Safe Operation Practices for Snow Throwers

As Recommended By: American National Standards Institute.

IMPORTANT: Safety standards require operator

presence controls to minimize the risk of injury. Your snow thrower is equipped with such controls. Do not attempt to defeat the function of the operator presence control under any circumstances.

Training

1. 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.

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 and pets.

4. Exercise caution to avoid slipping or falling especially when operating 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 before starting the engine (motor).

3. Do not operate the equipment without wearing adequate winter outer garments. Wear footwear that will improve footing on slippery surfaces.

4. Handle fuel with care; it is highly flammable. a. Use an approved fuel container. b. Never remove fuel tank cap or add fuel to

a running engine (motor) or hot engine (motor).

c. Fill fuel tank outdoors with extreme care.

Never fill fuel tank indoors.

d. Replace fuel cap securely and wipe up

spilled fuel.

e. Never store fuel or snow thrower with fuel

in the tank inside of a building where fumes may reach an open flame or spark.

f. Check fuel supply before each use, allow-

ing space for expansion as the heat of the engine (motor) and/or sun can cause fuel to expand.

5. 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.

6. Adjust the snow thrower height to clear gravel or crushed rock surface.

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

8. Let engine (motor) and snow thrower adjust to outdoor temperatures before starting to clear snow.

9. 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.

To help prevent the possible freeze-up of the recoil starter and of the engine controls, proceed as follows after each snow removal job.

1. With the engine running, quickly pull the re- coil starter handle (12) three or four times with a continuous full arm stroke. This will produce a loud clattering sound that is not harmful to the engine or starter.

2. Stop the engine. Wipe all snow and moisture from the carburetor cover, control levers and cables. Also move the choke control (14) and recoil starter handle (12) several times.

How To Remove Snow or Debris From The Auger Housing

(Figure 6)

WARNING: Do not attempt to remove snow or debris that may become lodged in auger housing

without taking the following precautions.

1. Release the auger drive lever (5).

2. Remove the ignition key (8).

3. Disconnect the spark plug wire.

4. Do not place your hands in the auger hous- ing (4) or the discharge chute (3). Use a pry bar to remove any snow or debris.

Snow Throwing Tips

1. This snow thrower will propel itself forward when the handle is raised enough to cause the auger blades to contact the ground. The auger should stop when auger control bar is released. If it does not stop, see “How To Adjust The Auger Control Cable” in the adjustment section.

2. Most efficient snow throwing is accomplished when the snow is removed immediately after if falls.

3. For complete snow removal, slightly overlap each previous path.

4. Whenever possible, discharge the snow down wind.

5. The distance the snow will be discharged can be adjusted by moving the discharge chute deflector. Raise the deflector for more distance or lower the deflector for less distance.

6. In windy conditions, lower the chute deflector to direct the discharged snow close to the ground where it is less likely to blow into unwanted areas.

7. For safety and to prevent damage to the snow thrower, keep the area to be cleared free of stones, toys and other foreign objects.

8. Do not use the auger propelling feature when clearing gravel or crushed rock driveways. Move the handle down to slightly raise the auger.

9. The forward speed of the snow thrower is dependent on the depth and weight of the snow. Experience will establish the most effective method of using the snow thrower under different conditions.

10.After each snow throwing job, allow the engine to run for a few minutes. The snow and accumulated ice will melt off the engine.

11.Clean the snow thrower after each use.

12.Remove ice, snow and debris from the entire snow thrower. Flush with water to remove all salt or other chemicals. Wipe snow thrower dry.

Dry And Average Snow

1. Snow up to eight inches deep can be removed rapidly and easily by walking at a moderate rate. For snow or drifts of a greater depth,slow your pace to allow the discharge chute to dispose of the snow as rapidly as the auger receives the snow.

2. Plan to have the snow discharged in the direction the wind is blowing.

Wet Packed Snow

Move slowly into wet, packed snow. If the wet, packed snow causes the auger to slow down or the discharge chute begins to clog, back off and begin a series of short back and forth jabs into the snow. These short back and forth jabs, four to six inches, will “belch” the snow from the chute.

Snow Banks And Drifts

In snow of greater depth than the unit, use the same “jabbing” technique described above. Turn the discharge chute away from the snow bank. More time will be required to remove snow of this type than level snow.
