Operating instructions for Hilti DCG 230-D / DAG 230-D angle grinder

Quick guide from the manual

The Hilti DCG 230-D and DAG 230-D are professional angle grinders designed for cutting and grinding metal and mineral materials. Important: Always read the full safety instructions before use. Ensure the side handle is fitted for all types of work. The tool must be connected to a power supply matching the voltage on the identification plate. Always wear appropriate personal protective equipment (eye protection, hard hat, ear protection, gloves, breathing protection).

Product description

The power tool features an on/off switch (hold to run), a vibration-absorbing grip, and a pivotable hoop grip. It includes advanced safety features such as ATC (Active Torque Control), which detects disc sticking and switches the tool off, and a restart interlock, which prevents the tool from starting automatically after a power interruption.

Assembly and installation

• Side handle: Must be fitted for all types of work; can be screwed onto the right or left side.
• Guard: The closed side of the guard must always face the operator. To fit, release the clamping lever, engage the keyed locating lug in the recess, rotate to the desired position, and secure by closing the lever.
• Disc installation: Ensure the disc speed rating is at least 6500/min. Clean the clamping flange and fit it onto the drive spindle. Fit the insert tool, then screw on the clamping nut. Use the wrench to tighten while holding the spindle lockbutton.
• Kwik-Lock nut: An optional quick-release nut that requires no tools for changing discs. Ensure the arrow on the nut is within the index marks.

Operation

To switch on, slide the on/off switch forward and press it as far as it will go. To switch off, release the switch. When cutting, apply moderate feed pressure and do not tilt the disc. For rough grinding, maintain an angle of 5° to 30° with the working surface.

Care and maintenance

Regularly clean the air vents with a dry brush to prevent dust accumulation, which can cause electrical hazards. Do not use spray or running water for cleaning. If the tool starts with a jolt, the electronic control unit may be defective; have it repaired by Hilti Service. Check the supply cord regularly for damage.

Troubleshooting

If the tool does not start, check the power supply, the supply cord/plug, or if the carbon brushes are worn. If the tool does not achieve full power, check if the extension cord conductor cross-section is adequate or if there is a malfunction in the ATC system.
