Diamond blades
General
• Diamond blades consist of a steel core provided with
segments that contain industrial diamonds.
Diamond blades for different materials
• 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.
Sharpening diamond blades
• Always use a sharp diamond blade.
• 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 blade by cutting in a soft material such as
sandstone or brick.
Diamond blades and cooling
Water cooling must always be used. When wet cutting,
the blade is continuously cooled to prevent overheating.
Water cools the blade and increases its service life while
also reducing the formation of dust.
Vibrations on diamond blades
The blade can become out of round and vibrate if a too
high feed pressure is used.
A lower feed pressure can stop the vibration. Otherwise
replace the blade.
Drive
On account of the machine’s unique design the driving
power is not transferred at the centre of the blade. The
flanges on the two guide rollers run in the blade’s groove.
Springs on the guide rollers press out the rollers, which in
turn press the V-shaped edge on the inside diameter of
the blade against the V-shaped groove in the drive wheel.
The drive wheel is fitted on an axle which is driven by the
engine via a drive belt.
This allows a total cutting depth of 270 mm (10,6 inches)
with a 350 mm (14 inches) diamond blade.

WARNING! Blades can break and cause
serious injuries to the user.
The blade manufacturer issues warnings
and recommendations for the use and
proper care of the blade. Those warnings
come with the blade.
A 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 blade.
!
WARNING! Never use a blade with a
lower speed rating than that of the
machine. Only use ring cutter blades
designed by Husqvarna for use on this
machine.
!
WARNING! Never use a blade for any
other materials than that it was intended
for.
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.
Diamond blades become very hot when
used. An overheated blade is a result of
improper use, and may cause
deformation of the blade, resulting in
damage and injuries.
Cutting metal generates sparks that may
cause fire. Do not use the machine near
ignitable substances or gases.
!
WARNING! Ring blades used on this saw
must be used continuously with water to
prevent overheating that can cause the
ring blade to break resulting in injury and
damage.
NOTICE! The roller setting should be checked twice
during the life of the diamond blade, once after fitting the
blade and when the blade is semi worn.
