Do not use extension cords with 1.25 mm² or 16 AWG conductor cross sections.
2.11 Using extension cords outdoors
When working outdoors, use only extension cords that are approved and correspondingly marked for this application.
2.12 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 5% and -15% of the rated voltage at all times, frequency must be in
the 50 – 60 Hz range and never above 65 Hz, and the unit must be equipped with automatic voltage regulation and
starting boost.
Never operate other power tools or appliances from the generator or transformer at the same time. Switching other
power tools or appliances on and off may cause undervoltage and / or overvoltage peaks, resulting in damage to the
power tool.
2.13 Grinding / cutting discs with Kwik-Lock quick-release clamping nut (optional)
The Kwik-Lock nut can be used instead of the clamping nut. No tools are then required for changing grinding/cutting
discs.
NOTE
Use of the Kwik-Lock nut with cup wheels, slitting discs, brushes, rubber backing pads, tuck pointing discs (special
discs used for joint repair) or with diamond cup wheels is not permissible.
2.14 DG-EX 125/5" dust removal hood for grinding
2
The power tool is suitable only for occasional use with diamond cup wheels for grinding mineral materials.
CAUTION
Use of this guard for working on metal is not permissible.
NOTE
For cutting, grinding and slitting mineral materials such as concrete or stone it is recommended that the dust removal
hood specially designed for the system is used together with a suitable Hilti vacuum cleaner. These serve to protect
the operator and increase the life of the power tool and disc used.
2.15 DC‑EX 125/5"‑M dust removal hood with guide carriage for cutting and slitting
3
Cutting and slitting work on mineral materials may be carried out only when the power tool is equipped with a dust
removal hood with guide carriage.
CAUTION
Use of this guard for working on metal is not permissible.
NOTE
For cutting, grinding and slitting mineral materials such as concrete or stone it is recommended that the dust removal
hood specially designed for the system is used together with a suitable Hilti vacuum cleaner. These serve to protect
the operator and increase the life of the power tool and disc used.
