General

WARNING! A cutting blade may burst

and cause injury to the operator. Only
use ring cutter blades designed by
Husqvarna for use on this machine.
The cutting blade manufacturer issues
and provides warnings and
recommendations for proper use and
care of the cutting blades. Read and
follow all instructions.
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.

Water cooling

WARNING! Cool diamond blades for wet
!
cutting continuously with water to
prevent overheating, which may deform
the blade and cause damage to the blade
and injury to the user.
• Water cooling must always be used. When wet
cutting, the blade and the ring drive system is
continuously cooled to prevent overheating.
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, reinforced
concrete and other composite materials.
• We offers a number of blades for different materials in
its range. Check with your Husqvarna dealer to see
which blades are best suited for your usage.

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.

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 370 mm (14 inches) diamond blade.
