AUGERS AND FAN SHEAR BOLT REPLACEMENT  

Shear bolts are to be considered a preventive measure and not an assured protection. Operator vig-
ilance  is  required. Thoroughly  inspect the  areas where the snowblower is to be used  and  remove 
all foreign  objects.  

To avoid damage to the snowblower:  

Use only the original shear bolts (grooved bolts).  

#4172551-13 bags of 10 for the augers.  
#4172551-14 in bags of 10 for the fan.  

The use of any other shear bolt will not insure any protection and may void the warranty.  

IMPORTANT: 

I

T IS VERY IMPORTANT TO REPLACE THE AUGERS IN THE SAME POSITION AS SHOWN  

IN THE DRAWING BEFORE INSTALLING THE SHEAR BOLTS. ONE SIDE AUGER SHOULD BE OPPO-
SITE OF THE OTHER SIDE.
