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. Reposition scraper blade and tighten lock nuts. 3. Adjust 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 19) Skid Shoes should be adjusted as conditions require. 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, slide skid shoes to flat surface. 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. Retighten hardware. NOTE: Keep housing level by adjusting skid shoes equally. SHEAR BOLTS (Figure 20) 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 31. 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 drive. 1 2 1. Auger 2. Shear Bolts Figure 20 OS7150 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. NOTE: DO NOT overtighten the shear bolt. Tighten shear bolt to 5.8 - 12.2 lbf-ft (7.9 - 16.5 N•m). 2 1 1. Skid Shoes 2. Skid Shoe Hardware Figure 19 OS0483 EN - 23
