Tighten screws in control bracket. 5. Check adjustment by moving lever to each position. Be sure to check to see that NEUTRAL is properly reached from both forward and reverse directions. 6. Check shift lever movement from reverse to 3rd and make sure lever does not contact handles. To adjust, loosen two screws indicated in figure 9, move lever slightly, then tighten the screws and check again. DRIVE BELTS The snowthrower is equipped with two drive belts located just in front of the engine under the belt cover (figure 10). Figure 11 shows both belts and idler pulleys. The belt nearest the engine is the unit drive (wheels) belt. The belt farthest from the engine is the auger/impeller drive belt. Do not go near the discharge chute or auger when the engine is running. Do not run the engine with Shift control b for step 6 Figure 9. Shift Control Adjustment 11 Adjusting Drive Belts If the auger or wheels slip under load, belts could be stretched or worn. Adjust as follows: 1. Remove the belt cover (figure 10). Determine which belt requires adjustment. 2. Loosen the locknut on the appropriate idler pulley and move the idler pulley i/4” toward the belt (figure 11). Tighten the locknut. 3. Re-install the belt cover. 4. Determine if additional adjustment is required by trying the unit. Repeat step 1 - 3 if necessary. NOTE: If auger or wheels continue to slip after adjusting the idler pulleys, the spring (figure 12) on either control rod might be stretched and worn and require replacement. Replace either the auger control rod spring or drive control rod spring as necessary, then repeat steps I-4. Adjusting Belt Guides Check each belt guide for proper clearance using the following procedure. NOTE: Belt guides on 7 HP mode/s are slight//y different than shown, but adjustment is the same. I. Remove the belt cover (figure IO). 2. Have someone hold both the auger and drive clutch levers tight against the handgrips (figure 12). 3. Loosen the screw securing the belt guide (figure 11). Adjust the guide so it clears the belt by l/16” l/8”. The clearance should be equal on both side of the pulley. Tighten the screw securely. NOTE: When adjusting the right belt guide, make sure guide does not contact the pulley hub. 4. Re-install the belt cover. Replacing Drive Belts The drive belts on this snowthrower are of special construction and should be replaced with original equipment belts available from your dealer. See COMMON REPLACEMENT PARTS at the back of tfiis.manual for part numbers. Use the following procedure to replace either drive belt. 1. Remove gas from fuel tank and run engine until it stops running from lack of fuel. 2. Disconnect spark plug wire and fasten it away from the spark plug. 3. Remove belt cover (figure 10).

Pivot the belt guide as necessary and remove the drive belt from the pulley. 5. Stand the snowthrower up onto the auger end. 12 A CAUTION Place a block (approximately 4” high) under front edge of auger housing or snowthrower will not stand on end. 6. See figure 13. Loosen nuts holding lower belt guard and slide guard away from belt. 7. Remove belt from between large pulleys. 13. Slide new belt onto pulley and position lower belt guard to within l/16” - i/8” of large drive pulley. Tighten nuts securing lower belt guard. 9. Return snowthrower to upright operating position. 10. Place new belt onto engine pulley. 11. Adjust guides as described under ADJUSTING BELT GUIDES. 12. Install belt cover. Figure 13. Lower Belt Guard 13. Connect spark plug wire and fill fuel tank.

Rotate the wheel (figure 13) to locate the roller chain master link (figure 14). 5. Remove the keeper link, master link and chain. 6. Install new chain and keeper link as shown in figure 14. 7. Return snowthrower to upright operating position. 8. Connect spark plug wire and fill fuel tank. SHEAR PIN REPLACEMENT, If the auger strikes an object which could cause damage to the unit, the shear pin will break. This protects the gear box and other parts from damage. The shear pins are shown in figure 15. To replace, install a new shear pin and cotter pin. Spread the legs of the new cotter pin fully. Do not replace shear pins with bolts, screws or a harder shear pin. Figure 15. Shear Pin Replacement 13 WHEEL AXLE BEARING REPLACEMENT After approximately 100 hours of use (about 5 years), or if drive chain jumps off sprockets, wheel axle bearings may need to be replaced. 1.
