Abrasive blades for different materials
Diamond blades
Diamond blades consist of a steel core provided with
segments that contain industrial diamonds.
Diamond blades ensure lower costs per cutting operation,
fewer blade changes and a constant cutting depth.
When using diamond blades make sure that it rotates in
the direction indicated by the arrow on the blade.
There is an arrow on the machine that indicates the axleís
direction of rotation that the blade is mounted on.
Always use a sharp diamond blade.
Material
Diamond blades are ideal for masonry, reinforced
concrete and other composite materials.
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
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.
Dry cutting with diamond blade
Wet cutting with diamond blade (K3000 Wet)
Water cooling, which is used when cutting concrete, cools
the blade and increases its service life while also reducing
the formation of dust.
Water connection with flow limiter (K3000 Wet)
There is a flow limiter in the water connector that gives a
constant flow, irrespective of the water pressure. The flow
limiter may not be dismantled.
Transport and storage
• Do not store or transport the power cutter with the
cutting blade fitted. All blades should be removed from
the cutter after use and stored carefully.
• Special care should be taken with abrasive blades.
Abrasive blades must be stored on a flat, level
surface. If an abrasive blades is stored in humid
conditions, this can cause imbalance and result in
injury.
• Inspect new blades for transport or storage damage.
Blade type Material
Concrete blade
Concrete, asphalt, stone
masonry, cast iron, aluminium,
copper, brass, cables, rubber,
plastic, etc.
Metal blade
Steel, steel alloys and other
hard metals.
!
WARNING! Avoid using abrasive blades
with water. The strength is impaired
when abrasive blades are exposed to
moisture.
!
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. A heated blade can be
deformed and cause damage to the
machine as well as the user.
When dry cutting, lift the blade out from
the cut every 30–60 seconds and let it
rotate in the air for 10 seconds to let it
cool.

WARNING! Diamond blades get very hot
when used. A heated blade can be
deformed and cause damage to the
machine as well as the user.
When wet cutting, the blade is
continuously cooled to prevent
overheating.
