Do NOT operate the snow thrower without first reading the Tecumseh Engines operator’s manual for instructions regarding proper fuel and engine oil.
Discharge Chute Shave Plate The pitch of the discharge chute controls the angle at which the snow is thrown. Loosen the wing knob on the side of the discharge chute before pivoting the discharge chute upward or downward. Retighten the knob once the desired position has been achieved. The shave plate scrapes along the pavement as the snow thrower is propelled, allowing the snow close to the pavement’s surface to be discharged.
• • After clearing snow, allow the engine to run for an extra few minutes before storing to help dry any moisture on the engine. To stop the engine: Turn the ignition key counterclockwise to the OFF position. Refer to Ignition Key on page 7. Remove the key form the snow thrower’s ignition switch before storing. IMPORTANT: Keep the ignition key in a safe place. The engine can not be started without it. • • Wipe all the snow and any moisture which has formed, from the unit.
Shave Plate • To check the adjustment of the shave plate, place the unit on a level surface. The wheels, shave plate and augers should all contact the level surface. Note that if the shave plate is adjusted too high, snow may blow under the housing. If the shave plate wears out excessively, or the unit will not selfpropel, the shave plate may be adjusted too low. NOTE: On new units or units with a new shave plate installed, the augers may be slightly off the ground.
• Replacing the Auger’s Rubber Paddles Reattach the belt cover with the five hex screws removed earlier. The snow thrower auger’s rubber paddles are subject to wear and should be replaced if any signs of excessive wear is present. Replacing the Shave Plate The shave plate is subject to wear and should be checked periodically. There are two wearing edges and the shave plate can be reversed after one side wears out. To replace (or reverse) the shave plate, proceed as follows:.
