water. The strength is impaired when
abrasive blades are exposed to water or
moisture, which results in an increased risk
of the blade breaking.

Diamond blades

General
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.
• 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.
Diamond blades for different materials
• Diamond blades are ideal for masonry, reinforced
concrete and other composite materials.

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.
Diamond blades for dry cutting can be used both with and
without water cooling.
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. If this is not done, the blade may be overheated.
Diamond blades for wet cutting must be water cooled. If
this is not done, the blade may be overheated.
Water cooling cools the blade and increases its service
life while also reducing the formation of dust.
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.
Store cutting blades in dry, frost free conditions. 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.
