Some Husqvarna blades are available with side
clearance wear indicators to help determine a blade's
lifespan.

Toothed blades

WARNING: Never use toothed blades such
as wood cutting blades, circular toothed
blades, carbide tipped blades, etc. The risk
of kickback is significantly increased and tips
can be torn off and thrown at high speed.
Carelessness can result in serious personal
injury or even death.
WARNING: Government regulation requires
a different type of guarding for carbide
tipped blades not available on power cutters
– a 360 degree guard. Power Cutters (this
saw) use abrasive or diamond blades and
have a different guarding system which does
not provide protection against the dangers
presented by wood cutting blades.
Use of this power cutter with a carbide tipped blade is a
violation of work safety regulations.
Due to the hazardous nature and exigent circumstances
involved with fire fighting and rescue operations
conducted by the various highly trained public safety
forces, safety professionals (fire departments),
Husqvarna is aware that they may use this power cutter
12
with carbide tipped blades in certain emergency
situations due to the ability of carbide tipped blades to
cut many different types of obstructions and materials in
combination without having to take time to switch blades
or machines. When using this power cutter be aware at
all times that carbide tipped blades are more kickback
prone than abrasive or diamond blades if not used
properly. Carbide tipped blades can also throw pieces of
material away from the blade.
For these reasons, a power cutter equipped with a
carbide tipped blade should never be used except by
highly trained public safety professionals who are aware
of the risks associated with its use and then only in
those exigent circumstances when other tools are
deemed inefficient and ineffective for fire or rescue
operations. A power cutter equipped with a carbide
tipped blade should never be used to cut wood in non-
rescue operations.
To examine the spindle shaft and
flange washers
Examine the flange washers and the spindle shaft when
the blade is replaced.
CAUTION: Use only flange washers
supplied by Husqvarna with minimum
diameter 105mm/4.1in.
CAUTION: Do not use warped, notched,
indented or dirty flange washers.
CAUTION: Do not use different dimensions
of flange washers.
1. Make sure that the threads on the spindle shaft are
undamaged.
2. Make sure that the contact surfaces on the blade
and the flange washers are undamaged, of the
correct dimension, clean, and that they run properly
on the spindle shaft.
