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 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.
