Hazards due to noise
The development of noise during operation is influenced by the installa-
tion and operating conditions. Noise with a sound pressure level exceed-
ing 85 dB(A) is harmful.
WARNING
Hazards due to noise
Noise can cause impaired hearing, damage to health, mental disturb-
ances, diminished attention and irritation.
Always wear ear protection when the engine is running.
u
When the sound pressure level is above 85 dB(A), always wear ear
u
protection.
Wear ear protection.
Hazards due to hot surfaces and substances
During operation, turbocharger surfaces and attached parts as well as
operating materials (lubricating oil) become hot. The surface temperat-
ure is dependent on the effectiveness of the insulation being used. The
temperature can become high enough so that it falls into ranges where
burns are possible.
WARNING
Risk of burning
Touching hot surfaces or contact with hot operating materials can lead
to serious burns.
Do not touch hot surfaces and heed the warning plate on the tur-
u
bocharger.
Wear heat-resistant safety gloves and protective clothing.
u
Allow the turbocharger to cool down before carrying out any work.
u
Wear safety gloves to protect against thermal hazards.
