resulting in electric shock or breakdown.)
- If you wish to use the product outdoors or in any other location exposed to rainwater or other forms of
moisture, protect the wiring conduit of the actuator against ingress of rainwater and all other wetness.

similar, resulting in electric shock or breakdown.)

despite an abnormality present may result in a fire. If you detect any abnormalities, be sure to consult
the dealership where you bought the product or our service station nearest your premises and ask them
to perform an inspection.)
