2. Slide the battery into place until it clicks securely.
3. To remove, press the release button on the battery and slide it out.

Figure 2: Illustration indicating that the battery and charger are not included with the tool and must be purchased separately.

4.2 Disc Installation and Guard Adjustment

The angle grinder accepts cutting discs up to 125 mm in diameter.

1. Ensure the tool is switched off and the battery is removed.
2. Press and hold the spindle lock button.
3. Unscrew the quick-fix nut by hand (or using a spanner if necessary, though it's designed for tool-free operation).
4. Place the desired grinding or cutting disc onto the flange, ensuring it is centered.
5. Screw the quick-fix nut back on and tighten it firmly by hand. Release the spindle lock button.
6. Adjust the quick-adjust disc guard to ensure maximum protection for your hands and body, deflecting sparks away from you.

5. Operating Instructions

5.1 Powering On/Off

1. To switch on, slide the ON/OFF switch forward.
2. To switch off, release the ON/OFF switch. The tool will stop.

5.2 Variable Speed Control

The integrated variable speed control allows you to adjust the rotational speed between 3000 and 10500 RPM, optimizing performance for different materials and applications. The constant electronics feature ensures that the selected speed is maintained even under load.

1. Use the speed control dial to select the desired RPM.
2. Refer to the LED speed display for the current setting.
3. Lower speeds are generally suitable for polishing or working with sensitive materials, while higher speeds are for aggressive grinding and cutting.

5.3 General Usage Tips

• Allow the tool to reach full speed before contacting the workpiece.
• Apply moderate pressure; excessive force can lead to overheating, reduced performance, and disc damage.
• Move the tool smoothly and consistently across the workpiece.
• For cutting, use a cutting disc and make shallow passes to avoid binding.
• For grinding, hold the disc at a slight angle to the workpiece.
