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. DANGER! 2. DANGER! Danger! Danger! ROTATING PARTS! ONLY use clean-out tool to clear blockages. NEVER use your hands. High speed impeller rotates below discharge opening. Wait for all moving parts to stop before removing clogs or servicing. ONLY use clean-out tool to clear blockages. NEVER use your hands. Never direct discharge towards persons or property that may be injured or damaged by thrown objects. 3. DANGER! Keep people away from unit while operating.
EMISSION CONTROL SYSTEM This equipment and/or its engine may include exhaust and evaporative emissions control system components required to meet U.S. Environmental Protection Agency (EPA) and/or California Air Resources Board (CARB) regulations. Tampering with emission controls and components by unauthorized personnel may result in severe fines or penalties. Emission controls and components can only be adjusted by an Ariens Company dealer or an authorized engine manufacturer's service center.
DO NOT overload the machine capacity by attempting to operate or to clear snow at too fast a rate. Slow down and turn corners slowly. Do not operate in reverse unless absolutely necessary. ALWAYS back up slowly. Always look down and behind before and while backing. Disengage attachment drive when traveling from one work area to another. Abnormal Vibrations are a warning of trouble. Striking a foreign object can damage unit. Immediately stop unit and engine. Remove key and wait for all moving parts to stop.

SERVICE AND ADJUSTMENTS SHEAR BOLTS WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. (Figure 23) 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. Adjust skid shoes.
MANUAL DISCHARGE CHUTE DEFLECTOR (920013) (Figure 24) 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 26). 3. To adjust the deflector lower: Loosen bottom adjustment nut and tighten top adjustment nut.
SPEED SELECTOR ADJUSTMENT 3 (Figure 28) 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 31 and 32) 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 31). 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 31 • 1. Attachment Clutch Cable 2. Cable Adjustment Barrel 3. Jam Nut Figure 29 • 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 33) 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 29.
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.
TRACTION DRIVE BELT REPLACEMENT (Figures 38) NOTE: Housing and frame must be tipped apart and attachment drive belt removed from engine sheave in order to change traction drive belt. CAUTION: Always support Sno-Thro frame and blower housing when loosening the cap screws holding them together. Never loosen cap screws while unit is in service position. 1. Remove attachment drive belt (See Remove Attachment Drive Belt on page 29). 2. Remove swing gate spacer. 3.
4 STORAGE 8 WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. 7 SHORT TERM 3 IMPORTANT: NEVER spray unit with high pressure water or store unit outdoors. Run with attachment clutch engaged a few minutes after each use to free unit of any loose or melting snow. Close fuel shut-off valve. Inspect unit for visible signs of wear, breakage or damage. Keep all nuts, bolts and screws properly tightened and know unit is in safe working condition.
Add Fuel Stabilizer 1. Turn the fuel valve off while engine is running and allow the engine to run until it stops. Turn engine OFF when it begins surging to avoid engine damage. 2. Add fuel stabilizer, following the manufacturer’s instructions. 3. Turn fuel valve on after adding fuel stabilizer. 4. Re-start engine. 5. Run the engine outdoors for 1 minutes to be sure that treated gasoline has replaced the untreated gasoline in the carburetor. 6. Slow the engine to an idle speed. 7. Repeat step 1 above.
TROUBLESHOOTING PROBLEM Engine stops. PROBABLE CAUSE 1. Out of fuel. 2. Fuel shut-off valve closed. 3. Mechanical jam in blower rake or impeller. CORRECTION 1. Fill fuel tank (see FILLING FUEL TANK on page 19). 2. Open fuel shut-off valve. 4. Polluted fuel supply. 5. Faulty spark plug. 6. Plugged fuel cap vent. 3. Turn off engine, remove key, and wait for all moving parts to stop. Check for and remove obstruction and repair before restart. 4. Replace with clean fuel. 5. Replace or clean spark plug. 6.
