GENERAL INFORMATION
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 selftailing unit, only use recommended line sizes. When using the winch with
mooring lines DO NOT use the selftailing function and be sure that the mooring line is not in contact with the
selftailing 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 selftailing arm is positioned correctly. We recommend to have the selftailing arm positioned
within the shaded area. On 12ST, 18ST and 28ST the position of the selftailing arm is fixed, making it very
important to establish the proper location of the holes prior to drilling these in the deck. On all other models,
the selftailing arm can be placed in several different positions after having installed the winch.

INSTALLATION
Installing the winch is easy, if you follow these instructions. The numbers in ( ) refer to the position numbers in
the parts list.
What’s required for the installation?
Screwdriver (large).
Ø8.5 mm. drill.
Ring spanner to match nuts.
5 x M6x8 (1/4”) countersunk head screws and corresponding nuts.
5 x large washers or backing plate ø6.

1. Remove screws (1).
2. Remove self-tailing arm (2) and drum (5).
3. Mark location of boltholes using the drilling template RD100516 or RD100213.
4. Remove complete winch. Be sure that no dust comes into contact with the winch while drilling.
5. Drill the bolt holes Ø8.5mm (11/32”).
6. Apply a light coat of bedding compound, ensuring that each bolthole is bedded.
Keep drain grooves clear.
7. Fasten lower base (22) and cover (23) into place using 6 pcs. M8 (5/16”) countersunk head screws. Use
large washers or a backing plate.
8. Assemble in reverse order.
9. 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 fast.

balls.
5. Remove screws (10).
6. Remove upper base (13).
7. Remove roller bearing (12).
8. Remove screw (15), shaft (19) and gear wheel (20).
9. Remove shafts (16)
10. Remove and dismantle the two Ratchet gear units (17, 18).
11. Clean all parts in Benzine. Remember to clean the gear teeth, roller bearing track and all ball track inside
the drum (5).
12. Assemble in reverse order. During assembly, lightly grease all gear teeth, drive shaft, roller bearing,
shafts, balls, pawls, springs and composite bushings.
Use a small, soft brush. Pawls may be lubricated with either a very thin film of ANDERSEN WINCH
GREASE. It is very important that pawls can move freely.
IMPORTANT: When assembling the winch, check the function of each pawl by pushing the pawl against the
spring. The pawls should smoothly and automatically return to their normal position, where the pawls engage
with the teeth. If the pawls do not function correctly, clean and lightly lubricate the pawls and gears again and
replace the springs where necessary.
Malfunctioning pawls may lead to unexpected failure of a loaded winch resulting in material damage or serious
personal injury.
