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 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.

Tools required for the installation:

Allen key (10 mm.).

Allen key (6 mm.).

Drill Ø12,5mm.

6 pcs. M12 countersunk head screws.

1. Remove screws (20).

2. Remove self-tailing arm (17) and drum (32).

3. Mark location of bolt holes using the lower base (1) as a template.

4. Remove complete winch. Be sure that no dust comes into contact with the winch while

drilling.

5. Drill bolt holes ø12,5 mm.

6. Apply a light coat of bedding compound, ensuring that each bolt hole is bedded. Keep

drain grooves clear.

7. Fasten lower base (1) into place using 6 pcs. M12 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 slowly.

While turning the winch handle anti clockwise the drum should turn fast.

SERVICE INSTRUCTION

Tools required for service:

Allen key (6 mm.).

Allen key (10 mm.).

Screwdriver (small).

Winch handle.

1. Remove screws (20).

2. Remove self-tailing arm (17) and drum (32).

3. Remove drive shaft (16).

4. Remove and clean roller bearings (34) and spacer (33).

5. Clean the balls with a rag. Remove the balls (13)and the small retaining ring (14) above the

balls.

6. Remove screws (37).

7. Remove upper base (21).

8. Remove roller bearing (34).

9. Remove shafts (11,43).

10. Remove and dismantle the three free gear units.

11. Clean all parts in petrol. Remember to clean the gear teeth (42) and roller tracks inside the

drum.

12. Assemble in reverse order. During assemble, 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 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.

Not properly functioning pawls may lead to unexpected release of the winch force resulting in fatal

injuries to the user and others.
