Installation and Maintenance Manual - Mod.D
Introduction - Technical characteristics
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.
Harken®accepts no responsibility for defective installation or reassembly of its winches.
In case of doubt the Harken®Tech Service is at your disposal at techservice@harken.it
This Manual is available only in English. If you do not fully understand the English language, do
not carry out the operations described in this Manual.

NOTE
The ratio the line load - pressure are evaluated at ow 20 l/min,
at different ow 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 ow on the motor ports.
Performance data based on oli with a viscosity of 35mm^2/s [165 SUS] and temperature of 50° [120° F]
