Danger Of Burning - Bosch ETZ 309 Bedienungsanleitung

Instructions for your personal safety and for the
protection of equipment/vehicle components
Danger of injury
Danger
of crushing
If the vehicle is not prevented from rolling
away, there is a danger of people being crus-
hed against a workbench, for example. Both
running and stationary engines have rotating
and moving parts (e.g. belt drives) which may
cause injuries to fingers and arms. A special
hazard is presented by electrically driven fans,
in that they may be switched on without
warning while the engine is stationary and the
ignition is switched off.
There is a danger of tripping over the protru-
ding rollers, the connecting cables and the
power cable of the test system.
Do not place heavy objects on or lean on the
sensor holder, because there is a danger of it
breaking and falling on your feet.
Safety precautions:
- Take steps to prevent the vehicle from
rolling away while it is being tested.
Select the park position if the vehicle has an
automatic transmission and apply the hand-
brake or lock the wheels with chocks (wed-
ges).
- Keep well away from rotating/moving parts
while the engine is running.
- When working on or in the vicinity of electri-
cally driven fans, allow the engine to cool
down first, then disconnect the plug of the
fan motor.
- Keep the tester connecting cables well
away from all rotating parts.
- Lay the connecting cables in such a way
that no-one can trip over them.

Danger of burning

When working on a hot engine, there is a risk
of injury from burning if such components as
the exhaust gas manifold, the turbocharger,
the Lambda sensor, etc. are touched or if
parts of the body come too close to them.
These components may be heated to tempe-
ratures of several hundred degrees Celsius.
Depending on the duration of the exhaust gas
measurements, the sampling probe of the
exhaust gas measuring instrument may also
become extremely hot.
Safety precautions:
- Always wear protective clothing, e.g. gloves.
- Allow the engine to cool down first (this also
applies to auxiliary heating systems).
- Keep the tester connecting cables well
away from all hot parts.
- Do not leave the engine running any longer
than necessary for the test or setting.
Noise
Noise levels in excess of 70 dB(A) can occur
when measurements are carried out on a
vehicle, especially at high engine speeds.
Damage to hearing may result if human beings
are exposed to noise at such levels over an
extended period of time.
Safety precautions:
- If necessary, noise protection facilities must
be provided by the owner at all workplaces
in the vicinity of the testing area.
- If necessary, suitable personal noise protec-
tion facilities must be used by the operator.
