Diamond blades

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 consist of a steel body 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.
Always use a sharp diamond blade.
Material
Diamond blades are ideal for masonry, reinforced concrete
and other composite materials. Diamond blades are not
recommended for cutting metal.
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.
SAFETY INSTRUCTIONS
Rescue blade for K960
WARNING! The Rescue blade is to be used
!
only for rescue missions and only by trained
staff. Carelessness can result in serious
personal injury or even death.
The Rescue-blade is intended for the cutting of most
materials, even in combination, which are found in connection
with rescue services. e.g. thin sheet steel (not stainless steel
or hardened steel), aluminium, wood, plaster and other
diverse, mixed materials. The Rescue-blade is not intended
for stone materials.
Dry cutting with diamond 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.
Wet cutting with diamond blade
Water cooling, which is used when cutting concrete, cools the
blade and increases its service life while also reducing the
formation of dust.
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.
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.
