Reconstructing (re-tipping) the blade
NOTICE! The support rollers do not drive the blade.
When worn rollers are replaced with new ones, you must
adjust the rollers against the blade.
Incorrect adjustment can result in damage to the blade.
See the instructions under the Assembly and Settings
heading.
If the blade rotates slowly or stops, stop cutting
immediately and trouble shoot.
!
WARNING! Do not put new diamond
segments on a used blade core (re-
tipping). The blade core is designed to
handle the stress it is exposed to during
the use of the original segment. If the
blade is re-tipped the additional stress
on the blade core might it to break or
crack and cause serious injury to the
operator. For this reason Husqvarna
does not approve ring cutting blades that
have been re-tipped. Contact your
Husqvarna dealer for instructions.
