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 incorrectlybyuntrainedpersonnelorwhenusednot
as directed.
Modification of the power tool or tampering with its parts is not permissible.
2.2 Switches
On / off switch with switch-on interlock
2.3 Items supplied as standard include:
1 Power tool
1Guard
1Sidehandle
1 Clamping flange
1Clampingnut
1Wrench
1 Operating instructions
1 Cardboard box
2.4 Starting current limitation
The electronic starting current limiter reduces the starting current drawn by the power tool and thus prevents the
mainsfuseblowing.Italsoallowsthepowertooltostartsmoothly,without a jolt.
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.
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.
2.6 Restart interlock
The power tool does not restart by itself when the switch remains pressed or is locked 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 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.
Recommended minimum conductor cross section and max. cord lengths
Conductor cross section 14 AWG 12 AWG
Mains voltage 110-120 V 75 ft 125 ft
Do not use extension cords with 16 AWG conductor cross section.
2.8 Using extension cords outdoors
When working outdoors, use only extension cords that are approved and correspondingly marked for this application.
2.9 Using a generator or transformer
This power tool may be powered by a generator or transformer when the following conditions are fulfilled: The unit
must provide a power output in watts of at least twice the value printed on the type identification plate on the power
tool. The operating voltage must remain within +5% and -15% of the rated voltage at all times, frequency must be in
