● Observe the instructions on care and maintenance and concerning replacement of
the disc in good time.
● Ensure that the disc is compatible with the mounting system used by the tool and
check that the disc is correctly and securely fitted.
● Observe the direction of rotation (indicated by arrow) when fitting the disc.
5.4.2 Electrical
● Check the condition of the tool, supply cord, extension cord and plug connections.
Do not operated the tool if it is found to be damaged, if the tool is not complete or if
its controls cannot be operated faultlessly.
● Do not touch the supply cord in the event of it becoming damaged while working.
Unplug it from the electric socket.
● Damaged or faulty switches must be replaced at a Hilti service center. Do not use
the tool if it cannot be switched on and off correctly.
● The tool should be repaired by a trained electrical specialist (Hilti service center).
● Never carry the tool by the supply cord.
● Grip the plug and not the cord when pulling it out of the socket.
● Do not expose the supply cord to heat, oil or sharp edges.
● When working outdoors, use only extensions cords that are approved and corre-
spondingly marked for this application.
● In the event of a power failure, switch the tool off and unplug the supply cord.
● Avoid using extension cords with multiple sockets and the simultaneous use of
several electric tools connected to one extension cord.
● To avoid the risk of accident, always use only original Hilti spare parts.
● Never operate the tool when it is dirty or wet. Dust or dampness on the surface of
the tool make it more difficult to hold and, under unfavorable conditions, may lead to
electric shocks.
5.4.3 Thermal
Warning:
hot surface
● The disc may become hot during use. Wear protective gloves when changing
discs.
5.4.4 Dust
Respiratory equipment must be worn
● If the tool is operated without a dust extraction system, breathing protection must
be worn by the operator when the work causes dust.
● Ensure that the ventilation openings on the tool remain unobstructed when work-
ing under dusty conditions. Should it become necessary to remove dust that may
have accumulated, first unplug the electric supply cord. Use a non-metallic object
and take care to avoid damage to internal parts of the tool.
● The person responsible for operation of the tool must ensure that hazardous grin-
ding dust is disposed of in accordance with national and regional regulations.
● Conductive dust may accumulate inside the tool when working on conductive mate-
rials, resulting in a short circuit or breakdown of the tool's protective insulation and
thus present a risk of electric shock. Accordingly, the tool must be inspected and its
insulation resistance tested at frequent intervals by a trained specialist at a Hilti repair
center in order to ensure that the tool is free from accumulations of conductive dust
or other conductive deposits.
● An industrial vacuum cleaner equipped with filters of a type suitable for the mate-
rial worked on must be used when grinding.
● Before beginning the work, determine to which class of risk the resulting dust will
belong. Always wear eye protection and ear protection. Other personal protective
