User Guide & Precautions

• Confirm the power supply voltage is within 3.0V-7.2V before wiring to avoid servo damage from overvoltage.
• Do not forcefully tighten the servo horn during installation to prevent damage to plastic gears or the output shaft.
• Perform center calibration before first use to ensure control signals match the servo travel range for better precision.
• This is a beginner-level plastic gear servo. It is not recommended for high-torque heavy-load applications to avoid gear stripping.
• If the servo experiences jamming, abnormal noise or no response, stop using immediately and check the wiring and power supply.
