SAFETY INSTRUCTIONS
• Be alert to movement of the work piece or anything else
that can occur, which could cause the cut to close and
pinch the blade.
Pull in
Pull in occurs when the disc’s lower section suddenly stops or
when the cut closes. (To avoid, see the heading ”Basic rules”
and ”Jamming/rotation”, here below.)
Pinching/rotation
If the cut is pressed together this can lead to jamming. The
machine can be pulled down suddenly with a very powerful
jerk.
How to avoid pinching
Support the work piece in such a way that the cut remains
open during the cutting operation and when the cut is
finished.
Diamond blades
Diamond blades consist of a steel body provided with
segments that contain industrial diamonds.
Always use a sharp diamond blade. Sharpen the blade by
cutting in a soft material such as sandstone or brick.
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.
Diamond blades are ideal for masonry, reinforced concrete
and other composite materials. Diamond blades are not
recommended for cutting metal.
Water cooling
Diamond blades should be sprinkled with water while cutting
to cool the blade and to bind dust that forms while cutting.
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.
Vibrations on diamond blades
The blade can become out of round and vibrate if a too high
feed pressure is used.
A lower feed pressure can stop the vibration. Otherwise
replace the blade. The blade shall be intended for the material
to be cut.
!
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! Cool diamond blades
continuously with water to prevent
overheating that can cause the diamond
blade to break and pieces being thrown off
resulting in injury and damage.
