DANGER
Risk of death
There is a risk of serious injury, including death, due to explosion in the crankcase as a
result of incorrect installation.
In the event of an oil mist alarm, do not approach the engine again until the
alarm threshold has dropped to at least < 50% relative oil mist concentration.
The manufacturer recommends that only approach the engine again when the
alarm threshold has dropped to 0% relative oil mist concentration.
If a Remote Indicator II is used for remote monitoring, it must be used to
continuously check the current oil mist concentration.
Familiarise yourself with the basic safety instructions before starting to operate
the device.

instructions must be observed.
