SAFETY INSTRUCTIONS
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.
There is an arrow on the machine that indicates the axleís 
direction of rotation that the disc 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 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.
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 discs. 
Abrasive discs must be stored on a flat, level surface. If an 
abrasive disc is stored in humid conditions, this can cause 
imbalance and result in injury.
Inspect new blades for transport or storage damage.
!
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.

the user.
When wet cutting, the blade is continuously 
cooled to prevent overheating.
