When installing a servo arm and securing it with the mounting screw, apply only a very small amount of threadlocker (such as Loctite) to the threads near the screw head only.

Inside the servo, directly beneath the output gear where the servo arm is mounted, there is a position sensor.

If excessive threadlocker is applied, it may flow into the gear area.

In addition, vapors released during the curing process may migrate into the sensor assembly and form a thin film on the sensor components.

This can interfere with the sensor’s operation and may result in servo malfunction or failure.

To prevent this, please ensure that:

・Only a minimal amount of threadlocker is used

・Threadlocker is applied only to the threads near the screw head

・Threadlocker is not allowed to reach the lower threads or internal components of the servo

Proper application will help ensure reliable servo performance and prevent potential damage.
