HOW TO REPLACE THE AUGER SHEAR BOLT
The augers are secured to the auger shaft
with special shear bolts, These shear bolts
are designed to break and protect the ma-
chine if an object becomes lodged in the au-
ger housing, Do not use a harder bolt as the
protection provided by the shear bolt will be
lost.
,_ WARNING: For safety and to
protect the machine, use only
original equipment shear bolts.
1. Move the throttle control to the stop
position. Disengage all controls.
2. Disconnect the spark plug wire.
Make sure all moving parts have
stopped.
To replace a broken shear bolt, proceed
as follows. Extra shear bolts were pro-
vided in the assembly parts bag.
