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 techser[email protected]

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.

Maximum working load

WARNING!

The maximum working load (MWL) for the 40.2 ST Radial Winch is 850 Kg (1874 lb)

Subjecting the winch to loads above the maximum working load can cause the winch to fail or

pull off the deck suddenly and unexpectedly during high loads causing severe injury or death.

Installation and Maintenance Manual - Mod.D

Installation

The winch must be installed on a at area of the deck, reinforced if necessary to bear a load equal

to at least twice the maximum working load of the winch.

It is the installer's responsibility to carry out all structural tests needed to ensure that the deck can

bear the load.

Harken®does not supply the screws needed to install the winch since these may vary depending

on the deck on which it is to be installed.

It is the installer's responsibility to choose the correct screws taking account of the loads they will

have to bear.

Harken®assumes no responsibility for incorrect installation of its winches or for an incorrect choice

of mounting screws.

DANGER!

Incorrect installation of the winch may cause severe injury or death. Consult the yard that built

the boat in the case of doubt over the correct positioning of the winch.

WARNING!

Failure to use the correct number and type of mounting fasteners or failure to ensure the

correct deck strength can result in the winch pulling off the deck suddenly and unexpectedly

during high loads causing severe injury or death.

WARNING!

Verify the entry angle of the sheet.This must be 8° with tolerance of

±2°, to avoid sheet overrides and damaging the winch or making the

winch inoperable leading to loss of control of the boat which can lead to

severe injury or death.

WARNING!

Mount the winch on the deck so that the drive gear is positioned where

the sheet enters the winch drum.

Incorrect position of drive gear can weaken winch leading to failure

which can cause an accident leading to severe injury or death.

NOTICE

For winch STA, STC and STCW versions only

you can nd the icon on the skirt to identify the drive

gear position.

Once you have chosen the correct mounting position for the winch on the deck proceed with

installation.

B. Remove the winch and drill the ve 6.2 mm diameter holes.

C. Bolt the base of the winch to the deck using ve M6 bolts (not supplied by Harken®) as

described at Procedure 1 or Procedure 2, correctly chosen for the thickness and type of the

boat deck. Consult the yard that built the boat in case of doubt.

WARNING!

To install the winch on the deck, use only bolts in A4 stainless steel (DIN 267 part11).

Bolts made of other materials may not have sufficient strength or may corrode which can result

in winch pulling off deck suddenly and unexpectedly during high loads causing severe injury or

death.

NOTICE

To mount winches on the deck, do not use countersunk bolts.

D. Fill the mounting holes with a suitable marine sealant.

E. Remove the excess adhesive/sealant from the holes and base drainage channels

F. Reassemble the winch following the steps in Procedure 1 or Procedure 2 in the reverse

order, and apply the products indicated in the section on maintenance.

Installation procedure

Carry out Procedure 1 or Procedure 2, then install the winch on the deck in the chosen

position.

A. Position the base of the winch on the deck and mark the position of the holes or use the

drilling cut-out template at the point where you have decided to place the winch.

Below is a reduced scale diagram.

NOTICE

Before closing the winch, make sure the holes and drainage channels in the base of the winch

are not obstructed.

Positioning the self-tailing arm

Position the self-tailing arm so that the line leaving the winch is led into the cockpit.

Maintenance

Washing

Winches must be washed frequently with fresh water, and in any case after each use.

Do not allow teak cleaning products or other cleaners containing caustic solutions to come into

contact with winches and especially anodised, chrome plated or plastic parts.

Do not use solvents, polishes or abrasive pastes on the logos or stickers on the winches. Do not

use polishes or abrasive pastes on anodised, chromed plated or plastics surfaces.

Make sure that the holes and drainage channels in the base of the winch are not obstructed so

that water does not collect.

Maintenance table

Winches must be visually inspected at the beginning and end of every season of sailing or racing.

In addition they must be completely overhauled, cleaned and lubricated at least every 12 months.

After an inspection, replace worn or damaged components. Do not replace or modify any part of

the winch with a part that is not original.

WARNING!

Periodic maintenance must be carried out regularly. Lack of adequate maintenance shortens

the life of the winch, can cause serious injury and also invalidate the winch warranty.

Installation and maintenance of winches must be carried out exclusively by specialized

personnel.

In the case of doubt contact Harken®Tech Service at techservice@harken.it
