Clearing a Clogged Discharge
Chute

WARNING

Hand contact with the rotating rotor blades inside
the discharge chute is the most common cause of
injury associated with machines. 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 the cleanout tool mounted on the
snowthrower, 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
machines or other safety information that you must know.

Rotating auger/impeller can cut off or 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, inspecting, troubleshooting, or
repairing the machine,

stop the engine, remove the key,

and wait for all moving parts to stop. Disconnect
the wire from the spark plug and keep it away from
the spark plug to prevent someone from accidentally
starting the engine.

Before

leaving the operating position, stop the engine,

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

To unclog the discharge chute, stay in the operating
position and release the left hand (traction) lever. While
running the auger/impeller, push down on the handles to

raise the front of the machine a few inches (centimeters)
off the pavement. Then lift the handles quickly to bump
the front of the machine on the pavement. Repeat if
necessary until a stream of snow comes out the discharge
chute.

If you cannot unclog the discharge chute by bumping
the front of the machine,

stop the engine, wait for

all moving parts to stop, and use the cleanout tool;
never use your hand.

If a shield, safety device, or decal is damaged, illegible, or
lost, repair or replace it before beginning operation.

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, remove the key, and
disconnect the wire from the spark plug. If major repairs
are ever needed, contact your 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.
