1.3 General warning & instructions
1.4 Product information
Make sure the winch is dimensioned according to Seldén’s design standards and not subjected to loads greater
than those stated in the brochure and instruction materials and is used solely for its intended use, i.e. normal
sailboat applications for running rigging.
Exceeding the stated maximum working load (MWL) may lead to winch failure or that the winch detaches from
the boat which may lead to serious injuries.
Keep hands, ngers, hair and clothing away from moving parts. It is recommended to let only one person, work
with the winch at any one time.
If a Seldén winch, despite the above, is used for going aloft in the mast, double halyards must be used, to be
hauled in and eased off at the same time. (Seldén rigging manual “Hints & Advice”, 595-540-E, “Working
aloft”).
For your own personal safety, make sure the winch is installed, regularly inspected and maintained according to
this manual.
This manual is available in English only. If you do not understand the manual content we advise you to obtain
expert assistance for the installation and operation!
Seldén have two ranges of winch, S-winches and the R-winches, which are manually operated and of selftailing type with two forward gears.
The difference between these two models are that the R-winches are revisable, which means it is possible to let
the line out by reversing the winch drum using the winch handle. The S-winches do not have this feature.
With modern manufacturing technology and by optimizing the choice of materials Seldén have succeeded to
reduce the weight and the need of maintenance to a minimum.
The drum has a unique design consist of several concave surfaces which provide an extraordinary grip for the
line. It means fewer turns on the drum which reduces the risk of an override and allows the line to be released
quickly.
The self-tailing jaws has a design which makes it possible to pull the slack out of the sheet with the line sitting
in the self-tailer and with the winch handle mounted. This means safer and quicker operation.
The Seldén winch is designed for line handling on sailboats only!
Exceeding maximum working load may lead to winch failure or serious injuries.
1.4.1 Seldén winch range
1.4.2 S-winch features
Page 5

Seldén have two different models of winch handles designed for S-winches and R winches respectively. The
winch handle for the R-winches differs from the S-winch handle by it having a button for a reverse function on
the grip. Both winch handles t in each winch model and works for forward winching, while the reverse
function on R-winch only can be operated by the R-winch handle.
The S-winch has two different fastening methods:
1. By hexagon headed bolts which slide into a groove in the winch base and where the hexagon heads are
locked against rotation due to the winch base structure. This method allows installation without dismantling
the winch. The bolts are tted through deck and fastened using washers and nuts. (See g.3.2.1.c).
2. By hexagon socket head cap screws (Allen screws) mounted from above. The winch needs to be dismantled. E.g. for cases where the boat is prepared with metal inserts in the deck construction. (See g. 3.2.3.j).
See chapter “Installation” for requested screw type and dimension.

2 Operation instructions
2.1 Winch handle
2.2 Winching
Seldén S-winches are manually operated and are a self-tailing type with two forward gears.
The purpose of the winch handle is to operate the winch. The S-winch handle (Art. No. 533-927-20) has no
reverse button and does not work with the reversible R-series. R-winch handle (Art. No. 533-927-10) with
release button does work with the S-winch series. See g. 1.4.a and 1.4.b.
Fast gear: Turn the winch handle clockwise.
Low gear: Turn the winch handle anticlockwise.
2. Lead the line over the self-tailing arm, into the self-tailing jaws for ¾ of a lap. The line remains in the selftailing jaws all the time during the winching operation.
3. Put the winch handle into the socket.
1. With the line, take 2-3 turns clockwise around the winch. The number of turns determines the grip and is
related to the line construction.
Fig. 2.a
Consider the risk of injury which is associated with winching! See chapter 1.3.
Due to the design of the self-tailing jaws it is also possible to pull the slack out of the sheet with the line sitting
in the self-tailing jaws and with the winch handle mounted. This means safer and quicker operation.

3 Installation
3.1 Installation preparations
1. The winch should be mounted on a at surface. If not, any uneven surface must be compensated with shims.
2. Make sure the installation area is strong enough for the chosen size of winch.
3. The winch should not be mounted on any part of deck that is laminated using sandwich construction, such
as foam, etc.
4. If the winch is to be mounted on a surface of steel, bronze or brass, the base must be insulated against
galvanic corrosion. This is best done using a plastic insulator (0.5-1 mm) or sealant which covers the entire
contact area between the base and the mounting surface.
Decide the orientation of the winch according to operation direction, with reference to the mostly used line and
the bulb on the winch base. See g. 3.1.1.a or the drilling template, enclosed in the winch package.
The line should enter the winch according to g. 3.1.2.a to prevent from override.

in the winch base and where the hexagon heads
are locked against rotation due to the winch base
structure. No need to dismantle the winch. To
be used with washers and nuts below deck.See
chapter 3.2.1.
2. Hexagon socket head cap screw (Allen screws),
mounted from above. The winch needs to be
partly dismantled. E.g for cases where boats are
prepared with metal inserts in the deck construction. See chapter 3.2.2.
1. Cut the enclosed drill template to match the winches outline.
2. Place the template on deck at the desired position according to chapter 3.1.1 ”Winching orientation”

3.2.3 Installation with Hexagon socket head cap screw (Allen screws) with
cylindric head (None sliding bolt installation)
If the winch should be tted with Hexagon socket head cap screw (Allen screws), the winch must be partly
disassembled. This method of installation has to be used for threading into the deck, e.g. if the boat has purpose
made metal plates laminated into the deck structure or if non-hexagon headed through deck screws are used
with washer and nuts.
Tools needed for winch dismantling:
S30 & S40: Hexagon key 5 (M6), Hexagon key 6 (M8)
S48 & S54: Hexagon key 6 (M8), Hexagon key 8 (M10)

6. Mark the fastening holes using the winch base as a template or use the enclosed paper drilling template.
If the winch base is used as a template, use a smaller drill bit to mark the location of the hole.
If the paper drilling template is used, pre-drilling with a smaller drill (Ø 3-4 mm) is recommended for better
accuracy.
7. Drill either for through deck fastening or for threading in metal inserts.
8. Make a countersunk recess at the top of the holes. Along with the sealant, this recess will create aid sealing
around the bolt.
10. Reassemble the winch in reverse order of dismantling. Mount the self tailing arm so it guides the line into
the cockpit or preferred direction.
9.
Through deck fastening:
Slide an L-shaped washer onto each screw according to
