Maxwell TASMAN Series Drum Winch — Owner's Manual

Position & Mounting

• Exactly on the bow roller centreline, rotation axis perpendicular to it, so the rode stows evenly; the rode must feed onto the full drum width without fouling roller side plates or deck opening.
• Check gearbox rotation; it can run in reverse but maximum holding load drops to 1500kg (from 2000kg).
• Flat deck (plinth if needed) of adequate strength; bow roller with a central groove for the chain size.
• Use the deck mounting template (check the printout is correctly scaled), check under-deck clearances, seal hole edges with epoxy on GRP or wood, tighten nuts progressively and evenly – no power tools.
• Mainshaft-to-gearbox interface is anti-seized at the factory: re-apply if the shaft is removed.

Motor/Gearbox Angle

1. Remove circlip and key; slide the gearbox off the shaft.
2. With the gearbox flat (output shaft vertical) remove the 4 × M6 cap screws securing the leg support – careful not to spill oil.
3. Separate just enough to break the seal and rotate to the new position: 18 possible positions in 15° increments; keep the input gear at least partly in oil.
4. Loctite the 4 × M6 screws, torque to 7Nm and refit to the drum.

Normal Use

• Engage the breaker, toggle down to pay out – keep load on the rode so the drum cannot overrun and tangle; disengage the breaker once set.
• Toggle up to retrieve while motoring up to the anchor; bring the last meter (3') in slowly. Never pull the boat to the anchor or break out a fouled anchor with the winch.
• Don't use the winch as the mooring point overnight, and don't rely on it to hold the anchor in the roller – use a tensioner or snubber. Wait for the winch to stop before reversing.
• Rope tail is looped through the eyelet and round the shaft; the eyelet is not for anchoring loads – always keep at least 1 layer of rope on the drum.

Emergency Free Fall

• Temporarily secure the anchor, remove the spring clip at the gearbox end of the shaft and pull the key (the clip helps).
• Spray lubricant into the keyway, stand clear and lower by hand or let it free fall; then tie off to a hard point or refit key and clip.
• Recover by hand, stowing loosely or winding the drum manually.
• Afterwards remove the shaft from the gearbox, clean, inspect and re-apply anti-seize.

Chain Counter Kit P90022 (TASMAN 8)

• Fits an AutoAnchor counter; every model except the AA150 works on drum winches (sensor not included).
• Sensor cable-tied to the support leg; replace the large flat washer at the shaft end with the magnet holder using the longer bolt: bolt, spring washer, magnet holder, composite thrust washer (13mm spanner).
• Counter setup: Rode → Drum Winch, then total rode length and inside/outside diameter.

Counter accuracy is typically within ±10% because of rope stretch and how the rode lays on the drum.

Intermediate Bow Rollers

• Fit between bow and drum winch so the warp stows evenly; sliding roller, hoop keeps the warp on; polished 316 stainless.
• Suitable for 6mm (1/4") to 8mm (5/16") chain and up to 10mm line.
• Optimum roller width = A /(A+B) × drum width. Rule of thumb: A > B use P105094, A < B use P105093. Optimum fleet angle is no more than 4°.
