SERVICE AND ADJUSTMENTS

WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding.

RUNNERS

Runners should be adjusted as conditions require (Figure 19).

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.

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 20) 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.

HANDLEBAR HEIGHT

CAUTION: AVOID INJURY. Adjust the attachment clutch, speed selector and traction clutch after changing the handlebar height. See Attachment Clutch/Brake Adjustment on page 25, Speed Selector Adjustment on page 25 and Traction Drive Clutch Adjustment on page 26.

To raise or lower the handlebar:

1.Remove hair pin holding chute rod to control assembly.

2.Place unit in service position (see Service Position on page 19).

3.Remove bottom cover.

4.Remove top mounting bolts from the handlebars and adjust the handlebar up or down as needed until the handlebar mounting holes align with holes in unit frame.

5.Secure handlebar to frame with hardware removed in step 4 using the different hardware locations shown in Figure 21.
