WARNING: This machine is capable of amputating hands and feet and throwing objects. Read these safety

rules and follow them closely. Failure to obey these rules could result in loss of control of unit, severe

personal injury or death to you, or bystanders, or damage to property or equipment. The triangle      in text

signifies important cautions or warnings which must be followed.

Safe Operation Practices for Snowthrowers

IMPORTANT:

 Safety standards require operator presence controls

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

Training

1. Read, understand, and follow all instructions on the machine and in the

manuals 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 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 and shift into neutral 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.
Avoid loose fitting clothing that can get caught in moving parts.

4. Handle fuel with care; it is highly flammable.

a. Use an approved fuel container.
b. Never add fuel to a running engine or hot engine.
c. Fill fuel tank outdoors with extreme care. Never fill fuel tank

indoors. Replace fuel cap securely and wipe up spilled fuel.

d. 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.

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 on a trailer with a portable container, rather than from a

gasoline dispenser nozzle.

f.

Keep 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 immediately.

5. Use extension cords and receptacles as specified 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

surfaces.

7. Never attempt to make any adjustments while the engine (motor) is

running (except when specifically recommended by manufacturer).

8. Let engine (motor) and snowthrower 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 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 traffic.

3. After striking a foreign object, stop the engine (motor), disconnect the cord

on electric motors, thoroughly inspect snowthrower for any damage, and 
repair the damage before restarting and operating the snowthrower.

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, make certain the

collector/impeller and all moving parts have stopped. Disconnect the
spark plug wire and keep the wire away from the spark plug to prevent
accidental starting.

7. Do not run the engine indoors, except when starting the engine and for

transporting the snowthrower in or out of the building. Open the outside
doors; exhaust fumes are dangerous (containing CARBON
MONOXIDE, an ODORLESS and DEADLY GAS).

including speed shift lever,traction drive lever,auger drive lever ,the 
clutch drive lever, upper chut assembly and crank assembly.)

9. Never operate the snowthrower without proper guards, plates, or other

safety protective devices in place and working.

11. Never direct the discharge toward people or areas where property

damage can occur. Keep children and others away.

12. Do not overload the machine capacity by attempting to clear snow at too

fast a rate.

13. Never operate the machine at high transport speeds on slippery

surfaces. Look behind and use care when operating in reverse.

14. Disengage power to the collector/impeller when snowthrower is

transported or not in use.

15. Use only attachments and accessories approved by the manufacturer of

the snowthrower (such as tire chains, etc.).

16. Never operate the snowthrower without good visibility or light. Always be

sure of your footing and keep a firm hold on the handles. Walk, never
run.

17. Never touch a hot engine or muffler.

10. Never operate, the snowthrower near glass enclosures, automobiles,

window wells, drop-off, and the like without proper adjustment of the
snow discharge angle.

8.  Do not clear snow across the face of  slope.Exercise extreme caution 

when operating on slopes. Do not attempt to clear steep slopes.
