Safety Rules

IMPORTANT: This machine is capable of amputating hands and feet and throwing objects. Failure to observe the following safety instructions could result in serious injury or death.

• Look for this symbol ⚠️ to point out important safety precautions. It means CAUTION!!! BECOME ALERT!!! YOUR SAFETY IS INVOLVED.
• WARNING: Always disconnect spark plug wire and place it where it cannot contact plug in order to prevent accidental starting when setting up, transporting, adjusting or making repairs.
• WARNING: This snow thrower is for use on sidewalks, driveways and other ground level surfaces. Caution should be exercised while using on sloping surfaces. Do not use snow thrower on surfaces above ground level such as roofs of residences, garages, porches or other such structures or buildings.
• WARNING: Snow throwers have exposed rotating parts, which can cause severe injury from contact, or from material thrown from the discharge chute. Keep the area of operation clear of all persons, small children and pets at all times including startup.
• CAUTION: Muffler and other engine parts become extremely hot during operation and remain hot after engine has stopped. To avoid severe burns on contact, stay away from these areas.
• WARNING: Engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

TRAINING

• Read the operating and service instruction manual carefully. Be thoroughly familiar with the controls and the proper use of the equipment. Know how to stop the unit and disengage the controls quickly.
• Never allow children to operate the equipment. Never allow adults to operate the equipment without proper instruction.
• Keep the area of operation clear of all persons, particularly small children and pets.
• Exercise caution to avoid slipping or falling especially when operating in reverse.

PREPARATION

• Remove foreign objects. Thoroughly inspect the area where the equipment is to be used and remove all doormats, sleds, boards, wires, rocks & landscaping.
• Disengage all clutches before starting engine (motor).

General Operation Safety

• Do not operate the equipment without wearing adequate winter outer garments. Avoid loose, dangling clothing, such as scarves, which can get caught in rotating parts. Wear footwear that will improve footing on slippery surfaces.
• Handle fuel with care; it is highly flammable. Never smoke while refueling. Use an approved fuel container. Never remove fuel tank cap or add fuel to a running engine (motor) or hot engine (motor). Fill fuel tank outdoors with extreme care. Never fill fuel tank indoors. Replace fuel cap securely and wipe up spilled fuel. Never store fuel or snow thrower with fuel in the tank inside of a building where fumes may reach an open flame or spark.
• Check fuel supply before each use, allowing space for expansion as the heat of the engine (motor) and/or sun cause fuel to expand.
• STATIC ELECTRICITY HAZARD: 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 opening at all times, until refueling is complete. Do not use a nozzle lock-open device. If fuel is spilled on clothing, change clothing immediately.
• For all units with electric starting motors use electric starting extension cords certified CSA/UL. Use only with a receptacle that has been installed in accordance with local inspection authorities.
• If snow thrower must be operated over gravel surface, use extra caution and be sure skid plates are adjusted to lowest (highest scraper clearance) position.
• Never attempt to make any adjustments while the engine (motor) is running (except when specifically recommended by manufacturer). Let engine (motor) and snow thrower adjust to outdoor temperatures before starting to clear snow.
• 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 snow thrower.

Adding Gasoline (Fig. 17)

Fill fuel tank to the bottom of the filler neck; do not overfill. Use fresh, clean, regular unleaded gasoline (minimum 87 octane). Do not mix oil with gasoline. Purchase fuel in quantities usable within 30 days.

WARNING: Wipe off any spilled oil or fuel. Do not store, spill, or use gasoline near an open flame.

CAUTION: Alcohol blended fuels (gasohol) can attract moisture, leading to separation and acidic gas that can damage the fuel system. Empty the fuel system before storage of 30 days or longer. Use fresh fuel next season. See Storage Instructions for details.

Starting the Engine

• Ensure fuel shut-off valve is OPEN.
• COLD START: Insert safety ignition key (do not turn). Set throttle to FAST. Rotate choke to FULL. Push primer 4 times (if below 15°F) or 2 times (if between 15°F and 50°F). Priming is not needed above 50°F. Pull recoil starter handle quickly. Once engine starts, release handle and slowly move choke to OFF. Allow engine to warm up.
• WARM START: Follow cold start steps, keeping choke in OFF position. Do not push primer.

Before Stopping

Run the engine for a few minutes to dry off moisture. To prevent starter freeze-up, pull the recoil starter handle with rapid, full arm strokes three or four times while the engine is running.

IF RECOIL STARTER HAS FROZEN: Grasp handle, pull rope out as far as possible, then release to snap back. Repeat if necessary.

Snow Throwing Tips

• Operate with the engine at full throttle for best performance.
• Go slower in deep, freezing, or heavy wet snow. Use the drive speed control, not the throttle, to adjust speed.
• Remove snow immediately after it falls.
• Early morning is often best as snow is usually dry.
• Slightly overlap paths to ensure all snow is removed.
• Throw snow downwind when possible.
• Adjust skid plates for current snow conditions.
• For heavy snow, reduce clearing width by overlapping paths and moving slowly.
• Keep the engine clean and clear of snow for airflow and engine life.
• After use, run the engine for a few minutes to melt snow and ice off.
• Clean the snow thrower thoroughly after each use and wipe dry.

WARNING: Do not operate if weather conditions impair visibility. Throwing snow during a heavy, windy snowstorm can blind you and be hazardous.
