Safety Information
Warning: Read and understand all safety warnings and instructions before use. Failure to follow these instructions can result in electric shock, fire, or serious injury. Always wear eye protection and use the provided auxiliary handle for maximum control. Ensure the work area is clean, well-lit, and free of flammable materials. Never operate the tool without the appropriate guard.
Operation
Before starting, ensure the tool is in the correct working position. The on/off switch includes a built-in switch-on interlock to prevent unintentional starting. For grinding, maintain a 5° to 30° angle of attack with moderate pressure. When cutting, maintain a moderate feed rate and keep the tool at approximately 90° to the cutting plane. Always wait for the tool to come to a complete stop before laying it down.

Maintenance and Care
Regularly clean the air vents and the dust filter to prevent electrical malfunctions. Use only genuine Hilti spare parts and consumables. If the tool or its power cord shows signs of damage, stop use immediately and contact Hilti Service. Always unplug the tool before performing any maintenance or changing accessories.

- Product does not start: Check the power supply or have the cord/plug inspected by a qualified specialist.
