Shave blade changing or adjustment
If the wheels, shave blade and feed screw do not contact the surface at the same time, the shave blade should
be adjusted and/or the rubber blades need to be changed.
• Place the snow blower on a level surface. The wheels, shave blade and the feed screw should all make
contact with the surface at the same time.
• If the shave blade is too high, snow will be discharged out the back, under the blower.
• If the shave blade is too low, it will wear out prematurely and forward propulsion will be adversely affected.
Adjustment
1. Empty the fuel tank when the engine is cold. Do the work outside and collect the fuel in an appropriate
container. If the fuel is not to be reused, deposit it at the most appropriate recycling centre.
2. Tilt the blower forward so that
the wheels are off the ground and
the blower rests on its chassis.
3. Loosen the 4 screws and adjust
the shave blade to the desired
position.
4. Re-tighten the screws securely.
Note: If the blower is tipped back so that the handle touches the ground, there is a risk that engine oil will leak
into the engine’s combustion chamber and cause starting problems. If this should occur, remove the spark plug
and clean it thoroughly. Pull the starter handle several times with the spark plug removed in order to remove any
excess oil. Please remember to check the oil level again and add oil if needed. Replace the spark plug and start
the engine, which will initially produce smoke in the exhaust. This is completely normal.
Replacement
1. Empty the fuel tank when the engine is cold. Do the work outside and collect the fuel in an appropriate
container. If the fuel is not to be reused, deposit it at the most appropriate recycling centre.
2. Tilt the blower forward so that the wheels are off the ground and the blower rests on its chassis.
3. Loosen the 4 screws and remove the shave blade.
4. Install the new shave blade so that the wheels, shave blade and the feed screw make contact with an even
level surface at the same time.
5. Retighten the screws securely.
Changing the rubber feed screw blade
1. Loosen the 4 retaining screws and feed screw.
2. Replace with a new blade and tighten the retaining bolts securely.
