FAULTS AND REMEDIAL ACTIONS
1. Warning and fault messages
Fig.1
Warning and fault messages are indicated on the multiple display. The warning lamp also flashes and
a warning tone is sounded.
Fault codes are stored and can be called up for more accurate definition of the fault. These codes are
memorised to be called up in the workshop for rapid fault location.
In normal status, display shows the clock (A) and the number of operating hours (B).

Fault messages
FAULTS AND REMEDIAL ACTIONS
Indication accompanied by intermittent audible signal and warning lamp.
Fault codes are stored and can be called up for more accurate definition of the fault. These codes are
memorised to be called up in the workshop for rapid fault location.
In the event of a fault message, proceed as follows:
● Make the system operative by turning ignition off-on (reset).
● If it was a temporary fault, the system is operative again.
If the fault is displayed again:
● Call up fault code and refer to the code table for what measures to take.
Reading out a fault code

Press button, fault code (B) is shown on the multiple display.
Showing more than one fault message at the same time
If the button is pressed repeatedly, the symbols for all existing faults are displayed one after the
other, then symbol (A), code (B), next symbol, next code, and so on. If the button is not pressed
for 3 sec., the symbol for the first fault displayed appears again.
Try activating with alternate key.
Switching on may no longer be possible.

under extreme conditions (e.g. at very low gear oil temperature) even if transmission
is mechanically sound. If the problem persists in normal operating conditions, contact
the workshop immediately.
Hydraulic tank empty.
Valves, front power lift and rear EPC are locked.
Refill hydraulic oil or switch the valve to floating position manually, so that oil can flow
back out of the external cylinder (see also OPERATION Section 17.4).
