Setup
Installing and Changing Router Bits
- Ensure the router is unplugged from the power source to prevent accidental startup.
- Press and hold the spindle lock button, typically located near the collet.
- Use the included collet wrench to loosen the collet nut by turning it counter-clockwise.
- Insert the desired router bit into the collet, ensuring at least 3/4 of the bit's shank is inserted for secure gripping.
- Firmly tighten the collet nut with the wrench by turning it clockwise. Do not overtighten, as this can damage the collet or bit.
- Release the spindle lock.
Adjusting Routing Depth
- Place the router on a flat surface with the desired bit installed and the router unplugged.
- Loosen the quick-release lever on the side of the router base.
- Lower the motor assembly until the router bit touches the workpiece surface.
- Use the micro-adjustment knob (featuring a zero reset) to set the precise desired depth. Each increment on the dial represents a fine adjustment for accuracy.
- Once the depth is set, firmly lock the quick-release lever to secure the motor assembly in place.

Operation
Basic Routing Techniques
- Ensure all safety precautions are followed, including wearing appropriate personal protective equipment (PPE).
- Verify the router bit is securely installed and the depth is correctly set for your application.
- Plug the router into a suitable power outlet.
- Hold the router firmly with both hands on the ergonomic handles, maintaining control.
- Start the router motor before making contact with the workpiece. Allow it to reach full speed.
- Guide the router smoothly along the desired path, applying steady, even pressure. Avoid forcing the tool, as this can lead to poor cuts or kickback.
- Always move the router in the correct direction relative to the bit's rotation to prevent kickback and ensure a clean cut.
- Turn off the router and allow the bit to stop completely before lifting it from the workpiece.
Maintenance
Cleaning
- Regularly clean the router, especially the collet and base, to remove sawdust, wood chips, and other debris.
- Use a soft brush or compressed air for cleaning. Avoid using solvents or harsh chemicals that may damage plastic components.
- Ensure the chip guard remains clear for optimal visibility and effective debris collection.
Bit Care
- Keep router bits sharp and clean for the best performance and safety. Dull bits can cause burning, splintering, and increased strain on the motor.
- Replace dull or damaged bits immediately. Never use bent or chipped bits.
Cord Inspection
- Periodically inspect the power cord for any signs of damage, such as cuts, abrasions, or fraying. Replace the cord if it is damaged.
