SNOW THROWER

TO ADJUST SNOW THROWER HEIGHT

See “TO ADJUST SKID PLATES” and “SCRAPER BAR” in the Operation section of this manual.

CHUTE DEFLECTOR

The chute deflector, attached to the top of the discharge chute, is provided to direct discharging snow away from the operator. If the deflector becomes damaged, it should be replaced.

WARNING: To avoid serious injury, never operate your snow thrower with the deflector removed or damaged.

To change direction and/or distance snow is discharged, see “TO CONTROL SNOW DISCHARGE” in the Op- eration section of this manual.

SHEAR BOLTS (See Fig. 21)

AUGER SHEAR BOLTS

Both right and left-hand augers are secured to the auger shaft with a shoulder/shear bolt and hex nut. Should a for- eign object or ice become lodged in the augers, the shear bolts are designed to break, preventing damage to any other components. If one or both augers do not turn when auger control lever is engaged, check to see if one or both of the bolts have sheared. To replace the shear bolts:

1.Disengage all controls and move throttle control to STOP position. Wait for all moving parts to stop.

2.Remove safety ignition key and disconnect spark plug wire from spark plug. Place wire where it cannot come in contact with plug.

3.Align hole in auger hub with hole in auger shaft and install a new 1/4-20 x 2" shoulder/shear bolt with spacer. Install 1/4-20 lock nut and tighten securely.

CAUTION: Do not substitute. Use only original equipment shear bolts as supplied with your snow thrower.

4.Connect spark plug wire to spark plug. Replace safety ignition key

IMPELLER SHEAR BOLTS

The impeller is secured to the impeller shaft with two (2) capscrew/shear bolts and hex nuts. Should a foreign object or ice become lodged in the impeller, the capscrews are designed to break, preventing damage to any other com- ponents. If impeller does not turn when auger control lever is engaged, check to see if the capscrews have sheared.

1.Disengage all controls and move throttle control to STOP position. Wait for all moving parts to stop.

2.Remove safety ignition key and disconnect spark plug wire from spark plug. Place wire where it cannot come in contact with plug.

3.Align holes in impeller hub with holes in impeller shaft and install two (2) new 1/4-20 x 1-5/8" capscrew/shear bolts. Install 1/4-20 locknuts and tighten securely.

CAUTION: Do not substitute. Use only original equipment capscrew/shear bolts as supplied with your snow thrower.
