Safe

Operation

Practices

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!

Your Responsibility

Restrict the use of this power machine to persons who read, understand and follow the warnings and instructions in this manual and on the machine.

DANGER: This machine was built to be operated according to the rules for safe operation 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 hands and feet and throwing objects. Failure to observe the following safety instructions could result in serious injury or death.

Training

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 old to operate this machine. Children 14 years old and over should read and understand the operation instructions and safety rules in this manual and should be trained and supervised by a parent.

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, helpers, 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.

1. 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/impeller.

2. 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.

3. 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.

4. Use a grounded three-wire extension cord and receptacle for all units with electric start engines.

5. Adjust collector housing height to clear gravel or crushed rock surfaces.

6. Disengage all control levers before starting the engine.

7. Never attempt to make any adjustments while engine is running, except where specifically recommended in the operator’s manual.

8. Let engine and machine adjust to outdoor temperature before starting to clear snow.

9. 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.

a. Use only an approved gasoline container. b. Extinguish all cigarettes, cigars, pipes and other sources

of ignition. c. Never fuel machine indoors. d. Never remove gas cap or add fuel while the engine is hot

or running. e. Allow engine to cool at least two minutes before refuel-

ing. f. Never over fill fuel tank. Fill tank to no more than ½ inch

expansion. g. Replace gasoline cap and tighten securely. h. If gasoline is spilled, wipe it off the engine and equip-

ment. Move machine to another area. Wait 5 minutes

before starting the engine. i. 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.). j. Allow machine to cool at least 5 minutes before storing.

Preparation

Operation

1. Do not put hands or feet near rotating parts, in the auger/impeller housing or chute assembly. Contact with the rotating parts can amputate hands and feet.

2. The auger/impeller 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.

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.

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.

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. Disengage power to the auger/impeller when transporting or not in use.

15. Never operate machine at high transport speeds on slippery surfaces. Look down and behind and use care when backing up.

16. If the machine should start to vibrate abnormally, stop the engine, disconnect the spark plug wire and ground it against the engine. Inspect thoroughly for damage. Repair any damage before starting and operating.

17. Disengage all control levers and stop engine before you leave the operating position (behind the handles). Wait until the auger/impeller comes to a complete stop before unclogging the chute assembly, making any adjustments, or inspections.

18. Never put your hand in the discharge or collector openings. Always use the clean-out tool provided to unclog the discharge opening. Do not unclog chute assembly while engine is running. Shut off engine and remain behind handles until all moving parts have stopped before unclogging.

19. Use only attachments and accessories approved by the manufacturer (e.g. wheel weights, tire chains, cabs etc.).

20. If situations occur which are not covered in this manual, use care and good judgment. Contact your dealer or call (800) 800-7310 for assistance and the name of your nearest servicing dealer..

Maintenance & Storage

1. Never tamper with safety devices. Check their proper operation regularly. Refer to the maintenance and adjustment sections of this manual.

2. Before cleaning, repairing, or inspecting machine disengage all control levers and stop the engine. Wait until the auger/impeller come to a complete stop. Disconnect the spark plug wire and ground against the engine to prevent unintended starting.

3. Check bolts and screws for proper tightness at frequent intervals to keep the machine in safe working condition. Also, visually inspect machine for any damage.

4. Do not change the engine governor setting or over-speed the engine. The governor controls the maximum safe operating speed of the engine.

5. Snow thrower shave plates and skid shoes are subject to wear and damage. For your safety protection, frequently check all components and replace with original equipment manufacturer’s (OEM) par ts only. “Use of parts which do not meet the original equipment specifications may lead to improper performance and compromise safety!”

6. Check controls periodically to verify they engage and disengage properly and adjust, if necessary. Refer to the adjustment section in this operator’s manual for instructions.

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

8. Observe proper disposal laws and regulations for gas, oil, etc. to protect the environment.

9. Prior to storing, run machine a few minutes to clear snow from machine and prevent freeze up of auger/impeller.

10. Never store the machine or fuel container inside where there is an open flame, spark or pilot light such as a water heater, furnace, clothes dryer etc.

11. Always refer to the operator’s manual for proper instructions on off-season storage.

Do not modify engine

To avoid serious injury or death, do not modify engine in any way. Tampering with the governor setting can lead to a runaway engine and cause it to operate at unsafe speeds. Never tamper with factory setting of engine governor.

Notice regarding Emissions

Engines which are certiﬁed to comply with California and federal EPA emission regulations for SORE (Small Off Road Equipment) are certiﬁed to operate on regular unleaded gasoline, and may include the following emission control systems: Engine Modiﬁcation (EM) and Three Way Catalyst (TWC) if so equipped.
