WARNING: AVOID INJURY. Read
and understand the entire Safety
section before proceeding.
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 skid shoes to fully raised position
(housing closest to ground).
3. Reposition scraper blade flush with skid
shoes and tighten lock nuts.
SKID SHOES
(Figure 13)
Skid shoes should be adjusted as conditions
require.
1. Position unit on a hard, flat, smooth level
surface.
2. Adjust skid shoes by inserting a spacer
of desired thickness under center of
scraper blade, loosen skid shoe
hardware, slide skid shoes 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 skid
shoes equally.

SERVICE AND ADJUSTMENTS

SHEAR BOLTS
(Figure 14)
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 which secure the auger
to the shaft. This allows auger to turn freely
on the shaft which may help prevent damage
to gear case and its components.
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.
NOTE: DO NOT overtighten the shear bolt.
Tighten shear bolt to 5.8 – 12.2 lbf-ft
(7.9 – 16.5 N•m).
