SERVICE AND ADJUSTMENTS WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. SCRAPER BLADE IMPORTANT: Damage to 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. Reposition scraper blade and tighten lock nuts. 3. Ajust skid shoes. IMPORTANT: ALWAYS adjust skid shoes after adjusting scraper blade to prevent premature wear to scraper blade or damage to housing. SKID SHOES (Figure 27) IMPORTANT: Skid shoes should be adjusted as conditions require. Allow 1/8" (3 mm) between scraper blade and hard smooth surfaces. Allow 7/8" (22 mm) between scraper blade and uneven or gravel surfaces. 1. Position unit on a hard, flat, smooth, level surface. 2. Adjust skid shoes by inserting a spacer of desired thickness under center of scraper blade, loosen skid shoe hardware. 3. Slide skid shoe to flat surface. NOTICE: Be sure to keep housing level by adjusting skid shoes equally. 4. Tighten skid shoe hardware. SHEAR BOLTS (Figure 28) IMPORTANT: Use only Ariens OEM shear bolts for replacement. Use of any other type of shear bolt may result in severe damage to unit. See SERVICE PARTS on page 35. Occasionally a foreign object may enter the auger/impeller housing and jam the auger, breaking shear bolts which secure the auger to the shaft. This allows auger to turn freely on the shaft which may help prevent damage to gear case. 1 2 1. Auger 2. Shear Bolts Figure 28 For Replacement: 1.
