The planing depth can be adjusted using the front knob. The depth can be set up to 3.5 mm.
- Rotate the depth adjustment knob located at the front of the planer.
- Align the desired depth setting with the indicator mark.
- A higher number indicates a deeper cut. Start with a shallow cut and gradually increase if needed.

- Power On: Plug the planer into a suitable power outlet.
- Starting the Planer: Press the safety button (if applicable) and then squeeze the trigger switch to start the motor. The safety button prevents accidental starts.
- Planing: Place the front shoe of the planer flat on the workpiece. Apply even pressure and move the planer smoothly and consistently across the wood surface.
- Chamfering: Use the V-grooves on the front shoe to create bevels on the edges of your workpiece. Position the V-groove over the edge and guide the planer along.
- Stopping the Planer: Release the trigger switch to stop the motor. Wait for the blades to come to a complete stop before setting the planer down. The safety foot will protect the blades and surface.
