Diamond blades for wet cutting
WARNING:
dimension that is specified for the current
blade dimension. Do not use blade flanges
that are damaged.
During the operation, the friction causes the diamond
blade to become very hot. If the diamond blade
becomes too hot, it will decrease the blade tension or
make the core crack.
Let the diamond blade become cool before you touch it.
• Diamond blades for wet cutting must be used with
water to keep the diamond blade core and segments
cool during cutting. Diamond blades for wet cutting
can not be used dry.
• If you use diamond blades for wet cutting without
water, the diamond blade can become too hot. This
gives bad performance, blade damage and is a
safety risk.
Diamond blades for dry cutting
• For diamond blades for dry cutting it is necessary
to have a sufficient airflow around the cutting
blade to decrease the temperature. Because of this,
diamond blades for dry cutting are recommended
only for intermittent operation. After some seconds
of operation, it is necessary to let the diamond blade
rotate freely, away from the cut. This lets the airflow
around the blade decrease the temperature of the
diamond blade.
Toothed blades
WARNING:
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:
requires a different type of guarding for
carbide tipped blades not available on power
cutters – a 360 degree guard. Power Cutters
(this saw) use diamond blades and have
a different guarding system which does
not provide protection against the dangers
presented by wood cutting blades.

Always use a blade flange
Never use toothed blades
Government regulation
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 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 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 the
flange washers
WARNING:
washers with a minimum diameter of 67
mm/2.6 in.
WARNING:
or dirty flange washers. Use only flange
washers of the same dimension. Incorrect
flange washers can cause the cutting blade
to become damaged or come loose.
Examine the spindle shaft and the flange washers when
you replace the cutting blade.
Use only Husqvarna flange
Do not use damaged, worn
