Introduction
This manual gives technical information on winch installation and maintenance, including
disassembling and reassembling.
This information is DESTINED EXCLUSIVELY for specialised personnel or expert users.
Installation, disassembling and reassembling of the winch by personnel who are not experts may
cause serious damage to users and those in the vicinity of the winch.

*** at 135 bar a 20 L/min
NOTE
The ratio the line load - pressure are evaluated at flow 20 l/min,
at different flow the line load - pressure ratio change and it's minimum at motor stall.
The pressure on the graph it's the pressure drop between in and out motor ports.
The perfermance are evaluated measuring the pressure and flow on the motor ports.
Performance data based on oli with a viscosity of 35mm^2/s [165 SUS] and temperature of 50° [120° F]
