SAFETY INSTRUCTIONS
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.
•Use only an approved gasoline container.
•Extinguish all cigarettes, cigars, pipes and other sources of ignition.
•Never fuel machine indoors.
•Never remove gas cap or add fuel while the engine is hot or running.
•Allow engine to cool at least two minutes before refueling.
•Never over fill fuel tank. Fill tank to no more than ½ inch below bottom of filler neck to provide space for fuel expansion.
•Replace gasoline cap and tighten securely.
•If gasoline is spilled, wipe it off the engine and equipment. Move machine to another area. Wait 5 minutes before starting the engine.
•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.).
•Allow machine to cool at least 5 minutes before storing.
•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.
•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.
•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
•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.
•The auger/impeller control lever is a safety device. Never bypass its operation. Doing so makes the machine unsafe and may cause personal injury.
•The control levers must operate easily in both directions and automatically return to the disengaged position when released.
•Never operate with a missing or damaged chute assembly. Keep all safety devices in place and working.
•Never run an engine indoors or in a poorly ventilated area. Engine exhaust contains carbon monoxide, an odorless and deadly gas.
•Do not operate machine while under the influence of alcohol or drugs.
•Muffler and engine become hot and can cause a burn. Do not touch. Keep children away.
•Exercise extreme caution when operating on or crossing gravel surfaces. Stay alert for hidden hazards or traffic.
•Exercise caution when changing direction and while operating on slopes.
•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.
•Never direct discharge at children, bystanders and pets or allow anyone in front of the machine.
•Do not overload machine capacity by attempting to clear snow at too fast of a rate.
•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.
•Disengage power to the auger/impeller when transporting or not in use.
•Never operate machine at high transport speeds on slippery surfaces. Look down and behind and use care when backing up.
•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.
•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.
•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.
•Use only attachments and accessories approved by the manufacturer (e.g. wheel weights, tire chains, cabs etc.).
•When starting engine, pull cord slowly until resistance is felt, then pull rapidly. Rapid retraction of starter cord (kickback) will pull hand and arm toward engine faster than you can let go. Broken bones, fractures, bruises or sprains could result.
•If situations occur which are not covered in this manual, use care and good judgment. Contact Customer Support for assistance and the name of your nearest servicing dealer.

WARNING
To avoid unsupervised engine operation, never leave the machine unattended with the engine running. Turn the engine off after use and remove ignition key.
Stopping The Engine
After you have finished snow-throwing, run engine for a few minutes before stopping to help dry off any moisture on the engine.
1.Move throttle control to STOP STOP position.
2.Remove the ignition key. Removing the key will reduce the possibility of unauthorized starting of the engine while equipment is not in use. Keep the key in a safe place. The engine cannot start without the ignition key.
3.Wipe any moisture away from the controls on the engine.
To Engage Drive
1. With the throttle control in the Fast (rabbit) position, move shift lever into one of the six forward (F) positions or two reverse
(R) positions. Select a speed appropriate for the snow conditions and a pace you’re comfortable with.
NOTE: When selecting a Drive Speed, use the slower speeds until you are comfortable and familiar with the operation of the snow thrower.
2.Squeeze the drive control against the handle and the snow thrower will move. Release it and drive motion will stop.
NOTE: NEVER reposition the shift lever (change speeds or direction of travel) without first releasing the drive control and bringing the snow thrower to a complete stop. Doing so will result in premature wear to the snow thrower’s drive system.
To Engage Augers
1.To engage the augers and start throwing snow, squeeze the auger control against the left handle. Release to stop the augers.
Replacing Shear pins
The augers are secured to the spiral shaft with two shear pins and bow-tie clips. If the auger should strike a foreign object or ice jam, the snow thrower is designed so that the shear pins may shear. If augers will not turn, check to see if the pins have sheared. See Figure 11.
CAUTION
NEVER replace the auger shear pins with anything other than Sears SKU# 88389/OEM Part No. 738-04124A replacement shear pins. Any damage to the auger gearbox or other components as a result of failing to do so will NOT be covered by your snow thrower’s warranty.
WARNING
Always turn off the snow thrower’s engine and remove the key prior to replacing shear pins.

ENGINE MAINTENANCE
WARNING
Before lubricating, repairing, or inspecting, disengage all controls and stop engine. Wait until all moving parts have come to a complete stop.
Checking Engine Oil
NOTE: Check the oil level before each use to be sure correct oil level is maintained.
When adding oil to the engine, refer to viscosity chart below. Engine oil capacity is 600 ml (approx. 20 oz.). Do not over-fill. Use a 4-stroke, or an equivalent high detergent, premium quality motor oil certified
to meet or exceed U.S. automobile manufacturer’s requirements for service classification SG, SF. Motor oils classified SG, SF will show this designation on the container.
1.Remove the oil filler cap/dipstick and wipe the dipstick clean.
2.Insert the cap/dipstick into the oil filler neck, but do not screw it in.
3.Remove the oil filler cap/dipstick. If level is low, slowly add oil until oil level registers between high (H) and low (L). See Figure 12.
4.Replace and tighten cap/dipstick firmly before starting engine.
Changing Engine Oil
NOTE: Change the engine oil after the first 5 hours of operation and once a season or every 50 hours thereafter.
1.Drain fuel from tank by running engine until the fuel tank is empty. Be sure fuel fill cap is secure.
2.Place suitable oil collection container under oil drain plug.
3.Remove oil drain plug. See Figure 13.
4.Tip engine to drain oil into the container. Used oil must be disposed of at a proper collection center.
CAUTION
Used oil is a hazardous waste product. Dispose of used oil properly. Do not discard with household waste. Check with your local authorities or Sears Service Center for safe disposal/recycling facilities.
5.Reinstall the drain plug and tighten it securely.
6.Refill with the recommended oil and check the oil level. See Recommended Oil Usage chart. The engine’s oil capacity is 20 ounces.

SERVICE AND MAINTENANCE
Checking Spark Plug
WARNING
DO NOT check for spark with spark plug removed. DO NOT crank engine with spark plug removed.
WARNING
If the engine has been running, the muffler will be very hot. Be careful not to touch the muffler.
NOTE: Check the spark plug once a season or every 25 hours of operation. Change the spark plug once a season or every 100 hours. To ensure proper engine operation, the spark plug must be properly gapped and free of deposits.
1.Remove the spark plug boot and use a spark plug wrench to remove the plug. See Figure 14.
2.Visually inspect the spark plug. Discard the spark plug if there is apparent wear, or if the insulator is cracked or chipped. Clean the spark plug with a wire brush if it is to be reused.
3.Measure the plug gap with a feeler gauge. Correct as necessary by bending side electrode. See Figure 15. The gap should be set to .02-.03 inches (0.60-0.80 mm).
4.Check that the spark plug washer is in good condition and thread the spark plug in by hand to prevent cross-threading.
5.After the spark plug is seated, tighten with a spark plug wrench to compress the washer.
NOTE: When installing a new spark plug, tighten 1⁄2-turn after the spark plug seats to compress the washer. When reinstalling a used spark plug, tighten 1⁄8- to 1⁄4-turn after the spark plug seats to compress the washer.
CAUTION
The spark plug must be tightened securely. A loose spark plug can become very hot and can damage the engine.
Lubrication
Gear Shaft
The gear (hex) shaft should be lubricated at least once a season or after every 25 hours of operation.
1.To prevent spillage, remove all fuel from tank by running engine until it stops.
2.Carefully pivot the snow thrower up and forward so that it rests on the auger housing.
3.Remove the lower frame cover from the underside of the snow thrower by removing the four self-tapping screws which secure it.
4.Apply a light coating of engine oil (or 3-in-1 oil) to the hex shaft. See Figure 16.
NOTE: When lubricating the hex shaft, be careful not to get any oil on the aluminum drive plate or rubber friction wheel. Doing so will hinder the snow thrower’s drive system. Wipe off any excess or spilled oil.
