5. Safety precautions

5.1 Basic information concerning safety
In addition to the information relevant to safety given in each of the sections of these
operating instructions, the following points must be strictly observed at all times.
5.2 Correct use
The tool is designed for cutting, grinding and brushing metals and stone materials
without use of water. Use of a carriage is mandatory when cutting stone.
The working environment may be on a construction site or in a workshop and may
consist of renovation, conversion or new building work.
The tool may be operated only when connected to a power supply providing a volt-
age and frequency in compliance with the information given on its rating plate.
● Use only synthetic resin-bonded, fiber-reinforced grinding or cutting discs and dia-
mond cup wheels approved for use at a peripheral speed of 80 m/sec.
● The tool may be used for dry cutting or grinding only.
● Materials containing asbestos may not be cut or ground with this tool.
● When grinding stone, a vacuum cleaner equipped with a stone dust filter, e.g. the
Hilti TDA-VC40/60 vacuum cleaner, must be used.
● Manipulation or modification of the tool is not permissible.
● To avoid the risk of injury, use only original Hilti accessories and ancillary equip-
ment.
● Observe the information printed in the operating instructions concerning opera-
tion, care and maintenance.
● The tool and its ancillary equipment may present hazards when used incorrectly
by untrained personnel or not as directed.
5.3 Take the necessary precautions to make the workplace safe
● Ensure that the working area is well lit.
● Ensure that the working area is well ventilated.
● Objects which could cause injury should be removed from the working area.
● When working, keep other persons, particularly children, outside the range of the
tool.
● Avoid unfavorable body positions.
● Sparks may fly when cutting or grinding. Take care to ensure that flying sparks pre-
sent no hazard to persons. Due to the risk of fire, no inflammable materials should
be in the vicinity (within the range of flying sparks).
● Take note of the direction of rotation of the disc. Always hold the tool in such a way
that sparks and dust are directed away from the body.
● Wear non-slip shoes and always ensure that you have a secure stance.
● It is recommended that rubber gloves are worn when working outdoors.
