INTRODUCTION
Thank you for purchasing a Muir Windlass. Muir go to great lengths to develop anchoring systems that not only
meet all your performance and safety requirements, but at the same time are designed with a style and finish
that enhances the aesthetics of your vessel. With Muir’s commitment to quality and the use of superior materials
and processes we know you will be pleased with your investment, and rest assured that through the correct
installation, operation and maintenance your new Muir Windlass will give you years of reliable performance.
IMPORTANT INFORMATION
To avoid damage to the gear drive, windlass or vessel when bringing the anchor up hard, it is a preferred
practice to mark the chain at approximately 5-meter intervals from the anchor, to alert the operator to the
anchor position. Alternatively an Auto Anchor can be used.
Under no circumstances should the windlass be operated if it is stalled or overloaded.
If anchor retrieval is impaired by high wind, heavy seas or the anchor is snagged, ease the load by either
motoring or sailing slowly forward into the wind with a chain stopping device in place. The rope or chain should
be cleared off and the anchor driven out by the engine, otherwise the gearbox or shaft can be damaged.
SAFE OPERATION
• Ensure that hands, feet, hair and clothing are kept clear of the windlass and other loose gear when in
operation.
• Ensure no one is swimming nearby when the anchor is being lowered or retrieved.
• Keep hands well clear of capstan, gypsy, chain and rope.
• The windlass should never be used for lifting people aloft.
• Do not use a windlass as a bollard for mooring, towing or being towed.
• When the windlass is at lay or the anchor stowed, always ensure the clutch is tightened with the clutch
handle, and a Chain lock, Devils claw or nubber Line is fitted to retain the anchor. The use of these accessories
will prevent excessive loads on the geardrive and accidental release of the anchor.

Figure(1)
Locate the windlass centrally fore and aft. Check that the chain
leads unhindered to the anchor roller. The chain leads onto the top
side of the starboard gypsy, wraps around 100° and falls below
deck through the chain pipe (hawser). Ensure there is sufficient
room around the windlass to allow full rotation of the windlass
manual/clutch handle (if supplied).
Figure (2)
The centre line of the gypsy must be in the same plane as the
chain lead from the bow roller. If the deck is angled (fore & aft) or
curved (port to starboard) a suitably shaped mounting block will
be required to spread the load evenly over the deck surface and
mount the windlass base on a level and even footing.
Figure (3)
Place the shaped mounting block (if required) onto the deck.
Using the layout template supplied, mark the mounting centres
and drill the holes 11mm (7/16”) for the deck bolts of 10mm (3/8”).
(Refer template). Mark the chain pipe centres at this time. (Refer
Chain Pipe Fitting Pg5).
Figure (4)
Apply an appropriate sealant to the base plate and mounting
block (if required) and carefully tighten the nuts & washers onto
the deck bolts under the deck. Remove excess sealer.
For Aluminium or teel hull vessels, it is important to insulate the
windlass with a non-conductive gasket to avoid corrosion. This also
applies below deck with the mounting bolts, nuts and washers.
Where the deck construction is light or of foam sandwich
construction, a plywood stiffener of at least 16mm (5/8") should be
fitted to the underside of the deck to spread the load and to
prevent the bolts from pulling through the deck. Large diameter
washers on the underside of the stiffener assists to spread the load.
Figure (5)
1. Mount the windlass from above as shown.
Figure (6)
2. From below, place washers and nut on each stud and tighten.
For fitting of the chain pipe or RCM see next page
NOTE: On assembly, grease all moving parts with a Lithium/teflon based grease.

Horizontal Winch Chain pipe Fitting
1. To position the chain pipe (A), first align the stripper (B) with the
centre of the gypsy.
2. Wrap the chain (D) around the gypsy (C) and through the
chain pipe to position the chain pipe correctly.
3. Align the stripper to the inside of the chain as it falls vertically
into the chain locker.
4. Mark the chain pipe position and drill the bolt holes, finally cut
out the section for the chain to pass through the deck and
then bolt the chain pipe into place.
Horizontal Winch Chain pipe with Rope/Chain Management System Fitting
1. Position the chain pipe (A) so that the peeler (B) is directly
under the centre of the gypsy (C), and the finger sits on top
(D).
2. lide the / stripper (E), over the middle of the gypsy lining it
up with the hole in the peeler for the screw (F).
3. Fit the stripper with the screw making sure the countersunk
head is inside the chain pipe. Tighten with washer and nylock
nut
4. Check the position of the chain pipe and make sure the
stripper does not hit the gypsy when it is rotating. pot the
holes for the chain pipe on the deck with the chain pipe in
position. Remove the chain pipe and drill the mounting holes.
Refit the chain pipe, checking its position again, and fasten it
to the deck.
5. To tension the rope finger, loosen the grub screw (G), behind
the finger in the chain pipe, and turn the pin (H), towards the
gypsy with a large screwdriver, retighten the grub screw.
Manual Overri e System (MORS)
This allows the operator to manually recover the anchor and anchor rode without the use of the electrics. For
manual operation the locking pawl should be first engaged into the gypsy, this stops the gypsy from running
back wards, the clutch should be released marginally by turning in an anti-clockwise direction. Now the gypsy is
free to turn and the manual override handle can be moved in a clockwise direction to engage the gypsy, when
pulling in an anti-clockwise direction the MOR pawl will engage and drive the gypsy retrieving the chain, as the
handle is moved clockwise the weight will be taken by the locking pawl.
Rope/Chain Management System (RCMS)
Optional chain pipe kits (with pipe, special 180 degree stripper and spring loaded finger) are available. The rope
finger pawl guides the rope and chain around the gypsy and through this special chain pipe.
The standard chain pipe with its integral stripper is normally supplied when otherwise specified or ordered by the
customer.
A justment: Firm tension of the finger is required to reduce rope (nylon Line) slipping through the gypsy. Check
the spring tension (at least) annually and re-tension the spring when needed. To adjust this tension (if your line is
slipping) refer to the procedure below.
Proce ure:
1. Loosen the grub screw on the chain pipe with an Allen key for finger adjustment.
2. Turn the screwdriver clockwise to tension the spring, while holding the tension re-tighten the grub screw

DEPTH OF THE CHAIN LOCKER
Measuring the vertical distance (minimum fall) underside of the deck and the top of the completely stored and
heaped anchor rode in the locker will assist in determining the installation to suit your vessel. Refer to the fall
depth diagrams to the left, and the options detailed below. It is also recommended that the chain be directed
to the center of the chain locker.
Vertical Win lass:
The running gear, gypsy and capstan are positioned above
the deck with the motor and gear drive below. Vertical
windlasses operate at best with greater anchor rode fall
than the horizontal windlass and a minimum fall of 300mm
from top of stacked anchor rode is recommended. This is
particularly important if using nylon line, which does not fold
and stack as well as chain. Vertical windlasses minimise
deck intrusion and the modern curved lines of the Muir
windlass enhance the look of any vessel. A vertical windlass
provides the advantages of a I 80-degree wrap of the
anchor rode around the gypsy.
Horizontal Win lass:
Fully enclosed, above deck, this style is usually preferred
where locker space is limited or additional fall is required.
The motor and gear drive is fully enclosed in the housing
with nothing protruding below deck. The horizontal windlass
operates with optimum anchor rode fall of at least 300mm
from the top of the stacked anchor rode, and due to the
horizontal orientation of the gypsy higher above the deck
there is additional fall provided. These units are ideally
suited for vessels with less locker space.

HANDY HINTS
It is a common mistake to locate the windlass too far forward, or too close to the bulk head, where there is
insufficient room for chain and anchor stowing. The chain fall position should be in the centre of the chain locker.
If the chain falls alongside a bulkhead or onto the stem it will pyramid and jam.
If the chain falls into an undesirable position, a metal tube can be fitted under the hawser to redirect the chain
to a preferred position. This pipe should be at least 1 ½ times the width of the chain. It should also have as much
vertical angle as possible. Position the windlass in the best location with the chain hawser facing forward. Ensure
sufficient room to run electric or hydraulic cables to the windlass. Follow the instructions on page 4 including
underdeck stiffening, deck camber, alignment, mounting blocks and sealing procedures.
ELECTRICAL
ee Wiring Diagrams for wiring instructions.
Circuit breaker (must be fitte to ensure warranty)
If the windlass is overloaded or stalled the circuit breaker automatically cuts off power to the windlass and
protects the wiring and motor. The circuit breaker should not be used as an isolating switch, purely for safety
reasons.
Deck Switches are best located out to either port or starboard or directly behind the windlass in a position
where it can be easily reached with your foot or knee, preferably where you can view the anchor and chain
coming aboard.
Isolating Switch should be fitted in an accessible position for safety, ideally close to the battery or switches. The
isolating switch is not a circuit breaker.
Batteries are best located as close to the windlass as possible. Larger cables will reduce the voltage drop
to the motor and the heat generated when running the windlass. mall diameter cables drop voltage
considerably. Use the following table as a guide to your required wire size:
Distance from battery to motor (m) Cable ize
(mm
2
) AWG Cable Diameter (mm)
7 (23’) 25 3 8 (5/16”)
9 – 17 (30’ – 55’) 50 1/0 10 (3/8”)
Rotation : Windlasses may be wired for single or dual direction, using single or dual deck switches for raising or
lowering. Alternatively a remote control solenoid packages with Toggle witch, Hand Pendant or Auto Anchors
are available.
WINCH MODEL MOTOR IZE MOTOR TYPE

Solenoi Installation
We recommend that the solenoid is installed in an
upright position, where it has no exposure to sea
water and in close proximity to the electric motor of
the windlass.

OPERATING INSTRUCTIONS
Manually Releasing chain: To release the anchor rode, place the handle onto the clutch nut as shown in the
diagram at the bottom of the page and turn anti-clockwise to release the clutch brake. Let the anchor fall
and control the run of the chain by tightening handle clockwise using the clutch mechanism as a brake.
Anchoring: When laying at anchor use a chain stopper, nylon/chain bridle or snubber line to prevent
snatching and direct load on the windlass main shaft. Never use the windlass as a mooring bollard!!
Retrieving Chain: Before operating the windlass tighten the clutch with the handle in a clockwise direction,
then remove the handle. If the anchor is buried hard, motor forward to pull it free after hardening up on the
windlass, to ease the load on the windlass. The rope or chain should be cleared off and the anchor driven out
by the engine, otherwise the gearbox or shaft can be damaged.
Rope Hauling on the Capstan: The capstan can be operated independantly of the gypsy. ecure the anchor
rode (via Chainlock, Gypsy lock or nubber) then release the clutch. The windlass capstan can now be
operated separately.
Electric / Hy raulic operation: Releasing or retrieving the Anchor rode is identical when operating a Hydraulic
or Electric windlass. To release the anchor, down reverse the motor by pushing remote switch to “down” which
drops the chain and the anchor immediately. When the anchor is at the desired depth, the windlass can be
stopped by letting go of the switch, the chain and rope can then be lowered further by releasing the manual
clutch. Always keep well clear of the windlass when releasing or retrieving the chain and anchor. Keep fingers,
hair and clothing well clear when the windlass is in operation.
Auto Anchor Launching: Two direction windlasses are now standard. If the anchor and anchor roller can be
positioned so that it falls as soon as the windlass is reversed, the whole operation can then be carried out
remotely from aft or fly bridge. Remote switch controls are self-centering and stop the windlass when the
switch is released. Mark the anchor end of the chain at 2 and 5 metre (6.5’ & 16.5’) intervals which will enable
the operator to judge when the anchor is almost up. Go gently with the last two metres of retrieving the
anchor by letting go of the switch, rather than waiting for the anchor to fly up over the roller and bang tight,
putting excessive load onto the bow roller, windlass and fore deck.
SERVICING
The geardrive is filled and sealed at factory with long life synthetic oil and does not require replacement.
A rinse of fresh water on all your deck gear after every excursion ensures all salt deposits and corrosion are
kept to a minimum.
Regularly clean the clutch cones and re-apply a thin film of water proof grease to the cone surfaces. This
ensures smooth running of the gypsy and chain when the manual freefall is operated.
We recommend the windlasses of Pleasure Vessels are stripped yearly and all moving parts cleaned and
greased with a Marine Grease, Teflon or Lithium based grease (e.g. Duckhams'Keenol'; 'Castrol LMX'.). In the
case of Work and Charter Vesels we suggest it is carried out more frequently. Do not use soap base grease.

Rope/Chain Splice.
1. To stop rope unravelling, seize rope 400mm(16") from end with
whipping twine. Unlay strands.
2. After placing 20mm (3/4") of heat shrink sleeve tubing through
the last link of chain, pass one strand of rope through sleeve and
chain from one side and the other two strands of rope from the
opposite side. ( ee illustration).
3. While pulling all three strands tight, shrink the sleeve tightly onto
the rope using a hairdryer / fan heater or by immersing in boiling
water.
4. Remove seizing and complete back splice in normal manner for
two full tucks. With a hot knife pare down the three strands by 113
and insert two further tucks. Pare down by another1/3 and finish
with two tucks. Cut any remaining tails.
Line Care
Using the wrong type of line may cause the line to jam causing excessive line wear. Muir Windlasses are
designed to run on 3-strand nylon line (supplied by Muir) which has been specially treated with fabric
softener to prevent it from hardening. It is recommended to soak your rope in fresh water containing
fabric softener every 3 months.
In case of a rope jam, slacken off the windlass clutch to free the jammed line. When retrieving the
anchor rode do not continue to run the windlass if the anchor or chain is jammed, as line slippage in the
gypsy will cause damage to the line.
Trouble Shooting
ELECTRICAL
1. Check the battery circuit breaker and ensure the isolating switch is on.
2. Check battery is charged up to 12 or 24 volts.
3. Check that the foot deck switch plunger is contacting
4. Check remote control solenoid is contacting, if this is clicking the problem may be low voltage, a
faulty solenoid or a wire not properly connected.
5. Check wiring between controls, solenoid and motor are in-tact.
6. If the motor will not turn after checking the above points, check that the motor bushes are not worn or
sticking.
MECHANICAL
If the windlass running gear will not turn or operate check the following
1. Check that the clutch beside the chain gypsy is tightened to the chain gypsy drive using the manual
handle supplied (see operating instructions).
2. If the line slips check the tension on the finger and increase spring tension (see RCM adjustment on
page 5).
HYDRAULIC MOTOR
Refer any problems with your hydraulic motor to a Muir service agent or Muir Hobart.
