Engine maintenance procedures
Refer to the engine’s operator manual for full
maintenance schedule.
6.2.1
Engine oil level check
Check the engine oil level via the dipstick on the
engine and via the transparent tube on the engine oil
tank.
Add correct oil (see section 6.5), if necessary.
The unit has been equipped with an automatic oil
level control.
The oil level maintainer valve controls the oil level in
the oil sump of the engine. This valve is seated
underneath the oil tank in the back of the unit.
A small oil tank with three level switches is mounted
on the engine and is functioning as a communicating
vessel with the oil sump of the engine. These level
switches (overfill - full - warning - shutdown) are
connected to the CCM and control the oil level
maintainer valve.
When the engine is running, the oil level diminishes.
When the oil reaches the warning level, the CCM
generates an Engine Oil Level warning. This warning
is not immediately displayed on the screen of the User
Interface, but is held back for the duration of the
Engine Oil Level Warning Time.
When the warning is generated, the oil level
maintainer valve is opened. Oil flows from the oil
tank into the oil sump of the engine and into the small
oil tank. The warning condition will disappear.
The oil level rises until the oil reaches the full level.
Then the oil level maintainer valve is closed.
When the warning does not disappear, because the oil
tank is empty, the warning will be displayed on the
screen of the User Interface.
When the oil reaches the shutdown level, the CCM
generates an Engine Oil Level shutdown and the unit
will deactivate.
When the oil level maintainer valve would not close
after the oil level has reached the full level, the oil will
start to overfill the engine.
When the oil reaches the overfill shutdown level, the
CCM generates an Engine Oil Level shutdown and
the unit will deactivate.
