Mercedes-Benz ML320. Service manual - part 558

 

 

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.  

Possible hazards

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

may be 75 bar or more. 

Safety instructions/precautions  

Wear safety glasses and a face mask.  

First aid measures  

Do not rub any skin areas affected, as there is the risk that the shavings will break off leaving some of 
them behind.  

If necessary, consult a physician.  

THE HIGH VOLTAGE USED FOR ARC WELDING PRESENTS A LETHAL HAZARD - AS00.00-Z-0007-01A 

Use insulating mats. Wear protective clothing, safety glasses, and protective mask. Remove highly 
inflammable materials from the danger zone. Use air extractor.
  

Possible hazards  

Lethal hazard from high voltage used for arc welding.  

If arc welding work is performed in moist surroundings or on a wet surface, electricity conducted through the 
human body may pose a lethal hazard . This can result in severe burns, heart fibrillation or cardiac arrest. 

 Persons with heart pacemakers should not perform arc welding work.  

Risk of explosion!  

Welding in the area of highly inflammable substances can cause explosions. 

Risk of injury from welding spatter and UV light when welding as well as from flying sparks when 
grinding
  

Severe burns can be caused if hot chips (flying sparks) from grinding or welding sparks or spatter from liquid 
welding material come into contact with unprotected body parts. 

Normal work clothing (consisting of cotton or synthetic fiber) can ignite from welding sparks and spatter from 
liquid welding material or from flying sparks when grinding and cause severe burns. 

The UV light emitted during arc welding can lead to eye damage and burns on unprotected skin. 

Risk of poisoning from inhaling welding gases  

Inhaling the vapors resulting from combustion while welding can lead to headache, nausea, dizziness and 
unconsciousness. 

Procedural guidelines and safety precautions

me 

 

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.
