Hazards during operation and maintenance

Noise hazards
The turbocharger's noise emission is influenced by its installation and operating conditions.
A noise level exceeding 85 dB(A) is harmful.
WARNING
Noise hazards
Exposure to noise can harm the hearing system, impair health and the psy-
chological state and may lead to lack of attention and irritation.
When the engine is running, always wear ear protection.
u
Always wear ear protection if the sound pressure level exceeds 85 dB(A).
u
Wear ear protection.
Hazards due to hot surfaces
Surfaces of the turbocharger, attached parts and operating fluids (lubricating oil) get hot
during operation. The surface temperature depends on the efficacy of the existing insula-
tion. The temperature may rise to a level that can cause burns.
WARNING
Danger of burns
Touching hot surfaces or contact with hot operating fluids can cause burns.
Do not touch hot surfaces. Observe the warning plate on the turbochar-
u
ger.
Wear heat-resistant safety gloves and protective clothing.
u
Wait for the turbocharger to cool down before carrying out any work.
u
Wear safety gloves to protect against thermal hazards.
