2.2 Specific Angle Grinder Safety
- Always use the guard provided with the tool. Ensure the guard is securely attached and positioned for maximum safety.
- Use only grinding wheels and cutting discs that are specifically designed for an angle grinder and are rated for the tool's maximum RPM.
- Bevestig het werkstuk. Gebruik clamps or a vise to hold the workpiece firmly. This frees both hands to operate the tool safely.

Align the guard with the grinder head and snap it into place, ensuring it is securely fastened and positioned to deflect sparks and debris away from you.
4.3 Installing Grinding/Cutting Discs
- Ensure the battery is removed from the grinder.
- Houd de spindelvergrendelingsknop op de slijpkop ingedrukt.
- Plaats de binnenflens op de spindel.
- Position the desired grinding or cutting disc onto the spindle, ensuring it sits flush against the inner flange.
- Place the outer flange onto the spindle, on top of the disc.
- Use the provided spanner to tighten the outer flange clockwise until the disc is securely fastened. Release the spindle lock.
4.4 De batterij opladen
Before first use, fully charge the 4.0Ah Lithium-Ion battery. Connect the fast charger to a standard power outlet. Slide the battery pack onto the charger until it clicks into place.

5.2 Slijpbewerkingen
For grinding tasks, ensure the grinding wheel protector is installed and a grinding disc is securely attached. Hold the grinder firmly with both hands, maintaining a stable stance. Apply light, even pressure to the workpiece, allowing the 7500 RPM speed to do the work. Move the grinder smoothly across the surface to achieve desired results. The tool's lightweight design (3.5 pounds without battery) helps reduce hand pressure during extended use.

5.3 Snijbewerkingen
When cutting, use the cutting wheel protector and a suitable cutting disc. Position the workpiece securely. Start the grinder before making contact with the material. Guide the disc through the material with steady, controlled movements. Avoid twisting or binding the disc, which can cause kickback. The tool's ergonomic design and rubberized grip provide a better user experience during cutting tasks.
