Accordingly, take care not splash water over the connector.
The con- nector is designed to prevent water from entering, but at the same time, if water does enter, it is difficult for it to be drained. Therefore, if water should get into the con- nector, the pins will be short-circuited by the water, so if any water gets in, immedi- ately dry the connector or take other appropriate action before passing electric- ity through it. 5) Oil or dirt stuck to connector If oil or grease are stuck to the connector and an oil film is formed on the mating sur- face between the male and female pins, the oil will not let the electricity pass, so there will be defective contact.
If there is oil or grease stuck to the connector, wipe it off with a dry cloth or blow it dry with com- pressed air and spray it with a contact restorer. a When wiping the mating portion of the connector, be careful not to use excessive force or deform the pins. a If there is oil or water in the com- pressed air, the contacts will become even dirtier, so remove the oil and water from the compressed air com- pletely before cleaning with com- pressed air.
