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 25).
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 35.
Occasionally a foreign object may enter the
auger/impeller housing and jam the auger,
breaking shear bolts (Figure 26) which
secure the auger to the shaft. This allows
auger to turn freely on the shaft preventing
damage to gear drive.
For Replacement:
1. Align shear bolt holes in auger with
shear bolt holes in the shaft.
2. Drive shear bolt through hole (if shear
bolt was broken this will drive remaining
part from shaft).
3. Secure shear bolt with nut.
Remote Wheel Lock (921002)
If remote wheel lock does not lock or unlock:
1. Place unit in service position (see
Service Position on page 21).
2. Loosen jam nuts on cable. Make sure
the bottom jam nut is loosened enough
to remove slack from cable (Figure 27).
3. Pull the cable adjuster to remove slack
between the cable adjuster and the
extension spring and hold the cable
adjuster in position while finger
tightening the top jam nut against the
bracket. Do not extend the spring or
engage the mechanism.
4. Tighten the bottom jam nut.
