4. To adjust deflector higher: Slide cable up. Tighten top nut. 5. Check travel and repeat adjustment as 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 14). GB - 22 Smooth and easy rotation of properly lubricated chute with crank is obtained by adjusting pinion and chute gear teeth so they mesh together. Figure 14 1. Pinion 2. Chute Gear 3.

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. 1 2 1. Runner 2. Runner Hardware Figure 15 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 16) which secure the auger to the shaft. This allows auger to turn freely on the shaft preventing damage to gear drive. For Replacement: 1. Slide auger outward against roll pin and align hole in shaft with hole in auger (holes in shaft for roll pins and shear bolts line up). 2. Drive shear bolt through hole (if shear bolt was broken this will drive remaining part from shaft). 3. Secure shear bolt with nut. Figure 16 1. Auger 2. Shear Bolts 3. Roll Pin 1 2 3 OS0402 GB - 23 SPEED SELECTOR ADJUSTMENT SPEED SELECTOR ADJUSTMENT 1. Place unit into service position. 2. Remove hair pin from adjustment pivot pin. 3. Pull shift rod and pin out of speed selector lever. 4. Place the speed selector in the fastest reverse speed position. 5. Pull the shift rod straight up towards the control panel as far as it will go. 6. Thread the adjustment pivot pin along the shift rod until it aligns with the mating hole on the speed selector lever. Insert the pivot pin into hole. 7. Make sure the speed selector shifts into each speed position. 8. Secure adjustment pivot pin with hairpin. Figure 17 1. Shift Rod 2. Adjustment Pivot Pin 3.

Hairpin 1 2 3 4 ATTACHMENT CLUTCH/BRAKE ADJUSTMENT (Figures 18 and 19) IMPORTANT: IMPROPER ADJUSTMENT could result in unexpected movement of auger and impeller causing death or serious injury. Auger / impeller must stop within 5 seconds when Attachment Clutch/Impeller Brake lever is released. 1. Remove belt cover. 2. Check belt alignment (Figure 21). Engine sheave and attachment pulley must align vertically. Also, belt must be centered in the idler pulley. To align, move attachment pulley: a.Loosen set screws. b.Slide pulley and key to desired position. c.Tighten set screws. 3. Install belt cover. 4. Adjust cable slack. IMPORTANT: The belt cover must be installed and the clutch cable must be slack when the lever is disengaged. a.With clutch lever disengaged, loosen jam nut on cable adjuster. b.Turn adjuster body to remove all slack from the cable. Do not stretch spring or move lower clutch arm. c.Turn back the adjuster body 5 turns (approximately 1/4 in. or 6 mm). Finger tighten jam nut. d.Hold adjuster body with pliers and tighten jam nut with wrench. 5. Check spring length. a.Measure the length of the clutch cable spring. b.Engage and hold the attachment clutch lever. c.Measure the length of the spring again. The spring should be 7/16 –11/16 in. (11.1–17.5 mm) longer when the lever is engaged. GB - 24 6. 6. NOTE: Approximately 1/8 in. (3 mm) movement of the idler will change spring extension by 1/8 in. (3 mm). a.Loosen the idler adjustment nut. b.To increase spring extension, move idler towards belt (Figure 21). c.To decrease spring extension, move idler away from belt. d.Tighten idler adjustment nut. 7. Place unit in service position. Remove bottom cover by removing four cap screws. 8. Check brake. When the clutch lever is disengaged, the brake must contact attachment belt. When the clutch lever is engaged, the brake must be more than 1/16 in. (1.6 mm) away from the belt (Figure 19). 9. Repeat steps 4 – 7...
