Adjust worm gear. See adjustment procedure. 3. Control rod gears misaligned. 3. Adjust gear bracket. See adjustment procedure. Snowthrower veers to one side. 1. Tires pressure not equal. 1. Check tire pressure. 2. One wheel is set in Free-Wheeling mode. (Traction Lock Pin is in the OUTER hole). 2. Make certain the left Traction Lock Pin is in the INNER holes (to engage traction drive). Excessive vibration. 1. Loose parts or damaged auger. 1. STOP engine and REMOVE the key. DISCONNECT the spark plug wire. Tighten all hardware. Replace auger if necessary. If vibration continues, see your dealer. Drive fails to move snowthrower at slow speeds. 1. Traction Drive out of adjustment. 1. Readjust drive, or shift Speed Selector setting up one speed faster. Speed selector difficult to move or frozen in place. 1. Hex shaft needs lubrication. 1. Lubricate hex shaft with 5W-50 synthetic motor oil (see Maintenance). 19 Adjustments SPEED SELECTOR ADJUSTMENT 1. Loosen the two nuts (F, Figure 15). 2. Place the shift lever in 5th gear. 3. Push the lower rod into the housing and tighten the two nuts. Do not lift up or down on rods while tightening. Make sure the shoulders of the carriage bolts (D) are in the slots. 4. Always check traction drive tension and auger drive tension after adjusting speed selector. AUGER DRIVE TENSION 1. With the drive lever released, the hook (B, Figure 15) should barely touch the lever (C) without raising it. There can be a maximum 1/32” clearance as shown. 2. To adjust, loosen the two nuts (G) and hold the lower rod to keep from rotating. Turn the turnbuckle toward the right to lower the spring, or toward the left to raise the spring. 3. Tighten the two nuts against the turnbuckle. Hold the turnbuckle with pliers while tightening the nuts. TRACTION DRIVE TENSION 1. With the drive lever engaged, bottom end of lower rod (D, Figure 16) should be flush with bottom of spring (E). 2. To adjust, loosen the two nuts, (B) and hold the lower rod to keep from rotating. Turn the turnbuckle (C) toward the right to lower rod or toward the left to raise rod. 3. Engage the drive lever to check the adjustment. When correct, tighten the two nuts against the turnbuckle. Hold the turnbuckle with pliers while tightening the nuts. A G D F E F B C Figure 15. Speed Selector and Auger Drive Linkages A. Turnbuckle B. Spring Hook C. Lever D. Carriage Bolts E. Lower Rod F.

Spring 20 Adjustments MANUAL DISCHARGE CHUTE CONTROL LINKAGE ADJUSTMENT Pinion Gear Adjustment If the discharge chute is difficult to operate, first lubricate the pinion gear (A, Figure 17) and ring gear (F). If it is still difficult to operate, adjust as follows: NOTE: If the discharge chute will not stay in position, adjust the pinion gear (A) closer to the ring gear. 1. Loosen the nut (G, Figure 17) which holds the pinion gear bracket in the slotted hole. 2. If the pinion gear is too tight against the ring gear, move it away slightly and then retighten the nut. 3. Check the operation again Gear Bracket Adjustment If the Discharge Chute becomes difficult to rotate or begins to operate erratically, the Chute Direction Control rod gears may require adjustment: 1. Loosen the gear bracket mounting nuts (Figure 18). 2. Slide the gear bracket into the position that provides the best engagement between the gears. 3. Tighten the bracket mounting hardware, and check for smooth operation. 4. Readjust if necessary. 5. Lubricate the Chute Direction Control rod gears with a medium weight (10W) oil ELECTRIC DISCHARGE CHUTE ROTATOR MOTOR ADJUSTMENT If the electric chute rotator does not function properly, check the electrical connections and then perform the procedure below. 1. Remove the rotator motor cover. 2. Lubricate the chute ring gear. 3. Loosen the capscrews (A, Figure 19) securing the rotator motor and adjust so that the motor gear and chute ring gear mesh. Tighten the capscrews. 4. Reinstall the rotator motor cover. B C G A E F D Figure 17. Discharge Control A. Pinion Gear B. Control Rod C. Carriage Bolt D. Slotted Bracket E. U-shaped Bracket F.
