Radial Winch
70.3 ST EL/HY
Installation and Maintenance Manual - Mod.F
Installation
The winch must be installed on a flat 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.
After correctly positioning the final drive gear with respect to the load, check that the motor,
gearing, electrical wiring and/or hydraulic pipes can be housed below decks. To help find the
optimal compromise, remember that, to make the installation of the motor easier, it can be coupled
to the winch in different positions.
Once you have decided the correct mounting position for the winch on the deck and checked the
space available below deck, proceed with the installation.
