CHECKS BEFORE EACH START-UP The first stage is the auger, which feeds the snow back into the impeller housing. The second stage is the impeller, which throws the snow out the discharge chute. If bodily contact is made with the auger or impeller when they are rotating, severe personal injury will occur. 1. Make sure all safety guards are in place and all nuts, bolts and clips are secure. 2. Check to make sure that the clean-out is attached to the handle on the machine. Do not operate the machine without the clean-out tool properly stored on the handle. To avoid injury, keep others and yourself away from the auger and the discharge chute whenever the engine is running. Read and follow all of the safety rules and warnings in this manual. 3. Check the engine oil level. See your engine owner’s manual for procedure and specifications. 4. Check to make sure spark plug wire is attached and spark plug is tightened securely. If necessary, torque spark plug to 15 ft. lbs. DANGER 5. Check the fuel supply. Fill the tank no closer than 1/4 to 1/2 inch of top of tank to provide space for expansion. See your engine owner’s manual for fuel recommendations. Do not clean out discharge chute with hands. Contact with moving parts inside chute will cause serious injury. Use clean out tool provided with machine. Use the following procedure to remove objects or clear the chute: 6. Check the scraper bar to make sure it is set at the desired height. Adjust the skid shoes if necessary. 1. Stop the engine. Remove the key 2. Wait 10 seconds to be sure the auger/impeller blades have stopped rotating. 3. Always use the clean-out tool. DO NOT use your hands. 7. Check the drive control (B, Figure 2), and auger control (C) for proper operation. If adjustment is required, see the service section for procedures. 8. Check the chute direction control (D, Figure 2) for proper operation. The discharge chute should rotate freely in both directions. See the service section for adjustment procedures and troubleshooting. 9. Check the chute deflector (E, Figure 2) for proper operation. The deflector should pivot freely up and down when the chute deflector knob is loosened. WARNING 10. Position the chute at the desired starting direction and set the deflector at the desired angle. For your safety, operation on slopes should be in an up and down direction only. If it becomes necessary to move across the face of a slope, use caution and do not blow snow. Be very careful when changing direction on a slope. 11. Check the speed selector (A, Figure 2) for smooth operation. The control must move freely into each speed position gate and remain in position when released. If the speed selector does not move freely into all forward and reverse speed positions, contact your local authorized dealer for assistance. Proper winter footwear is recommended for the operator to help prevent slipping. Never attempt to clean snow from excessively steep slopes. The maximum slope for any operation is 17.7% (10º). WARNING Gasoline is highly flammable and must be handled with care. Never fill the tank when the engine is hot or running. Always move outdoors to fill the tank.

Releasing the Easy Turn™ lever automatically engages both drive wheels for full traction. Figure 7. Traction Drive Lock A. Pin in Outer Hole (Freewheel) B. Pin in Inner Hole (Drive) 2. To DISENGAGE the traction drive lock, insert the Traction Lock Pin through the outer hole in the right axle. The unit can now be pushed with minimal resistance. NOTE: The Easy Turn™ lever will be more difficult to activate under a heavy load. Activate the lever before beginning a turn. When Pushing the Snowthrower: 3. To ENGAGE the traction drive lock, align the hole in the hub with the inner hole in the axle, and install the Traction Lock Pin. For easy turning when pushing the snowthrower, disengage the right wheel using the traction lock pin (See Figure 7.) NOTE: Be sure both wheels are locked (locking pin in inner hole) when clearing snow. 1. Turn the unit off, remove the engine key, and disconnect the spark plug wire. 14 Storage AFTER EACH USE WARNING Normal use of the snowthrower may result in a build-up of packed snow in and around the starter cord housing and around engine controls. Heat from the engine will usually prevent the snow from freezing solid while the unit is running, but after the engine is shut down, some snow may continue melting from engine heat, and later freeze around some moving parts as the unit cools. Never store the unit, with gasoline in engine or fuel tank, in a heated shelter or in enclosed, poorly ventilated enclosures. Gasoline fumes may reach an open flame, spark or pilot light (such as a furnace, water heater, clothes dryer, etc.) and cause an explosion. After each period of use, follow these steps to prevent freeze-up caused by ice formation in and around the engine controls and external parts. Handle gasoline carefully. It is highly flammable and careless use could result in serious fire damage to your person or property. 1. Before shutting off the engine, pull the starter rope out 2 - 3 times, and allow it to rewind slowly. This will help clear packed snow from the starter cord area. Allow the engine to run for several minutes. Drain fuel into an approved container outdoors away from open flame or sparks. 2. Stop the engine by moving the throttle lever (See Figure 1) down, or by pulling out the engine key. 3. Brush snow and ice from the snowthrower. Be sure to clear engine and snowthrower controls, discharge chute, worm and chute rod gears, clutch cable areas, and anywhere else snow has accumulated. STORAGE WARNING Never store the unit (with fuel) in an enclosed, poorly ventilated structure. Fuel vapors can travel to an ignition source (such as a furnace, water heater, etc.) and cause an explosion. 4. Always remove the engine key and store in a safe place to prevent unauthorized use. 5. If the snowthrower is kept in a cold shelter, fill the fuel tank to prevent condensation. Do not store near sparks or flame. Fuel vapor is also toxic to humans and animals. Note: The Engine Owner’s Manual contains further information on preventing ice formation and freeze-up. Before you store your unit for the off-season, read the Maintenance and Storage instructions in the Safety Rules section, then perform the following steps: • Disengage the PTO, set the parking brake, and remove the key. • Perform engine maintenance and storage measures listed in the engine owner’s manual. This includes draining the fuel system, or adding stabilizer to the fuel (do not store a fueled unit in an enclosed structure - see warning). Before starting the unit after it has been stored: • Check all fluid levels. Check all maintenance items. • Perform all recommended checks and procedures found in the engine owner’s manual. • Allow the engine to warm up for several minutes before use. 15 Regular Maintenance MAINTENANCE SCHEDULE MAINTENANCE REQUIRED FREQUENCY NOTES Check auger gear case lubrication.** 25 Hours Winter Weight Worm Gear Oil Lubricate snowthrower. 10 Hours 10W Oil and Grease Check tire pressure.

Place the snowthrower on a level surface. 2. Remove the pipe plug (A, Figure 9). 3. Check the lubricant level. It should be level with the lower edge of the plug opening. If not, add The Dealer Line Winter Weight Worm Gear Oil (available from your dealer). 4. Re-install pipe plug, and tighten securely. Pipe Plug Figure 9. Auger Lubrication A. Pipe Plug 16 Regular Maintenance LUBRICATION IMPORTANT NOTE It is very important that grease fittings on the auger shaft are lubricated regularly. If auger rusts to shaft, damage to worm gear may occur if shear pins do not break. To prevent wheels rusting to axles, it is also necessary to remove the wheels and grease the axles regularly. Remove wheels and grease axles once each year. Figure 10. Chute Lubrication Apply medium weight (10W) oil to points shown (See Figures 10-13). A Apply 5W-50 synthetic motor oil to the friction disk drive hex shaft (A, Figure 11). Generally, all moving metal parts should be oiled where contact is made with other parts. Keep oil and grease off belts, pulley grooves, drive disc, and friction disc. LUBRICATION NOTES: Grease locations indicated by grease gun symbol. Use grease fittings when present. Disassemble parts to apply grease to moving parts when grease fittings are not installed. Figure 11. Drive Lubrication A. Hex Shaft Oil locations indicated by oil can symbol. Do not allow oil to drip onto traction drive or friction disc. Do not lubricate remote deflector control. Figure 12. Grease Axles & Lubricate Control Levers (Channel Handle Model Shown) Figure 13.
