RULES FOR SAFE OPERATION

MTF−051055L

Avoid death or serious injury from rotating auger. Keep hands, feet and clothing away. Unclogging discharge chute is a hazardous activity.

• Never attempt to clear auger of debris or clogged snow while equipment is

engaged or engine is running. Clogged or blocked augers store energy and can rotate unexpectedly, EVEN WITH ENGINE OFF.

• Stop engine and disconnect spark plug wire when performing maintenance

on equipment.

• Never leave the equipment unattended while engine is running. Always

disengage the auger and traction controls, stop engine, and remove keys.

• Keep children, pets, and others out of the area during operation. Children

are often attracted to the equipment. Be mindful of all persons present.

• Keep all loose clothing far away from front of snow thrower and auger.

Scarfs, mittens, dangling drawstrings, loose clothes and pants can quickly become caught in the rotating device and dismemberment will occur. Tie up long hair and remove jewerly.

• The snow thrower is intended to remove snow only. Do not use for other

purposes other than what is intended.

• Do not clear snow across the face of slopes. Exercise extreme caution when

changing direction on slopes. Do not attempt to clear steep slopes.

• Do not use the snow thrower on surfaces above ground level such as roofs

of residences, garages, porches or other such structures or buildings.

DANGER

Discharge chute contains rotating impeller to throw snow. Never clear or unclog discharge chute with your hands, or while engine is running.

Fingers can quickly become caught and traumatic amputation or severe laceration can result.

• Unclogging the discharge chute is a hazardous activity. Clogged or

blocked augers store energy and can rotate unexpectedly.

• Never place hands in or near discharge chute.

• With engine OFF, wait for all moving parts to cease movement, then with a

stick, clear the chute. Even with engine off, parts may rotate and dismemberment can occur.

• Clogged snow can hide other obstructions in the chute and cause damage

to the equipment, impeller or auger. Take precautions when restating the equipment after snow removal.

DANGER

Objects can be picked up by auger and thrown from chute. Never throw snow toward people or cars, and never allow

anyone in front of the snow thrower.

• Be aware of your enviroment while operating equipment. Running over

items such as, gravel, doormats, newspapers, toys, and rocks hidden under snow, can all be thrown from chute or jam in the auger.

• Always be aware of the direction the snow is being thrown. Nearby

pedestrians, pets or property may be harmed by objects being thrown.

• Familiarize yourself with the area you plan to work. Mark off boundarties of

walkways and driveways to prevent property damage, or throwing objects.

• Take caution when snow throwing in unfamiliar areas. Stay alert for hidden

hazards and traffic.

• After striking a foreign object, turn engine OFF, wait for moving parts to

cease movement, and check immediately for damage. If damaged, repair before starting and operating snow thrower.

• With engine OFF, wait for moving parts to stop and always use a stick to

clear discharge chute.

• If unit vibrates abnormally, turn engine OFF. Vibration is generally a

warning of trouble. See an authorized dealer if necessary for repairs.

DANGER

Rotating gears can contact or entangle hands, feet, hair, clothing, or accessories.

Traumatic amputation or severe laceration can result.

• Always operate equipment with all guards in place.

• Keep hands and feet away from rotating gears.

• Tie up long hair and remove jewelry.

• Do not wear loose-fitting clothing, dangling drawstrings or items that could

become caught.

WARNING

Engines give off carbon monoxide, an odorless, colorless, poison gas.

Breathing carbon monoxide can cause nausea, fainting or death.

• Start and run engine outdoors.

• Do not start or run engine in enclosed area, even if doors or

windows are open.

WARNING

RULES FOR SAFE OPERATION

MTF−051055L

Gasoline and its vapors are extremely flammable and explosive. Fire or explosion can cause severe burns or death.

WHEN ADDING FUEL

• Turn engine OFF and let engine cool at least 2 minutes before removing

gas cap.

• Fill fuel tank outdoors or in well-ventilated area.

• Do not overfill fuel tank.

• Keep gasoline away from sparks, open flames, pilot lights, heat, and other

ignition sources.

• Check fuel lines, tank, cap, and fittings frequently for cracks or leaks.

Replace if necessary.

WHEN STARTING ENGINE

• Make sure spark plug, muffler, fuel cap and air cleaner are in place.

• Do not crank engine with spark plug removed.

• If fuel spills, wait until it evaporates before starting engine.

• If engine floods, set choke to OPEN/RUN position, place throttle in FAST

and crank until engine starts.

WHEN OPERATING EQUIPMENT

• Do not choke carburetor to stop engine.

WHEN TRANSPORTING EQUIPMENT

• Transport with fuel tank EMPTY.

WHEN STORING GASOLINE OR EQUIPMENT WITH FUEL IN TANK

• Store away from furnaces, stoves, water heaters or other appliances that

have pilot light or other ignition source because they can ignite gasoline vapors.

WARNING

Starting engine creates sparking. Sparking can ignite nearby flammable gases. Explosion and fire could result.

• If there is natural or LP gas leakage in area, do not start engine.

• Do not use pressurized starting fluids because vapors are flammable.

WARNING

• Allow muffler, engine cylinder and fins to cool before touching.

• Remove accumulated combustibles from muffler area and cylinder

area.

• Install and maintain in working order a spark arrester before using

equipment on forest-covered, grass-covered, brush-covered unimproved land. The state of California requires this (Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal land.

WARNING

Running engines produce heat. Engine parts, especially muffler, become extremely hot.

Severe thermal burns can occur on contact. Combustible debris, such as leaves, grass, brush, etc. can catch

fire.

Unintentional sparking can result in fire or electric shock. Unintentional start-up can result in entanglement, traumatic

amputation, or laceration.

BEFORE PERFORMING ADJUSTMENTS OR REPAIRS

• Disconnect spark plug wire and keep it away from spark plug.

WHEN TESTING FOR SPARK

• Use approved spark plug tester.

• Do not check for spark with spark plug removed.

FILL GAS

This engine is certified to operate on gasoline. Exhaust Emission Control System: EM (Engine Modifications)

1. Fill the fuel tank with fresh, clean, unleaded regular, unleaded premium, or reformulated automotive gasoline with a minimum of 85 octane along with a fuel stabilizer (follow instructions on fuel stabilizer package). DO NOT use leaded gasoline. We recommend that fuel stabilizer be added to the fuel each time that gasoline is added to the fuel tank.

NOTE: Winter grade gasoline has higher volatility to improve starting. Be certain container is clean and free from rust or other foreign particles. Never use gasoline that may be stale from long periods of storage in the container.

CAUTION: DO NOT use gasoline containing any amount of alcohol as it can cause serious damage to the engine or significantly reduce the performance.

WARNING: Gasoline is flammable. Always use caution when handling or storing gasoline.

Turn engine off and let engine cool at least two minutes before removing the gas cap. Do not add gasoline to the fuel tank while snow blower is running, hot, or when snow blower is in an enclosed area. Keep away from open flame, electrical sparks and DO NOT SMOKE while filling the fuel tank. Never fill the fuel tank completely; but fill the fuel tank to within 1-1/2 inch (3.8 mm) from the top to provide space for the expansion of the fuel. Always fill fuel tank outdoors and use a funnel or spout to prevent spilling. Make sure to wipe up any spilled fuel before starting the engine. Store gasoline in a clean, approved container, and keep the cap in place on the container. Keep gasoline in a cool well ventilated place; never in the house. Never buy more than a 30 day supply of gasoline to assure volatility. Gasoline Is intended to be used as a fuel for internal combustion engines; therefore, do not use gasoline for any other purpose. Since many children like the smell of gasoline, keep it out of their reach because the fumes are dangerous to inhale, as well as being explosive.

OPERATION

MTF−051055L

OPERATING TIPS

1. Most efficient snowblowing is accomplished when snow is removed immediately after it falls.

2. For complete snow removal, slightly overlap each swath previously taken.

3. Snow should be discharged downwind whenever possible.

4. For normal usage, set the skids one−eighth inch (3 mm) below the scraper bar. For extremely hard−packed snow surfaces, the skids may be adjusted upward to insure cleaning efficiency.

5. On gravel or crushed rock surfaces, the skids should be set at 1−1/4 inch (32 mm) below the scraper bar (see To Adjust Skid Height, in the Adjustment/Repair section in this manual). Rocks and gravel must not be picked up and thrown by the machine.

6. After the snowblowing job has been completed, allow the engine to idle for a few minutes, to melt snow and ice accumulated on the engine.

7. Clean the snow thrower thoroughly after each use.

8. Remove ice and snow accumulation and all debris from the entire snow thrower, and flush with water (if possible) to remove all salt or other chemicals. Wipe snow thrower dry.

9. Before starting snow blower, always inspect augers and impeller for ice accumulation and/or debris, which could result in snow blower damage.

10. Check oil level before every start. Make sure the oil is at the FULL mark on the oil fill cap/dipstick.

ENGINE

POWER RATINGS

The power ratings for an individual engine model are initially developed by starting with SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure) (Revision 2002-05). Given both the wide array of products on which our engines are placed, and the variety of environmental issues applicable to operating the equipment, it may be that the engine you have purchased will not develop the rated horsepower when used in a piece of power equipment (actual “on-site” power). This difference is due to a variety of factors including, but not limited to, the following: differences in altitude, temperature, barometric pressure, humidity, fuel, engine lubrication, maximum governed engine speed, individual engine to engine variability, design of the particular piece of power equipment, the manner in which the engine is operated, engine run-in to reduce friction and clean out of combustion chambers, adjustments to the valves and carburetor, and other factors. The power ratings may also be adjusted based on comparisons to other similar engines utilized in similar applications, and will therefore not necessarily match the values derived using the foregoing codes.

Check Crankcase Oil Level before starting engine and after each 8 hours of continuous use (see Figure 23). Add the recommended motor oil as required.

NOTE: Overfilling the engine can affect performance. Tighten the oil fill cap securely to prevent leakage.

Change Oil every 50 hours of operation or at least once a

year, even if the snow blower is not used for fifty hours. Use a clean, high quality detergent oil. Fill the crank case to FULL line on dipstick (see Figure 23). Be sure original container is marked: A.P.I. service “SF” or higher. Do not use SAE10W40 oil (as it may not provide proper lubrication). See Chart for oil recommendations.

To Drain Oil − Position snow blower so that the oil drain plug is lowest point on engine. When the engine is warm, remove oil drain plug and oil fill cap and drain oil into a suitable container (Figure 24).

Replace oil drain plug and tighten securely. Refill crank case with the recommended motor oil.

AUGER HOUSING HEIGHT ADJUSTMENT

TO ADJUST SCRAPER BAR

After considerable use, the metal scraper bar will have a definite wear pattern. The scraper bar in conjunction with the skids should always be adjusted to allow one−eighth of an inch (3 mm) between the scraper bar and the sidewalk or area to be cleaned.

To adjust the scraper bar, proceed as follows:

1. Position the snowthrower on a level surface.

2. Loosen the carriage bolts and nuts securing the scraper bar to the auger housing.

3. Adjust the scraper bar to the proper position. Tighten the carriage bolts and nuts, insuring that the scraper bar is parallel with the working surface.

4. For extended operation, the scraper bar may be reversed. If the scraper bar must be replaced because of wear, remove the carriage bolts and nuts and install a new scraper bar.

TO ADJUST SKID HEIGHT

This snowthrower is equipped with two height adjust skids, secured to the outside of the auger housing. These elevate the front of the snowthrower.

When removing snow from a hard surface area such as a paved driveway or walk, adjust the skids up to bring the front of the snowthrower down.

When removing snow from rock or uneven construction, raise the front of the snowthrower by moving the skids down. This will help to prevent rocks and other debris from being picked up and thrown by the augers.

To adjust skids, proceed as follows:

1. Place a block (equal to height from ground desired) under scraper bar near but not under skid.

2. Loosen skid mounting nuts (Figure 29) and push the skid down until it touches the ground. Retighten mounting nuts.

3. Set skid on other side at same height.

NOTE: Make sure that snowthrower is set at same height on both sides.

WARNING: Be certain to maintain proper ground clearance for your particular area to be

cleared. Objects such as gravel, rocks or other debris, if struck by the impeller, may be thrown with sufficient force to cause personal injury, property damage or damage to the snowthrower.

STORAGE

MTF−051055L

OFF SEASON STORAGE

WARNING: Never store the engine, with fuel in the tank, indoors or in a poor ventilated enclo-

sure where fuel fumes could reach an open flame, spark or pilot light as on a furnace, water heater, clothes dryer, etc. Handle gasoline carefully. It is highly flammable and careless use could result In serious fire damage to your person and /or property. Drain fuel into approved containers outdoors, away from open flame.

If the snowthrower is to be stored for thirty (30) days or more at the end of the snow season, the following steps are recommended to prepare your snowthrower for storage.

NOTE: Gasoline must be removed or treated to prevent gum deposits from forming in the tank, filter, hose, and carburetor during storage.

1. To remove gasoline, run engine until tank is empty and engine stops.

If you do not want to remove the gasoline, add fuel stabilizer to any gasoline left in the tank to minimize gum deposits and acids. If the tank is almost empty, mix stabilizer with fresh gasoline in a separate container and add some to the tank. ALWAYS FOLLOW INSTRUCTIONS ON STABILIZER CONTAINER. THEN RUN ENGINE AT LEAST 10 MINUTES AFTER STABILIZER IS ADDED TO ALLOW MIXTURE TO REACH CARBURETOR. STORE SNOWTHROWER IN SAFE PLACE.

2. You can help keep your engine (4−cycles only) in good operating condition by changing oil before storage.

3. Lubricating the piston/cylinder area. This can be done by first removing the spark plug and squirting clean engine oil into the spark plug hole. Then cover the spark plug hole with a rag to absorb oil spray. Next, rotate the engine by pulling the starter two or three times. Finally, reinstall spark plug and attach spark plug wire.

4. Thoroughly clean the snowthrower.

5. Lubricate all lubrication points (see “Lubrication“ in the Maintenance section).

6. Insure that all nuts, bolts, and screws are securely fastened. Inspect all visible moving parts for damage, breakage, and wear. Replace if necessary.

7. Touch up all rusted or chipped paint surfaces; sand lightly before painting.

8. Cover the bare metal parts of the snowthrower housing auger, and the impeller with rust preventative.

9. If possible, store your snowthrower indoors and cover it to give protection from dust and dirt.

10. On models with folding handles, loosen the knobs that secure the upper handle. Rotate the upper handle back.

11. If the machine must be stored outdoors, block up the snowthrower and insure the entire machine is off the ground. Cover the snowthrower with a heavy tarpaulin.

REMOVING THE SNOWTHROWER FROM STORAGE

When removing the snowthrower from storage, follow the steps below.

1. Put the upper handle in the operating position, tighten the knobs that secure the upper handle.

2. Fill the fuel tank with a fresh fuel.

3. Check the spark plug. Make sure the gap is correct. If the spark plug is worn or damaged, replace before using.

4. Make sure all fasteners are tight.

5. Make sure all guards, shields, and covers are in place.

6. Make sure all adjustments are correct.
