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 capstan or vessel when retrieving the anchor, it is a preferred practice to mark the
rope/chain at approximately 5-meter intervals from the anchor, to alert the operator to the anchor position.
Under no circumstances should the windlass be operated if it is stalled or overloaded.
SAFE OPERATION
•Ensure that hands, feet, hair and clothing are kept clear of the windlass and other loose gear when in
operation.
•The capstan should never be used for lifting people aloft.
•Do not use a capstan as a bollard for mooring, towing or being towed.
INSTALLATION INSTRUCTIONS
Locate the capstan in a suitable position on the deck so there is no interference from other ropes or objects
(the rope has a clear lead to the winch), so that there is working room and you can tail the line confortable.
Ensure that there is sufficient room to run the electrical cables to the winch underneath the deck.
If the deck is angled or curved a suitably shaped mounting block will be required to spread the load evenly
over the deck surface and mount the winch on a level and even footing. Depending on the thickness of the
deck, a suitable spacer below deck may be required to mount the winch. Place the shaped mounting block
(if required) onto the deck. Use the layout template dimensions to mark the hole centres and then drill/cut out
the holes.
Apply an appropriate sealant to the base plate and mounting block (if required), taking care to align
mounting holes when assembling. For Aluminium or Steel hull vessels, it is important to insulate the
capstan 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. Install and tighten mounting bolts.
For recommended Electrical installation, please review electrical section.
HANDY HINTS
Ensure sufficient room to run electric cables to the capstan winch. Follow the instructions above including
underdeck stiffening, alignment, mounting blocks and sealing procedures.
Position the capstan carefully checking desired rope path before mounting capstan to your deck.

There are no absolute rules about winch size to boat size. This product is designed for use on
t pical private pleasure craft. Winch / boat sizes shown are based on installations that have
proved satisfactor for man ears.
ELECTRICAL
See Wiring Diagrams for wiring instructions.
Circuit breaker (must be fitted to ensure warranty)
If the drum winch is overloaded or stalled the circuit breaker automatically cuts off power to the winch
and protects the wiring and motor. The circuit breaker should not be used as an isolating switch, for safety
reasons.
Deck Switches are best located to either port or starboard or directly behind the capstan 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 capstan as possible. Larger cables will reduce the voltage drop
to the motor and the heat generated when operating the winch. Small diameter cables drop voltage
considerably. Use the following table as a guide to your required wire size: (Based on 1500W 12V Motor)

Solenoid 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 winch.
For wiring information, please refer to the wiring diagram/schematic.

OPERATING INSTRUCTIONS
It is adviseable to “mark” the anchor end of the chain/rope at 2 and 5 metre (6.5’ & 16.5’) intervals which will
enable the operator to judge when the anchor is almost up.
Anchoring: Lower the anchor as you reverse the boat, this allows the anchor and chain to layout properly on the
sea bed. Lower the anchor until the rope is slack and/or you are in the right position, once there it is
recommended to tie off the rope to a cleat or bollard, or use a snubber.
To retrieve/raise the anchor, stand or kneel behind the winch and simply wind up to three turns (maximum) of
line or sheet around the drum in a clockwise direction. Maintain a light “tailing” pull onto the free end and
start the capstan. As the capstan rotates, lightly pull the line hand over hand keeping up with the speed of
the winch. The capstan does all the hard work for you. Stop and hold at any time. Do not use your hands or
feet on the anchor side of the capstan drum to adjust the rope as it may become caught and entangled in
the winch drum.
When recovering your anchor, first start the engine.
In strong winds, tides, currents or in deep water, use
a little engine power to come up over the anchor
as the capstan is used. Never stall the capstan and
do not run it at low speed for any extended time.
Use one continuous and smooth recovery and do
not repeatedly start/stop. If the anchor is stuck, use
a little engine power and the weight of the boat to
break it free.
Also take care not to run over the anchor rope and entangle it in your prop or rudder. Go gently with the last
two metres of retrieving the anchor, rather than waiting for the anchor to fly up over the roller and bang tight,
putting excessive load onto the bow roller, winch and fore deck. When the weather is rough, anchoring
overnight or traveling, it is not recommended to use the casptan as a mooring bollard!! Secure the rope around
a cleat or bollard, or use a snubber to take the load.

MAINTENANCE AND SERVICING
Servicing
Every 6 months, remove centre screw from top of the capstan drum and lift drum off.
Lightly grease the synthetic bearings under the drum.
Smear a little grease on the O ring seal in the top outer cap, assemble and tighten firmly.
The motor is made of steel and may corrode if the paint system is damaged.
Check the motor regularly and keep dry and clean.
In “dry” installations, spray the motor regularly with a water repellant (CRC or WD40).
In damp or “wet” installations, including situations where a lot of condensation takes place, treat the motor
and terminals regularly with CRC “soft seal” or similar.
Check all terminals in the system and protect as described above.
In the case of Work and Charter Vesels we suggest it is carried out more frequently.
Line Care
Muir winches 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.
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. (See 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 1/3 and insert two further tucks. Pare down by another1/3 and finish with two tucks.
Cut any remaining tails.

CORROSION PROTECTION - for long life (general notes for all winches).
The motor and some underdeck parts of your winch are manufactured from materials that require protection
from the marine environment. Paint and other protection systems are applied at time of manufacturer, but
additional protection and regular inspection is necessary after installation.
Immediatley after installation we recommend that the winch is tested. Reversing winches should be run in
forward, reverse and manual modes. Rope only winches will only run one way unless ordered otherwise.
Observe polarity indicated by +/- lables on motor. Check all terminals and fastenings are firmly secured. Coat
all underdeck surfaces and terminals with CRC ‘Softseal’, automotive underseal or similar. Control equipment
should never be installed in damp positions such as the chain locker, but, if necessary, control equipment will
need protection too.
Service checks. Check motors and underdeck parts regualary for signs of corrosion and take necessary action
immediately. Above deck items need maintenance too, including cleaning, greasing/oiling per instructions
issued with the winch. If cone cutches (where fitted) are found to stick, release clutch nut and give one of the
gypsy teeth a smart rap with a hard wood or brass drift. When the clutches free up, a very light spray with CRC
/ WD40 will help prevent further sticking.
WARNING. Motor, brake, gearbox assembly should never be removed or fastenings loosened during
installation. Some fastenings are sealed with a locking compound and warranty may be void if any seal is
broken. If a fault is suspected during the warranty period DO NOT remove any parts or attempt a repair. Return
the complete unit to the factory via supplier with evidence of purchase and detail of problem experienced.
FAILURE or DAMAGE due to improper maintanence is not covered by warranty.
ATTENTION !
VC800 Capstan will ONLY work in clockwise direction.
Always connect Positive (+) Terminal on the Battery
to the Positive (+) Terminal on VC800 Electric Motor.
Always connect negative (-) Terminal on the Battery
to the negative (-) Terminal on VC800 Electric Motor.
If wired incorrectly it will damage
the Electric Motor and VOID the Warranty
