DISCHARGE CHUTE DEFLECTOR
To adjust, loosen then retighten hardware to desired
deflector drag force.
DISCHARGE CHUTE
If chute does not stay in position while operating,
tighten nut on carriage bolt at pivot point to increase
tension on spring.
Smooth and easy rotation of properly lubricated chute
with crank is obtained by adjusting pinion and flat gear
teeth so they mesh together.
Adjust, using adjustment slots in pinion bracket which
is secured to chute strap.
The chute bracket and gear strap are also slotted for
vertical adjustment of the discharge chute. Loosen
mounting nut and move discharge chute up or down so
that chute ring is approximately centered between
retainer clip and lower ring. Retighten.
RUNNERS
Runners should be adjusted as conditions require.
Raising or lowering runners controls distance scraper
blade (Sno-Thro 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
hardware, slide runners to flat surface (Figure
17). Allow 1/8" (3mm) between scraper blade and
hard smooth surface. Allow 1 1/4" (30mm)
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 Sno-Thro 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 housing
and loosen nuts retaining blade.
2. With runners adjusted to their full up position,
reposition scraper blade down, flush with runners,
and tighten lock nuts.
