Care of the product

  • DANGER
    Electric shock due to breakdown of protective insulation. When working on metal under extreme conditions, conductive dust may accumulate inside the power tool, thereby adversely affecting the protective insulation.
  • Use a stationary dust extraction system when working under extreme conditions.
  • Clean the air vents frequently.
  • Use a ground fault circuit interrupter (PRCD) in the electric power supply line to the power tool.
    WARNING
    Electrical hazards. Improper repairs to electrical parts may lead to serious injuries.
  • Electrical parts may be repaired only by trained electrical specialists.
  • Never operate the product when the air vents are blocked. Clean the air vents carefully using a dry brush. Do not allow foreign objects to enter the interior of the product.
  • Keep the product, especially its grip surfaces, clean and free from oil and grease. Do not use cleaning agents containing silicone.
  • Clean the outside of the product at regular intervals using a slightly dampened cloth. Do not use a spray, steam pressure cleaning equipment or running water for cleaning.

    Frequent work on conductive materials (e.g. metal, carbon fiber) may make shorter maintenance intervals necessary. Take your individual workplace risk assessment into account.

Intended use

The product described is a hand-held electric angle grinder. It is designed for cutting and grinding metal and mineral materials, and for brushing, sanding and drilling in tiles, all without use of water. It may used only for dry cutting / grinding.

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 and front cover.

  • A dust removal hood together with a suitable Hilti vacuum cleaner must be used for working on mineral materials such as concrete or stone.

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.

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.

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.

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.

Temperature-dependent product 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 product’s performance drops noticeably or it might stall 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.

Front cover for the disc guard

When grinding with straight grinding discs and cutting with cutting discs in metalworking applications, use the standard guard with front cover.

DG-EX 125/5″ dust hood for grinding (accessory)

The grinding system is suitable only for occasional use with diamond cup wheels for grinding mineral materials.
CAUTION Use of this hood for working on metal is prohibited.

DC-EX 125/5″M dust hood for grinding (accessory)

The power tool may be used for cutting and slitting work on mineral materials only when fitted with a dust hood.
CAUTION Use of this hood for working on metal is prohibited.
