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.
