SERVICE AND ADJUSTMENTS

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.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.
