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.

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. a. b. c. d. e. f. g. h. i. j. k. l. m. 1. 2. 3. 4. 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.

Tighten the wing knob on the upper chute making sure the carriage bolt is correctly positioned. Refer to Fig. 3-7. 1. 2. Figure 3-6 Chute Control Figure 3-7

Auger Control Periodic adjustment to the auger control cable may be required due to normal stretch and wear on the belt. Adjustment is needed immediately if the augers: Continue to turn with the auger control disengaged, or During operation, augers seem to hesitate turning while the engine maintains speed. NOTE: Perform the following test before operating the snow thrower for the first time and at the start of each winter season. Check the adjustment of the auger control as follows: When the auger control is released and in the disengaged “up” position, the cable should have very little slack, but should NOT be tight. In a well-ventilated area, start the snow thrower engine. Refer to Starting The Engine on page 12 in the Operation section on this manual. Make sure the throttle is set in the FAST position. While standing in the operator’s position (behind the snow thrower) engage the auger. Allow the auger to remain engaged for approximately 10 seconds before releasing the auger control. Repeat this several times. With the engine running in the FAST position and the auger control in the disengaged “up” position, walk to the front of the machine. Confirm that the auger has completely stopped rotating and shows NO signs of motion. NOTE: If the auger shows ANY signs of rotating, immediately return to the operator’s position and shut off the engine. Wait for all moving parts to stop before adjusting the auger control cable as follows: Loosen the rear hex bolt on the cable adjustment bracket. See Fig. 3-8. a. b. 1. 2. 3. 4. 5. 6. 7. Slide the cable adjustment bracket forward adding a slight amount of slack in the auger cable. Retighten the rear hex bolt. Start engine and verify auger control engages and disengages properly. NOTE: If auger continues to rotate with the control disengaged, shut off engine and readjust. If during operation, augers seem to hesitate turning while the engine maintains speed, then the cable is too loose and the bracket needs to be adjusted rearward, decreasing the amount of slack to the auger cable. Follow the above steps to adjust the cable adjustment bracket. WARNING! Do not over-tighten the cable. Over- tightening may prevent the auger from disengaging and compromise the safety of the snow thrower. 8. 9. 10. 11. Figure 3-8

Never store the snow thrower with fuel in the tank indoors or in poorly ventilated areas, where fuel fumes may reach an open flame, spark or pilot light as on a furnace, water heater, clothes dryer or gas appliance. NOTE: It is important to prevent gum deposits from forming in essential fuel system parts of the engine such as the carburetor, fuel filter, fuel hose or tank during storage. CAUTION: Alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage for 30 days or longer. Follow these instructions to prepare your snow thrower for storage: WARNING! Drain fuel into an approved container outdoors, away from any open flame. Be certain engine is cool. Do not smoke. Fuel left in engine during warm weather deteriorates and will cause serious starting problems. 1. Run the engine until the fuel tank is empty and it stops due to lack of fuel. WARNING! Do not drain carburetor if using fuel stabilizer. Never use engine or carburetor cleaning products in the fuel tank or permanent damage may occur. NOTE: Fuel stabilizer (such as STA-BIL™ or ULTRA-FRESH™) is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage container. Always follow mix ratio found on stabilizer container. Run engine at least 10 minutes after adding stabilizer to allow it to reach the carburetor. Do not drain carburetor if using fuel stabilizer. 2. Remove the spark plug and pour one (1) ounce of engine oil through the spark plug hole into the cylinder. Cover spark plug hole with a rag and crank the engine several times to distribute the oil. Replace spark plug. Preparing The Snow Thrower 1. When storing the snow thrower in an unventilated or metal storage shed, care should be taken to rustproof the equipment. Using a light oil or silicone, coat the equipment, especially any chains, springs, bearings and cables. 2. Remove all dirt from exterior of engine and equipment. 3. Follow lubrication recommendations in the Maintenance section of this manual. 4. Store equipment in a clean, dry area. Lubrication 1. Lubricate pivot points on the auger control and drive control with a light engine oil once a season, see Fig. 6-2. 2. Lubricate the auger idler bracket with a light engine oil once a season. See Fig. 6-2. Auger Shaft At least once a season, remove the shear pins from the auger shaft. Spray lubricant inside the shaft and around the spacers and the flange bearings found at either end of the shaft. See Fig. 6-3. Wheels At least once a season, remove both wheels. Clean and coat the axles with a multipurpose automotive grease before reinstalling wheels. Figure 6-2 Figure 6-3

cotter pins. If you hit a foreign object or ice jam, the snow thrower is designed so that the pins may shear. Refer to Fig. 6-1. If the augers do not turn, check if the pins have sheared. Replace, if needed, with proper shear pins. Refer to Parts List for correct part number. IMPORTANT: NEVER replace the auger shear pins with standard pins or fasteners. Any damage to the auger gearbox or other components, as a result of doing so, will NOT be covered by your snow thrower’s warranty. Replacing Belts NOTE: There are two belts on this snow thrower: an auger belt and drive belt. It is recommended that both belts be replaced at the same time. 1. Remove the spark plug wire from spark plug and ground it against the engine to prevent accidental starting. 2. Drain gasoline from the gas tank or place a piece of plastic sheet underneath the gas cap to prevent gasoline leakage. WARNING! Perform belt maintenance outdoors as some gas may possibly leak from the carburetor even though you placed a sheet of plastic underneath the gas cap to prevent the gas cap from leaking. 3. Remove the self-tapping screw shown in Fig. 7-1, and press the plastic tabs to release the belt cover. Pull the belt cover up and out from around the engine and chute assembly. Set it aside and save. Auger Belt IMPORTANT: Gas could leak from the carburetor at this point, the gas cap should have been covered with plastic as previously instructed. 1. Tip the snow thrower up and forward so that it rests on the auger housing. Remove the belt keeper as called out in Figure 7-3. Return the snow thrower to its upright position to complete the following steps. 2. Slip the front auger belt off of the engine pulley pushing it forward and rolling in off of the pulley. See Fig. 7-2. 3. Squeeze the auger control handle to release the auger brake, which is the tab that holds the belt onto the auger pulley. Remove the belt. 4. Replace with new belt after replacing the drive belt. Figure 7-1 Plastic Tab Figure 7-2 Drive Belt Engine Pulley Auger Belt Auger Pulley Idler Bracket Belt Keeper

Drive Belt NOTE: Replace the drive belt before reassembling the new auger belt. 1. Tip the snow thrower up and forward so that it rests on the auger housing. IMPORTANT: Remember, gas could leak from the carburetor at this point, the gas cap should have been covered with plastic as previously instructed. 2. Remove the spring that connects the transmission to a bolt on the engine frame. See Fig. 7-3. NOTE: It may be easier to first remove the flange lock nut, then use needle-nosed pliers to firmly grip spring and remove from bolt. Figure 7-3 Drive Pulley Belt Keeper Drive Belt Spring 3. Pivot the transmission forward to release pressure on the drive belt. Remove belt from transmission pulley. 4. Remove the drive belt from around the engine pulley, and away from the unit. 5.
