High-pressure water entering connector
The connector is designed to make it difficult for
q
water to enter (drip-proof structure), but if high-
pressure water is sprayed directly on the con-
nector,
water
may
depending on the direction of the water jet. Ac-
cordingly, take care not to spray water over the
connector.
The connector is designed to prevent water from
entering, but once water does enter, it is difficult
to drain it. If water should get into the connector,
the pins will be short-circuited by the water. So if
any water gets in, immediately dry the connector
or take other appropriate action before passing
electricity through it.
Entry of water, mud or dirt when disconnecting
a connector
If any water, mud or dirt is stuck to the outside
q
surface of a connector, it can enter inside the
connector when the connector is disconnected.
Before disconnecting the connector, wipe off any
stuck water or dirt by using a piece of dry cloth or
blow it with compressed air.

Oil, mud or dirt stuck to connector
If any oil or grease is stuck to the connector and
q
an oil film is formed on the mating surface of the
male and female pins, the oil prevents electricity
from passing through, resulting in defective con-
tact. If any oil or grease, mud or dirt is stuck to
the connector, wipe it off with a dry cloth or blow
it with compressed air and spray it with electrical
contact restorer.
a When wiping the joint portion of the connec-
tor, be careful not to apply excessive force or
deform the pins.
a If there is oil or water in the compressed air,
it causes the contacts to become dirtier. So,
remove the oil and water from the com-
pressed air completely before cleaning the
connector with the compressed air.
