Automotive Servicing Safety Guide
All the information, explanations and detailed
descriptions in the operation manual have originated
from the industrial information recently published.
It is impossible to prove the accuracy and
completeness of the information, of which we shall
not be responsible for the assumption.
A. The data of the automotive servicing manual
have originated from the automotive servicing
information.
1. Contact the local distributors of automotive
components.
2. Contact the local retailers of automotive
components.
3. Contact the local libraries to look up any book
for the proofreading of your automotive servicing
manual so as to provide you with the latest
information.
B. Before the diagnosis of any trouble, open the
engine hood to make a thorough visual
inspection. You will find the causes for many of
your problems to be solved, which will save you
a lot of time.
1. Has the automobile recently been serviced? Has
the same problem sometimes occurred where
the trouble lies?
2. Do not try to find any short cut. Check the
hoses and leads where it is probably very
difficult to find out where any trouble lies.
3. Check any trouble with the air purifier or pipeline
system.
4. Check any damage to any sensor or the driving
gear.
5. Check the ignition lead: any breakage of any
terminal, crack on any spark plug or breakage
at the insulation of the ignition lead.
6. Check all the vacuum hoses: any right line,
shrinkage, bend, crack, fracture or damage.
7. Check the leads: any connection of sharp
edges, connection of hot surfaces (such as
exhaust manifold), shrinkage, burn or scratch
at the insulation or right line connection.
8. Check circuit connections: any pin corrosion,
bend or damage, inappropriate connection
position or damaged electrode lead.
