PAWL SPRING MOUNTING
Installing the winch is easy, if you follow these instructions. The numbers in ( ) refer to the
position numbers in the parts list.
Tools required for the installation:
• Allen key (4 mm)
• Allen key (5 mm)
• Ø6.5 mm (1/4”) drill
• Bedding compound
1. Remove screws (1).
2. Remove self-tailing arm (2) and drum (4).
3. Mark location of boltholes using the template.
IMPORTANT: On the 28ST the self-tailing arm (2) is fixed in one position.
Ensure correct positioning of the self-tailing arm, before marking the bolt holes.
Drill bolt holes Ø6.5mm (1/4”). Be sure that no dust comes into contact with the winch
while drilling.
5. Apply a light coat of bedding compound, ensuring that each bolthole is bedded.
Keep drain grooves clear.
6. Fasten base (15) into place using 5 pieces. M6 (1/4”) countersunk head screws.
Use large washers or a backing plate.
7. Assemble in reverse order.
8. Check that the winch is functioning correctly:
- The drum should operate smoothly, by turning the drum clockwise by hand.
- The drum must not turn when trying to turn the drum anti clockwise.
- While turning the winch handle clockwise the drum should turn.
- While turning the winch handle anti clockwise the drum should not turn.
Note the curved
spring “arm”
• 5 x M6 (1/4”) countersunk head screws and corresponding
nuts (length depending on deck thickness)
• 5 x large washers or backing plate
• Ring spanner to match nuts

Tools required for service:
• Allen key (4 mm)
• Screwdriver (small)
1. Remove screws (1).
2. Remove self-tailing arm (2) and drum (4).
3. Insert a winch handle. Pull up the drive shaft (5) gently, while turning gear wheel (10)
and ratchet gear (9) carefully. Remove drive shaft (5).
4. Remove plugs (5.4), pawls (5.3) and arm springs (5.2).
5. Remove ratchet gear (9).
6. Remove shaft ring (6). It can be difficult to get the shaft over the top of the base (15).
By turning and tilting the shaft, it will come off. DO NOT use violence.
7. Remove gear wheel (10).
8. To release the roller bearing (7), gently insert a small screwdriver between roller bearing,
and base (15). Remove roller bearing.
9. The ratchet gear (11) should be cleaned without being removed from the base (15).
10. Clean all parts in benzine. Remember to clean the gear teeth and roller bearing track
inside the drum (4).
11. Assemble in reverse order. During assemble, by the use of a small soft brush lightly grease
all gear teeth, drive shaft, roller bearing, shafts, pawls, springs and bushings. Pawls should
only be lubricated with a very thin film of ANDERSEN WINCH GREASE. It is very important
that pawls can move freely.
IMPORTANT: When assembling the winch, check the functioning of each pawl by pushing
the pawl against the spring. The pawls should move smoothly and automatically return to
their normal position, where the pawls engage with the teeth. If the pawls do not function
correctly, clean and lubricate the pawls and gears. Check the function of the pawls again to
make sure that it works correctly. If the pawls do not work correctly replace the springs and
recheck the functioning.
Malfunctioning pawls may lead to unexpected release of the winch force resulting in fatal
injuries to the user and others.
Service Kit No: 18 (part. no. 710018) contains spare parts for this winch.
Maintenance instructions for PVD coated stainless steel surfaces.
PVD-coated surfaces should be rinsed regularly in fresh water to remove any salt residue, dirt
or other contaminants and dried gently with a soft cloth. To remove grease or other marks,
a mild abrasive free cleaning agent such as spray-on glass cleaning solution may be used.
No caustic detergents or other aggressive or abrasive cleaning agents
should ever be used, as they may damage the surface.
• Winch handle
• ANDERSEN winch grease

28ST FS (V.4.0.F)
Due to the best choice of materials and high precision in manufacturing, we recommend, for
normal use, only to dismantle, clean and lubricate the winch once every second year. Under
extensive use, such as racing, charter or blue water sailing, we recommend to lubricate the
winch once every year.
We strongly recommend always to use ANDERSEN WINCH GREASE, when lubricating your
winch. ANDERSEN WINCH GREASE is a high quality silicone/Teflon grease product.
Most other types of grease, including “marine grease” are not suitable for lubrication of
winches. Non-suitable grease products can cause malfunction, which could result in fatal
injuries for the user and others.
Pawl arm springs should be replaced every second year. Spare arm springs and other parts
that may be required are included in the ANDERSEN Service Kit. Please refer to the service
instruction for the Service Kit suitable for the specific winch.
When the winch handle is not in use but the winch is under load, we recommend, from a
safety point of view, to remove the winch handle from the winch.
To ensure correct function of the self-tailing unit, only use recommended line sizes. When
using the winch with mooring lines DO NOT use the self-tailing function and be sure that the
mooring line is not in contact with the self-tailing arm.
To ensure the best possible functioning of the winch, we recommend that
the winch is placed in accordance with the line entry (shown below).
Be also aware that the self-tailing arm is positioned correctly. We recommend to have the
self-tailing arm positioned within the shaded area (shown above). On this model the self-
tailing arm is fixed, making it very important to establish the proper location of the holes
prior to drilling these in the deck.
To identify the Output Drive Gear, insert a winch handle into the winch
and rotate in both directions, the drive gear will only rotate clockwise
in a fast and slow speed.

DO NOT DISCARD
Failure to observe these precautions
could result in serious injury or death.
Read All Safety Notices and Product Manuals
Do not install or operate this winch before reading and fully understanding the contents of
this Product Manual.
Stay Alert When Operating
Andersen winches are very powerful and have the potential to cause significant damage
and/or serious injury if used improperly or without due caution and vigilance.
Operators Must be Trained
Help prevent significant 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 qualified to operate an electric winch must be kept at a safe
distance from the winch and any rigging or fittings 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 off power before
attempting to resolve the problem.
Avoid Accidental Operation
Remove winch handles and turn off power to the winch when not in use to help avoid
unsupervised or unintentional operation. Failure to do so could result in significant
damage and/or serious injury.
Maintenance
Turn off power to the winch before performing any maintenance or service tasks. Failure
to do so could result in significant 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 off, or leading to a suitable fitting
such as a cleat or bollard.
