6. To release the roller bearing (6), gently insert a small screwdriver between roller bearing
and base plate (8). Remove roller bearing.
7. Remove shafts (12.7, 13.7).
8. Remove and dismantle the two gear units.
9. Clean all parts in white spirits/mineral spirits. Remember to clean the gear teeth,
roller bearing track and bushing inside the drum (4).
10. 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lm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.

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

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/Teon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specic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canbeplacedinseveraldierentpositionsafterhavinginstalledthewinch.
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.
