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.
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 19) 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.
SPEED SELECTOR ADJUSTMENT
To adjust (Figure 20):
1. Place unit into service position.
2. Remove hair pin from adjustment pivot pin.
3. Pull shift rod and pin out of speed selector
lever.
4. Place the speed selector in the fastest
reverse speed position.
5. Pull the shift rod straight up towards the
control panel as far as it will go.
6. Thread the adjustment pivot pin along the
shift rod until it aligns with the mating hole
on the speed selector lever. Insert the
pivot pin into hole.
7. Make sure the speed selector shifts into
each speed position.
8. Secure adjustment pivot pin with hairpin.
