Runners
Runners should be adjusted as conditions require.
Raising or lowering runners controls distance scraper
blade (auger/impeller housing) is held above surface
being cleared.
1. Position unit on a hard, flat smooth level surface.
2. Adjust runners by inserting a spacer of desired
thickness under center of scraper blade, loosen
runner hardware, slide runners to flat surface
(Figure 12). Allow 1/8" (3 mm) between scraper
blade and hard smooth surface. Allow 1-1/4"
(30 mm) minimum between scraper blade and
uneven surface(s).
3. Retighten hardware.
NOTE: Keep housing level by adjusting runners
equally. Uneven runners make unit difficult to steer and
results in uneven clearing.

Scraper Blade
IMPORTANT: Damage to auger/impeller housing will
result if blade wears down too far.
Scraper blade is adjustable to compensate for wear.
To adjust scraper blade:
1. Tip unit back onto handlebar. Support the housing
and loosen scraper blade nuts. With runners
adjusted to their full up position, reposition scraper
blade down, flush with runners. Tighten lock nuts.
Readjust runners if necessary.
Chute Crank
If chute does not stay in position while operating,
tighten nut on carriage bolt at pivot point to increase
tension on spring (Figure 13).
Smooth and easy rotation of properly lubricated chute
with crank is obtained by adjusting pinion and chute
gear teeth so they mesh together.
