High-pressure water entering connector
The connector is designed to make it difficult
q
for water to enter (drip-proof structure), but if
high-pressure water is sprayed directly on the
connector, water may enter the connector,
depending on the direction of the water jet.
Accordingly, 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
q
If any water, mud or dirt is stuck to the outside
surface of a connector, it can enter inside the
connector when the connector is discon-
nected. 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
q
and 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 contact. 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 con-
nector, 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 dirt-
ier. So, remove the oil and water from the
compressed air completely before clean-
ing the connector with the compressed air.

Disconnecting connectors
1.
Hold the connectors when disconnecting.
q
Disconnect connectors by holding the
connector bodies. For the connectors held
by a screw, loosen the screw fully, then
hold the male and female connectors with
each hand respectively and pull them
apart horizontally. For the connectors with
lock stopper, press down the stopper with
your thumb and pull the connectors apart.
a Never pull the connector with one
hand.
