paint after paint repair
Hardening of insulation due
to contact with an
incompatible agent (e.g.
solvent)
Line open circuit, contact
pairing not longer conductive
(transition resistances)

Safety precautions/instructions
Wear protective clothing, safety glasses and heat-resistant gloves.
Transport hot or glowing objects using approved equipment only.
When handling glowing objects, avoid sparks and keep objects away from flammable materials and
substances.
First aid measures
Flush the affected skin areas with plenty of cold water and dress with sterile bandages.
Consult a doctor without delay.
RISK OF DEATH. DEATH MAY OCCUR IF BODY PARTS ARE DRAWN INTO ROTATING VEHICLE PARTS. - AS00.00-Z-
0004-01A
Do not reach into rotating parts.
Wear closed and snug-fitting work clothes.
Secure area near rotating vehicle parts against unauthorized access.
Risk of death
Freely rotating parts near the running engine and around the drive train can cause serious injuries .
During all work on rotating driven axles the opposite wheel hub spins in rotation as well. This produces a blind
hazard area that must be protected from unauthorized access.
Safety instructions/precautions
Wear closed and snug-fitting work clothes.
Remove all items of jewelry, such as chains, rings, etc.
Restrain long hair by wearing an appropriate head cover.
Set up appropriate shielding (e.g. barrier, safety guard) to secure blind hazard areas against unauthorized
access.
RISK OF ACCIDENT & RISK OF INJURY - AS00.00-Z-0005-01A
Secure vehicle to prevent it from moving off by itself.
Wear closed and close-fitting work clothes.
Do not grasp hot or rotating parts.

Risk of accident
from vehicle starting off during starting operation (e.g. when testing compression pressure) as a result of gear
engaged or when engine running, or vehicles with automatic transmission as a result of selector lever position
"P" or "N" not engaged (exception: some vehicles do not have a selector lever position "P" ).
Injury hazard
Severe injuries may be caused by unshielded rotating parts in the area of the running engine.
The heat produced by the running engine can result in severe burns if contact is made with individual,
unshielded parts.
Procedural guidelines and safety precautions
As a general rule, carry out work on the running engine only if this is absolutely necessary.
Before starting the engine, apply parking brake .
On models with manual transmission move gearshift lever into Neutral position .
On vehicles with automatic transmission move selector lever into position "P" or "N" (exception:
some vehicles do not have a selector lever position "P" ).
On models which do not have selector lever position "P", secure selector lever to prevent it from
being operated unintentionally .
Wear closed and close-fitting work clothes.
All items of jewelry like chains or rings must be taken off.
Restrain long hair by wearing an appropriate head cover.
Before commencing any work on the running engine, familiarize yourself with the location of potentially
hot parts.
When carrying out work when starting the engine or when engine is running do not touch any hot and
rotating parts .
First aid measures in the event of burns
Do not rub the skin areas affected; flush with plenty of cold water and cover skin with sterile bandages.
Consult a doctor without delay.
RISK OF INJURY CAUSED BY DRILLING GAS-FILLED ASSEMBLIES OR COMPONENTS (NONCOMBUSTIBLE GASES)
- AS00.00-Z-0006-01A
Wear safety glasses and a face mask.
Risk of injury when drilling
There is an increased risk of injury to the skin and eyes when drilling gas-filled assemblies due to shavings
being thrown out. The shavings are picked up by the escaping gases and accelerated to a greater or lesser extent
depending on the pressure. The extent of injuries increases as the pressure increases. The pressures involved

Wear safety shoes (with rubber soles) and use insulating mats.
Ensure a good ground connection is present.
Persons with heart pacemakers should not perform arc welding work.
Remove highly inflammable materials, substances and fluids from the danger zone.
Wear appropriate protective clothing (leather, Kevlar), head covering (welding mask or helmet with
suitable glasses), welding apron and protective gloves.
Perform welding work in well ventilated rooms only.
Wear respiratory mask or use air extractor.
First-aid measures
Rinse affected skin with large quantities of cold water and cover with sterile bandages.
Bring unconscious persons immediately into the fresh air and provide artificial respiration, if necessary.
Consult a doctor without delay.
RISK OF ACCIDENT & RISK OF INJURY - AS00.00-Z-0008-01A
Ensure that jack stands have secure and adequate footing.
An authorized person must occupy the driver's seat.
Wear closed and snug-fitting work clothes.
Do not grasp hot or rotating parts.
Potential risks
Risk of accident
caused by vehicle driving off on its own when under operation (e.g. during tests) with engine running and gear
engaged. Danger caused by vehicle falling off the jack stands .
Risk of injury
Caused by exposed rotating parts next to the running engine and around the drive train which can cause serious
injuries .
The heat produced by the running engine can result in severe burns if contact is made with individual,
unshielded parts.
Safety instructions/precautions
The danger zones around and in the vehicle may only be entered by persons required to conduct the work.
To perform the work, climb into cab.
