3.15.1 HOW TO REMOVE THE MACHINE
DANGER
q
When removing the machine, use a wire rope suitable
for the weight of the machine to be removed.
If the machine gets stuck in mud and cannot get out using only
its motive power, or in case of breakdown, use a wire rope as
shown in the figure on the right.
IMPORTANT
q
In case of failure of the hydraulic circuit, before recover-
ing the machine release the negative brake installed on
the rear axle ( "4.8.1.d RELEASING THE PARKING
BRAKE").
3.15.2 IF THE FUEL HAS BEEN COM-
PLETELY DEPLETED
Before starting the engine when the fuel has been completely
depleted and therefore air has entered the fuel supply circuit, it
is necessary to bleed the fuel supply circuit.
For the necessary operations, see "4.8.8 MAINTENANCE
EVERY 500 HOURS OF OPERATION".
