4. Replace the cover plate and secure in
position with the two screws removed in
step 1.
NOTE: Make sure the wire harness does not
get pinched between the cover plate and the
auger housing.
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.
RUNNERS
Runners should be adjusted as conditions
require (Figure 23).
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.
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. See
SERVICE PARTS on page 37.
Occasionally a foreign object may enter the
auger/impeller housing and jam the auger,
breaking shear bolts (Figure 24) which
secure the auger to the shaft. This allows
auger to turn freely on the shaft which may
help prevent damage to gear drive.
