FAULTS AND TROUBLESHOOTING
DANGER
Any repair work, maintenance or troubleshooting
must be carried out with machine stopped, boom
in rest position or laid on the ground, parking brake
engaged and ignition key removed.
This chapter represents a practical guide for the
operator for fixing the most common failures and, at
the same time, detecting those interventions that must
be carried out by qualified technical engineers.
If you are unsure about anything, do not carry out
operations on the machine, but call in a skilled
technician.
