DISCHARGE CHUTE DEFLECTOR
Deflector must stay in selected position while
throwing snow.
To adjust, loosen then retighten hardware to
desired deflector drag force (Figure 11).
DISCHARGE CHUTE
If chute does not stay in position while
operating, tighten nut on carriage bolt at pivot
point to increase tension on spring (Figure 12).
RUNNERS
Runners should be adjusted as conditions
require (Figure 13).
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. Allow 1/8 in.
(3 mm) between scraper blade and hard
smooth surfaces. Allow 1-1/4 in. (30 mm)
between scraper blade and uneven or
gravel surfaces. Retighten hardware.
NOTE: Keep housing level by adjusting
runners equally.
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
housing and loosen nuts retaining blade.
2. Adjust runners to fully raised position
(housing closest to ground).
3. Reposition scraper blade flush with
runners and tighten lock nuts.
SHEAR BOLTS
IMPORTANT: Use only Ariens shear bolts for
replacement. Use of any other type of shear
bolt may result in severe damage to unit.
Occasionally a foreign object may enter the
auger/impeller housing and jam the auger,
breaking shear bolts (Figure 14) which secure
the auger to the shaft. This allows auger to
turn freely on the shaft preventing damage to
gear drive.
For Replacement:
1. Slide auger outward against roll pin and
align hole in shaft with hole in auger
(holes in shaft for roll pins and shear bolts
line up).
