2. General Safety Instructions
WARNING: Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.
2.1 Work Area Safety
- Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
- Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
- Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2.2 Electrical Safety
- Power tool plugs must match the outlet. Never modify the plug in any way.
- Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
- Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
2.3 Personal Safety
- Always wear eye protection. Use safety glasses, goggles, or a face shield.
- Wear hearing protection when operating power tools for extended periods.

4.3 Attaching the Base Plate and Dust Extraction
- The transparent base plate is pre-installed. Ensure it is clean and free of debris.
- To attach the dust extraction adapter, align it with the designated port on the base plate and secure it. This allows connection to an external vacuum cleaner for a cleaner work environment.

Figure 4: The transparent base plate provides visibility of the workpiece during operation. The dust extraction port is visible for connecting a vacuum.
4.4 Adjusting Milling Depth
- Loosen the depth adjustment lever.
- Rotate the fine adjustment knob to set the desired milling depth. The scale on the side indicates the depth in millimeters.
- Once the desired depth is set, tighten the depth adjustment lever to secure the router in position.
4.5 Attaching Guides (Parallel Stop, Compass Tip, Guide Roller)
Depending on your application, various guides can be attached to the router base for enhanced precision:
- Parallel Stop: Used for routing parallel to an edge. Slide the parallel stop into the slots on the router base and secure it at the desired distance from the bit.
- Compass Tip: For cutting perfect circles. Attach the compass tip to the base and pivot it around a central point.
- Guide Roller: For following curved edges or templates. Attach the guide roller to the base, ensuring it makes contact with the guide surface.
5. Operating Instructions
5.1 Powering On/Off
- To turn the router ON, slide the power switch to the 'I' position.
- To turn the router OFF, slide the power switch to the 'O' position.
5.2 Speed Control
The router features electronic infinitely variable speed control. Adjust the speed dial to match the material and router bit being used. Higher speeds are generally suitable for smaller bits and softer materials, while lower speeds are for larger bits and harder materials.

Figure 5: The speed control dial allows for precise adjustment of the router's RPM to suit different materials and applications.
5.3 Routing Techniques
- Always ensure the workpiece is securely clamped before routing.
- Start the router before making contact with the workpiece.
- Move the router smoothly and consistently along the desired path. Avoid sudden movements or excessive pressure.
- For best results and to prevent kickback, always feed the router against the direction of bit rotation.
- When routing edges, use the edge milling attachment for precise chamfering.
5.4 Dust Collection
For a cleaner work environment and improved visibility, connect a suitable wet/dry vacuum cleaner to the suction adapter. This helps to remove wood chips and dust during operation.
6. Maintenance
6.1 Cleaning
- Always disconnect the battery before cleaning.
- Regularly clean the router housing, base plate, and collet area to remove dust and debris. Use a soft brush or compressed air.
- Do not use aggressive cleaning agents or solvents.
6.2 Router Bit Care
- Keep router bits sharp and clean. Dull bits can cause overheating and poor cutting performance.
- Store bits in a protective case to prevent damage.
6.3 General Inspection
- Check all screws and fasteners regularly to ensure they are tight.
- Inspect the power cord (if applicable, for charger) for damage.
- Ensure all ventilation openings are clear to prevent overheating.
