Safety Information
Always read and understand all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.
- Work Area Safety: Keep work area clean and well lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust.
- Electrical Safety: Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

- Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
- Safety Switch: The grinder is equipped with a safety switch that cuts off power if excessive pressure is applied to the workpiece. This prevents damage to the tool and potential overheating. Do not attempt to bypass or disable this safety feature.
- Disc Compatibility: Only use grinding and cutting discs with a diameter of 125 mm or 115 mm that are rated for the grinder's maximum RPM.

Operating Instructions
- Starting the Grinder:
With the battery inserted and disc securely mounted, hold the grinder firmly with both hands. Press the power switch to start the tool. Allow the disc to reach full speed before making contact with the workpiece.

- Stopping the Grinder:
Release the power switch to stop the tool. Wait for the disc to come to a complete stop before setting the grinder down or performing any adjustments.

- Disc Inspection: Before each use, inspect the grinding or cutting disc for cracks, chips, or excessive wear. Replace damaged discs immediately.
- Storage: Store the grinder in a dry, secure place, out of reach of children. Remove the battery when storing for extended periods.
