It is recommended that the belt(s) be replaced by a qualified service center. NOTE: It is recommended that both the auger and traction drive belt be replaced at the same time. The V-belts on your snow thrower are of special con struc tion and should be replaced by original equipment man u fac tur er (OEM) belts avail able from your nearest dealer. Using other than OEM belts can cause personal injury or damage to the snow thrower. WARNING: Belt replacement requires separation of the snow thrower. While separating the auger housing from the frame assembly, it is important that an assistant stand in the operating po si tion and hold the snow thrower han dles. Serious personal injury and/ or damage to the unit could occur if the snow thrower should fall during the belt chang ing process. HINT: Insert a 3/8" drive ratchet (in the “ON” position) into the square hole in idler arm and rotate ratchet clockwise to relieve tension. 8. With tension relieved on idler, install new traction drive belt around pulleys and inside belt keepers. 9. Place auger belt around and inside the groove of auger pulley only. 10. While your assistant slowly raises handles to rejoin the auger hous ing and frame assembly, pull up on the auger belt and squeeze sides together above pulley so belt is fully seated in groove of pulley. 11. Move idler arm so it does not hit impeller pulley as you bring snow thrower completely together and check carefully for proper routing of belts. If auger belt has become dislodged from the pulley (by catching the idler arm bracket while bringing snow thrower together), separate the snow thrower and re peat step 12. Belt must be fully seated in pulley groove when bring ing the snow thrower together. 12. Install the two (2) hex bolts and tighten securely. 13. INSTALL ENGINE PULLEY - Place belt in pulley groove and slide pulley on crankshaft. Install flat washer and bolt and tighten securely (30-35 ft. lbs. torque). Make sure belt is inside belt keeper. 14. INSTALL BELT COVER and two (2) screws. Tighten securely. 15. INSTALL DISCHARGE CHUTE – See “INSTALL DISCHARGE CHUTE / CHUTE ROTATER HEAD” in the As sem bly / Pre-Operation section of this manual. 1. REMOVE GASOLINE FROM FUEL TANK - Drain gasoline from fuel tank into a suitable container, outdoors, away from fire or flame. Wipe up any spilled gasoline. 2. REMOVE DISCHARGE CHUTE - Loosen locknut se cur ing chute rotator head to mounting bracket only enough to allow chute rotator head to be raised and dis charge chute to be removed from snow thrower. 3. REMOVE BELT COVER - See “TO REMOVE BELT COVER” in this section of this manual. 4. REMOVE ENGINE PULLEY - Remove bolt and flat washer securing pulley to engine crankshaft. Remove outside (auger) pulley only from crank shaft. 5. SEPARATE SNOW THROWER - With your assistant standing in the operating position holding the handles, re move the two (2) bolts holding auger housing and frame together. WARNING: As the last bolt is removed, have your assistant carefully lower the han dles down to the ground. 6. REMOVE AUGER BELT from around pulley. 7. RELIEVE TENSION ON TRACTION DRIVE BELT IDLER and remove traction drive belt from around pulleys.

Tire sealant also prevents tire dry rot and cor ro sion. TO REMOVE WHEELS (See Fig. 25) • Remove the klik pin and remove wheel from axle. IMPORTANT: When installing wheel, be sure to use the axle hole closest to the end of the shaft – do not use the hole in the wheel hub (if equipped). Inner hole in axle and hole in wheel hub are not used for your model snow thrower. AXLE KLIK PIN (INSTALL IN OUTER HOLE OF AXLE ONLY) OUTER HOLE WHEEL WHEEL HUB FIG. 25 ENGINE See engine manual. CARBURETOR Your carburetor is not adjustable. Engine performance should not be affected at altitudes up to 7,000 feet (2,134 meters). If your engine does not operate properly due to suspected carburetor problems, take your snow thrower to a qualified service center. ENGINE SPEED Never tamper with the engine governor, which is factory set for proper engine speed. Overspeeding the engine above the factory high speed setting can be dangerous and will void the warranty. If you think the engine-governed high speed needs adjusting, contact a qualified service center, which has proper equipment and experience to make any necessary ad just ments. TO ADJUST CABLE TENSION (See Fig. 26) Adjust cable tension by turning the adjuster turn buckle, located on the right hand cable. Grasp the long section tightly and turn the short section to lengthen the adjuster. Adjust until cable is snug.
