5. Instruccions de funcionament
This section details how to operate your VONROC Radial Miter Saw for various cutting tasks.
5.1 Funcionament bàsic

Figure 5.1: User operating the VONROC Radial Miter Saw. This image illustrates the saw in action, with a user carefully guiding the blade through a wooden workpiece, demonstrating a typical cutting scenario.
- Place the workpiece firmly against the fence and secure it with the workpiece clamp.
- Ensure the blade guard is functioning correctly.
- Switch on the laser guide and LED light for improved visibility and cut line indication.
- Start the saw using the power switch. The soft start electronics will ensure a smooth power-up.
- Slowly lower the saw head into the workpiece, allowing the blade to reach full speed before making contact.
- Push the saw head through the workpiece at a controlled, steady rate.
- Once the cut is complete, release the power switch and allow the blade to stop completely before raising the saw head.
5.2 Miter Cuts
Miter cuts are angled cuts across the face of the workpiece.

Figure 5.2: Miter angle adjustment on the saw. This image shows the saw's turntable being rotated to set a miter angle, with an arrow indicating the range of motion from -45° to +45°.
- Afluixeu la maneta de bloqueig de la mitra.
- Rotate the turntable to the desired miter angle (e.g., 0°, 15°, 22.5°, 30°, 45°).
- Lock the turntable securely in place.
- Proceed with the cut as described in Basic Operation.
5.3 talls de bisell
Bevel cuts are angled cuts through the thickness of the workpiece.

Figure 5.3: Bevel angle adjustment on the saw. This image illustrates the saw head tilting to set a bevel angle, with an arrow indicating the 0° to 45° range of motion.
- Afluixeu el botó de bloqueig del bisell.
- Tilt the saw head to the desired bevel angle (up to 45°).
- Lock the saw head securely in place.
- Proceed with the cut as described in Basic Operation.
5.4 Compound Cuts
Compound cuts involve both a miter and a bevel angle simultaneously.
- Set the desired miter angle as described in Section 5.2.
- Set the desired bevel angle as described in Section 5.3.
- Ensure both angles are securely locked.
- Proceed with the cut as described in Basic Operation.
5.5 Using the Laser Guide and LED Light

Figure 5.4: Close-up of the laser guide and LED work light. This image highlights the integrated laser projecting a red line for cut guidance and the LED light illuminating the cutting area for enhanced precision and visibility.
The integrated laser projects a clear line onto your workpiece, indicating the exact cutting path. The LED light illuminates the work area, which is particularly useful in dimly lit environments. Activate these features using their respective switches before starting a cut.
6. Manteniment
