INTRODUCTION
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 MZ Electronic distributor.
The windlass is supplied with chainwheel, as specified on purchase order. Make sure it is the
appropriate one for the chain being used on board. Correct fit 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 identified to MZ Electronic, or if a
chain sample is provided to MZ Electronic 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
flat faces (for stud length 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.

Extra care should be exercised when handling polished parts to avoid any damage to polished
surfaces.
Apply an anti-seize compound generously over thread of all screws, before fastening them.
Follow the steps below to disassemble the windlass ready for installation:
1. Unscrew the top cover (2) by turning counterclockwise until it stops. Use the handle supplied.
2. Remove the n.6 M8 capscrews (1) from the top cover (2) and remove it.
3. Unscrew the M8 screw (3) and remove the stop washer (4).
4. Unscrew completely the brass bush (5) until all its thread is out from the main shaft. Two of the M8
screws (1) will be helpful to do this operation.
5. Do not remove the other screws (6)
6. Lift the capstan (7) using the two M12 lifting eyes
7. Lift the chainwheel (9) using the two M12 lifting eyes
8. Remove the key (8).
9. Unscrew the n.10 M12 capscrews (11) securing the drive and mainshaft (13) to the deckplate (12).
10. Carefully slide the drive and mainshaft (13) from the deckplate (12)
To install in the vessel:
1. Cut the hole in the deck as per the deckplate template. All holes must be drilled.
2. Bolt the deckplate in place using an appropriate bedding/sealing compound. Tighten the n.8 M16
capscrews (10) to 150Nm.
3. Fit the drive and mainshaft (13) from below Carefully slide the drive and mainshaft (13) into the
deckplate (12). The lifting eye (M12) can be installed in the end of the shaft to lift from above.
4. Install the n.10 M12 capscrews (10) securing the drive and mainshaft (13) to the deckplate (12).
Tighten to 60Nm.
NB: Confirm the drive and gearbox are clear of the chain and able to be connected to power.
6. Apply grease to the mainshaft (13) and fit the chainwheel (9).
7. Fit band brake assembly (see dedicated section)
8. Grease keyway on main shaft (13) and fit key (8).
9. Slide the capstan (7) onto the main shaft (13).
10. Screw completely the brass bush (5) until all its thread is completely screwed on the main shaft.
Two of the M8 screws (1) will be helpful to do this operation.
11. Fix the stop washer (4) by the M8 screw (3)
12. Fix the top cover (2) by the n.6 M8 capscrews (1). Take care that all the seal are in the right
position and apply grease on all the seal and on the top of shaft.

To install band brake:
Refer to the band brake drawing for identification of components.
1. Open the band brake (1) by turning counterclockwise the handwheel (2).
2. Fit the band brake (1) on the chainwheel.
Note that all the brake assembly can be positioned on either the port or starboard side of the
windlass by turning over the band brake.
3. Slip the heel block (3) into the band brake and position the band brake to the desired location.
4. Make sure the band sits on the shoulder at the lower end of the chainwheel and tighten the band
brake. Line up both parts of the handle shaft in one vertical plane and make sure the bottom surface
of the shaft guide sits firmly on the deck
5. Mark up the position of the shaft guide (4), remove the guide and drill 17 mm clearance hole for
the M16 Stud (5).
6. Apply the same bedding/sealing compound as used under the deckplate, replace the shaft guide
and retain it from underneath, using the M16 Stud (5), washers (6.7) and nut (8).
