2. Safety Instructions
Always observe basic safety precautions when using electric power tools to reduce the risk of fire, electric shock, and personal injury. Read all instructions before operating this tool.
- Work Area Safety: Keep your 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.

4. Setup
4.1. Unpacking and Inspection:
Carefully remove all contents from the packaging. Inspect the router and all accessories for any signs of damage. If any damage is found, do not operate the tool and contact customer service.
4.2. Installing a Router Bit:
- Ensure the router is unplugged from the power source.
- Press and hold the spindle lock button.
- Insert the shank of the desired router bit into the collet. Ensure the bit is inserted as far as possible to provide maximum grip and minimize runout.
- While holding the spindle lock, use the collet wrench to tighten the collet nut securely. Do not overtighten.
- Release the spindle lock.
4.3. Adjusting Depth:
- Place the router on a flat surface with the bit touching the surface.
- Loosen the base clamp lever.
- Adjust the router body up or down until the desired bit depth is achieved using the depth scale.
- Tighten the base clamp lever firmly to secure the depth setting.
5. Operating Instructions
5.1. Powering On/Off:
To turn the router ON, slide the red power switch to the 'I' position. To turn it OFF, slide the switch to the 'O' position.
5.2. Adjusting Variable Speed:
The router features a variable speed dial. Rotate the dial to select the appropriate RPM for your material and bit type. Lower speeds are generally used for larger diameter bits, harder materials, or when more control is needed. Higher speeds are suitable for smaller bits and softer materials.
5.3. Routing Techniques:
- Workpiece Securement: Always secure your workpiece firmly with clamps before routing to prevent movement.
- Direction of Feed: For most operations, feed the router against the rotation of the bit. This provides better control and a cleaner cut.
- Multiple Passes: For deeper cuts, make several shallow passes instead of one deep pass. This reduces strain on the tool and bit, and improves cut quality.
- Edge Trimming: Utilize the straight edge guide (if applicable) or the router's base to maintain a consistent distance from the edge of the workpiece. The finger support pockets can aid in stability during this process.
6. Maintenance
6.1. Cleaning:
After each use, unplug the router and use a brush or compressed air to remove dust and debris from the motor vents and base area. Do not use solvents or harsh chemicals.
6.2. Router Bit Care:
- Clean bits regularly to remove resin and pitch buildup, which can cause overheating and poor cuts.
- Store bits in a protective case to prevent damage to the cutting edges.
- Replace dull or damaged bits immediately to ensure safe and effective operation.
6.3. Cord Inspection:
Periodically inspect the power cord for any cuts, abrasions, or damage. If damaged, have it repaired by a qualified service technician.
