Setup
Before attaching any accessory, ensure your rotary tool is unplugged or its battery is removed to prevent accidental activation. Always wear appropriate safety gear, including eye protection.
1. Selecting the Correct Collet:
The kit includes four collets: 1/16" (1.6mm), 3/32" (2.3mm), and two 1/8" (3.2mm). Choose the collet that matches the shank size of the accessory you intend to use. The correct collet ensures a secure fit and prevents wobbling during operation.

2. Attaching Accessories:
- Insert the appropriate collet into the rotary tool's collet nut.
- Insert the accessory shank into the collet. Ensure the accessory is inserted as far as possible without the flutes or abrasive part touching the collet nut.
- Tighten the collet nut using the included spanner/wrench. Do not overtighten, but ensure the accessory is held firmly. For accessories like sanding bands, grinding wheels, or felt wheels that require mandrels, first attach the abrasive part to the mandrel, then insert the mandrel into the collet.

Operating Instructions
Always match the accessory to the task and material. Start with a lower speed setting on your rotary tool and gradually increase it as needed. Avoid applying excessive pressure, as this can damage the accessory or the workpiece.
General Applications:
- Cutting: Use cut-off wheels (fiberglass, heavy-duty, or standard) for cutting metal, plastic, or other materials. The diamond cutting wheel is suitable for harder materials.
- Sanding: Utilize sanding papers, sanding bands, or flap wheels for smoothing surfaces on wood, metal, plastic, or stone.
- Grinding/Sharpening: Employ grinding wheels, alumina grinding stones, silicon carbide grinding stones, or rubber emery wheels for shaping, deburring, or sharpening tools and materials.
- Carving/Engraving: Diamond grinding drills and HSS grinding points are ideal for detailed work on wood, metal, stone, glass, and other materials.
- Polishing/Cleaning: Use felt wheels, felt wheel points, and polishing compound for achieving a high-gloss finish. Brass, steel, and nylon brushes are effective for cleaning and surface preparation on various materials.
- Drilling: HSS drill bits are included for precision drilling in wood, metal, plastic, and glass.

Maintenance
1. Cleaning Accessories:
After each use, clean accessories to remove debris and residue. Brushes can be cleaned with appropriate solvents if necessary. Abrasive accessories like sanding bands and grinding wheels should be inspected for wear and replaced when dull or damaged.
2. Storage:
The kit comes with a durable, transparent storage case designed to keep all accessories organized. Store the accessories in this case in a dry, moisture-free environment to prevent rust and damage. The case is also waterproof and moisture-proof, offering protection for the contents.

Troubleshooting
Most issues with rotary tool accessories relate to improper selection, attachment, or usage. Refer to the following common issues:
- Accessory Wobbles or Vibrates: Ensure the correct collet size is used and the collet nut is securely tightened. The accessory should be inserted fully into the collet.
- Poor Performance (e.g., slow cutting, ineffective sanding): Verify that the accessory is suitable for the material and task. Check if the accessory is worn out or dull and replace if necessary. Adjust the rotary tool's speed to match the application.
- Accessory Breaks Easily: Avoid applying excessive pressure. Ensure the rotary tool speed is appropriate for the accessory and material. Some accessories, like thin cut-off wheels, are inherently fragile and require careful handling.
If problems persist, consult your rotary tool's manual for specific guidance related to the tool itself.
