Technical data
17.2  Hydraulic connections for implements - supple-
 mentary hoses. 
(!) WARNING (!)
To ensure that the control corresponds to the implement movement, hydraulic 
connections are symmetrically fitted with coupling unions. Never invert such 
positions: movements inversion as well as operating difficulties or unusual 
overload with implement itself could occur.
NOTE
When using coupling unions it is necessary to verify that there is no trace of 
soil, curt etc. on the unions and inside the seats so as to avoid the oil contami-
nation and consequently wear the tightening “ surface
”
 of unions or ram seals.
17.3  Oil cooler (heat exchanger)
The crane is equipped with an oil cooler (air-oil heat exchanger) to prevent 
damage caused by an excessive increase of the oil temperature. 
NOTE
When working in a low temperature climate, we recommend to bring the 
hydraulic oil up to working temperature prior to starting work, This is 
best done by operating the crane thru all its functions ram stroke end.
(!) WARNING (!)
The heat exchanger openings must be kept clear and clean. At no time should 
it be covered.
