General

WARNING! A cutting blade may burst and
!
cause injury to the operator.
A cutting blade should be checked before
it is assembled on the saw and frequently
during use. Look for cracks, lost
segments (diamond blades) or pieces
broken off. Do not use a damaged cutting
blade.
Test the integrity of each new cutting
blade by running it at full throttle for about
1 minute.
Only use original cutting blades designed
by Husqvarna for use on this machine.
Husqvarna issues warnings and
recommendations for the use and proper
care of the cutting blades. Those warnings
come with the cutting blades. Read and
follow all instructions from Husqvarna.
• This machine is only to be used with Husqvarna´s
specially developed diamond blades intended for Cut-
n-Break. The blades have an integrated belt pulley
and are approved for freehand cutting.
• Diamond blades consist of a steel core provided with
segments that contain industrial diamonds.
• Always use a sharp diamond blade.
• Ensure the blades are not cracked or damaged in any
other way. Replace blades if necessary.
Diamond blades for different
materials
WARNING! Never use a cutting blade for
!
any other materials than what it was
intended to cut.
Never use a diamond blade to cut plastic
material. The heat produced during cutting
may melt the plastic and it can stick to the
cutting blade and cause a kickback.
Cutting metal generates sparks that may
cause fire. Do not use the machine near
ignitable substances or gases.
• Diamond blades are ideal for masonry and reinforced
concrete. Ask your dealer for help in choosing the
right product.
• Diamond blades are available in several hardness
classes. A "soft" diamond blade has a relatively short
service life and large cutting capacity. It is used for

hard materials such as granite and hard concrete. A
"hard" diamond blade has a longer service life and
reduced cutting capacity, and should be used for soft
materials such as brick and asphalt.

Water cooling

• Water cooling must always be used.
• Using wet cutting blades without water can cause
excessive heat build-up, resulting in poor
performance, severe blade damage and is a safety
hazard.
• Water cools the blade and increases its service life
while also reducing the formation of dust.

Sharpening diamond blades

Diamond blades can become dull when the wrong feeding
pressure is used or when cutting certain materials such
as heavily reinforced concrete. Working with a dull
diamond blade causes overheating, which can result in
the diamond segments coming loose.
Sharpen the blades by cutting a soft material such as
sandstone or brick.

Transport and storage

• Make sure the machine is secured and that the cutting
blades are properly protected during the transport and
storage of the machine.
• Before use inspect all blades for transport or storage
damage.
WARNING! Cool diamond blades
!
designed for wet cutting continuously
with water to prevent heating, which can
deform the diamond blade resulting in
damage to the machine and personal
injury.
