GENERAL INFORMATION
GENERAL INSTRUCTION
This publication is designed to help you the body repair technician with your specialized work. Vehicle
bodywork has changed a great deal over the years. As vehicles have developed technically, vehicle
bodywork has also had to meet new requirements with design, changes to reconcile apparently
conflicting demands to name just a few examples:
• strength and safety ; low weight
• spaciousness ; good aerodynamics
• high quality ; low price
The durability and ease of repair of the bodywork also plays an important part.
Nowadays, the use of highly automated production equipment makes it possible to maintain the tightest
tolerances and thus ensure a high level of quality.
When bodywork is damaged, the customer rightly expects it to be expertly repaired to the same quality
standards.
At the same time, for his safety, the customer expects you to have comprehensive knowledge of
materials, measuring and straightening methods, possible distortion, optimum corrosion prevention and
much more besides.
This publication is designed to help you update your knowledge and give you an idea of what you require
to rectify moderate or severe accident damage, for your own safety and for the satisfaction of your
customers.
IMPORTANT SAFETY NOTICE
BEFORE BEGINNING WORK
◦ Disconnect the battery to reduce the possibility of fire caused by electrical shorts.
◦ Check for fuel leaks and repair as necessary.
◦ Remove the fuel tank and/or fuel lines if welding equipment is to be used near the
fuel system.
◦ Before welding, sanding or cutting, protect carpets and seats with fire-proof
covers.
◦ Follow standard safety practices when using toxic or flammable liquids.
◦ Use standard safety equipment when spraying paint, welding, cutting, sanding or
grinding. Standard safety equipment includes.
◦ Respirator and filter masks: Designed to filter out toxic fumes, mist, dust or other
airborn particles. Use a respirator or filter mask designed to protect you from the
hazards of the particular job; some respirators, for example, are designed to filter
out only dust and airborn particles, not toxic fumes.
◦ Safety goggles or glasses: Designed to protect your eyes from projectiles, dust
particles or splashing liquid.
◦ Gloves: Rubber gloves protect against corrosive chemicals. Welding gloves
protect against burns and abrasions caused by welding, sanding or grinding.
◦ Safety shoes: Non-slip soles protect against slipping. Metal toe inserts protect
against falling objects.
◦ Ear plugs: Protect eardrums from harmful noise levels.
DURING WORK
◦ Do not smoke while working near the fuel system.
◦ Deposit gas or solvent-soaked shop towels in an approved container.

4. ◦ Brake lining contains asbestos, which can cause cancer. Do not use an air hose to
blow off brake assemblies: use only an approved vacuum cleaner, and wear an
approved filter mask or respirator.
◦ Always attach a safety cable when using a hydraulic ram or a frame straightening
table: do not stand in direct line with the chains used on such equipment.
BODY SAFETY
Modern stressed-skin bodies are designed so as to have a sturdy passenger cell protected by front and
rear crumple zones.
• In an accident the crumple zones are designed to convert impact energy into deformation
work.
• The shape, material and metal thickness must all be precisely matched.
• Many years of experience, refined computational methods and expensive series of crash tests
mean that DAEWOO now builds bodies giving optimum deformation in the crumple zones in
frontal or rear impacts.
When repairing body damage, it is therefore imperative to restore the original structure and strength in
order to guarantee the safety of the occupants.
LOADS ON BODY PARTS
• The earlier practice of making a distinction between load bearing and non-loading bearing
parts of vehicles with a chassis and body is no longer justified now. Every part, even the
windows, contributes to the overall strength of the vehicle.
THEREFORE, WITH MODERN DAEWOO BODIES, ONE TALKS OF HIGHLY STRESSED AND LESS
HIGHLY STRESSED PARTS.

5. USE OF NEW HIGH-QUALITY MATERIALS
• The requirement for reduced body weight has lead to a reduction in the amount of steel used,
e.g. through the use of thinner sheet steels.
This has been achieved with HIGH STRENGTH SHEET STEELS, in spite of the need to meet higher
body strength requirements at the same time.
High strength steels have a tensile strength and a yield strength as much as 30% higher than
conventional steel. These properties must not be destroyed when carrying out repairs, e.g. by using
excessive heat.
CORROSION PROTECTION
• The durability of the bodywork, its associated long-term safety and retention of value largely
depend on the corrosion protection given to the sheet metal. Here, DAEWOO takes a great
deal of care in production.
• Therefore, this corrosion protection must be preserved or restored when repairs are carried
out.
SUMMARY
• All DAEWOO vehicles are built to the highest standards in terms of styling and material
properties.
• These high quality standards must be maintained when accident repairs are carried out.
• Mistakes made when carrying out repair operations such as straightening, welding sheet-
metal parts, etc. not only produce visible defects, but may also compromise the safety of the
vehicle.
• Mistakes made when restoring the corrosion protection compromise durability.
ZINC TREATED STEEL PLATE REPAIR
The zinc plated steel plate used in some panels of the LANOS requires different repair techniques than
ordinary steel plate.
1. Before spot welding the zinc plated steel plate, remove the paint from both sides of the flange
to be welded. Apply sealer to the flange after welding.

6. Caution : To prevent eye injury, wear goggles or safety glasses whenever sanding,
cutting or grinding.
Note : Seal the sanded surfaces thoroughly to prevent rust.
2. The electric continuity properties of zinc plated steel plate is different from ordinary steel plate.
When spot welding, increase the current by 10-20%, or increase the resistance welding time.
Increase the number of weld spots by 10-20% also.
Note : The MIG welding procedures for zinc plated steel plate are the same as for
ordinary steel plate.
Caution : To prevent eye injury and burns when welding, wear an approved welding
helmet, gloves and safety shoes.
3. Before applying putty or body filler to the zinc plated steel plate, sand the zinc plating
thoroughly to promote adhesion and prevent blistering.
Note : Use only epoxy-based putties and fillers on zinc plated steel plate.

PREPARATIONS OF BODYWORK
GENERAL DESCRIPTION
• Most monocoque bodies are composed as a single unit by welding together pressed parts
made of steel plates which come in a variety of different shapes and sizes. Each part is
responsible for displaying a certain strength and durability in order that it may play its role in
meeting the functions of the body as a whole.
Damage to the exterior of the body can be inspected visually, but where there has been an external
impact, it is necessary to inspect the extent of the damage. In some cases, the deformation has spread
beyond the actual areas which were in the collision and so this has to be inspected closely.

16. MEASURING SYSTEMS (WITHOUT SMALL DAMAGE)
• Whenever possible, make judgements and conclusions based on measurement. Measure the
wheel alignment(see pages 2-2, 2-3) so as to prevent any future trouble like unsymmetrical
wear of the tires or catching of the steering wheel.
• If there are any deviations, use a tram tracking gauge and measure parts of the body.(Below
Fig. 4-1)
• If there is any twisting to the body, measure using a frame centering gauge.(Below Fig. 4-2)
