Operating Conditions

Do not use the snow blower when visibility is poor. Under conditions 
of poor visibility, there is a greater risk of striking an obstacle or 
causing injury. Adjust the snow discharge chute to avoid hitting 
passing bystanders or vehicles. Stay clear of the snow discharge 
chute while the engine is running.

Operator Responsibility

Know how to stop the snow blower quickly in case of emergency. 
Understand the use of all snow blower controls.
Never permit anyone to operate the snow blower without proper 
instruction. Do not let children operate the snow blower. If people or 
pets suddenly appear in front of the snow blower while it is in 
operation, immediately release the drive clutch lever to stop the snow 
blower and avoid possible injury from the rotating auger.
While operating the snow blower, hold the handle firmly, and walk, 
don’t run. Wear suitable winter boots that resist slipping.

Hot Exhaust

The muffler becomes very hot during operation and remains hot for a 
while after stopping the engine. Be careful not to touch the muffler 
while it is hot. Let the engine cool before transporting the snow blower 
or storing it indoors.
To prevent fire hazards, keep the snow blower at least 3 feet 
(1 meter) away from building walls and other equipment during 
operation. Do not place flammable objects close to the engine.

Carbon Monoxide Hazards 

Exhaust contains poisonous carbon monoxide, a colorless and 
odorless gas. Breathing carbon monoxide can cause loss of 
consciousness and may lead to death. 
For your safety, do not operate the engine in an enclosed or partially 
enclosed area such as a garage. Your snow blower’s exhaust 
contains poisonous carbon monoxide gas which can collect rapidly in 
an enclosed or partially enclosed area and cause illness or death.

Clearing a Clogged Discharge Chute

Never use your hands, even with gloves, to clear the discharge chute.
Stop the engine and wait for the auger to stop turning. Use a clean-out 
tool, like a wooden stick, to unclog the discharge chute.

Semi-Self Propel Operation

To propel the snow blower, tilt 
the handlebar forward (UP) 
slightly to allow the auger blades 
to contact the ground and 
provide propel assist. Tilt the 
handlebar back (DOWN) to slow 
or stop the propel assist.

Operating the 
Controls

Fuel Valve

The fuel valve opens and closes 
the fuel line leading from the fuel 
tank to the carburetor. Make 
sure that the fuel valve is 
positioned exactly at either the 
ON or OFF position. When the 
snow blower is not in use, 
always leave the fuel valve in the 
OFF position to reduce the 
possibility of fuel leakage.

Engine Switch 
(A, AM type)

The engine OFF-ON-OFF switch 
controls the ignition system. 

OFF — Stops the engine. 
ON — Starting and running.

Engine Key Switch 
(AS type)

The engine ON-OFF key switch 
controls the ignition system. 

OFF — Stops the engine. 
ON — Starting and running 
(using recoil or electric starter).

Electric Starter 
Button (AS type)

The starter button is used to 
operate the electric starter when 
an outdoor 3-prong extension 
cord (

page 9

) is plugged into the 

starter box.

Disconnect the extension cord 
after the engine starts.

 WARNING

Engine exhaust contains poisonous carbon monoxide 
gas that can build up to dangerous levels in an 
enclosed or partially enclosed area. 

Breathing carbon monoxide can cause 
unconsciousness and death.

Never run the snow blower in an enclosed or partially 
enclosed area.
