REPLACING AUGER BELT

•Raise the snow thrower to the transport position.

•Release the spring tension on the drive belt idler.

•Release the spring tension on the auger belt idler.

•Remove the belt cover and loosen the belt keeper bracket (items 18 and 19 on page 18).

•Remove the auger belt from the clutch/idler assem- bly and from the spiral auger housing.

•Install new belt around top of auger drive pulley

and underneath the two side idler pulleys. Twist the belt 1/4 turn to seat it in each idler pulley.

•Reinstall the belt cover and tighten the belt keeper bracket (items 18 and 19 on page 18).

•Assemble the belt onto the clutch/idler assembly as instructed for figure 18 on page 11.

LIFT RELEASE CABLE ADJUSTMENT

•If the lift rod does not lock the snow thrower securely in the transport position, loosen the upper hex nut on the lift bracket a few turns and tighten the lower hex nut. See figure 10 on page 8.

•If the lift rod fails to unlock completely to lower the snow thrower to the ground, loosen the lower hex nut on the lift bracket a few turns and tighten the upper hex nut. Refer to figure 10 on page 8.

SPIRAL AUGERS

•The spiral augers are secured to the auger shaft with two shear bolts and hex lock nuts. If you hit a foreign object or if ice jams the augers, the snow thrower is designed so that the bolts will shear.

•If the augers will not turn, check to see if the shear bolts have sheared. See figure 22. Two replace- ment shear bolts and hex lock nuts have been provided with the snow thrower. For future use order part number 710-0891 shear bolt and number 43064 hex lock nut.

SKID SHOE, LEVELING SHOE ADJUSTMENT

(The snow thrower must be attached to the tractor for correct adjustment of the shoes.)

•The skid shoes regulate the distance the scraper plate is raised above the plowing surface. They are mounted on each side of the spiral auger housing. The leveling shoes help maintain the snow thrower in a level position. They are mounted just behind the auger housing.

•When removing snow from a gravel driveway or an uneven surface, it is advisable to keep the scraper plate as high above the surface as possible to prevent possible damage to the spiral auger. On a smooth blacktop or concrete surface, keep the scraper plate as close to the surface as possible.

•To adjust the skid shoes, raise the snow thrower off the ground and place a wood block under each end of the scraper plate. Loosen the six hex nuts securing the skid shoes to the housing. Adjust the skid shoes up or down to the desired position and tighten the nuts securely. Both skid shoes should be the same height to keep the housing and the scraper plate level. See figure 23.

•The skid shoes may be turned to face either in or out. In order to obtain the lowest setting, where the scraper blade fully contacts the ground, the skid shoes must be facing out as shown in figure 23.

•Before adjusting the leveling shoes, make sure the skid shoes are properly adjusted. With the snow thrower in the lowered position, loosen the bolts which fasten the leveling shoes to the thrower and adjust the leveling shoes to solidly contact the ground. Retighten the bolts. See figure 23.
