9. Determine the necessity of using special maintenance tools and
special maintenance material according to the practical situation
of maintenance. Use them on the necessary position, and go on
with the maintenance according to proper procedures.
10. To replace the fuse, check to see whether the rated current of
new fuse is correct. Do not exceed the rated current of the fuse,
or do not use the fuse with low rated current.
11. When jacking up or supporting the car, lift or support the car on
proper position with care.
a. If only jacking up the car in the front part or rear part, choke up the
wheel to ensure the safety.
b. After the car is jacked up, use frame to support it. It is dangerous to
conduct maintenance on the car that is only jacked up with one
screw jack, even for the minor maintenance that can be finished
quickly.
12. Paying attention to the following matters to avoid the damage
of components:
a. If it is not absolutely necessary, do not open the housing of the
ECU and the computers (if the IC terminals are touched, the IC
may have electrostatic damage).
b. When removing the vacuum tube, pull the end of the tube instead of
the central part of the tube.
c. When pulling the wire terminal, pull the terminal itself instead of
the wire.
d. Take care to not make the electrical components fallen, such as the
sensor or relay.
If they fall to the hard ground, they must be replaced.
e. Never use the striking wrench to remove or install the electric
thermostat or thermostat sensor.
f. When checking the conducting state of the wire connector, insert
the multimeter with care, do not bend the terminal.
g. When using the vacuum meter, do not insert the soft tube onto large
connector. Use the stepped terminal. Once the soft tube is swelled
and tightened, there may be leakage.
