Depressurising the hydraulic system
Need to depressurise the hydraulic
system
To enable additional hydraulic functions other
than the basic functions to be used, the truck
has plug connectors (1) on the lift mast.
Clamping and non-clamping attachments can
be connected to these plug connectors.
●
Non-clamping attachments are connected
to the third hydraulic circuit via the plug con-
nectors (1) on the fork carriage and are
controlled via the "5th hydraulic function".
If the truck is equipped with multi-lever op-
eration, the attachments can also be con-
trolled via the "6th hydraulic function".
●
Clamping attachments are not controlled via
the "5th/6th hydraulic function"
Attachments must be installed only by compe-
tent persons. The specifications provided by
the manufacturer and supplier of the attach-
ments must be observed during installation of
the attachments.
Before changing attachments, the hydraulic
system must be depressurised. This is done
using a wizard on the display-operating unit.
If the truck has a "5th hydraulic function" or
"6th hydraulic function", the hydraulic circuits
of these functions must also be depressurised.
