Options for operating in fire hazard areas
Diesel motors represent a potential source of ignition in environments with concentrations of gas,
vapor or dust, and may cause major fires with disastrous consequences for people, the environ‐
ment, and production.
For the operation in fire hazard areas, the machine is equipped with the following accessories:
■ Spark arrestor
4.8.4.1 Option la
Spark arrestor
Sparks in exhaust fumes represent a considerable risk in environments with flammable materials.
Flying sparks combined with flammable materials may cause fires and explosions.
A spark arrestor on the exhaust silencer is required when operating a diesel engine in a fire hazard
area and in forestry and agricultural applications. In such applications, a spark may ignite flamma‐
ble materials.
The spark arrestor prevents the exhaust silencer emitting any glowing fuel residue.
4.8.5 Option ga
Generator option
A generator is installed to provide a power supply to electrical consumers. The generator is driven
from the engine by a drive belt. A tensioning device automatically ensures optimum belt tension.
4.8.5.1 Operating modes
The compressor works with the normal flow rate regulation and generates electrical power at the
same time.
