BLADES
General
• Diamond blades consist of a steel core provided with
segments that contain industrial diamonds.
Water cooling
• Water cooling must always be used. When wet cutting, the
blade is continuously cooled to prevent overheating.
Diamond blades for different
materials
• 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 blunt 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 260 mm (10 inches) with a
350 mm (14 inches) diamond blade.

4 Guide rollers
5 V-shaped edge
Checking wear
As the blade is used the inside diameter and the groove in the
drive wheel become worn.
The ring cutter will also work well in the future if:
• the drive wheel is not too worn
1) New
2) Worn
• the guide rollers are not too worn
1) New, 3 mm (0.12’’)
2) Worn, ≤ 1,5 mm (0.06’’)
!
WARNING! Cutting plastics with a diamond
blade can cause kickback when the material
melts due to the heat produced when cutting
and sticks to the blade.
!
WARNING! Diamond blades get 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.
!
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.
