MAINTENANCE

Reconstructing 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.
