Diamond blades for wet cutting
• Diamond blades for wet cutting must be used with
water.
• Water decreases the temperature of the cutting
blade, increases its service life and decreases dust
during operation.
• When wet cutting, collect the waste water safely.
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.
Diamond blade - side clearance
WARNING:
poor blades can suffer excessive wear on
the side of the segments. Make sure the
diamond segment (A) is wider than the
blade (B). This is to prevent pinching in the
cutting slot and kickback. Refer to
on page 18 .

CAUTION:
worn blades may cause increased wear on
the side of the segments. Replace the blade
before it is worn out.
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.

Certain cutting situations or
Kickback
Some cutting situations and
Never use toothed blades
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.
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
CAUTION:
flange washers with a minimum diameter of
105 mm/4.1 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.
