ANDERSEN Stainless Steel Winches®
Your Andersen winch is made with the care and craftsmanship that
come from more than sixty years of experience. Andersen winches
are built to last, to retain their exceptional nish and to deliver
season after season of reliable performance and sailing pleasure to
their owners through the years.
Compact Motor™ functionality
The Andersen Compact Motor™ is a brushless DC motor, carefully
matched to a low prole planetary gearbox, which requires less
space for installation and draws considerably less current than
traditional motor/gearbox congurations. Simplied electrical
installation requires no external control box.
The Compact Motor™ includes a dedicated circuit breaker with
integral controller and the illuminated “intelligent” push button
which regulates speed and power in proportion to the pressure
applied.
Manual operation is possible at any time using a normal winch
handle.
Monitoring and protection
The integrated controller will cause the motor to stop without
tripping the circuit breaker if one of the following conditions is
detected:
• Maximum pulling load exceeded. The motor will cut out if
the pre-set maximum pulling load of the winch for electrical
operation is exceeded. Operation can resume within a few
seconds when the load returns below the limit.
• Overheating. The motor will cut out if the temperature of the
motor circuit reaches 60˚C (140˚F). Operation can resume when
the temperature returns to normal.
• Maximum continuous run time exceeded. The motor will cut
out after running continuously for 4 minutes and 15 seconds.
Operation can resume after releasing the push button to pause
operation for at least 30 seconds.
In these cases, the illuminated push button will ash, indicating that
the controller will reset automatically when operating conditions
return to normal.

Stay Alert When Operating
Andersen winches are very powerful and have the potential to cause signicant damage and/or serious injury if used
improperly or without due caution and vigilance.
Operators Must be Trained
Help prevent signicant damage and/or serious injury by ensuring any person operating a winch has a thorough
understanding of its proper operation and is aware of the potential hazards involved. As a minimum, all winch operators
must read and understand this Safety Notice Sheet and the Product Manual.
Particular attention is drawn to the following points:
• Children and others not qualied to operate an electric winch must be kept at a safe distance from the winch and any
rigging or ttings that are under load.
• Long hair and/or loose clothing must be tied back to avoid being caught in the winch.
• In the event of a rope override or other fault, stop the winch and turn o power before attempting to resolve the
problem.
Avoid Accidental Operation
Always turn o power to the winch at the circuit breaker and remove winch handles when not in use to help avoid
unsupervised or unintentional operation. Failure to do so could result in signicant damage and/or serious injury.
Maintenance
Turn o power to the winch before performing any maintenance or service tasks. Failure to do so could result in signicant
damage and/or serious injury.
Lifting Operations
The winch must not be operated with the rope in the self tailer when used in any kind of lifting operation. Any lifting
operations should be conducted by two persons in order to maintain constant visual contact with the object being lifted.
Furthermore the self tailer must not be used as a cleat for a rope used to lift or suspend any object. The rope must be
secured properly by tying o, or leading to a suitable tting such as a cleat or bollard.
Failure to observe these precautions could result in serious injury
or death.

PRODUCT MANUAL
28/34/40ST Below Deck Compact Motor™
Installation Instructions
STEP 1
Determine the position of the winch and motor unit
1.1 Magnetic elds in the motor may aect compasses even
when the motor is not in use. Install the motor at least
1m (3ft) away from any compass, and always have your
compass recalibrated after installation.
1.2 The winch should be positioned with the recommended
line entry angle of 3-8° from horizontal.
1.3 Refer to the Winch Data Sheet for your winch model for
clearance/space requirements for the motor unit below deck.
You may choose to drill a small pilot hole to indicate the
position of the centre of the drive shaft, to assist with this.
1.4 Note the location of the drain port in the base of the motor.
If the mounting surface is not horizontal due to deck camber
or other factors, plan the installation such that the drain port
is situated at the lowest point in relation to the slope of the
mounting surface. The drain tube [A14] will be attached to
this port to allow any moisture from condensation to escape
and drain to the bilge.
Recommended line entry angle
3-8 degrees

STEP 2
Install the deck plate
2.1 A stainless steel deck plate [5] is included with the Compact
Motor™ unit. The drilling template [A3] can be used to identify
the locations on deck for the mounting holes and deck cut-outs.
2.2 The 28ST and 34ST winches have a xed self-tailing arm, so it is
important to position the deck plate in the correct orientation to
obtain the desired arm position. The self-tailing arm of the 40ST
winch can be adjusted after installation into one of eight dierent
positions, as indicated on the drilling template.
2.3 The self-tailing arm should be positioned to allow the rope to
drop clear of the winch as it feeds out of the self-tailer. Positions
will typically be as indicated by the shaded sectors in the diagram.
2.4 After conrming the mounting location and orientation of the
winch, clean the mounting surface and place the template in the
required position on the deck. Ensure that the surface is at and
there is adequate space and clearance on deck for the winch
base and below deck for the motor.
2.5 With the drilling template in the desired orientation, cut the
Ø86mm (3 3/8’’) hole for the motor drive shaft housing.
2.6 Drill the Ø6.5mm holes for the M6 deck plate mounting bolts
(or Ø9/32” holes for 1/4” bolts).
2.7 Clean any wood or breglass splinters from the holes, and clean
the deck thoroughly to ensure deck sealant can adhere properly.
2.8 Apply sealant to the deck where the deck plate will be xed. For
aluminium boats use a galvanic isolating ring/gasket.
2.9 Fit the deck plate to the deck using appropriate length M6 or
1/4” countersunk head bolts, large washers or backing plate, and
locking nuts.

STEP 3
Fit the motor unit to the deck plate
Correct alignment of the motor during assembly is essential. Improper
alignment can cause excessive noise and vibration and lead to
premature wear of bearings and gears. For best results the following
steps should be carried out by two persons.
3.1 Back out the locking grub screw [2] and use the pin spanner [A8]
to remove the clamping ring [3] from the top of the drive shaft
housing, taking care that the O-ring underneath remains in place.
3.2 Screw the M6 eye bolt [A7] into the threaded hole in the top of
the drive shaft. Attach a strong rope or use a lifting device to raise
the motor unit into position under deck so that the drive shaft
protrudes through the large octagonal hole in the deck plate.
3.3 Align the motor unit so that the protruding octagonal detail
at the top of the drive shaft housing mates snugly with the
octagonal recess in the deck plate, for a uniform ush t.
3.4 Fit and securely tighten the clamping ring using the pin spanner,
then insert and tighten the locking grub screw. Watertight
assembly is ensured by the O-ring under the deck plate; no
additional sealant is required.
3.5 Refer to the diagrams below to check for correct clearance
and alignment.

STEP 4
Fit drain tube.
4.1 Remove the plastic plug from the drain port tting and push
the drain tube [A14] into the tting until it stops. Lead the drain
tube below deck to a low point in the boat where it can drain to
the bilge, then cut o any excess length. At most there should
only ever be a drop or two of water from condensation that will
pass through the tube.
STEP 5
Install push button
The push button requires 50mm (2”) clearance depth below the
mounting surface. It is supplied with a short 190mm (7 1/2”) long
cable lead; this is connected below deck to the 1000mm (39”) long
control cable [A12] and then to the short cable leads from the motor.
Extension cables are available and may be ordered separately if
necessary.
5.1 Select the desired location. For safety reasons it is
recommended that the push button [A1] is located in close
proximity to the winch, preferably within reach.
5.2 Determine the preferred orientation of the hinged cover (on
vertical surfaces it should open upwards). Then using the
drilling template or the rubber gasket [A2] as a guide, drill a
Ø25mm (1”) hole.
5.3 Drill a Ø3mm (1/8”) hole in each of the three mounting screw
locations.
5.4 Fit gasket and push button in place. Secure the push button unit
with the 3x M4x20mm self tapping screws [A10], using a small
amount of sealant at each hole.
5.5 Ensure that the breather channel on the side of the through-deck
tube of the push button is clear and free of dirt or sealant.
