3.2
Intended use
The product described is a hand-held electric angle grinder. It is designed for cutting, grinding and sanding
metal and mineral materials without use of water.
The tool may be operated only when connected to a power supply providing a voltage and frequency in
compliance with the information given on its rating plate.
•
The power tool may be used for cutting, slitting and grinding mineral materials only when equipped with
the corresponding guard (optional accessory).
•
A dust removal hood together with a suitable Hilti vacuum cleaner must be used for working on mineral
materials such as concrete or stone.
3.3
Items supplied
Angle grinder, side handle, standard guard, front cover, clamping flange, clamping nut, wrench, operating
instructions.
Other system products approved for use with this product can be found at your local Hilti Store or at:

3.4
Integrated brake
This product has an integrated brake. It reduces the time that the accessory tool needs to run down to a
complete stop.
Temperature increase of braked angle grinders!
The integrated brake causes the temperature of the gear head to rise as power and speed increase.
This is not a fault.
It is permissible for the gear housing to reach a temperature 60 °C above ambient temperature. All our
products are below this limit in operation.
3.5
Starting current limiter
The electronic starting current limiter reduces the starting current drawn to prevent the line fuse from tripping.
This prevents abrupt start-up of the product.
3.6
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.
3.7
Active Torque Control (ATC)
The electronics detect potential stalling of the disc and prevent further rotation of the arbor by switching off
the product.
If the ATC system has been triggered, restart the product. Do this by releasing the on/off switch and then
pressing it again.
If the ATC system fails, the product will run at greatly reduced speed and with greatly reduced torque.
Have the product checked by Hilti Service.
3.8
Restart interlock
The product does not restart by itself when the on/off switch is locked in the ON position and power is restored
after an interruption in the electric supply. The on/off switch must first be released and then pressed again.
3.9
Temperature-dependent motor protection
The temperature-dependent motor protection system monitors current draw and motor temperature to
prevent the product from overheating.
If the motor is overloaded through application of excessive working pressure, the product's performance
drops noticeably or it might stall completely. A standstill should be avoided. The product's permissible
overload depends on motor temperature and is not a specific value.
