Preparation

• Thoroughly inspect the area where the machine is to be used and remove all doormats, sleds, boards, wires, and other foreign objects.
• Disengage all clutches and shift into neutral before starting the engine (motor).
• Do not operate the machine without wearing adequate winter garments. Avoid loose-fitting clothing that can get caught in moving parts.
• Wear footwear that will improve footing on slippery surfaces.
• Always wear safety glasses or eye shields during operation or while performing an adjustment or repair to protect eyes from foreign objects that may be thrown from the machine.
• Handle fuel with care; it is highly flammable.
• Use an approved fuel container.
• Never add fuel to a running engine or hot engine.
• Fill the fuel tank outdoors with extreme care. Never fill the fuel tank indoors.
• 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.
• When practical, 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 refueling is complete. Do not use a nozzle lock to open the device.
• Replace gasoline cap securely and wipe up spilled fuel.
• If fuel is spilled on clothing, change clothing immediately.
• Use extension cords and receptacles as specified by the manufacturer for all units with electric starting motors.
• Adjust the collector housing height to clear gravel or crushed rock surface.
• Never attempt to make any adjustments while the engine (motor) is running (except when specifically recommended by the manufacturer).

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 or walks. Stay alert for hidden hazards or operating near public roads.
• After striking a foreign object, stop the engine (motor), remove the wire from the spark plug, disconnect the cord on the electric motors, thoroughly inspect the snow thrower for any damage, and repair the damage before restarting and operating the snow thrower.
• If the machine should start to vibrate abnormally, stop the engine (motor) and check immediately for the cause. Vibration is generally a warning of trouble.
