maintenance.
Regular inspection of the installation is
recommended in the following areas
where applicable.
1. Check that Hydraulic Steering systems
are free from leaks and trapped air.

has been designed
to achieve very high standards of reliability
combined with ease of servicing.
If a fault should appear, please double
check that all connections in the
connector unit are sound and that the
heavy power cable connections are tight
and free from corrosion. If you are
satisfied that all connections are sound,
the simple check procedure tabulated

likely fault area.
Since the course computer houses the
majority of the electronic control system
there is a high probability that if an
electronic fault has
it will be
located in this area. The course computer
unplugs easily for servicing (Section
2.1.1).
Control units are removed using a
suitable lever to separate the pads starting
at one corner. Do not use excessive force.
Disconnect from the connector unit and
withdraw the interconnecting cable

The faulty unit should be removed and
returned to your nearest service agent.
