Hanboost C1 Ultrasonic Cutter

There are several reasons why the machine might not be cutting properly. It could be due to a drained battery, incorrect blade installation, or a potential malfunction with the machine. We recommend watching our tutorial video before using the machine to ensure proper setup and operation.

After installing the blade, turn on the machine and touch the blade to any metal surface. If you hear a sizzling sound, it means the machine is working correctly.

Check if the blade and blade holder are loose. Usually, tightening the screws will restore the normal operation of the machine.

Ultrasonic cutters use high-energy vibrations (about 40,000 times per second), so heating is normal. The machine is made with a metal body that offers excellent heat conductivity and dissipation. However, if used for extended periods, the heat can build up. The machine is equipped with a temperature sensor (NTC), and if the temperature reaches the set limit, the machine will automatically shut down for cooling.

When the machine is on setting 3, it operates at high power, which consumes the most energy. Typically, settings 1 and 2 consume less power.

Yes, you can,but not recommend. The machine supports charging via a 5V 2.5A power bank while in use. It also supports charging while cutting if the charger output is 5V 2.5A. However, for safety reasons, we don’t recommend doing this as it will reduce battery life.

The ultrasonic cutter operates through high-frequency vibrations that are typically too fast for the human eye to detect. Even though the blade is vibrating at high speed, the movement is so slight that it’s not visible. You can confirm the machine is working by feeling the vibrations or observing the cutting results.

Ultrasonic cutters work at a very high frequency. The high-frequency vibrations generate enough cutting force to penetrate harder materials like ABS and PVC. Paper, on the other hand, is soft and has a low density, so it tends to compress or bend during the cutting process. As a result, the cutting energy is not effectively transferred to the paper.

This could be caused by a few things:

1. Make sure the battery is charged and the blade is installed correctly.

2. Set the machine to the highest power setting (3) and let it activate for about 10 seconds.

3. If the issue persists after these steps, there may be a problem with the machine itself. In that case, please contact our customer service for assistance.

Material Cutting

✅ Recommended Materials

Material Example Uses Notes
PLA, ABS, PETG 3D printing models, plastic sheets Smooth cutting, works best at high power (Level 3)
PVC Pipes, thin boards Cuts cleanly, avoid thick industrial PVC
Acrylic (≤3mm) Small panels, crafts Ensure material is fixed to avoid vibration
Thin wood sheets, fiberboard DIY crafts, model making Works well for soft and thin wood
Leather, rubber Handicrafts, repairs Cut in slow, steady motion
Foam boards (EVA, craft foam) Prototyping, cosplay, model bases Easy cutting, minimal melting

⚠️ Not Recommended / Difficult to Cut

Material Why It's Not Recommended
Polystyrene (PS, foam board or solid) Heat-sensitive and porous → melts or compresses instead of cutting cleanly
Very hard plastics (e.g., PC, Nylon) Too tough → blade struggles, cuts very slowly
Metals (aluminum, steel, copper, etc.) Beyond ultrasonic cutter’s capacity
Thick hardwood Density too high, blade cannot penetrate effectively
Glass, ceramic Brittle → risks breaking blade and dangerous fragments

📝 Tips for Best Results

  • Always fix your material securely before cutting to prevent vibration.
  • Wait 5~10 seconds after power on (Level 3) for the blade to fully activate.
  • For plastics: cut slowly to avoid melting due to heat.
  • If unsure about a material, test with a small piece first.

Device Cannot Cut or Cuts with Weak Power

Possible Cause Explanation Suggested Solution
Blade not installed properly A loose or misaligned blade may reduce cutting performance Ensure the blade is tightly secured using the locking ring
Battery level too low Insufficient power may reduce ultrasonic vibration strength Charge the battery above 20% before use
Not waiting for ultrasonic activation The cutter needs a few seconds to reach full vibration Switch to level 3 and wait ~10 seconds before cutting
Material too soft or too elastic Ultrasonic energy may not effectively transfer to very soft materials Use a cutting mat or firm surface to support the material
Defective unit or transducer failure Internal issues may affect vibration or output power Contact customer support for inspection or replacement

🔊 Abnormal Noise – Common Causes & Solutions

Possible Cause Explanation Suggested Solution
Blade not tightened properly A loose blade can cause unusual vibration or metallic sounds Turn off the device and ensure the blade is securely fastened with the wrench
Blade is damaged or bent Deformed blades may produce noise during vibration Replace the blade with a new one
Material is too soft Soft materials like paper may not absorb vibration properly and cause unstable resonance Test with plastic or rubber first, then switch to your material
Low battery level Insufficient power may cause unstable vibration Charge the device to at least 30% and try again
Internal tuning not completed The device requires a short time to complete automatic frequency tracking Switch to power level 3 and let it run for 10 seconds before cutting

Device Cannot Power On

Possible Cause Explanation Suggested Solution
Battery completely drained The device cannot start with 0% battery Charge the device for at least 30 minutes, then try again
Power button not pressed correctly The button requires a long press to turn on Press and hold the power button for 2 seconds
Firmware not responding The device may require a reboot Connect charger and try to turn on after 1–2 minutes
Internal hardware fault There may be a damaged circuit or component Contact customer service for further support

Device Cannot Charge

Possible Cause Explanation Suggested Solution
Charging cable or adapter issue A faulty cable or incompatible adapter may prevent charging Try another USB-C cable and 5V adapter (≥2A)
Port connection not stable Debris or poor contact may affect the charging port Gently clean the USB-C port and ensure a tight connection
Battery management circuit abnormal The charging controller inside may not function properly Let the device cool down, then try charging again
Battery damage or aging Long-term storage or misuse can affect battery lifespan Contact support for battery replacement if needed

Battery Drains Too Quickly

Possible Cause Explanation Suggested Solution
High output level used continuously Level 3 consumes more power for stronger ultrasonic force Use level 1 or 2 for lighter tasks to conserve battery
Frequent on/off operations Power cycling uses more energy compared to steady use Avoid switching on/off frequently during work sessions
Battery aging or damage Battery health declines over time or improper storage Contact support for inspection or battery replacement
Charging not completed Partial charging may give inaccurate battery level readings Ensure full charge before usage (LED indicator fully on)
