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. Reposition scraper blade and tighten
lock nuts.
3. Adjust skid shoes.
IMPORTANT: ALWAYS adjust skid shoes
after adjusting scraper blade to prevent
premature wear to scraper blade or damage
to housing.
SKID SHOES
(Figure 19)
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" (3 mm) between
scraper blade and hard smooth
surfaces. Allow 7/8" (22 mm) between
scraper blade and uneven or gravel
surfaces. Retighten hardware.
NOTICE: Keep housing level by adjusting
skid shoes equally.

SHEAR BOLTS
(Figure 20)
IMPORTANT: Use only Ariens OEM 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 which secure the auger
to the shaft. This allows auger to turn freely
on the shaft which may help prevent damage
to gear drive.

bolt hole in the shaft.

NOTICE: DO NOT overtighten the shear bolt.
Tighten shear bolt to 5.8 – 12.2 lbf-ft (7.9 –
