Safety warnings for diamond cutting discs

• Regularly clean the clamping set, spindle and cutting disc.

• Pay attention to the dimensions of the cutting disc. The bore in the cutting disc must match the hub flange and must not be enlarged under any circumstances.

• Ensure that the permitted maximum speed of the cutting disc matches at least the maximum speed of the power tool.

• Check the cutting disc before using it. The cutting disc must be fitted properly and be able to rotate freely. Carry out a test run for at least 30 seconds with no load. Do not under any circumstances use damaged, out‑of-round or vibrating cutting discs.

• Do not press or tilt the cutting disc during cutting. Work with moderate feed adapted to the material being cut. Avoid hard initial contact or stabbing.

• Do not overload the cutting discs because overloaded cutting discs quickly become blunt. Take breaks when dry cutting to allow the disc to cool.

• Work only at right angles and positioned in a straight line.
  Curved cuts and tilting can lead to cracks in the core or segment breaks.

• The cutting discs sharpen themselves. A noticeably decreasing work rate and sparking all around the rim of the disc are indications of a cutting disc that has become blunt. In this case, sharpen the cutting disc by making short cuts in abrasive material (e.g. sandstone). Sporadic sparking is normal when working on stone and is therefore not a problem.

• Do not touch cutting discs until they have cooled down. The cutting discs become very hot whilst working.

• Remove the cutting disc before transporting the power tool in order to prevent damage.

• Use a protective guard, cutting guide and dust extraction device when working with angle grinders. Avoid making deep cuts. Always feed the power tool against the direction of rotation of the disc. Otherwise it may be pressed out of the cut in an uncontrolled manner.

• If wet cutting is allowed, make sure that the water supply is uninterrupted.

• Using inserted Bosch rings is permitted if they are mounted correctly in accordance with figure B (see page 5).
