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
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 Grips
Vibration-absorbing grip
Pivotable hoop grip
2.3 Switches
On / off switch (hold to run)
2.4 Items supplied as standard include:
1 Power tool
1 Guard
1 Side handle
1 “Kwik-Lock” clamping nut
1 Wrench
1 Operating instructions
2.5 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.
2.6 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.
NOTE
In the event of a fault in the ATC system the power tool will continue to run but at greatly reduced speed and with
lower torque. The power tool must be returned to Hilti Service for servicing.
2.7 Restart interlock
The power tool does not restart by itself when the switch remains pressed and the power returns after an interruption
in the electric supply. The switch must first be released and then pressed again to restart.
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.
