Handling of electrical equipment
2. When removing from clips
q
Both of the connector and clip have stop-
pers, which are engaged with each other
when the connector is connected.
q When removing a connector from a clip,
pull the connector in a parallel direction to
the clip for removing stoppers.
a
If the connector is pried up and down
or to the right and left, the housing
may break.
3. Action to take after removing connectors
q After removing the connector, cover it with
the vinyl bag to prevent entry of dust,
dirt,oil or water in the contact portion.
a
If the machine is left disassembled for
a long time, it is particularly easy for
improper contact to occur, so always
cover the connector.
Connecting connectors
1. Check the connector visually.
q Check that there is no oil, dirt or water
stick to the connector pins (joint portion).
q Check that the connector pins are free
from deformation, defective contact, corro-
sion, or damage.
q Check that external surfaces of the con-
nectors are free from damage or break-
age.
a
If any oil, water or dirt is stuck to the con-
nector, wipe it off with a dry cloth. If any
water is inside the connector, warm the
connector and the inside of the wiring har-
ness with a dryer. But be careful not to
make it too hot as it causes short circuit.
a
If there is any damage or breakage,
replace the connector.
2. Fix the connector securely.
q Align the connectors correctly, and fit them
securely. For the connectors with the lock
stopper, push in the connectors until
“click” is heard.
3. Correct the protrusion of the boot and mis-
alignment of the wiring harness
