Commissioning and operation

System monitoring
Caution:
In the event of faults have their cause immediately ascertained and rectified so that
no major damage will occur.
During operation the oil pressure of the engine lubrication and the coolant temperature
are to be monitored.
If the monitoring devices indicate a drop in lube oil pressure or coolant excess tempera-
ture, the engine is to be switched off immediately.
Prolonged idling while engine is cold is to be avoided, because this, as is well known, ex-
poses all internal combustion engines to increased wear through corrosion. Letting the
engine idle over prolonged periods is detrimental to the environment.
Switching off
After operation at full load let engine idle for about 5 minutes.
D
Solenoid valve for gas supply closes.
D
Engine runs down.
D
After about 5 seconds the ignition system and the electronic speed control are
switched off.
Danger:
Chronologically speaking, the gas supply is always to be switched off before
the ignition system, so that no unburned residual amounts of gas can get into
the exhaust-gas pipe.
In the event of damage to the solenoid valve, never switch off via the igni-
tion system.
D
Shut main shut-off cock.
D
Switch off ignition system only after engine has stopped.
