Clearing a Clogged Discharge
Chute

Hand contact with the rotating rotor blades inside the
discharge chute is the most common cause of injury
associated with snowthrowers. Never use your hand to
clean out the discharge chute.

To clear the chute:

Shut the engine off !

Wait 10 seconds to be sure the rotor blades have
stopped rotating.

Always use a clean-out tool, not your hands.

Maintenance and Storage

Check all fasteners at frequent intervals for proper
tightness to be sure the machine is in safe working
condition.

Never store the machine with fuel in the fuel tank
inside a building where ignition sources are present,
such as hot water heaters, space heaters, or clothes
dryers. Allow the engine to cool before storing in
any enclosure.

Always refer to the

Operator’s Manual

for important

details if the machine 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 rotor blades.

Toro Snowthrower Safety

The following list contains safety information specific
to Toro products or other safety information that you
must know.

Rotating rotor blades can injure fingers or
hands.

Stay behind the handles and away from the

discharge opening while operating the machine.

Keep your face, hands, feet, and any other part
of your body or clothing away from moving or
rotating parts.

Before adjusting, cleaning, repairing, and inspecting
the machine, and before unclogging the discharge
chute,

stop the engine, remove the key, and wait

for all moving parts to stop.

Before

leaving the operating position, stop the

engine, remove the ignition key, and wait for all
moving parts to stop.

If a shield, safety device, or decal is damaged,
illegible, or lost, repair or replace it before beginning
operation. Also, tighten any loose fasteners.

Do not

smoke while handling gasoline.

Do not

use the machine on a roof.

Do not touch the engine while it is running or soon
after it has stopped because the engine may be hot
enough to cause a burn.

Perform only those maintenance instructions
described in this manual. Before performing any
maintenance, service, or adjustment, stop the engine
and remove the key. If major repairs are ever needed,
contact an Authorized Service Dealer.

Do not change the governor settings on the engine.

When storing the machine for more than 30 days,
drain the fuel from the fuel tank to prevent a
potential hazard. Store fuel in an approved fuel
container. Remove the key from the ignition switch
before storing the machine.

Purchase only genuine Toro replacement parts and
accessories.
