NOTE: Keep housing level by adjusting

runners equally.

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 16) which secure

the auger to the shaft. This allows auger to

turn freely on the shaft preventing damage to

gear drive.

For Replacement:

1. Slide auger outward against roll pin and

align hole in shaft with hole in auger

(holes in shaft for roll pins and shear bolts

line up).

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 17):

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.
