1.0 INTRODUCTION
1.1 PRE-INSTALLATION NOTES
• Read this manual thoroughly before installation
and using the windlass. Failure to adhere to
the correct procedures, recommendations and
guidelines described in this Owner’s Manual
may invalidate the warranty.
• Be mindful that the correct selection of
windlass for each application, together with
correct installation, normal care in use and
maintenance, are essential for long life and
reliable performance.
• Inspect your windlass carefully when unpacked.
Any damage or lack of components should be
reported immediately to your Maxwell distributor.
• The windlass is supplied with chainwheel, as
specied on purchase order. Make sure it is the
appropriate one for the chain being used on
board. Correct t of the chain to chainwheel is
essential for reliable and safe operation of the
windlass. This can be guaranteed only when
calibrated chain to a recognised international
standard is used and the chain is correctly
identied to Maxwell, or if a chain sample
is provided to Maxwell to develop a custom
chainwheel.
• The windlass is designed for use in conjunction
with chain stopper and tensioner of the
appropriate size. Their use is an important safety
feature.
• For side pocket anchors, a chain roller should
be installed above the hawse pipe to ensure
smooth and quiet travel of the chain from deck
to hawse pipe. The roller requires a central
groove to align chain and at faces (for longer
chains) to support and avoid bending the chain
links.
• The connection of the power lines and control
circuitry to the windlass must be done by
skilled technicians, to ensure reliable and safe
operation of the windlass.

2.0 INSTALLATION
2.1 SELECTION OF POSITION FOR THE WINDLASS
Windlasses of this size will often be installed in
pairs, giving an emergency backup in the event of
mechanical or electrical failure. In this case one of the
windlasses will normally be retrieving anchor running
clockwise and the other anticlockwise.
Position of the windlass should be selected together
Denition of rotation
The windlass is called a “clockwise windlass” if
it rotates clockwise, viewed from above, when
retrieving the ground tackle.
with positions of hawse pipe and spurling pipe.
The deckplate should be installed pointing with its
narrower end in the direction of the incoming chain.
That allows the chain to have maximum engagement
with the chainwheel.
Allow the chain a straight run from the bow roller to
the chainwheel with no more than a 2° deviation from
horizontal (Picture 2.1).
The bow roller should have a vertical groove to suit
the prole of the chain. Its centre line should be
tangentional to the chainwheel (Picture 2.2). This
will align the chain so that it enters the chainwheel
without twisting.
When positioning the windlass, make sure that there
Direction of chain entering the chainwheel
is room to swing the clutch lever, so that it will clear
the pulpit and life lines or bulwark.
The tting of a chain stopper is essential to take the
load off the windlass while the vessel is at anchor. It
must be correctly aligned with the direction of chain
and installed at appropriate height to avoid the chain
rubbing over chain stopper body or pawl. Make sure
the chain stopper clears the anchor stock.
A tensioner device to tension the anchor into its
pocket is recommended. If the anchor is not snug in
the pocket, it could cause damage to the pocket in a
heavy seaway.
Correct height of Chain Stopper
Ensure a minimum of 800mm (32") clearance
between the end of spurling pipe and the chain piled
up in the chain locker. This will assist kinks, which
may develop in outgoing chain, to shake free.
The chain must gravity feed into the locker. If the
chainpipe cannot be positioned directly over the
locker, a heavy wall pipe can be used to direct
the chain to the required area. It is important that
the chain slips through the pipe easily, completely
unaided, sharp corners should be avoided. It may
be necessary to provide the pipe with a bell mouth
or to bell mouth the entrance to the chainpipe from
the locker to assist the free ow of the chain from the
locker.
The chain locker must be of such a size and shape
that the chain will heap up and feed out naturally
without fouling.
Recommended free space in chain locker
Picture 2.1
Picture 2.2
Picture 2.3

If it can be arranged, the chain locker bulkhead should
pass between the chainpipe outlet in the deckplate
and the gearbox. This will keep the gearbox, motor
and power lines dry and away from aying chain.
Access for servicing from inside the cabin area can
usually be arranged through a locker.
Note that the gearbox can be indexed through a
number of different angles in relation to the windlass
deckplate. Be sure to select the most convenient
arrangement at installation and ensure incoming
chain well clears the gearbox, motor and power
supply lines.
To ensure safe position of the operator while tailing
from the warping drum, footswitches should be
positioned at least 500mm (20”) away from the
windlass.
The below deck portion of the footswitch should not
be exposed to water or wet environment and the
breather holes must be kept clear. The arrows on
the footswitches should be arranged to indicate the
direction of operation.
The motor starter (solenoid valves for hydraulic
windlasses) should be located in a dry area in close
proximity to the windlass. It must not be located in the
wet environment of the chain locker.
The breaker/isolator panel (DC powered windlasses
only) is selected to provide limited overload protection
for the motor and full protection for the supply cables.
It also provides the means for isolating the electrical
system from the battery.
This should be mounted in a dry place within 1.8m
(72”) of cable length from battery.
This equipment or equivalent is mandatory to meet
U.S.C.G. requirements.
Picture 2.4
Positions of drive, relative to topwork
2.2 PREPARATION OF MOUNTING AREA
It is of paramount importance that the vessel has
sufcient deck reinforcing and total structural strength
to sustain the loads that can be transmitted to the
mounting area of the windlass and chain stopper.
This should be equal to the loading of the equipment
to beyond breaking strength of the chain.
The mounting area for the windlass must be perfectly
at and rigid. A structural grade ller can be used
to level this area if initial atness is inadequate.
Mounting area for the chain stopper should be
prepared at the same time. The chain stopper has to
be installed at an appropriate height to ensure that
chain lays horizontally when it comes out of the chain
Page 10
stopper and into windlass. Maximum allowed angle
deviation in vertical plane is ±2°.
If hawse pipe is angled outboard from deck to anchor
pocket, the chain stopper should also be angled by
half of the angle of the hawse pipe (Picture 2.5). That
will help to reduce twisting of the chain between the
chain stopper and the windlass and ensure good t of
the chain into the chainwheel. The chain stopper can
be installed vertically if the hawse pipe angle is less
than 4°.
A deck cutout detail drawing is enclosed with these
instructions to assist in marking out all the drilling and
cutting required for installing the windlass. Before
drilling and cutting, check the marked out area is
dimensionally correct and make any necessary
corrections.
The hole for mounting band brake guide (where
applicable) should be marked and drilled after
assembling the band brake on the windlass.
10
2.3 PREPARATION OF THE WINDLASS
Remove windlass from its packing case.
Disassemble it in the following order (refer to
drawing in Appendix B):
• Remove the Cap and O-Ring from the top of the
windlass, taking care not to damage the chromed
surface.
• Undo and remove the Retaining Screw and
Retaining Washer under the Cap, using a at
screwdriver.
• Undo and remove Clutch Nut, remove Drum and
Upper Clutch Cone .
• On VWC & VWCLP versions, undo Screws that
retain Chainpipe and remove it. On VW versions
undo Screws and remove Stripper.
• Remove Plungers, springs, upper spring holder,
Chainwheel, Lower Clutch Cone and Key. The
Lower Clutch Cone might be held by a Grub
Screw to the shaft. If that is the case, undo the
Grub Screw before removing the cone. Make sure
not to displace the two Retention Clips that were
supporting the Lower Clutch Cone.
• Carefully remove Deck Seal to avoid damage to
it.
• Undo Screws and remove the Deckplate.
• Refer to Appendix B of this Manual and identify
all parts. If any parts are damaged or missing,
contact your Maxwell distributor. Some smaller
parts might not be assembled on the windlass
by the factory, but supplied in a plastic bag in the
packing case.

Maxwell strongly recommends generous application
of a high quality anti-corrosive paste or coating to
the mating sections of main shaft, drive key, anges,
screw threads, dowels and other surfaces that are
likely to seize after being in contact for a prolonged
period of time.
Also ensure anti-corrosive coating is liberally applied
to the inside wall of the Spacer Tube.
2.4 INSTALLING THE WINDLASS
Refer to the drawing in Appendix B for help with
identifying components and installing them correctly.
Extra care should be exercised when handling
polished parts to avoid any damage to polished
surfaces.
When assembling the parts, apply an anti-seize
compound generously over all screw threads, keys
and keyways, Mainshaft and inside the spacer tube.
Proceed with installation in the following order:
• After cutting holes for the windlass in the deck,
apply an appropriate bedding/sealing compound
to the clean surface, place Deck Gasket and
bolt the Deckplate to the deck using Mounting
Screws, and Insulating Bushes. Tighten them
evenly to 80 Nm (60 ft lb). Heel Block should
already be assembled to Deckplate.
• Offer up, from below deck, the drive assembly
sliding the Mainshaft through the Deckplate,
taking care not to damage the deck bearing.
• After aligning them correctly, bolt the Deckplate
and Spacer Tube together, from above deck,
using the Hex Head Screws and Spring Washers.
Tighten them evenly to 80 Nm (60 ft lb).
• Re-check that the position of the drive assembly
is satisfactory and convenient for connecting
power supply lines to the motor. Also, make sure
that the drive is not in the way of chain coming
into the locker.
• If a chain counter is used, its sensor should be
tted into the Ø15mm hole in the Deckplate,
currently covered with a Plastic Plug. Make sure
the deck is drilled below for the sensor cable.
See brochure supplied with Chain Counter for
detailed assembly instructions.
• Grease Deck Seal and carefully slide it down
the Mainshaft. Push it against the Deck Bearing
(28) by approx 1.5 mm after initial contact (see
Picture 2.8).

• Insert the two Retention Clips into the groove in
the Mainshaft; apply some grease to help keep
them in position.
• Apply anti-seize compound generously over
the Mainshaft and keyway. Insert Key into the
keyway in the Mainshaft.
• Assemble the Lower Clutch Cone making sure it
sits nicely on the retention clips (see Picture 2.9).
Apply Lithium based marine grease generously
to the conical surface of the Lower Clutch Cone,
to assist with free falling the anchor.
• Install 6 springs and Plungers into holes in the
Lower Clutch Cone.
• Install Chainwheel, Upper Spring Holder and the
remaining 3 Plungers and springs.
• Install Band Brake (if applicable) on the
Chainwheel, putting its two stops one each side
of Heel Block. The Band Brake can be assembled
with its handle pointing either direction, choose
more convenient option.
• Make sure the band sits at on the shoulder at
the lower end of the Chainwheel and tighten the
brake by turning the Lead Screw. Slide shaft
guide (5 – Band brake) on Handle Shaft (6
– Band brake). Line up both parts of the Lead
Screw Assembly in one vertical plane and make
sure the bottom surface of the Shaft Guide sits
at on the deck.
• Mark up the position of the Shaft Guide on deck,
then remove the guide and drill Ø13mm clearance
hole in the deck for the retaining screw (not
supplied). The Shaft guide has a mounting hole
M12 x 25mm deep and should be retained from
under the deck with a M12 bolt of appropriate
length (depending on the deck thickness).
• Apply the same bedding/sealing compound as
used under the deck plate, replace the Shaft
guide and retain it from underneath.
• Slide the Retaining Nut (2 – Band brake) on
the Shaft (6 – Band brake) and insert the Pin (3
– Band brake) into the hole in the Shaft. Then put
on the Handwheel (1 – Band brake), making sure
the end of the Shaft comes into the square recess
in the Handwheel, and fasten it with the Retaining
Nut.
• Install Chainpipe and retain it with the 3 cap
screws. Note that there are three Spacers
supplied for the Stripper. They should be used
to adjust the position (height) of the Stripper.
The correct height is when the Stripper is in, or
as close as possible to the centre of the central

• Slide Upper Clutch Cone. Note that this cone has
friction lining, which SHOULD NOT be greased,
unlike the lower cone.
• Assemble Drum on top of the clutch cone (VWC
models only).
• Assemble Clutch Nut.
• Put Retaining Washer on top of the Mainshaft
and secure it with the Screw.
• Insert Cap into the Clutch Nut.
2.5 SELECTION OF MOTOR STARTER
Several AC motor starter options for windlasses are
available, each with characteristic current demands
and start load limitations. Maxwell recommends that
selection of the best motor start system be entrusted
to experienced persons familiar with anchoring
procedures and the vessels generating capacity.
"Direct On Line" starter is the simplest way of starting
an AC motor and it will allow the windlass to start
under full rated load. However, this method requires
relatively high momentary starting current, which the
generators may have adverse effect to the rest of
the electrical system on board. See specications
for current values at 400V in Section 1.3 and make
sure to recalculate it for the voltage used on board.
Start current may be limited to about half the above
amount by using a "Star-Delta" starter. However, start
torque is thereby limited to loads of about 25-30% of
the windlass rated capacity.
“Star-delta” and “soft starters” are not recommended
for starting windlass motors, as the motor torque is
severely limited during start up period. Since these
motors often have to start under load (when retrieving
the ground tackle), they might not be able to move
until they reach the full voltage and torque. The
benet of starting at lower current would therefore be
lost. Also, the motor brake would release immediately
on start-up, which could cause short movement of the
chain in opposite direction.
The Variable Frequency Drives (VFD) offer accurate
control of current during start up period while keeping
high motor torque. They also offer various other
benets like:
• innite speed control
• running the windlass over its nominal speed
• accurate current overload and thermal overload
control
The selection of the type of motor starter
should be done by a qualied electrical
engineer, taking into consideration the power
generating capacity on board.
Maxwell offers both advice and different types
of custom made starters to complement our
windlasses.
The “up” and “down” start contactors must
be mechanically or electrically interlocked
to safeguard the motor, in the event that an
accidental attempt is made to start the motor
in both directions simultaneously.
Page 14
14
Both “Direct On Line” starters and Variable Frequency
Drives are suitable and available from Maxwell,
customised to suit the anchor windlass and stern
capstan application.
2.6 POWER CONNECTIONS TO AC MOTOR
Remove the motor terminal box cover and take care
not to misplace the sealing gasket and screws.
Select a suitably sized, waterproof cable gland for
the armoured supply cable. The selected gland tting
must t the terminal box, be capable of anchoring the
armoured cable, and allow an effective waterproof
entry seal to be made.
Make the line connections to motor terminals. Make
also an effective earth connection.
Separately and similarly, enter the 2 thermistor cables
to the motor terminal box, and connect to the two
auxiliary terminal connectors of the thermistor circuit.
Check:
• Is the direction of rotation of the motor correct?
• Are cables satisfactorily xed?
• Are cable entry points to motor terminal box
satisfactorily waterproofed?
Spray the cable gland, cable entry points and motor
terminal box with anti-corrosive waterproof coating
"CRC 3013 Soft Seal" or equivalent.
Page 15
15
2.7 POWER CONNECTIONS TO DC MOTOR
The main power system is a two cable, ungrounded,
fully insulated, negative return system. The motor is
of the isolated earth type. This system is selected to
minimise electrolytic corrosion problems.
The DC motor has four power terminals, marked 1-4.
They should be connected to the starter box as per
schematic P101807 in Appendix C.
After connecting the cables, spray all terminals with
anti-corrosive waterproof coating, “CRC 3013 Soft
Seal” or equivalent.
2.8 POWER CONNECTIONS TO HYDRAULIC MOTOR
A basic hydraulic schematic is shown in Appendix C.
Port sizes on the hydraulic motor and minimum hose
sizes are specied in Section 1.3.
The motor is supplied with oil through two ports on
the Counterbalance Valve Block. They should be
connected to a bi-directional, solenoid controlled valve
(not supplied by Maxwell). The pressure line (when
retrieving the anchor) should be connected to the port B
and the return line to the port A (see Picture 2.8).
After connecting the power lines, spray all ports and
ttings with anti-corrosive waterproof coating, “CRC
3013 Soft Seal” or equivalent.
Page 16
2.9 INSTALLATION OF CONTROLS
The windlass can be operated using:
• Deck mounted footswitches
• Hand held pendant controller (single or dual
speed)
• Helm switch (single or dual speed)
• Chain counter
These control accessories are available from Maxwell
customised to suit your windlass.
It is the choice of the designer/builder to use one,
two or all three of these controls. They are wired
in parallel to the directional valve (for hydraulic
windlasses) or to the starter unit (for electric
windlasses). The controls can work on 12 or 24V
power supply.
If footswitches are used, then an isolator switch for
them must be installed in the wheelhouse, to prevent
operating the windlass by someone accidentally
stepping on the footswitch.
Hand held pendant controller is often the most
convenient way of operating the windlass. Maxwell
offers several variations of pendants, including single
speed, dual speed, single pendant for running a pair
of windlasses, pendants with auxiliary buttons which
can be used for starting chain wash system, hydraulic
pump etc. They are supplied with a plug on the other
end of cable and a matching waterproof socket,
which should be installed on a convenient location
on the deck.
All units are supplied with detailed wiring instructions
to assist installation.
Refer to wiring schematics in Appendix C for control
circuits. All control wiring should be done using no
smaller than 1.5mm² wire (AWG 16).
Where applicable, a manually resetable, ignition proof
3A breaker or fuse should be installed on the power
supply line for controls, within 1m (40”) from the main
breaker/isolator. These requirements are mandatory
to meet USCG, ABYC and NMMA rules.
After connecting the power lines, spray all ports and
ttings with anti-corrosive waterproof coating “CRC
3013 Soft Seal” or equivalent.

2.10 NOTE TO BOAT BUILDER
Experience has shown that, on long ocean
deliveries, sulphur from the ship's exhaust can settle
on polished surfaces, which can affect the quality of
the nish.
Please ensure that, upon completion of installation,
the windlass is treated with suitable corrosion
protective coating (“CRC 3097 Long Life”) and
wrapped in plastic lm. This ensures that your
customer receives the windlass from you in the
same top quality condition as you received it from
Maxwell.
Page 18
3.0 USING THE WINDLASS
3.1 PERSONAL SAFETY WARNINGS
• As with all load carrying equipment, the
consequences of heavy overload, neglect or
misuse may be unexpected failure and exposure
of crew and/or vessel to risk. Operate the
windlass with extreme care at all times.
• Before testing the windlass for the rst time,
check that all the wiring has been done correctly.
• When using the windlass, at all times practice
good seamanship and adhere to the following
rules in order to avoid any likelihood of injury or
accident.
• At all times keep hands, feet, loose clothing,
cordage and your hair WELL CLEAR.
• Never operate the windlass from a remote station
without maintaining a clear view of it and having
made sure that everyone is well clear of the
windlass, anchor and chain.
• Never use the windlass under power with
the clutch handle inserted into clutch nut or
emergency crank collar.
• When engaging the pawl while chain is running,
keep ngers away from the chain. Use clutch nut
lever, underneath and guarded by the chainpipe.
• Always motor up to the anchor position before
retrieving it from the bottom. Do not use the
windlass to pull the boat to the anchor.
• If the anchor is fouled, do not use the windlass
to break it out. With the chain stopper taking the
load, use the boat’s engine to break the anchor
loose.
• When lowering the anchor under manual control,
use the band brake or friction clutch (if tted) to
control the speed of the chain. Never lower the
anchor without maintaining safe chain speed.
• When the windlass is not in use, make sure the
power supply is isolated, making an accidental
operation thereby impossible.
• Do not use the windlass as an anchoring point
for the chain. Engage the chain stopper when the
windlass is not in operation.
• Never proceed at speed without rst ensuring
that the chain stopper is engaged. Also engage
the tensioner to keep the anchor snug in the
pocket.
• When using the windlass, do not switch
immediately from one direction of rotation to the
other, without waiting for windlass to stop. Abuse
is not covered by warranty.
Page 19
19
3.2 LOWERING THE ANCHOR UNDER POWER
• Ensure the clutch is fully engaged by inserting the
clutch nut lever in one of the slots on the clutch
nut, and turning clockwise rmly. The windlass
is equipped with a friction clutch, so it can be
engaged in any position (there is no need to
match the position of the opposite sides of the
clutch before engaging it).
• Remove clutch handle.
• Release band brake or pawl (whichever is
tted).
• Disengage chain stopper and chain tensioner (if
tted). To disengage the chain stopper pawl the
windlass may require momentary jogging in the
up direction.
• The windlass may now be lowered under power
by operating either the hand held pendant control,
helm switch or footswitch.
• When nished, turn off the isolator switch for the
controls.
3.3 RETRIEVING THE ANCHOR UNDER POWER
• Ensure the clutch is engaged, as described
above, and band brake or pawl is released.
• Remove clutch handle from the clutch nut.
• If a pawl type chain stopper is used, it can be left
ratchetting on the chain, so it will engage itself
automatically when the windlass stops.
• The windlass may now be operated to raise the
anchor.
• After retrieving the anchor make sure the chain
stopper and tensioner are engaged.
• Turn off the isolator switch for the controls.
As a safety feature all buttons on the controls
(pendant, toggle switch or footswitch) are
non-latching and the windlass will continue to
operate up or down only while they are held in
the engaged position.
Picture 3.1
Engaging the clutch
It is regarded as sound practice to motor
over the anchor position and so reduce chain
tension. This will also help the anchor to break
out, reduce the power consumption and reduce
load on the windlass and deck gear.
Care should be exercised when docking the
anchor to avoid damage to the anchor pocket.
Jog in the last meter (3-4’) of the chain
carefully seating the anchor home.
3.4 LOWERING THE ANCHOR UNDER MANUAL CONTROL
This method will normally be employed to lower
the anchor quickly, to lower it in "quiet ship" and in
emergencies (power loss or control failure).
Proceed as follows:
• Tighten the clutch and band brake (if tted).
• Release the chain stopper and chain tensioner.
If the anchor has to be lowered in case of power
loss and pawl on the chain stopper is engaged
and under tension (by chain), to release it, pull
the chain in slightly, using tensioner. Once the
pawl is disengaged, release the tensioner and
Page 20

disengage it. If there is too much slack in the
chain, it might be necessary to remove the domed
nut from the end of lead screw and release the
It is considered potentially dangerous to allow
the chain to free fall in an unrestricted manner
- always control the chain speed.
screw completely. If doing that, make sure the
band brake and clutch is still engaged, for safety
reasons.
• Fully disengage the clutch by turning the clutch
nut anticlockwise until it comes to a stop.
• Slowly release the band brake in a controlled
manner. The chain should now release, the
weight of self-launching anchor being sufcient to
draw out the chain. Regulate the chain speed by
gradually engaging/disengaging the band brake.
• When the required amount of chain is out, tighten
the band brake and engage the chain stopper.
• If the band brake is not tted, the speed of chain
can be controlled by the clutch. In that case, after
disengaging the chain stopper, slowly release the
clutch by inserting the lever into the clutch nut
and turning it anti-clockwise. Regulate the chain
speed by gradually engaging/disengaging the
clutch.
Chain Roller-Stopper-Tensioner
The chain slack between the tensioner and
the windlass should be kept to less than the
end travel of the tensioner. This allows for safe
disengagement of the tensioner and transfer of
load to the chainwheel.
3.5 OPERATING THE WARPING DRUM INDEPENDENTLY
This is applicable to VW and VWC models only.
The drum can be operated independently of the
chainwheel and can be used to manage docking
lines or a second anchor. To use in this way, proceed
as follows:
While handling docking lines with the capstan,
ensure everyone stays well clear of the lines
and the capstan.
• Engage the chain stopper, the pawl or the band
brake (whichever is tted).
• Fully disengage the clutch as described in
Section 3.4.
The drum may now be operated independently of
the chainwheel. Maxwell recommends all warping
operations be controlled by the footswitch. This
makes it a one-person operation and offers better
control of the capstan in case of emergency.
Take several turns of the warping line around the
drum and pull on the rope tail with sufcient manual
force to provide good grip of the line to the drum,
Take care not to allow “riding turns”. This is
caused by the loaded line climbing on top of
lower loaded coils on the drum. A riding turn
can only be removed by paying the line out to
the point where the riding turn is created.
whilst operating the footswitch. Make sure the drum is
operated in the same direction as the line is wrapped
around it.
Do not engage more turns on the drum than are
necessary to accomplish the task. Whilst docking,
wind and tide can impose sudden and excessive line
tension. It is recommended to allow slipping to occur
at the drum. This will protect the capstan, docking
lines and vessel from damage.

4.0 MAINTENANCE
4.1 WINDLASS MAINTENANCE
21
Every six months disassemble the above deck
components of the windlass (up to the Deckplate) as
described in Section 2.3. Clean all components and
check for damage. Grease the components using
lithium complex base, water proof grease, especially
grease the conical surface on the Lower Clutch Cone,
Upper Clutch Cone has a friction lining and should
not be greased. Grease bearing in the Deckplate
through the Grease Nipple.
Clean chromed surfaces with a cloth, damp with
kerosene. After cleaning spray them with “CRC 3037
Long Life” or alternatively, with “CRC 6-66” or “WD40”. Regular use of “CRC3097 Long Life” will assist in
maintaining the bright chrome nish.
Re-assemble in the reversed order.
Inspect the components below deck for corrosion,
chipped paint etc, clean them, touch up the paint if
necessary. Spray them for protection with “CRC 3013
Soft Seal”.
The gearbox on electric windlasses is lubricated for
life and, as such, does not need periodical oil change.
Once installed correctly, it should give many years of
trouble free service without maintenance.
If, for any reason, the oil in the gearbox has to
be replaced, use Shell Tivela Oil SC320. If not
available, another synthetic oil of equivalent viscosity
characteristics can be used.
The gearbox on hydraulic windlasses is lled with
synthetic oil, which should be changed every three
years. When changing the oil, take the gearbox of
the windlass together with the motor because motor
ange acts as a seal to the lower end of the gearbox.
Turn the gearbox up side down and then take the
motor off. When the new oil is lled up, the oil level
should be up to the centre of the Sight Glass (refer
– Gearbox assembly – appendix B).
Before doing any maintenance work on electric
motor, starter units and wiring, make sure the
power supply is switched off.
Use synthetic oils only. Never mix two oils, even
if they are from the same manufacturer.
Page 22
4.2 BAND BRAKE MAINTENANCE
The frequency of brake lining renewal will depend
entirely on its usage. Should visual inspection reveal
that the lining thickness has worn to below 2mm or if
the ends of brake band can touch each other when
tight, renewal of brake lining is necessary.
Grease the band brake lead screw at least every
three months.
Avoid grease contamination of brake friction linings.

4.4 SPARE PARTS
Maxwell recommends a modest quantity of spare
parts to be ordered as familiarity with the windlass is
developed during installation. As small parts can be
lost during maintenance, keeping spares (and spare
tools) is recommended.
