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.
u
When the engine is running, always wear ear protection.
u
Always wear ear protection if the sound pressure level exceeds 85 dB(A).
Wear ear protection.
Hazards due to hot surfaces
Surfaces of the low-pressure and high-pressure stage, attached parts and operating fluids
(lubricating oil) get hot during operation. The surface temperature depends on the efficacy
of the existing insulation. 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 severe
burns.
u
Do not touch hot surfaces. Observe the warning plate on the low-pres-
sure and high-pressure stage.
u
Wear heat-resistant safety gloves and protective clothing.
u
Wait for the low-pressure and high-pressure stage to cool down before
carrying out any work.
Wear safety gloves to protect against thermal hazards.
