CAUTION:   Always check to see that both ends of the PTO shaft are 
securely attached as per instructions every time you are preparing to use the 
snowblower.

When replacing bearings or tightening a loose bearing collar, always  
tighten collar in the direction of shaft rotation using a center punch or a similar 
tool.  
 
13. 
Shear Sprocket:  The shear sprocket (#43) should be checked at the beginning 
of every season to make sure it will spin freely.  With time the sprocket plate 
could corrode and seize which will not allow the shear bolt to break if something 
jams in the snowblower auger.  Clean to loosen if necessary.
