!water. The strength is impaired when abrasive discs are exposed to moisture.

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.

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.
