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 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.
