6. Operating Instructions
Powering On/Off:

- To turn on, slide the On/Off switch to the 'On' position.
- To turn off, slide the On/Off switch to the 'Off' position. Always wait for the accessory to come to a complete stop before setting the tool down.
Speed Adjustment:
The EMGK1301 features variable speed control, allowing you to adjust the RPM from 10,000 to 35,000. Use lower speeds for polishing, delicate work, or when working with softer materials. Use higher speeds for grinding, cutting, or when working with harder materials.

- Start with a lower speed and gradually increase it as needed for the task and material.
General Usage Tips:
- Always hold the tool firmly with both hands if possible, especially during heavy-duty tasks.
- Apply light, consistent pressure. Do not force the tool, as this can lead to overheating or damage to the accessory/tool.
- Allow the tool to reach full speed before contacting the workpiece.
- For cutting, use a light touch and let the accessory do the work.

Cleaning:
