1. Scraper
2. Mounting screws
3. Auger blades
Note: The auger blades and scraper should be higher
above the pavement if the pavement surfaces on which
the snowthrower will be used are cracked, rough or
uneven.
5. Check the scraper blade adjustment. To adjust scraper,
loosen (5) mounting screws (Fig. 18), pull scraper all
the way down, and retighten screws.
6. When scraper is adjusted correctly and is supported
above level surface, move the skids down to sit flat on
the ground and tighten the (4) flange nuts securing
both skids to the auger side plates (Fig. 17). Skids will
now support the auger blades and scraper above the
ground.
For Gravel Surfaces
For gravel or crushed rock surfaces, adjust the skids to
prevent picking up rocks.
1. Pull wire off spark plug and make sure wire does not
contact plug accidentally.
2. Loosen the (4) flange nuts securing both skids to auger
side plates (Fig. 17). Next, slide skids down as far as
possible so auger will be supported as far from the
level surface as skid adjustment allows; then tighten
flange nuts.
