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

in the manual(s) before attempting to assemble and operate. Keep

this manual in a safe place for future and regular reference and for

ordering replacement parts.

2. Be familiar with all controls and their proper operation. Know how to

stop the machine and disengage them quickly.

3. Never allow children under 14 years of age to operate this machine.

Children 14 and over should read and understand the instructions

and safe operation practices in this manual and on the machine and

be trained and supervised by an adult.

4. Never allow adults to operate this machine without proper

instruction.

5. Thrown objects can cause serious personal injury. Plan your snow-

throwing pattern to avoid discharge of material toward roads,

bystanders and the like.

6. Keep bystanders, pets and children at least 75 feet from the machine

while it is in operation. Stop machine if anyone enters the area.

7. Exercise caution to avoid slipping or falling, especially when

operating in reverse.

Preparation

Thoroughly inspect the area where the equipment is to be used. Remove

all doormats, newspapers, sleds, boards, wires and other foreign objects,

which could be tripped over or thrown by the auger.

1. Always wear safety glasses or eye shields during operation and while

performing an adjustment or repair to protect your eyes. Thrown

objects which ricochet can cause serious injury to the eyes.

2. Do not operate without wearing adequate winter outer garments.

Do not wear jewelry, long scarves or other loose clothing, which

could become entangled in moving parts. Wear footwear which will

improve footing on slippery surfaces.

3. Use a grounded three-wire extension cord and receptacle for all

machines with electric start engines.

4. Adjust auger housing height to clear gravel or crushed rock surfaces.

5. Disengage all control levers before starting the engine.

6. Never attempt to make any adjustments while engine is running,

except where specifically recommended in the operator’s manual.

7. Let engine and machine adjust to outdoor temperature before

starting to clear snow.

Safe Handling of Gasoline

To avoid personal injury or property damage use extreme care in handling

gasoline. Gasoline is extremely flammable and the vapors are explosive.

Serious personal injury can occur when gasoline is spilled on yourself or your

clothes which can ignite. Wash your skin and change clothes immediately.

1. Use only an approved gasoline container.

2. Extinguish all cigarettes, cigars, pipes and other sources of ignition.

3. Never fuel machine indoors.

4. Never remove gas cap or add fuel while the engine is hot or running.

5. Allow engine to cool at least two minutes before refueling.

6. Never over fill fuel tank. Fill tank to no more than ½ inch below bottom

of filler neck to provide space for fuel expansion.

7. Replace gasoline cap and tighten securely.

8. If gasoline is spilled, wipe it off the engine and equipment. Move

machine to another area. Wait 5 minutes before starting the engine. If

fuel is spilled on clothing, change clothing immediately.

9. Never store the machine or fuel container inside where there is an

open flame, spark or pilot light (e.g. furnace, water heater, space heater,

clothes dryer etc.).

10. Allow machine to cool at least 5 minutes before storing.

11. 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.

12. If possible, 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.

13. Keep the nozzle in contact with the rim of the fuel tank or container

opening at all times until fueling is complete. Do not use a nozzle lock-

open device.

Operation

1. Do not put hands or feet near rotating parts, in the auger housing or

chute assembly. Contact with the rotating parts can amputate hands

and feet.

2. The auger control lever is a safety device. Never bypass its operation.

Doing so makes the machine unsafe and may cause personal injury.

3. The control levers must operate easily in both directions and

automatically return to the disengaged position when released.

4. Never operate with a missing or damaged chute assembly. Keep all

safety devices in place and working.

WARNING! This symbol points out important safety instructions which, if not followed, could endanger the personal safety and/or property

of yourself and others. Read and follow all instructions in this manual before attempting to operate this machine. Failure to comply with

these instructions may result in personal injury. When you see this symbol. HEED ITS WARNING!

CALIFORNIA PROPOSITION 65

WARNING! Engine Exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to State of

California to cause cancer and birth defects or other reproductive harm.

DANGER: This machine was built to be operated according to the safe operation practices in this manual. As with any type of power

equipment, carelessness or error on the part of the operator can result in serious injury. This machine is capable of amputating fingers,

hands, toes and feet and throwing foreign objects. Failure to observe the following safety instructions could result in serious injury or death.

Section 1 — important Safe operation practiceS

5. Never run an engine indoors or in a poorly ventilated area. Engine

exhaust contains carbon monoxide, an odorless and deadly gas.

6. Do not operate machine while under the influence of alcohol or

drugs.

7. Muffler and engine become hot and can cause a burn. Do not touch.

Keep children away.

8. Exercise extreme caution when operating on or crossing gravel

surfaces. Stay alert for hidden hazards or traffic.

9. Exercise caution when changing direction and while operating on

slopes. Do not operate on steep slopes.

10. Plan your snow-throwing pattern to avoid discharge towards

windows, walls, cars etc. Thus, avoiding possible property damage

or personal injury caused by a ricochet.

11. Never direct discharge at children, bystanders and pets or allow

anyone in front of the machine.

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

too fast of a rate.

13. Never operate this machine without good visibility or light. Always

be sure of your footing and keep a firm hold on the handles. Walk,

never run.

14. Release auger control lever to disengage power to the auger when

transporting or not clearing snow.

15. Never operate machine at high transport speeds on slippery

surfaces. Look down and behind and use care when backing up.
