Wiring Rules
- Values refer to Lofrans circuit breakers only.
- Increase cable section by about 30%–50% when the positive plus negative run is over 10 m (29').
- Control wiring (thin line on the diagram): about 1.5 mm² / 16 AWG.
- Fit a 5 A breaker to protect the remote controls.
- Mount the breaker dry, accessible and visible. Install at least two remote controls.
- If the windlass runs the wrong way, swap M1 and M2 at the control box.

Installation
- Tools: Ø9 mm (3/8") drill, 10 mm and 13 mm A/F spanners, jig saw, power drill, silicone sealant.
- Top part (drum, gipsy, base) above deck; gearbox and motor below. Leave room to work the handle.
- Standard maximum deck thickness 70 mm (2 3/4"); thicker decks, consult your dealer.
- Thin or weak decks need a plywood or timber backing pad. Do not use a stainless steel pad (electrolysis).
- Steel or aluminium boats: insulate top and under-deck parts with a non-conductive gasket.
- Top and under-deck parts must be parallel; misalignment overloads and overheats the motor.
Positioning & Assembly
- Place it over the deepest part of the chain locker, chain running parallel to the deck and wrapping about 180° round the gipsy.
- Leave at least 400 mm (16") between the underside of the deck and the top of the heaped chain.
- Drill using the template supplied. Separate the parts by loosening nuts (227) from studs (533); seal the base bottom and round the studs.
- The under-deck unit can face any of four positions; keep the motor clear of the chain run.
- Join the under-deck part by engaging key (450) on the main shaft in the gearbox keyway; tighten the nuts.
- After first use, check the nuts again.
Clutch & Anchoring
- Gipsy clutch: insert the handle in the clutch nut (273) or gipsy cap (530); clockwise to tighten fully, anticlockwise to free.
- Raising: engine running, clutch engaged, handle removed, press UP. Do not use the windlass to pull the boat to the anchor.
- If the Lofrans breaker trips, wait some minutes before resetting; if it trips again, make the chain fast and use the engine.
- Free fall: release the clutch and control the drop by tightening the gipsy cap. Normally lower under power with DOWN.
- Once anchored, use the chain stopper and/or a rope to a strong point. Switch the breaker OFF and engage the stopper under way.
Drum & Emergency
- Drum only: secure the chain, release the clutch, take two turns clockwise round the drum, press UP while tailing. Re-engage the clutch after.
- Emergency: handle in the clutch nut or gipsy cap, turn clockwise against spring (541). There is no ratio, so deep anchoring is hard work.
- The windlass is not a strong point: fasten the rode to a cleat, bollard or chain stopper when lying at anchor.
- Keep hands, feet and fingers clear of a running windlass; turn the circuit off before clearing a jam.
Maintenance
- Monthly: wash off the salt layer with fresh water, including hidden spots.
- At least every six months: dismantle the top part, clean and check everything, spray with CRC 3097 "Long Life" or WD40, check for electrolysis and grease the main shaft thread.
- After long inactivity the motor may run slowly: check and clean the brushes, replace if needed.
- At least once a year: remove the windlass from the deck and clean the salt from under the base.
- The gearbox is filled with SAE 90 long-life oil. An oil leak means the seals must be replaced; a complete seal set (Kit A) is available.
- Start and end of season: check motor and control box and grease the terminals.
- When ordering spares give the model classification, serial number, item number and quantity.
