5. Setup

5.1 Charging the Device

1. Connect the provided Type-C power cable to the charging port on the cutter.
2. Connect the other end of the cable to a compatible 12V power adapter (not included) or a USB power source.
3. The high-definition display will indicate the charging status. Ensure the device is fully charged before first use for optimal performance.

5.2 Blade Installation

1. Ensure the device is powered off and disconnected from any power source.
2. Carefully remove the protective blade cap.
3. Loosen the blade retention screw (if present) or mechanism at the tip of the cutter.
4. Insert a new alloy blade tip into the designated slot, ensuring it is seated firmly and correctly oriented.
5. Secure the blade by tightening the retention screw or mechanism. Do not overtighten.
6. Replace the protective blade cap when the cutter is not in use.

6. Operating Instructions

6.1 Powering On/Off

• To power on, press and hold the power button (usually marked with a ⑂ symbol) until the display illuminates.
• To power off, press and hold the power button again until the display turns off.

6.2 Selecting Cutting Modes

The FS-S1 offers three adjustable cutting modes to suit different materials:

1. After powering on, press the 'M' button (Mode button) to cycle through the available modes.
2. The high-definition display will show the current mode:
   • Gentle (L1): For delicate materials or fine trimming, such as thin paper or soft plastics.
   • Standard (L2): General purpose mode for materials like wood, thicker paper, and some 3D print models.
   • Strong (L3): For tougher materials such as carbon fiber laminates, plexiglass, PCBs, and leather.
3. Select the appropriate mode for your material to ensure efficient cutting and prevent damage to the blade or workpiece.

6.3 Cutting Technique

1. Place the material to be cut on a stable, protective surface.
2. Hold the cutter firmly with a comfortable grip, ensuring your fingers are clear of the blade.
3. Gently apply the blade tip to the material at the desired cutting line.
4. Apply light, consistent pressure and guide the cutter along the line. Allow the ultrasonic vibrations to do the cutting; excessive force is not required and can damage the blade or material.
5. For thicker materials, multiple passes with light pressure may be more effective than a single forceful pass.
6. Utilize the auxiliary light for improved visibility in intricate cutting tasks.
