Oil pressure
Max. oil pressure:
warm engine at speed above 800 rpm 6 bar
Normal oil pressure:
warm engine at operating speed 3 - 6 bar
Min. oil pressure:
warm engine at 800 rpm 0.7 bar
At speeds below 800 rpm, the gauge may show low oil pressure without there
being a fault.
Oil pressure below 0.7 bar at speeds above 800 rpm will cause engine dam-
age. The engine must be stopped immediately.
Charge test lamp
If the lamp lights during operation:
- Check/adjust the alternator drive belts as described under maintenance
point See page 33.
- If the charge test lamp is still lit, there may be a fault in the alternator or
in the electrical system.
STOPPING THE ENGINE
1. Allow the engine to run without load for a few minutes if it has been run
with a high continuous load.
2. Stop the engine using the stop control. Engines with a stop solenoid are
stopped using the stop button. Hold the stop button depressed until the
engine has fully stopped.
3. Engines with battery master switch: Cut the power using the battery
master switch. (Does not apply to emergency power back-up units).
4. Set the control switch to 0. (Does not apply to emergency power back-
up units).
Emergency stop
The stop solenoid linkage system has a knob marked ”STOP”. Pull the link-
age system to the stop position using this knob if it is not possible to stop the
engine using the stop solenoid.
Danger of turbo damage or
boiling over if the engine is
stopped without cooling off.
The power must not be cut
until the engine has stopped.
High lubrication oil pressure
(above 6 bar) is normal when
starting a cold engine.
