SAFETY INSTRUCTIONS
Abrasive discs for different materials
Diamond blades
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.
Rescue blade for K960
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
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.
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.
Disc type
Material
Concrete disc
Concrete, asphalt, stone masonry, 
cast iron, aluminium, copper, 
brass, cables, rubber, plastic, etc.
Metal disc
Steel, steel alloys and other hard 
metals.
!
WARNING! Avoid using abrasive discs with 
water. The strength is impaired when 
abrasive discs 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! 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.
!
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.
