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.
