3. Setup and Assembly

Before operating the rotary tool, ensure proper setup and accessory attachment.

3.1 Attaching Accessories

1. Power Disconnection: Always ensure the tool is unplugged from the power source before changing accessories.
2. Keyless Chuck: The universal keyless chuck allows for quick accessory changes without collets. To insert an accessory, press the spindle lock button, loosen the chuck by rotating it counter-clockwise, insert the accessory shank fully, and then tighten the chuck by rotating it clockwise. Release the spindle lock button.
3. Collets (if applicable): For accessories requiring a collet, ensure the correct size collet (e.g., Ø3.2mm) is inserted into the collet nut, then into the tool. Insert the accessory, press the spindle lock, and tighten the collet nut with the provided spanner.
4. Flexible Shaft: To attach the flexible shaft, unscrew the collet nut and collet from the main tool. Screw the flexible shaft's coupling nut onto the tool's threaded shaft until secure. Insert the desired accessory into the flexible shaft's chuck and tighten.
5. Protective Shield/Wheel Guard: For cutting or grinding operations, attach the wheel guard by sliding it over the tool's head and securing it in place. Ensure it provides adequate protection for the specific task.

4. Operating Instructions

This section provides guidance on operating your rotary tool for various applications.

4.1 Power On/Off and Speed Control

• Power On: Plug the tool into a 120V AC power outlet. Press the safety switch to the 'ON' position.
• Speed Adjustment: Use the 6-level variable speed dial to select the desired RPM, ranging from 10,000 RPM to 35,000 RPM. Start with a lower speed for delicate tasks and increase as needed for harder materials or more aggressive removal.
• Power Off: Press the safety switch to the 'OFF' position and unplug the tool when not in use.

4.2 Application-Specific Guidance

• Cutting (Glass & Metal):

  Use cut-off wheels for wood and metal. For stone, ceramics, or floor tiles, utilize the diamond cutting disc. Important: Always get the diamond disc wet to prolong its service life and use a protective cover (wheel guard) to ensure safety during cutting operations.

  

• Sanding & Polishing:

  Select abrasive stones, felt wheels, sanding drums, or sanding discs based on the material and desired finish. These accessories help smooth surfaces, remove rough spots, clean rust from steel, or strip paint from boards.

  

  

• Wood Carving & Routing:

  Utilize multi-purpose cutting bits, diamond grinding needles, or engraving cutters for detailed work on wood and other materials. The flexible shaft attachment is particularly useful for intricate carving and engraving tasks, offering enhanced control and maneuverability.
