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.
! | 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. |
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
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.
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.
