TROUBLE SHOOTING
Error messages
There are two types of error messages that can appear
on the display:
Service messages - These messages do not
represent any direct danger for the operator or the
machine.
Warnings - These warn of faults or safety defects
that can cause mechanical damage.
All error messages that have been acknowledged re-
main as small yellow red warning triangles in the eld
for service and can be accessed by bringing up the
service menu and selecting ’Warnings”. The messages
are listed in order of priority, highest priority rst.
When a fault that has in some way restricted the ma-
chine’s functions ceases, a message appears on the
display. This message must be acknowledged for the
machine to return to full functionality.
Service messages
When a service message appears on the display, the
operator is made aware of it through the work light
ashing three times.
The service message remains on the display until the
operator has acknowledged it. The message disap-
pears from the display and is replaced by a yellow
warning triangle in the eld for service. The triangle
symbol remains for as long as the message is current.

selecting override. The light stops ashing and the mes-
sage disappears from the display and is replaced by a
