Maximum working load
WARNING!
The maximum working load (MWL) for the 70.2 ST Performa™ Winch is 2700Kg (5952 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
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.

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

Installation procedure
Carry out the Procedure, 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.

B. Remove the winch and drill the six 8.5 mm diameter holes.
C. Bolt the base of the winch to the deck using ve M8 bolts (not supplied by Harken®), 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

Maintenance
F. Reassemble the winch following the steps of the Procedure in the reverse order, and apply the
products indicated in the section on maintenance.
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, on the stickers on the winches or on
any anodized, chrome plated and plastic 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.

(
Inspect balls inside the drum and carefully check the correct position; if it is necessary to put back
any balls, push balls in the race (as shown below):
Once the winch is completely disassembled, clean the parts: use a basin of diesel oil to soak
metal components and rinse plastic parts in fresh water. Once you have done this, dry the parts
with cloths that do not leave residue.
II. Remove the jaws n°22
Inspect gears, bearings, pins and pawls for any signs of wear or corrosion.
Carefully check the teeth of gears and ring gears to make sure there are no traces of wear.
Check the roller bearings and check there are no breaks in the bearing cages.
Replace worn or damaged components.
Carry out maintenance on components using the products listed below.
For more information on which products to use where, refer to the exploded diagram below.
Use a brush to lightly lubricate all gears, gear pins, teeth and all moving parts with grease.
