Safe Operation Practices for Walk-Behind Snow Throwers

This snow thrower is capable of amputating hands and feet and throwing objects.

Failure to observe the following safety instructions could result in serious injury.

Look for this symbol to point out im por tant safety precautions. It means CAUTION!!! BE COME ALERT!!! YOUR SAFE TY IS IN VOLVED.

WARNING: Always disconnect spark plug wire and place it where it can not con tact plug in order to pre vent ac ci den tal start ing when setting up, trans port ing, ad just ing or making re pairs.

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, porch es or other such structures or buildings.

Training

1. Read, understand and follow all instructions on the machine and in the manual(s) before operating this unit. Be thoroughly familiar with the controls and the proper use of the equipment. Know how to stop the unit and disengage the controls quickly.

2. Never allow children to operate the equipment. Never allow adults to operate the equipment without proper instruction.

3. Keep the area of operation clear of all persons, particularly small children.

4. Exercise caution to avoid slipping or falling, especially when operating the snow thrower in reverse.

Preparation

1. Thoroughly inspect the area where the equipment is to be used and remove all doormats, sleds, boards, wires, and other foreign objects.

2. Disengage all clutches and shift into neutral before starting the engine (motor).

3. Do not operate the equipment without wearing adequate winter garments. Avoid loose ﬁ tting clothing that can get caught in moving parts. Wear footwear that will improve footing on slippery surfaces.

4. Handle fuel with care; it is highly ﬂ ammable (a) Use an approved fuel container. (b) Never add fuel to a running engine or hot en-

gine.

fuel tank indoors.

(d) Never ﬁ ll 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 ﬁ lling.

(e) 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.

WARNING: Snow throwers have ex posed 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: Mufﬂ er 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 con stit u ents, and certain vehicle com po nents contain or emit chem icals known to the State of Cal i for nia to cause can cer and birth defects or oth er re pro duc tive harm.

(f) 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-open device.

(g) Replace gasoline cap securely and wipe up spilled

fuel.

(h) If fuel is spilled on clothing, change clothing im-

mediately.

5. Use extension cords and receptacles as speciﬁ ed by the manufacturer for all units with electric drive motors or electric starting motors.

6. Adjust the collector housing height to clear gravel or crushed rock surface.

7. Never attempt to make any adjustments while the engine (motor) is running (except when speciﬁ cally recommended by manufacturer).

8. 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.

Operation

1. Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times.

2. Exercise extreme caution when operating on or crossing gravel drives, walks, or roads. Stay alert for hidden hazards or trafﬁ c.

3. After striking a foreign object, stop the engine (motor), remove the wire from the spark plug, disconnect the cord on electric motors, thoroughly inspect the snow thrower for any damage, and repair the damage before restarting and operating the snow thrower.

4. If the unit should start to vibrate abnormally, stop the engine (motor) and check immediately for the cause. Vibration is generally a warning of trouble.

5. Stop the engine (motor) whenever you leave the operating position, before unclogging the collector/impeller housing or discharge chute, and when making any

repairs, adjustments or inspections.

6. When cleaning, repairing or inspecting the snow thrower, stop the engine and make certain the collector/impeller and all moving parts have stopped. Disconnect the spark plug wire and keep the wire away from the plug to prevent someone from accidentally starting the engine.

7. Do not run the engine indoors, except when starting the engine and for transporting the snow thrower in or out of the building. Open the outside doors; exhaust fumes are dangerous.

8. Exercise extreme caution when operating on slopes.

9. Never operate the snow thrower without proper guards, and other safety protective devices in place and working.

10. Never direct the discharge toward people or areas where property damage can occur. Keep children and others away.

11. Do not overload the machine capacity by attempting to clear snow at too fast a rate.

12. Never operate the machine at high transport speeds on slippery surfaces. Look behind and use care when operating in reverse.

13. Disengage power to the collector/impeller when snow thrower is transported or not in use.

14. Use only attachments and accessories approved by the manufacturer of the snow thrower (such as wheel weights, counterweights, or cabs).

15. Never operate the snow thrower without good visibility or light. Always be sure of your footing, and keep a ﬁ rm hold on the handles. Walk; never run.

16. Never touch a hot engine or mufﬂ er.

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:

1. SHUT THE ENGINE OFF!

2. Wait 10 seconds to be sure the impeller blades have stopped rotating.

3. Always use a clean-out tool, not your hands.

Maintenance and Storage

1. Check shear bolts and other bolts at frequent intervals for proper tightness to be sure the equipment is in safe working condition.

2. 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.

3. Always refer to operator’s manual for important details if the snow thrower is to be stored for an extended period.

4. Maintain or replace safety and instruction labels, as necessary.

5. Run the machine a few minutes after throwing snow to prevent freeze-up of the collector/impeller.
