2. Add lubricant if required. Allow oil to drain to level of plug and replace plug. IMPORTANT: Use only Ariens special gear lubricant L-2 (Part Number 00008000). Gearcase filler plug may require an application of thread sealant with repeated servicing. 2 OS1830 Figure 12 GENERAL LUBRICATION IMPORTANT: Wipe each fitting clean before and after lubrication. Do not wipe gearcase filler plug; wiping the gearcase filler plug may remove thread sealant and cause leaks. IMPORTANT: DO NOT allow grease or oil to get on friction disc, friction plate or belts. NOTE: Apply Stens Mix Hi-Temp Grease or equivalent to the lubrication fittings. See SERVICE PARTS on page 24. Sno-Thro should be lubricated (Figure 13) at beginning of season or every 25 operating hours. Auger Shaft NOTE: To grease auger shaft, remove shear bolt nuts, and shear bolts. Turn auger on shaft while applying grease at zerk fittings. Replace shear bolts per instructions in SERVICE AND ADJUSTMENTS on page 18. OS1373 Grease Oil Figure 13 1. Auger Gearcase 2. Filler Plug GB - 17 SERVICE AND ADJUSTMENTS SERVICE AND ADJUSTMENTS WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. RUNNERS Runners should be adjusted as conditions require (Figure 14). 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. 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. 2 1 1.Runner 2.Runner Hardware OS0486 Figure 14 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 15) which secure the auger to the shaft. This allows auger to turn freely on the shaft preventing damage to gear drive. Figure 15 1. Auger 2. Shear Bolts 1 2 OS6780 2 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. DISCHARGE CHUTE DEFLECTOR Deflector must stay in selected position while throwing snow. To adjust, loosen then retighten hardware to desired deflector drag force (Figure 16).

Disconnect pivot pin from the speed selector arm. Save the hardware for reinstallation. 2. Place the speed selector lever in the fastest forward speed position. 3. Push the speed selector arm straight down towards the ground as far as it will go. 4. Thread the adjustment pivot pin up or down the shift rod until it aligns with the mating hole in the speed selector arm. 5. Connect the pivot pin to the speed selector arm with the hardware removed in step 1. 6. 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. d. Stop unit. e. Shift speed selector into the first reverse speed. f. Engage the traction clutch. Unit should move backward. g. Shut off unit. 7. Adjust pivot pin on the shift rod as needed so unit travels forward when speed selector lever is in first forward position and backward when speed selector is in first reverse position. 8. Connect the pivot pin to the speed selector arm with the hardware removed in step 1. Figure 18 1. Shift Rod 2. Pivot Pin 3. Speed Selector Arm 4.

Shut off engine, remove key, disconnect spark plug wire and allow unit to cool completely. 2. Remove two screws securing belt cover to unit and remove belt cover. 3. Remove spring pin from chute crank and separate (932041, 042, 141, 509, 510, 511). 4. Remove belt finger by removing cap screw mounting belt finger to engine (Figure 20). 5. Remove attachment drive belt from engine sheave (it may be necessary to turn engine sheave using recoil starter handle).
