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. 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.
Cutting in metal generates sparks that
may cause fire. Do not use the machine
near to ignitable substances or gases.
Cutting metal is not allowed with the Vac
attachment.
• Diamond blades consist of a steel core provided with
segments that contain industrial diamonds.

CUTTING BLADES
• 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.
• Diamond blades are available in several hardness
classes.
• Special blades should be used when cutting metal.
Ask your dealer for help in choosing the right product.
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.
Diamond blades for dry cutting
• 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
NOTICE! Wet cutting should not be performed with the
Vac attachment. Wet concrete sludge considerably
reduces the suction capacity of the Vac attachment.
• 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.
