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 11).
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.
Occasionally a foreign object may enter the
auger/impeller housing and jam the auger, breaking
shear bolts (Figure 12) 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.
NOTE: DO NOT overtighten the shear bolt. Tighten
shear bolt to 5.8 – 12.2 lbf-ft (7.9 – 16.5 N•m).
DISCHARGE CHUTE DEFLECTOR
Deflector must stay in selected position while throwing
snow.
To adjust, loosen then retighten hardware to desired
deflector drag force (Figure 13).
