Hilti 125-D Bedienungsanleitung Seite 25

Nationally applicable industrial safety regulations must be observed.
Working on materials hazardous to the health (e.g. asbestos) is not permissible.
Modification of the power tool or tampering with its parts is not permissible.
To avoid the risk of injury, use only genuine Hilti accessories and insert tools.
Observe the information printed in the operating instructions concerning operation, care and maintenance.
The power tool is designed for professional use and may be operated, serviced and maintained only by trained,
authorized personnel. This personnel must be informed of any special hazards that may be encountered. The power
tool and its ancillary equipment may present hazards when used incorrectly by untrained personnel or when used not
en
as directed.
Take the influences of the surrounding area into account. Do not use the power tool or appliance where there is a risk
of fire or explosion.
2.2 The items supplied in the cardboard box are:
1 Power tool with guard
1 Front cover (optional)
1 Vibration-absorbing side handle
1 Kwik‑Lock quick-release clamping nut (op-
tional)
1 Flange
1 Nut
1 Wrench
1 Operating instructions
1 Cardboard box
2.3 Starting current limitation
The electronic starting current limiter reduces the starting current drawn by the power tool and thus prevents the
mains fuse blowing. It also allows the power tool to start smoothly, without a jolt.
2.4 Constant-speed electronics
Electronic speed control keeps running speed almost constant irrespective of whether the power tool is idling or
running under load. Constant running speed helps ensure maximum efficiency.
2.5 ATC (Active Torque Control)
The electronics in the power tool detect situations where there is a risk of the disc sticking and prevent further rotation
of the drive spindle by switching the power tool off (does not prevent kickback). The switch must be released and
pressed again to restart the power tool.
2.6 Restart interlock
The power tool does not restart by itself when the switch is locked in the on-position and the power returns after an
interruption in the electric supply. The switch must first be released and then pressed again to restart.
2.7 Temperature-dependent motor protection
The temperature-dependent motor protection system prevents the tool overheating by monitoring current input and
motor temperature.
In the event of motor overload due to application of excessive pressure to the disc, performance will drop noticeably
or the tool may stop running (avoid stalling the tool in this way).
Permissible tool overload cannot be given as a specific value as it depends on the temperature of the motor.
In the event of the tool being overloaded, release the pressure applied and allow the tool to run under no load for
approx. 30 seconds.
2.8 Using extension cords
Use only extension cords of a type approved for the application and with conductors of adequate cross section. The
power tool may otherwise loose performance and the extension cord may overheat. Check the extension cord for
damage at regular intervals. Replace damaged extension cords.
