Failure to comply with the instruction may
result in personal injury or death.
Danger
When the snowthrower is in operation, the
impeller and auger can be rotating and cut off or
injure hands and feet.
• Before adjusting, cleaning, repairing and
inspecting the snowthrower, and before
unclogging the discharge chute, stop the engine
and wait for all moving parts to stop. Remove the
key.
• Use a stick, not your hands, to remove an
obstruction from the discharge chute.
• Stay behind the handles and away from the
discharge opening while operating the
snowthrower.
• Keep face, hands, feet, and any other part of
your body or clothing away from concealed,
moving, or rotating parts.
The auger/impeller may pick up and throw stones,
toys, and other foreign objects, causing serious
personal injury to the operator or to bystanders.
• Keep the area to be cleared free of all objects
that could be picked up and thrown by the
auger/impeller.
• Keep all children and pets away from area of
operation.

General Snowthrower Safety
The following instructions have been adapted from the
ANSI/OPEI and ISO standards.
Preparation
• Thoroughly inspect the area where the equipment is to
be used and remove all doormats, sleds, boards, wires,
and other foreign objects.
• Do not operate the equipment without wearing adequate
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.
• 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
gravel drives, walks, or roads. Stay alert for hidden
hazards or traffic. Do not carry passengers.
• 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.
• Do not overload the machine capacity by attempting to
clear snow at too fast a rate.
• Never operate the machine at high transport speeds on
slippery surfaces. Look behind and use care when
moving in reverse.
• Never direct discharge at bystanders or allow anyone in
front of the unit.
• Disengage power to the auger/impeller when the
snowthrower is transported or not in use.
• Never operate the snowthrower without good visibility
or light.
Maintenance and Storage
• Check fasteners at frequent intervals for proper
tightness to be sure the equipment is in safe working
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.
Toro Snowthrower Safety
The following list contains safety information specific to
Toro products or other safety information that you must
know that is not included in the ANSI or ISO standards.
• The rotating auger/impeller or rotor blades can cut
off or injure fingers or hands. Stay in the operator’s
position and away from the discharge opening while
operating the snowthrower. Keep your face hands,
feet, and any other part of your body or clothing
away from concealed, moving, or rotating parts.
• Before adjusting, cleaning, repairing, and inspecting the
snowthrower, and before unclogging the discharge
chute, stop the engine, remove the key, and wait for
all moving parts to stop. Also, pull the wire(s) off of
the spark plug(s) and keep it away from the plug(s) to
prevent someone from accidentally starting the engine.
• Use a stick, not your hands to remove obstructions
from the discharge chute.
4
• Before leaving the operator’s position, stop the engine,
remove the key, and wait for all moving parts to stop.
• Do not wear loose fitting clothing that could possibly
get caught in moving parts.
• If a shield, safely device, or decal is damaged, illegible,
or lost, repair or replace it before beginning operation.
Also, tighten any loose fasteners.
• Do not use the snowthrower on a roof.
• Perform only those maintenance instructions described
in this manual. Before performing any maintenance,
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
Dealer.
• To ensure the best performance and safety, purchase
only genuine Toro replacement parts and accessories to
keep the Toro all Toro. Do not use “Will Fit”
replacement parts and accessories as they could
cause a safety hazard.

Adjusting the Lift Springs
The lift springs can be adjusted to control the amount of
power it takes to lift the snowthrower and the downward
force the snowthrower has while traveling over the ground.
If you change the downward snowthrower force, it will
directly affect the power needed to lift the snowthrower.
1. To increase the downward force, which will make it
harder to lift the snowthrower, loosen the 2 eyebolts and
nuts attached to the lift springs (Fig. 26).
2. To make it easier to lift the snowthrower, which will
decrease the downward force, tighten the 2 eyebolts and
nuts attached to the lift springs (Fig. 26).

Adjusting the Discharge Chute
Danger
When the snowthrower is in operation, the
impeller and auger can be rotating and cut off or
injure hands and feet.
• Before adjusting, cleaning, repairing and
inspecting the snowthrower, and before
unclogging the discharge chute, disengage the
PTO, stop the engine, remove the key, and wait
for all moving parts to stop.
• Use a stick, not your hands, to remove an
obstruction from the discharge chute.
• Stay away from the discharge and auger
openings while operating the snowthrower.
• Keep face, hands, feet, and any other part of
your body or clothing away from concealed,
moving, or rotating parts.
You can rotate the discharge chute 180 degrees side to side
by turning the crank handle (Fig. 30).
16
You can adjust the height and distance snow is thrown by
moving the chute deflector, on top of the discharge chute,
up and down (Fig. 30).

Tips for Throwing Snow
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 the wheels slip, shift into a lower gear to reduce forward
speed.
Run the snowthrower for a few minutes after clearing snow
so moving parts do not freeze. Engage the PTO to clear any
remaining snow from inside the housing.
Do not overload the snowthrower by clearing snow at too
fast a rate. If the engine slows down, reduce forward speed.
Always use full throttle (maximum engine speed) when
throwing snow.
In wet or slushy conditions, reduce clogging of the
discharge chute by maintaining maximum engine speed and
by not overloading the engine.
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 trying to operate frozen controls.
Free all controls and moving parts before operating.

Caution
If you leave the key in the ignition switch, someone could accidently start the engine and
seriously injure you or other bystanders.
Remove the key from the ignition and disconnect the wire from the spark plug before you do any
maintenance. Set the wire aside so that it does not accidentally contact the spark plug.
Greasing and Lubrication
Grease and oil the machine after every 25 operating hours
or once a year, whichever occurs first.
Grease Type: General-purpose grease.
Oil Type: SAE 10W or l0W30.

Replacing the Snowthrower
Belt
Once each year, examine the drive belt for signs of wear
and cracking. If any are found, purchase a belt from an
Authorized Service Dealer and replace it.
Note: The procedure below documents how to replace the
belt when the snowthrower is on the tractor, so you can
replace the belt in the case that it breaks. You can also
easily replace the belt when installing the snowthrower on
the tractor.
Removing Belt
1. Move the snowthrower to a level surface.
2. Disengage the PTO and set the parking brake.
3. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
4. Lift the snow thrower up to the transport position.
5. Remove the one end of the belt spring from the
snowthrower frame (Fig. 37).
6. Remove the belt from the clutch pulley and the
snowthrower pulleys (Fig. 37 and 38).
