●Do not maintain the maximum torque output for an extended period of time.

The maximum indicated torque output of this product is only intended for short periods of time. It is not recommended to use this product 
in a state of maximum torque output for extended periods of time. Please consider this when designing your robots.

●Avoid frequent repetitive movements.

Rotating the servo back and forth a lot in a short period of time will cause excess heat to build up and may result in damage to the product.

●Ensure each servo receives enough power when connecting in a daisy chain pattern.

Theoretically, this product can be daisy chained up to 32 units. Daisy chaining this product may result in a weakened signal, a lack of 
power, or wiring burning out. When daisy-chaining this product, we recommend running a separate signal wire and power wire with sufficient 
capacity to power the servos.  This is to reduce the chance of a weak signal as a consequence of a loop connection.

Precautions for Use

●Keep all body parts away from this product during operation. Always pay attention while operating this product.

This product is designed for use in robots. It cannot be used in other 

products such as radio controlled cars.

Please check that the servos move freely through their range of motion when 

installing into your robot. Backlash or looseness in bracketing may cause an 
unnecessarily high load on the servos, increasing power consumption and 
reducing the lifespan of the product. 

Dry cell batteries may not be sufficiently powerful enough to operate this 

product. 

The maximum range of motion this product is capable of will depend on the 

input signal. 

Take extra care when attempting to use home-built control 

boards to control these servos.Use under extreme conditions 
may result in under performance and a heavily reduced 
life-span of this product.If you have questions relating to the 
use and/or output of this product, please visit our website at 
http://www.kondo-robot.com. If you cannot find the information 
you require, contact our service department with your inquiry. 
Please note that we are cannot answer questions on control 
programming. Thank you for your understanding.

● Check the input signal and source voltage before 
    operating this product.
● Pay attention to the orientation of the connectors, and 
    ensure they are correctly plugged in.
● Do not use this product in a place where there it may get 
    wet.

● Do not dismantle or modify this product in a way   
    that is not endorsed by this company. 

  ※Do not use signals or voltages outside the specified range. Doing so may result in 
       malfunction or damage to the product.
  ※Reversal of the polarity of the power source will damage the product.
  ※Allowing water to get inside this product may cause damage and/or malfunction.
