UNAUTHORIZED REPLACEMENT PARTS Serial Number Label Use only Ariens replacement parts. The replacement of any part on this vehicle with anything other than an Ariens authorized replacement part may adversely affect the performance, durability, or safety of this unit and may void the warranty. Ariens disclaims liability for any claims or damages, whether warranty, property damage, personal injury or death arising out of the use of unauthorized replacement parts.
SAFETY PRACTICES AND LAWS WARNING: To avoid injury to hands and feet, always disengage clutches, shut off engine, and wait for all movement to stop before unclogging or working on snow thrower. Hand contact with the rotating impeller is the most common cause of injury associated with snow throwers. Never use your hand to clean out the discharge chute. Keep hands and feet away from auger and impeller. SAFETY ALERTS Look for these symbols to point out important safety precautions.
1. WARNING! 3. DANGER! Read Owner/Operator Manual. OL1801 OS2080 Keep people away from unit while operating. Keep children out of work area and under watchful care of a responsible adult.

Never use your hand to clean out the discharge chute.
Discharge Chute Scraper Blade Discharge chute rotates 205°. ALWAYS position discharge chute in safe direction and angle, away from operator and bystanders, before starting engine. The scraper blade allows better contact with the surface being cleared. It also prevents damage to the housing from wear. Discharge Chute Crank IMPORTANT: If chute does not stay in set position, adjust as directed in SERVICE AND ADJUSTMENTS on page 19, or repair before operation.
3. Turn fuel valve on after adding fuel stabilizer. 4. Re-start engine. 5.

MAINTENANCE Ariens dealers will provide any service or adjustments which may be required to keep your unit operating at peak efficiency. Should engine service be required, contact an Ariens dealer or an authorized engine manufacturer's service center. The chart below shows the recommended maintenance schedule that should be performed on a regular basis. More frequent service may be required. MAINTENANCE SCHEDULE WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding.
CHECK CLUTCH OPERATION CHECK AUGER GEARCASE Auger / impeller must stop within 5 seconds when attachment clutch/impeller brake lever is released. Wheels must stop quickly when traction drive clutch lever is released. If clutches do not engage or disengage properly, adjust or repair before operation (see Attachment Clutch/Brake Adjustment on page 24 and Traction Drive Clutch Adjustment on page 26).
GENERAL LUBRICATION Grease (Figure 12) Oil 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 Ariens Hi-Temp Grease or equivalent to the lubrication fittings. See SERVICE PARTS on page 28. The unit should be lubricated (Figure 12) at beginning of season or every 25 operating hours.
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. 1 DISCHARGE CHUTE DEFLECTOR 2 1. Skid Shoe 2. Skid Shoe Hardware OS0482 (Figure 15) Deflector must stay in selected position while throwing snow. To adjust, loosen then retighten the wing knob to desired tension.
DISCHARGE CHUTE (Figure 16) If discharge chute does not stay in position while operating, tighten nut on carriage bolt at pivot point to increase tension on spring. 1 e. Shift speed selector into 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 necessary so unit travels forward when speed selector is in first forward position and travels backward when speed selector is in first reverse position. 8.
4. Remove spring pin from chute crank and separate. 5. Remove belt finger by removing cap screws mounting belt finger to engine (Figure 19 or 20). 6. Remove attachment drive belt from engine sheave (it may be necessary to turn engine sheave using recoil starter handle). IMPORTANT: With the clutch lever engaged, the belt finger located opposite the belt idler must be less than 1/8 in.

With the attachment clutch disengaged, check the attachment idler arm position here.
2. Adjust cable length (Figure 26). a. Loosen jam nut on cable. b. To increase spring extension, adjust barrel down the cable and tighten jam nut. c. To decrease spring extension, adjust barrel up the cable and tighten jam nut. Roller should be 1/2 – 7/8 in. (12.7 – 22.2 mm) from the frame when the attachment clutch is engaged. Check Attachment Brake Figure 25 OS8080 Adjust the Attachment Clutch Cable Spring Extension (Figure 26) 1. Check the attachment clutch cable spring extension.
Check Belt Finger Clearance (Figure 28) 1. With clutch lever engaged, the belt finger located opposite the belt idler must be less than 1/8 in. (3.2 mm) from belt, but not touching the belt. To adjust belt finger, loosen the bolts and move the finger to the proper position. Tighten the bolts and recheck the belt finger clearance. 2. Replace the belt cover and tighten hardware. Check belt finger clearance here. With the attachment clutch engaged, there should be less than 1/8 in. (3.
