Keep hands and feet away. Loose clothing, long hair or scarves can get caught in rotating parts and cause death or serious injury. IMPORTANT: Use only Ariens Shear Bolts for replacement. Use of any other type of shear bolt may result in severe damage to the unit. Occasionally a foreign object may enter the auger/ impeller housing and jam the auger, breaking Shear Bolts which secure the auger to the shaft (Figure 6). This allows auger to turn freely on the shaft preventing damage to the gear drive. 4 - 14 OS0401 1. Auger 2. Roll Pin 3. Shear Bolt(s) 4. Nut(s) 2 3 4 Figure 6 1 1. Auger 2. Roll Pin 3. Shear Bolt(s) 4. Nut(s) 2 3 4 Figure 6 1 For Replacement: 1. Slide auger outward against roll pin and align hole in shaft with hole in auger. The holes in the shaft for the roll pins and Shear Bolts line up. 2. Drive Shear Bolt through hole (if Shear Bolt was broken this will drive the remaining part from shaft). 3. Secure Shear Bolt with nut. 4. The Shear Bolts should not be overtightened to collapse the auger center tube to the auger drive shaft. 4.11 TIRE PRESSURE Maintain the unit tire pressure at a maximum of 20 PSI (138 kPa). 4.12 ADJUSTMENTS WARNING: ACCIDENTAL ENGINE START UP can cause death or serious injury. ALWAYS stop engine, remove key, wait for moving parts to stop and remove wire from spark plug before adjusting or servicing. Discharge Chute Deflector To adjust the drag force, loosen or tighten the two bolts to accomplish the desired drag. Runners Runners should be adjusted as conditions require. Raising or lowering runners controls distance scraper blade (auger/impeller housing) is held above surface being cleared. 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 (Figure 7). Allow 1/8" (3 mm) between scraper blade and hard smooth surface. Allow 1-1/4" (30 mm) minimum between scraper blade and uneven surface(s). 3. Retighten hardware. NOTE: Keep housing level by adjusting runners equally. Uneven runners make unit difficult to steer and results in uneven clearing. 1 2 1. Runner 2. Runner Hardware OS0480 Figure 7 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 the housing and loosen scraper blade nuts. With runners adjusted to their full up position, reposition scraper blade down, flush with runners. Tighten lock nuts. Readjust runners if necessary. Discharge Chute If chute does not stay in position while operating, tighten nut on carriage bolt at pivot point to increase tension on spring (Figure 8). Smooth and easy rotation of properly lubricated chute with crank (without binding) is obtained by adjusting pinion and flat gear teeth so they mesh together. Adjust, using adjustment slots in pinion bracket which is secured to chute strap. 4 - 15 Attachment Clutch/Impeller Brake 1. Carriage Bolt 2. Spring 3. Pinion Bracket 4. Pinion 5. Chute Strap 6.

To adjust Attachment Clutch/Impeller Brake: 1. Remove belt cover. When clutch is disengaged there should be a slight amount of slack in the attachment cable to allow for brake wear. 2. Clutch cable spring should extend approximately 3/8" (9,5mm) when clutch is engaged but allow clutch arm (at lower end) to return to its maximum down position when clutch is disengaged. To increase spring extension. loosen adjustment hardware (Figure 5) and move the attachment idler toward the belt. Approximately 1/8" (3,2 mm) movement of the idler will increase spring extension by 1/8" (3,2 mm). 3. To check impeller brake, tip unit forward onto auger/impeller housing. Remove bottom cover by removing four cap screws. 4. Measure distance between impeller brake shoe pad and belt with attachment clutch engaged (Figure 9). Impeller brake shoe should be 1/16" (1.6 mm) minimum from belt. When attachment clutch is disengaged, brake must contact belt. I...
