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. OS2080 Keep people away from unit while operating. Keep children out of work area and under watchful care of a responsible adult. OL4370 Never direct discharge towards persons or property that may be injured or damaged by thrown objects. OL0910 Stop engine, remove key, read manual before making any repairs or adjustments.

OPERATION WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. 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. Keep hands and feet away from auger and impeller. IMPORTANT: If the belt squeals when the attachment clutch lever is engaged, the impeller may be frozen in the auger housing.
Speed Selector Choke Control Position the Speed Selector in the appropriate speed notch to control forward and reverse travel. (Figure 12) 1. Choke Closed position: chokes off air to engine for easier start. 2. Choke Open position: allows for normal operation. IMPORTANT: Gradually open choke after engine starts. 6 1 2 1 920013 Forward: 2 (6) Fastest (1) Slowest 1 Reverse: RUN START 920014 (1) Slow (2) Fast 2 1 IMPORTANT: DO NOT change motion from forward to reverse with clutch engaged.
Snow Clean-Out Tool Discharge Chute (Figure 13) Discharge chute rotates 205°. ALWAYS position discharge chute in safe direction and angle, away from operator and bystanders, before starting engine. WARNING: 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.
Scraper Blade To add fuel to fuel tank: The scraper blade allows the back of the housing to keep better contact with the surface being cleared. It also prevents damage to the housing from normal use. 1. ALWAYS place unit in open or wellventilated area. 2. Stop engine and allow to cool. 3. Clean Fuel Cap and surrounding area to prevent dirt from entering Fuel Tank. 4. Remove fuel caps. IMPORTANT: Refer to Engine Manual for correct type and grade of fuel. 5. Fill fuel tank to the bottom of filler neck.
If clutches do not engage or disengage properly, adjust or repair before operation (see Attachment Clutch/Brake Adjustment on page 25 and Attachment Drive Belt Replacement on page 27). 4. Check Axle Lock Pins Use the axle lock pins to lock or unlock the wheels. Lock both wheels to increase traction; unlock one wheel to allow for easier turning of the unit. 5. Check Skid Shoes Check and adjust skid shoes (Skid Shoes on page 23). Allow 1/8 in. (3 mm) between scraper blade and hard, smooth surface(s).
8. If engine is cold, apply choke. A warm engine requires less choking than a cold engine. See Engine Manual for detailed instructions. 9. 920014 - Set throttle to proper starting position 10. Press starter button on engine until engine starts. IMPORTANT: DO NOT operate starter more than 15 seconds per minute, as overheating and damage can occur. (If engine does not start, refer to TROUBLESHOOTING on page 31.) 11. Adjust choke as needed. 12. Disconnect power cord from outlet, then starter. 13.

NOTE: Apply Ariens Hi-Temp Grease or equivalent to the lubrication fittings. See SERVICE PARTS on page 31. Sno-Thro should be lubricated (Figure 17) at beginning of season or every 25 operating hours. Auger Shaft NOTE: To grease auger shaft, remove shear bolt nuts, and shear bolts.
SERVICE AND ADJUSTMENTS SHEAR BOLTS WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. (Figure 19) SCRAPER BLADE IMPORTANT: Damage to 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. Reposition scraper blade and tighten lock nuts. 3. Ajust skid shoes.
MANUAL DISCHARGE CHUTE DEFLECTOR (920013) (Figure 20) Deflector must stay in selected position while throwing snow. To adjust, loosen then retighten the wing knob to desired tension. If deflector does not follow full range of travel: 1. Push deflector remote all the way forward. 2. Loosen adjusting nuts on remote deflector cable attached to the chute deflector (Figure 22). 3. To adjust the deflector lower: Loosen bottom adjustment nut and tighten top adjustment nut.
SPEED SELECTOR ADJUSTMENT 3 (Figure 24) To adjust: 1. Disconnect adjustment pivot pin from speed selector arm. Save hardware for reinstallation. 2. Place the speed selector on dash panel in the fastest forward speed position. 3. Turn the speed selector arm 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 arm, and then turn it up the shift rod 7 turns. Insert the pivot pin into hole. 5.
Check Attachment Idler Arm Roller Clearance (Figure 27 and 28) 1. Place the unit into the service position. Remove the bottom cover. 2. With the attachment clutch lever engaged, check the clearance between the frame and plastic roller on the lower end of the attachment idler arm (Figure 27). 1 Roller should be 1/2 – 7/8 in. (12.7 – 22.2 mm) from the frame when the attachment clutch is engaged. 2 3 Figure 27 • 1. Attachment Clutch Cable 2. Cable Adjustment Barrel 3. Jam Nut Figure 25 • OS8255 4.
Check Attachment Brake Check belt finger clearance here. With the attachment clutch engaged, there should be less than 1/8 in. (3,2 mm) clearance between the belt and the belt finger. The belt finger should not touch the belt. (Figure 29) 1. With the clutch lever disengaged, brake pad must contact attachment belt. With clutch lever engaged, brake pad must be more than 1/16 in. (1.6 mm) from belt. If there is more than 1/16 in. (1.6 mm) gap, go to Check Belt Finger Clearance on page 27.
IMPORTANT: To avoid bending bottom cover, when tipping unit apart, support handlebars firmly or tip unit up on housing and remove bottom cover by removing six cap screws before separating unit. 8. Support Sno-Thro frame and housing. 9. Remove hex bolts securing housing to frame (two on each side). Tip housing and frame apart on pivot pin. 10. Separate housing from unit. 11. Remove attachment drive belt from attachment pulley. 1 3 6. Replace chute crank and secure with hairpin.
