Disengage all control levers before starting the engine.
Never attempt to make any adjustments while engine is running, except where specifically recommended in the operator's manual.
Let engine and machine adjust to outdoor temperature before starting to clear snow.

Safe Handling of Gasoline

To avoid personal injury or property damage use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Serious personal injury can occur when gasoline is spilled on yourself or your clothes which can ignite. Wash your skin and change clothes immediately.

Use only an approved gasoline container.
Extinguish all cigarettes, cigars, pipes and other sources of ignition.
Never fuel machine indoors.
Never remove gas cap or add fuel while the engine is hot or running.
Allow engine to cool at least two minutes before refueling.
Never over fill fuel tank. Fill tank to no more than ½ inch below bottom of filler neck to provide space for fuel expansion.
Replace gasoline cap and tighten securely.
If gasoline is spilled, wipe it off the engine and equipment. Move machine to another area. Wait 5 minutes before starting the engine.
Never store the machine or fuel container inside where there is an open flame, spark or pilot light (e.g. furnace, water heater, space heater, clothes dryer etc.).
Allow machine to cool at least 5 minutes before storing.
Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before filling.
If possible, remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment on a trailer with a portable container, rather than from a gasoline dispenser nozzle.
Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.

Operation

Do not put hands or feet near rotating parts, in the auger/ impeller housing or chute assembly. Contact with the rotating parts can amputate hands and feet.
The auger/impeller control lever is a safety device. Never bypass its operation. Doing so makes the machine unsafe and may cause personal injury.
The control levers must operate easily in both directions and automatically return to the disengaged position when released.
Never operate with a missing or damaged chute assembly. Keep all safety devices in place and working.
Never run an engine indoors or in a poorly ventilated area. Engine exhaust contains carbon monoxide, an odorless and deadly gas.
Do not operate machine while under the influence of alcohol or drugs.
Muffler and engine become hot and can cause a burn. Do not touch. Keep children away.
Exercise extreme caution when operating on or crossing gravel surfaces. Stay alert for hidden hazards or traffic.
Exercise caution when changing direction and while operating on slopes.
Plan your snow-throwing pattern to avoid discharge towards windows, walls, cars etc. Thus, avoiding possible property damage or personal injury caused by a ricochet.
Never direct discharge at children, bystanders and pets or allow anyone in front of the machine.
Do not overload machine capacity by attempting to clear snow at too fast of a rate.
Never operate this machine without good visibility or light. Always be sure of your footing and keep a firm hold on the handles. Walk, never run.
Disengage power to the auger/impeller when transporting or not in use.
Never operate machine at high transport speeds on slippery surfaces. Look down and behind and use care when backing up.
If the machine should start to vibrate abnormally, stop the engine, disconnect the spark plug wire and ground it against the engine. Inspect thoroughly for damage. Repair any damage before starting and operating.
Disengage all control levers and stop engine before you leave the operating position (behind the handles). Wait until the auger/impeller comes to a complete stop before unclogging the chute assembly, making any adjustments, or inspections.
Never put your hand in the discharge or collector openings. Always use the clean-out tool provided to unclog the discharge opening. Do not unclog chute assembly while engine is running. Shut off engine and remain behind handles until all moving parts have stopped before unclogging.
Use only attachments and accessories approved by the manufacturer (e.g. wheel weights, tire chains, cabs etc.).
When starting engine, pull cord slowly until resistance is felt, then pull rapidly. Rapid retraction of starter cord (kickback) will pull hand and arm toward engine faster than you can let go. Broken bones, fractures, bruises or sprains could result.
If situations occur which are not covered in this manual, use care and good judgment. Contact Customer Support for assistance and the name of your nearest servicing dealer.

Clearing a Clogged Discharge Chute

Hand contact with the rotating impeller inside the discharge chute is the most common cause of injury associated with snow throwers. 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 impeller blades have stopped rotating.
Always use a clean-out tool, not your hands.

Maintenance & Storage
