MAINTENANCE
Reconstructing (re-tipping) the
blade
!
WARNING! Ring cutter blades must not
be reconstructed. Due to its design, a
ring cutter blade is exposed to other
strains than a centre driven 14 inch
diamond blade. Firstly, the drive wheel is
driven on the inner diameter of the blade
so that both the surfaces of the drive
wheel and the blade are exposed to wear.
The core of the blade becomes thinner
and the guide wider, which prevents the
blade being driven by the wheel.
Secondly, the blade is exposed to loads
from the rollers and from the actual
cutting process when the blade is not
held completely straight. Strain builds up
in the blade until it cracks or breaks if it
has been reconstructed. A shattered
blade can cause serious personal
injuries to the user or other persons. For
this reason Husqvarna does not approve
ring cutting blades that have been
reconstructed. Contact your Husqvarna
dealer for instructions.
