Generality
Many years experience of our product has allowed us to identify and classify the most
common faults which occur. In most cases it requires accurate hydraulic and electric
troubleshooting and simple rectification. In the following table we report the most fre-
quent inconveniences and our suggested remedies.
(!) Checking and adjustment of oil pressures of valve settings must be carried out
by an authorized service agent, under penalty of warranty forfeiture.
(!) ATTENTION (!)
In the event that the crane ceases to operate and the code "alarm" with a number appears
on the Display B. Call your FASSI authorised service centre reporting the Alarm number
with the crane model and serial numbers. If the fault cannot be cleared follow the procedure
in the chapter "Controls to operate the crane" and overide the dump valve EVI.
THIS IS ONLY A TEMPORARY ACTION FOR EMERGENCIES, the crane should be
taken to a FASSI service centre for repair as soon as possible.
