Use extreme care when handling gasoline. Gasoline is extremely flammable and the vapors are explosive.
Auger Control Ignition Key The ignition key is a safety devise. It must be fully inserted in order for the engine to start. Remove the ignition key when the snow thrower is not in use. Do not turn the ignition key in an attempt to start the engine. Doing so may cause it to break. ����� ������� Clean-Out Tool WARNING: Never use your hands to clear a clogged chute assembly. Shut off engine and remain behind handles until all moving parts have stopped before unclogging.
Gas & Oil Fill-Up WARNING Read, understand, and follow all instructions and warnings on the machine and in this manual before operating. Use extreme care when handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Never fuel the machine indoors or while the engine is hot or running. Extinguish cigarettes, cigars, pipes and other sources of ignition. If your home’s wiring system is not a three-wire grounded system, do not use this electric starter under any conditions.
To Engage Augers 4. Move throttle control to STOP position. 5. Remove the ignition key and store in a safe place. 1. To engage the augers and start throwing snow, squeeze the auger control against the left handle. Release to stop the augers. 6. Wipe all snow and moisture from the area around the engine as well as the area in and around the drive control and auger control. Also, engage and release both controls several times.
5 Making Adjustments Auger Control Refer to Auger Control Test on Page 11 to adjust the auger control. Drive Control When the drive control is released and in the disengaged “up” position, the cable should have very little slack. It should NOT be tight. Check the adjustment of the drive control as follows: 1. With the drive control released, push the snow thrower gently forward. The unit should roll freely. 2. Engage the drive control and gently attempt to push the snow thrower forward.
5 Skid Shoes The space between the skid shoes and the ground can be adjusted. See Figure 5. • For close snow removal on a smooth surface, raise skid shoes higher on the auger housing. • Use a middle or lower position when the area to be cleared is uneven, such as a gravel driveway. Making Adjustments To adjust the skid shoes: 1. Loosen the four hex nuts (two on each side) and carriage bolts. Move skid shoes to desired position. 2.
6 Maintaining Your Snow Thrower Engine Refer to the separate Tecumseh Engines manual packed with your unit for all engine maintenance. Lubrication Engine Refer to the separate Tecumseh Engines manual packed with your unit for all engine lubrication instructions. Gear Shaft The gear (hex) shaft should be lubricated at least once a season or after every 25 hours of operation. 1. Remove the lower frame cover by removing the two screws which secure it. 2.
Auger Belt Replacement 1 To remove and replace your snow thrower’s auger belt, proceed as follows: 1. Remove the plastic belt cover on the front of the engine by removing the two self-tapping screws. NOTE: Drain the gasoline from the snow thrower, or place a piece of plastic under the gas cap. 2. Carefully pivot the snow thrower up and forward so that it rests on the auger housing. Remove the frame cover from the underside of the snow thrower by removing four self-tapping screws which secure it.
6 Augers 1 • The augers are secured to the spiral shaft with two shear pins and cotter pins. If the auger should strike a foreign object or ice jam, the snow thrower is designed so that the pins may shear. Refer to Figure 9. • Maintaining Your Snow Thrower If the augers will not turn, check to see if the pins have sheared. One set of replacement shear pins has been provided with the snow thrower. When replacing pins, spray an oil lubricant into shaft before inserting new pins.
1 Friction Wheel Removal If the snow thrower fails to drive with the drive control engaged, and performing the drive control cable adjustment on page 14 fails to correct the problem, the friction wheel may need to be replaced. Follow the instructions below. Examine the friction wheel for signs of wear or cracking and replace if necessary • Place the shift lever in third Forward (F3) position. • Drain the gasoline from the snow thrower, or place a piece of plastic under the gas cap.
7 Off-Season Storage WARNING Never store snow thrower with fuel in 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. 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.
Problem Cause Remedy 1. Choke not in ON position. 1. Move choke to ON position. 2. Spark plug wire disconnected. 2. Connect wire to spark plug. 3. Fuel tank empty or stale fuel. 3. Fill tank with clean, fresh gasoline. 4. Engine not primed. 4. Prime engine as instructed in “Operating Your Snow Thrower”. 5. Faulty spark plug. 5. Clean, adjust gap, or replace. 6. Blocked fuel line. 6. Clean fuel line. 7. Safety key not in ignition on engine. 7. Insert key fully into the switch. 1.
