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 24).
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 29.
Occasionally a foreign object may enter the
auger/impeller housing and jam the auger, breaking
shear bolts (Figure 25) 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 18).
2. Loosen jam nuts on cable. Make sure the bottom
jam nut is loosened enough to remove slack from
cable (Figure 26).
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.
5. Check function of remote wheel lock. If wheel
lock does not function properly, remove bottom
cover to check cable slack.
6. Repeat steps 2 – 4 while watching cable to
remove slack.
7. Check function of remote wheel lock. If wheel
lock does not function properly, take the unit to
Dealer for repairs.
