3.3 Items supplied
Diamond grinder, operating instructions, clamping nut and flange.
To help ensure safe and reliable operation, use only genuine Hilti spare parts and consumables. Spare
parts, consumables and accessories approved by Hilti for use with the product can be found at your local
Hilti Store or online at: www.hilti.group | USA: www.hilti.com
3.4 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.
3.5 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.
3.6 Active Torque Control (ATC)
The electronics detect potential stalling of the disc and prevent further rotation of the arbor by switching off
the tool.
If the ATC system has been triggered, restart the tool. Do this by releasing the on/off switch and then
pressing it again.
If the ATC system malfunctions, the power tool will run only at greatly reduced speed and with greatly
reduced torque. Have the tool checked by Hilti Service.
3.7 Restart interlock
The power tool does not restart by itself when the on/off switch is locked in the on-position and the power
returns after an interruption in the electric supply. The on/off switch must first be released and then pressed
again to restart.
3.8 Temperature-dependent motor protection
The temperature-dependent motor protection system monitors current input and motor temperature and
thus prevents the power tool overheating.
If the motor is overloaded through application of excessive working pressure, the power tool’s performance
drops noticeably or it may stop completely. A standstill should be avoided. No specific value can be given
for the permissible overloading limit for the power tool as it depends on motor temperature.
4 Technical data
For rated voltage, rated current, frequency and/or input power, refer to the country-specific type
identification plate.
If the device is powered by a generator or transformer, the generator or transformer’s power output must be
at least twice the rated input power shown on the rating plate of the device. The operating voltage of the
transformer or generator must always be 5 % and -15 % of the rated voltage of the device.
