1 Safety / 1.12 Hazards during operation and maintenance
WARNING
Hot surfaces on the non-insulated turbocharger
Non-insulated turbochargers can cause serious injuries to personnel (burns).
The turbocharger is supplied with or without insulation in accordance with
the purchase order received from the enginebuilder. If supply is without in-
sulation, the enginebuilder is responsible for providing the turbocharger
with proper insulation and for providing protection against contact with hot
surfaces.
Compliance with the instructions and specifications given by the en-
u
ginebuilder to protect against hot turbocharger surfaces is compulsory.
Wear safety gloves to protect against thermal hazards.
Hazards due to rotating parts
WARNING
Physical hazards
Contact with rotating parts can cause severe injury. The turbocharger must
never be used without the filter silencer or the air suction branch. With the
engine stopped, the rotor can rotate due to the stack draught alone.
Operate the turbocharger in compliance with the specifications.
u
Secure the rotor against unintentional rotation during maintenance.
u
Wear safety gloves to protect against mechanical hazards.
Hazards due to electrical installations (if present)
WARNING
Dangers during work on electrical installations
Electrical installations use voltages that can lead to severe injury to person-
nel or accidents resulting in fatalities.
At the same time, electrical or electronic components and parts can also be
damaged or destroyed.
Only specially trained personnel should perform work on, or with, elec-
u
trical components.
Observe national regulations.
