The augers are secured to the auger shaft with special bolts (see figure below) that are designed to break (to protect the machine) if an object becomes lodged in the auger housing. Use of a harder bolt will destroy the protection provided by the shear bolt.

IMPORTANT: To ensure safety and perfor- manse levels, only original equipment shear bolts should be used. When replacing shear bolts, be sure to replace shear bolt spacers.

To replace a broken shear bolt, proceed as follows:

•Move the throttle to O (STOP) and turn off all controls.

•Disconne_ the spark plug wire. Be sure all moving parts have stopped.

•Align the hole in the auger tube with the hole in the auger shaft. Install the new shear pin and shear bolt spacer found in toolbox on top of belt cover.

NOTE: Spacer fits inside the larger hole in the auger tube.

•Reconnect the spark plug wire.
