Read and understand the entire Safety section before proceeding. GB - 27 NOTE: Keep housing level by adjusting skid shoes equally. 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. See SERVICE PARTS on page 37. Occasionally a foreign object may enter the auger/impeller housing and jam the auger, breaking shear bolts (Figure 28) which secure the auger to the shaft. This allows auger to turn freely on the shaft which may help prevent 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. REMOTE WHEEL LOCK (921012, 013, 020) If remote wheel lock does not lock or unlock: 1. Place unit in service position (see Service Position on page 24). 2. Loosen jam nuts on cable. Make sure the bottom jam nut is loosened enough to remove slack from cable (Figure 29). 3. Pull the cable adjuster to remove slack between the cable adjuster and the extension spring and hold the cable adjuster in position while finger tightening the top jam nut against the bracket. Do not extend the spring or engage the mechanism. 4. Tighten the bottom jam nut. 5. Check function of remote wheel lock. If wheel lock does not function properly, remove bottom cover to check cable slack. 6. Repeat steps 2 – 4 while watching cable to remove slack. 7. Check function of remote wheel lock. If wheel lock does not function properly, take the unit to Dealer for repairs. Figure 27 2 1 OS0482 1. Skid Shoe 2. Skid Shoe Hardware Figure 28 1. Auger 2. Shear Bolts OS7150 1 2 Figure 29 1.

If deflector does not stay in set position: 1. Tighten nut beneath control panel to increase pressure on deflector control (Figure 30). If deflector does not follow full range of travel: 1. Push deflector remote all the way forward. 2. Loosen adjusting nuts on cable support bracket underneath the dash panel (Figure 30). 3. To adjust the deflector lower: Slide cable down. Tighten bottom nut. 4. To adjust deflector higher: Slide cable up. Tighten top nut. 5. Check travel and repeat adjustment as necessary. DISCHARGE CHUTE CONTROL (921017, 018) If chute does not stay in position while throwing snow or if chute does not rotate freely, adjust the cable under the gear cover so the chute lock fingers engage or disengage the locking gear. If chute does not stay in position: Loosen the cable by loosening the rear adjustment nut, and then tightening the forward adjustment nut against the bracket until the lock arm engages the gear teeth (Figure 31). If chute does not rotate freely: Tighten the cable by loosening the forward adjustment nut, and then tightening the rear adjustment nut against the bracket until all cable slack is removed (Figure 31).

To adjust, loosen then retighten hardware to desired deflection drag force (Figure 32). Discharge Chute Adjusting Deflector Hardware Discharge Chute Figure 32 OS7176 DISCHARGE CHUTE (921011, 012, 014, 015, 019) If discharge chute does not stay in position while operating, tighten nut on carriage bolt at pivot point to increase tension on spring (Figure 33).

Place the speed selector on the dash in the fastest forward speed position. 3. Turn the speed selector lever straight down towards the ground as far as it will go. 4. 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. 5. Secure adjustment pivot pin with hairpin. 6. Make sure the speed selector shifts into each speed position. 7. Check forward and reverse speeds: a. Start unit. b. Shift speed selector into the first forward speed. c. Engage the traction clutch. Unit should move forward. GB - 29 GB - 30 d. Stop unit. e. Shift speed selector into first reverse speed. f. Engage the traction clutch. Unit should move backward. g. Shut off unit. 8. Adjust pivot pin on the shift rod as necessary so unit travels forward when speed selector is in first forward position and travels backward when speed selector is in first reverse position. 9. Connect the pivot pin to the speed selector arm with the hardware removed in step 1. ATTACHMENT CLUTCH/BRAKE ADJUSTMENT (Figures 35 and 36) Remove Attachment Cable Slack 1. Remove...
