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.

ALL WINCHES
Version 3.0
Read All Safety Notices and Product Manuals
Do not install or operate this winch before reading and fully understanding
the contents of this Safety Notice Sheet and the Product Manual.
Version 1.0.F
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 ponts:
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 selftailer 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.
Failure to observe these precautions could result in serious injury or death.
DO NOT DISCARD

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.
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.
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.
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.

Note the curved spring “arm”
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. Nonsuitable grease products can cause malfunction, which could result in fatal injuries for the user and
others.
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.
GENERAL INFORMATION
To ensure the best possible functioning of the winch, we recommend that the winch is placed in
accordance with the line entry shown below.
