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.

require (Figure 19).
1. Position unit on a hard, flat, smooth level
surface.
2. Adjust runners by inserting a spacer of
desired thickness under center of

slide runners to flat surface. Allow 1/8 in.
(3 mm) between scraper blade and hard
smooth surfaces. Allow 1-1/4 in.

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 32.
Occasionally a foreign object may enter the
auger/impeller housing and jam the auger,
breaking shear bolts (Figure 20) which
secure the auger to the shaft. This allows
auger to turn freely on the shaft preventing
damage to gear drive.

For Replacement:

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.
