2. PREPARATION

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

• Disengage all clutches and shift into neutral before starting engine.

• Do not operate equipment without wearing adequate winter outer garments. Do not wear jewelry, long scarfs or other loose clothing which could become entangled in moving parts. Wear footwear which will improve footing on slippery surfaces.

• Before working with gasoline, extinguish all cigarettes and other sources of ignition. Check the fuel before starting the engine. Gasoline is an extremely flammable fuel. Do not fill the gasoline tank indoors, while the engine is running, or until engine has been allowed to cool at least two minutes. Replace gasoline cap securely and wipe off any spilled gasoline before starting the engine as it may cause a fire or explosion.

• Use a grounded three wire plug-in for all units with electric drive motors or electric starting motors.

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

• Never attempt to make any adjustments while engine is running (except where specifically recommended by manufacturer).

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

• 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 in any direction.

3. OPERATION

• Do not put hands or feet near or under rotating parts. Keep clear of discharge opening and auger at all times.

• Exercise extreme caution when operating on or crossing gravel drives, walks, or roads. Stay alert for hidden hazards or traffic. Do not carry passengers.

• After striking a foreign object, stop the engine, remove wire from spark plug, and thoroughly inspect the snow thrower for any damage. Repair the damage before restarting and operating the snow thrower.

• If the snow thrower should start to vibrate abnormally, stop the engine and check immediately for the cause. Vibration is generally a warning of trouble.

• Stop engine whenever you leave the operating position, before unclogging the collector/impeller housing or discharge guide, and making any repairs, adjustments, or inspections. Never place your hand in the discharge or collector openings. Use a stick or wooden broom handle to unclog the discharge opening.

• Take all possible precautions when leaving the unit unattended. Disengage the collector/impeller, stop the engine, and remove the key.

• When cleaning, repairing, or inspecting, make certain collector/impeller and all moving parts have stopped. Disconnect spark plug wire and keep away from plug to prevent accidental starting.

• Do not run engine indoors, except when starting engine and transporting snow thrower in or out of building. Open doors. Exhaust fumes are dangerous.

• Do not clear snow across the face of slopes. Exercise extreme caution when changing direction on slopes. Do not attempt to clear steep slopes.

• Never operate snow thrower without guards, plates, or other safety protection devices in place.

• Never operate snow thrower near glass enclosure, automobiles, window wells, drop off, etc., without proper adjustments of snow thrower discharge angle. Keep children and pets away.

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

• Never operate the machine at high transport speeds on slippery surfaces. Look behind and use care when backing.

• Never direct discharge at bystanders or allow anyone in front of unit.

• Disengage power to collector/impeller when transporting or not in use.

• Use only attachments and accessories approved by the manufacturer of snow thrower (such as wheel weights, counter weights, cabs, etc.).

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

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

4. MAINTENANCE AND STORAGE

• Check shear bolts, engine mounting bolts, etc., at frequent intervals for proper tightness to be sure equipment is in safe working condition.

• Never store the machine with fuel in the fuel tank inside a building where ignition sources are present, such as hot water and space heaters, clothes dryers, and the like. Allow engine to cool before storing in any enclosure.

• Always refer to operator's manual instructions for important details if snow thrower is to be stored for an extended period.

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

• Check clutch controls periodically to verify they engage and disengage properly and readjust if necessary. Refer to operator's manual for adjustment instructions.

With engine running, pull starter rope with a rapid, continuous full arm stroke three or four times. Pulling the starter rope will produce a loud clattering sound, which is not harmful to the engine or starter.

3. To stop engine, remove the ignition key. Do not turn key. Disconnect the spark plug wire from the spark plug to prevent accidental starting while equipment is unattended.

NOTE: Do not lose ignition key. Keep it in a safe

place. Engine will not start without the ignition key.

4. Wipe all snow and moisture from the carburetor cover in the area of the control levers. Also, move control levers back and forth several times. Leave throttle control lever in the STOP or OFF position. Leave choke control in the FULL choke position.

TO ENGAGE DRIVE/AUGER

1. With the engine running near top speed, move shift lever into one of the FORWARD or REVERSE positions. Select a speed appropriate for the snow conditions that exist. Use the slower speeds until you are familiar with the operation of the snow thrower.

2. Squeeze the left hand auger drive clutch to engage auger.

3. While the left hand auger drive clutch is engaged, engage the right hand traction drive clutch.

NOTE: NEVER move shift lever without first

releasing the drive clutch.

TIRE CHAINS (OPTIONAL):

WARNING: Temperature of muffler and surrounding areas may exceed 150 Avoid these areas.

• For most efficient snow removal, remove snow immediately after it falls.

• Discharge snow downwind whenever possible. Slightly overlap each previous swath.

• Set the skid shoes 1/4" below the scraper bar for normal usage. The skid shoes may be adjusted upward for hard-packed snow. Adjust downward when using on gravel or crushed rock.

• Be certain to follow the precautions listed under ‘‘To Stop Engine’’ in previous column to prevent possible freeze-up.

• Clean the snow thrower thoroughly after each use.

SECTION 8: ADJUSTMENTS

WARNING: Never attempt to clean

chute or make any adjustments while engine is running.

ADJUSTING CHUTE

You can control the distance that snow is thrown by adjusting the angle of the chute assembly. The sharper the angle, the shorter the distance snow is thrown.

1. To adjust the chute, loosen the hand knob. See Figure 25.

2. Pivot the top of the chute assembly to the position desired.

Hand Knob

Figure 25

ADJUSTING SKID SHOE

The space between the shave plate and the ground can be adjusted by adjusting the skid shoe. Slide the skid shoe upwards and lower the housing to remove snow close to the ground. Slide skid shoe downwards and raise the housing to remove snow from uneven ground like gravel. For more details, refer to Adjusting the Skid Shoes in section 5.

ADJUSTING TRACTION DRIVE CLUTCH

Refer to the Final Adjustments section on page 10 for instructions to adjust the traction drive clutch. If you are not sure whether you have been able to adjust the traction drive clutch properly, check as follows.

1. Drain the gasoline from the snow thrower or put a plastic film under the gas cap if the snow thrower has already been operated. Tip the snow thrower forward onto the auger housing.

2. Remove the frame cover underneath the snow thrower by removing the six self-tapping screws.

3. With the traction drive clutch released, check if there is clearance between the friction wheel and the drive plate in all positions of the shift lever. For correct adjustment there has to be enough clearance.

4. With the traction drive clutch engaged, check if the friction wheel is contacting the drive plate. See Figure 26.

5. If adjustment is necessary, loosen the jam nut

in Axle

on the traction drive cable, and thread cable in or out as necessary.

6. Tighten the jam nut to secure the cable when correct adjustment is reached. Reassemble the frame cover with six self-tapping screws.

made to the engine while the engine is running (e.g. carburetor), keep clear of all moving parts. Be careful of heated surfaces and muffler.

Minor carburetor adjustment may be required to compensate for differences in fuel, temperature, altitude and load. Refer to the separate engine manual packed with your unit for carburetor adjustment information.

If any adjustments are

DRIVE WHEELS

The wheels may be adjusted for two different methods of operation. The adjustment is made by placing the klick pins in one of two different holes on the right side of the unit. See Figure 27.

1. One Wheel Driving—Place klick pin in the outside axle hole on the right side. This position gives power drive to the left wheel only, making the unit easier to maneuver.

2. Both Wheels Driving—Place klick pin in the hole in the hub next to the rim on the right side. This position is good for heavy snow as there is power drive in both wheels.

LIMITED

WARRANTY

For TWO YEARS from the date of retail purchase within the United States of America, its possessions and territories, the manufacturer will, at its option, repair or replace, for the original purchaser, free of charge, any part or parts found to be defective in material or workmanship. This warranty covers units which have been operated and maintained in accordance with the operating instructions furnished with the unit, and which have not been subject to misuse, abuse, commercial use, neglect, accident, improper maintenance or alteration.

Normal wear parts or components thereof are subject to separate terms as noted below in the “No Fault Ninety Day Consumer Warranty” clause.

All normal wear part failures will be covered on this product for a period of 90 days regardless of cause. After 90 days, but within the two year period, normal wear parts failures will be covered ONLY IF caused by defects in material or workmanship of OTHER component parts. Normal wear parts are defined as batteries*, belts, blades, blade adapters, grass bags, rider deck wheels, seats, snow thrower skid shoes, shave plates and tires.

How to obtain service: Warranty service is available, with proof of purchase, through your local authorized service dealer. To locate the dealer in your area, please check the yellow pages or contact the Customer Service Department of the manufacturer, P. O. Box 368022, Cleveland, Ohio 44136-9722. Phone 1-800-800-7310. The return of a complete unit will not be accepted by the factory unless prior written permission has been extended by the service department of the manufacturer.

Transportation charges: Transportation charges for the movement of any power equipment unit or attachment are the responsibility of the purchaser.

Units exported out of the United States: The manufacturer does not extend any warranty for products sold or exported outside of the United

States of America, its possessions and territories, except those sold through the manufacturer’s authorized channels of export distribution.

Other Warranties:

1. The engine or component parts thereof carry separate warranties from their manufacturers. Please refer to the applicable manufacturer’s warranty on these items.

2. *Batteries are covered by a 90-day replacement warranty.

3. Log splitter pumps, valves and cylinders or component parts thereof are covered by a one year warranty.

4. All other warranties, express or implied, including any implied warranty of merchantability or fitness for a particular purpose, are hereby expressly disclaimed in their entirety.

5. The provisions as set forth in this warranty provide the sole and exclusive remedy of the manufacturer’s obligations arising from the sales of its products. The manufacturer will not be liable for incidental or consequential loss or damage.

How state law relates to this warranty: This limited warranty gives you specific legal rights, and you may also have other rights which vary from state to state. Certain disclaimers are not allowed in some states and therefore they may not apply to you under all circumstances.

NOTE: This warranty does not cover routine maintenance items such as lubricants, filters, blade sharpening and tune-ups, or adjustments such as brake adjustments, clutch adjustments or deck adjustments. Nor does this warranty cover normal deterioration of the exterior finish due to use or exposure.
