Shear Bolts
1. Always use a grade 2 shear bolt (669596) on
the fan (item 1) and special grade 5 grooved
shear bolts (657295) on the auger sections
(item 2).
2. Check the tightness of the shear bolts at
regular intervals to make sure the snowblower
is safe.
Repositioning of the Augers
After a shear bolt breaks on one of the
augers, be sure to reposition the screws as
shown in the figure below, so that they are
180° away from each other.
Visual inspection of the driveline , hydraulic/electrical
connectors and hitch connection points. Clean if
necessary.
