STEP 1 - Positioning the winch and motor unit
STEP 2 - Fitting the deck plate
INSTALLATION INSTRUCTIONS
• Position the winch drilling template [A3] in the required position on the deck, ensuring that there
is adequate flat space for the deck plate/ winch base.
• The 28 and 34 ST winches have only one self-tailing arm position, so it is important to rotate the
winch template to give the required self-tailing arm position (as required for operation, refer page
17). The 40ST winch has the option of eight dierent self-tailing arm positions as indicated on the
drilling template (refer page 18).
• Considering the product dimensions, shown on pages 15 & 16, check that there is adequate
space below deck for the motor unit. You may choose to drill a small pilot hole to indicate the
position of the center of the drive shaft, to assist with this.
*Note: The motor unit can be installed in eight positions around the center of the drive shaft
(i.e. at 45° increments), to facilitate fitting the motor unit into restricted under-deck cavities.
See pages 15 & 16 for the minimum motor oset dimensions at the various positions. Placing the
deck plate on the motor unit in the various positions prior to installation can assist with visualising
the motor position options.
*Note: To ensure the correct functioning of the winch, it should be positioned with the correct
line entry angle of 3-8° below horizontal. Refer to the winch product manual for details of
correct line entry angle and self-tailing arm positioning.
• After it has been confirmed that there is adequate space for the winch above deck, and for the
motor unit below deck;
• Drill Ø6.5mm holes for the M6 deck plate mounting bolts as per the drilling template [A3].
DrillØ9/32”holesif1/4”boltsarebeingused.
• Drill or cut a Ø85mm (3 3/8’’) hole for motor drive shaft housing as per the drilling template.
*Note: Clean the deck hole before attempting the install the motor so that
the motor flange does not catch splinters of fiberglass or wood when being inserted through
the deck. Clean the deck with a suitable solvent to ensure the sealant can adhere properly.
• Apply sealant to the deck where the deck plate will be fitted. For aluminium boats use a galvanic
isolating ring/gasket.
• FitthedeckplatetothedeckusingappropriatelengthM6(or1/4”)countersunkheadbolts,
large backing washers or plate, and Nyloc nuts.

*Note: It is extremely important that the motor is aligned correctly with the winch.
Non-aligned motors will be noisy and gear wear will be accelerated.
*Note: It is important that two or more people are involved with Step 3.
• Remove clamping ring [5] from drive shaft housing [16] of motor unit.
• Fit the supplied M6 eye bolt [A6] to the top of the motor drive shaft [12] and attach a strong
rope to facilitate lifting the motor unit up into position through the hole in the deck, deck plate
and clamping ring as shown below.
• Using the rope, raise the motor unit so that the drive shaft protrudes through the large hole in
the deck and deck plate [7]. A lifting device is recommended when raising the motor unit.
• Rotate the motor unit into the required position to suit the under deck cavity, ensuring that the
motor is aligned properly – The protruding octagonal detail on the drive shaft housing [16] flange
must fit snugly into the octagonal recess in the deck plate to allow the motor top flange to fit
flush with the underside of the deck plate [7] (refer to diagrams below).
*Note: Ensure that the O-ring [8] on top of the drive shaft housing [16] is in place in its groove.
• Insure that the locking grub screw [4] in the clamping ring [5] is not protruding beyond the
upper surface of the clamping ring, when fitting the clamping ring.
• Fit and securely tighten the clamping ring [5] using the pin spanner [A8] provided.
• Tighten the locking grub screw [4] when the clamping ring [5] is securely in place.
*Note: Do not use a sealant between the flange and deck plate. An O-ring insures a waterproof
connection. Extra waterproofing can be achieved by applying sealant to the top of the deck plate
around the clamping ring after installation (make sure no sealant comes onto the sealing ring [8]).

STATUS CODES
TheE1“Intelligent”IlluminatedPushButtonactswiththecontrollertoashstatuscodestoassist
in trouble shooting in the event of overload or where other system protection intervention occurs.
The push button will flash a number of times in quick succession, followed by a short break, and
then repeat again.
The number of flashes indicates the system status as follows:
• 1Flash Maximumworkingloadhasbeenreached.
The motor has cut out after reaching the pre-set maximum load for electrical operation of the
winch. Status will automatically reset to normal and the winch will be ready for use when the load
has decreased below the max limit, and the button is pressed again.
• 2Flashes Lowsystemvoltagedetected.
This will occur if the system voltage goes below 10.5 Volts (for 12V systems) and 21 Volts (for 24V
systems) in idle state, or below 7.0 Volts (for 12V systems) and 18 Volts (for 24V systems) while
running. Batteries should be recharged before the winch is used again. Status will automatically
reset to normal and the winch will be ready for use when the voltage comes back above 11.0 Volts
(for 12V systems) and 22 Volts (for 24V systems).
• 3Flashes Maxtemperatureofthemotorhasbeenreached.
The motor has overheated. Status will automatically reset to normal and the winch will be ready for
use when the motor has cooled down suciently (this may take some time). Ensuring adequate
ventilation around the motor will help to avoid overheating.
• 4Flashes Maxtemperatureofthecontrolboardhasbeenreached.
The temperature of the control board has exceeded 85°C. Status will automatically reset to normal
when the control board temperature drops below 75°C. Ensuring adequate ventilation around the
motor will help to avoid overheating.
• 5Flashes Pushbuttonerror.
Operation of the winch is prevented because a push button has been pressed when system power
up is initiated – i.e. when power is supplied to the winch by closing the CB or battery switch. To
reset status to normal, turn o the power at the circuit breaker or battery switch, ensure no push

SERVICE & MAINTENANCE
*Note: Always shut o power to the winch before commencing any service or
maintenance task!
• The winch on top of the electric motor unit should be serviced as per the instructions
in the relevant Winch Product Manual.
• The electric motor is a sealed unit and does not require regular servicing of internal parts.
• To avoid potential sea water ingress and to maximise the service life of your electric winch motor
unit, it is recommended to re-lubricate the motor unit drive shaft Sealing Ring [9] once a year.
Under intensive use, such as racing, charter or blue water sailing, we recommend lubrication
twice a year.
To access the Sealing Ring [9], it is necessary to remove the winch from the Deck Plate [7].
Refer to the Winch Product manual for instructions.
The Sealing Ring should be lubricated with a grease such as Klüber ISOFLEX TOPAS NB 52,
or Andersen Winch Grease.

SAFETY NOTICES
DO NOT DISCARD
Failure to observe these precautions could result in serious injury or death.
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.
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 points:
• 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 o power before
attempting to resolve the problem.
Avoid Accidental Operation
Remove winch handles and turn o 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 o 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 self tailer 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 o, or leading to a suitable fitting
such as a cleat or bollard.
