Setup and Assembly
Before first use, ensure all components are present as listed in the kit contents. The Dremel 4000-2/30 kit includes the rotary tool, two attachments (678-01 Circle Cutter/Straight Edge Guide and A576 Sanding/Grinding Guide), and 30 accessories.
Attaching Accessories
To attach an accessory:
- Press and hold the shaft lock button located on the tool's head.
- Unscrew the collet nut.
- Insert the accessory shank fully into the collet.
- While still holding the shaft lock button, tighten the collet nut securely using the provided wrench or the EZ Twist nose cap. Ensure the accessory is firmly seated before operation.
For accessories like sanding bands, use the handle of the provided wrench as a screwdriver to loosen the small screw on the sanding tip, swap the band, and then tighten it securely.


Attaching Guides
The kit includes two useful attachments:
- A576 Sanding/Grinding Guide: Supports use on both flat and angled surfaces, allowing for sharpening, grinding, and sanding at accurate 45° or 90° angles. It features 3/4" (2 cm) adjustable depth control.
- 678 Circle Cutter & Straight Edge Guide: Enables cutting or routing of 0.75" - 12" (2 cm - 30 cm) diameter circles, and cutting or routing of 0.4" - 4.33" (1 cm - 11 cm) wide straight lines.


Operation
The Dremel 4000 offers variable speed control from 5,000 to 35,000 RPM, allowing you to select the optimal speed for each application and material. The electronic feedback circuitry ensures consistent performance even under load.
Speed Control
Use the separate speed dial to adjust the rotational speed. A lower speed is generally recommended for polishing, delicate work, or when working with softer materials to prevent burning or damage. Higher speeds are suitable for cutting, grinding, and harder materials.
Applications
The Dremel 4000 is ideal for a variety of tasks:
- Cutting: Use appropriate cutting wheels for materials like metal, plastic, or tile.
- Detail Sanding: Utilize sanding bands and discs for fine finishing on wood, metal, and other surfaces.
- Engraving: Engraving cutters can be used for detailed work on various materials.
- Wood Carving: Carving bits allow for intricate designs and shaping in wood.
- Polishing: Polishing wheels and compounds can restore shine to metal and other surfaces.
- Grinding/Sharpening: Grinding stones are effective for sharpening tools or smoothing rough edges.


Maintenance
Regular maintenance ensures the longevity and optimal performance of your Dremel 4000 rotary tool.
Cleaning
After each use, wipe down the tool with a clean, dry cloth. Ensure the ventilation slots are clear of debris to maintain proper airflow and prevent overheating.
Motor Brush Replacement
The Dremel 4000 features replaceable motor brushes, contributing to its extended tool life. Refer to the detailed instructions in the full user manual for guidance on inspecting and replacing the carbon brushes when they wear down.

Troubleshooting
If you encounter issues with your Dremel 4000, consider the following common solutions:
- Tool Slows Down or Jerks Under Load: This may indicate that the speed setting is too low for the material or task, or that the motor brushes are worn and need replacement. Increase the speed or check the brushes.
- Material Burning: If the material (especially wood) burns during operation, the speed setting might be too high, or you might be applying too much pressure. Reduce the speed and apply lighter pressure.
- Excessive Vibration: Ensure accessories are properly seated and tightened in the collet. An improperly installed accessory can cause vibration. If the issue persists, check for worn motor brushes.
- Sparks from Ventilation: A small amount of sparking is normal, especially when the tool is new or under heavy load. However, excessive sparking may indicate worn motor brushes that require replacement.
For persistent issues not resolved by these steps, please refer to the full user manual or contact Dremel customer support.
