Crane operation
Fig. 111 Controls, crane operation,
seat facing forward
The control system which controls the crane is
automatically switched on when you turn the operator’s
seat backwards, in this position you can use all crane
functions.
For safety reasons the crane control levers do not affect
the crane when the operator’s seat is turned towards the
cab door.
When the seat is facing straight forward, you can usually
only lower the crane’s lifting arm for safety reasons; other
crane functions are not available in this situation.
With the “”Crane driving seat facing forward” button (button
13 on the right armrest panel) it is possible to over-ride the
control system and obtain full crane function even with the
seat facing straight ahead; the crane function is cancelled
as soon as the seat is turned.
The crane hydraulic system operates more smoothly if you
use operating revs of 1,200-1,500 rpm, see 4.6
6.17.2
If the crane does not work
Check that:
• the machine starts, otherwise see 6.3.1
• there are no active error codes.
• the chair is turned backwards and the sensor for this is
not working.
• there is hydraulic oil in the hydraulic system.
• there are no broken hoses.
Contact a service dealer if none of the above solves the
issue.
6.17.3
Loading / unloading
Loading of timber and pulpwood in various lengths should
be carried out with the hydraulic gate in Timber-position
(folded down). Loading of pulpwood in 3-metre lengths
should be carried out with the hydraulic gate in Pulpwood-
position (folded up). This way you will get the best possible
longitudinal stability.
