NOTICE:
the quick coupler extends the length of the arm. Make sure to check the operating range of the coupled
attachment in order to avoid risk of striking the cab or the machine frame.
NOTICE:
never operate with a quick-coupled hydraulic breaker for an extended period of time, in order to reduce the
risk of premature wear, failures or breakage of the quick coupler. Never use the breaker as a lever, as this subjects
the quick coupler cylinder to stress.
NOTICE:
be sure to read and understand the Operator's Manual of the quick coupler to proper installation, usage and
maintenance.
Quick coupling hydraulic circuit and connections
The machine can provide a quick coupling hydraulic cir-
cuit. The two rigid pipes located both on the top of the arm
allow to install properly and safely the hoses to connect
the hydraulic attachment to the quick coupling hydraulic
circuit.
