SECTION 1: IMPORTANT SAFE OPERATION PRACTICES WARNING: This symbol points out important safety instructions which, if not followed, could endanger the personal safety and/or property of yourself and others. Read and follow all instructions in this manual before attempting to operate this machine. Failure to comply with these instructions may result in personal injury. When you see this symbol - heed its warning.

Never operate with a missing or damaged discharge chute. 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.
SECTION 2: ASSEMBLING YOUR SNOW THROWER NOTE: Any reference in this manual to the left or right side of the snow thrower is observed from the operator’s position. • • Unpacking • • • • • Raise the upper handle assembly until it locks over the lower handle. Look at lower rear of snow thrower frame to be sure both cables are aligned with cable roller guides. See Figure 3. Remove staples from the top sides and ends of the shipping crate. Set panel aside to avoid tire punctures or personal injury.
snow thrower, the machine should otherwise move freely. b. Engage the traction control and attempt to move the machine both forward and rearward. You should experience resistance as the wheels should not be turning. • Move the shift lever into the fast reverse (R2) position and repeat the previous steps (a & b).
• • Retighten the hex nuts loosened earlier. Repeat this adjustment on the skid shoe found on the opposite side of the snow thrower. Tire Pressure The tires are overinflated for shipping purposes. • Check tire pressure, by referring to tire sidewalls for recommended tire pressure. NOTE: If the tire pressure is not equal in all tires, the unit may pull to one side or the other. Skid Shoes WARNING: Maximum tire pressure under any circumstance is 30 psi.
Auger Drive Control To change the direction in which discharged snow is thrown, proceed as follows: • Push the toggle switch to the left to rotate the chute counterclockwise. • Push the toggle switch to the right to rotate the chute clockwise. The auger drive control is located on the left handle. Squeeze the control grip to engage the augers. Release to stop the snow throwing action. (Traction control must also be released.) See Figure 8.
WARNING: Use extreme care when handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Never fuel machine indoors or while the engine is hot or running. Extinguish cigarettes, cigars, pipes an other sources of ignition. • • • • • A plastic cup is provided inside the fuel fill opening on the fuel tank. Remove and discard this cup before filling up the tank. Use the separate fuel tank cap to close after fill-up.
NOTE: Keep it in a safe place. Engine will not start without ignition key. • Release both the auger control and the traction control, if engaged. The auger control can be locked so you can turn the electric chute directional control without interrupting the snow throwing process. Wipe all snow and moisture from the carburetor cover in the area of the control levers. Also, move control levers back and forth several times.
IMPORTANT: Make certain to check for correct adjustment of the shift rod as instructed under Final Adjustments in the Assembly Section, before operating the snow thrower.
Electric Chute-Rotation Motor Do not overfill the gear case. Damage to the seals could result. Be sure the vent plug is free of grease in order to relieve pressure. The gear on the electric chute-rotation motor and the base of the discharge chute itself should be lubed with multi-purpose automotive grease once a season. See Figure 11. Auger Shaft At least once a season, remove the shear bolts on the auger shaft. Spray lubricant inside the shaft.
Self-Tapping Screw Remove Belt Remove Belt Idler Pulley Belt Cover Figure 13 • Remove the three hex nuts and lock washers which attach the auger housing assembly to the frame assembly on each side. See Figure 14. Figure 15 WARNING: Do not attempt to change the auger belt without the help of an assistant. It is very important that one person, standing at the operating position, firmly hold the snow thrower housing to prevent it from tipping while the other person replaces the belt.
• • • • • Remove the plastic belt cover on the front of the engine by removing the two self-tapping screws. Tip the snow thrower up and forward, so that it rests on the housing. Remove six self-tapping screws from the frame cover underneath the snow thrower. Pull the idler pulley away from the drive belt and remove the belt from the engine pulley. Working from the underside of the frame, slip belt between the friction wheel and the friction wheel disc.
• • • • Reassemble new friction wheel rubber to the friction wheel assembly, tightening the six screws in rotation and with equal force. Insert the pin from the shift arm assembly into the friction wheel assembly and hold assembly in position. Refer to Figure 18. Slide the gear shaft through the left side of the housing and through the friction wheel assembly. Insert the gear shaft through the sprocket and the spacer. Make certain that the chain engages both the large and the small sprocket.
SECTION 8: TROUBLE SHOOTING GUIDE Trouble Possible Cause(s) Engine fails to start 1. Corrective Action Fuel tank empty, or stale fuel. 1. Blocked fuel line.
