NOTE!
Make sure the skirt is properly hooked onto the Wince base.
Proceed to install the Winch according to the following procedure:
1. Install the Winch on a flat surface in the chosen position.
2. Place the Winch base in the area selected and mark the holes or use the drilling template (figure
16.1 ). The drilling template is available on the Harken
®
website, www.harken.com . Download, print
and compare the template to the Winch to check that the template size and the position/size of the
holes are correct. See small template on the following page.
3. Remove the Winch and drill the five (5) 6.2 mm diameter holes. For drilling and tapping refer to
the sector standards for the size of the drill/tap. Important: do not flare the holes. Besides, make
a hole of min. 78 mm at the centre
4. Screw the Winch base onto the support plate. Use screws of the correct length for the thickness
and the type of support surface. In the event of any doubts, contact the manufacturer. Use five (5)
M6 hex head (HH) screws, washers and nuts.
5. To ensure the correct Maximum Working Load (MWL) all the five screws, nuts and washers must
be correctly tightened (Torque 10 Nm).
NOTE!
When downloading the Winch drilling template make sure that you use the correct paper size and
that the printer prints at 100%. Before drilling, check that the template is correct in every detail.
Harken is not liable for incorrect drilling caused by a defective template
NOTE!
1/4" hex-head screws are not suitable for holes and cannot be used to install the Winch.
WARNING!
The use of an incorrect number or length of the fixing elements and/or the incorrect tightening may
result in a sudden and unexpected failure of the Winch in the event of high loads, with consequent
serious injury or death.
