Hydraulic pump
Control elements placement
Outer hydraulic circuit
It delivers pressure oil for hydraulic appliances connected to the hydraulic outlets terminated by quick
couplings. Both the rear and front drawer sockets are 12.5 mm in headroom and are international ISO
standard 5675 compliant.
Connecting and disconnecting quick-couplers
When connecting and disconnecting the quick-couplers pay increased attention with regard to
the residual oil that remains in the socket or on the plug of the quick-coupler. For environmental
reasons after every disconnection of quick-couplers this residual oil must be removed with any
textile material.
Quick-couplings with drip collection
The hydraulic pump cannot be disengaged. When the
engine is running, the pump is in operation.
The pressure generated in the hydraulic system by the
hydraulic pump is limited by a relief valve to 20 MPa.
