Harken recommend an annual pre-season service as a minimum and a second mid-season maintenance check for any yacht based in sea water.
Harken advise frequent flushing with fresh water, driving out dirt and salt-water to preserve smooth operation.

Maintenance is required immediately if:
Ratcheting seems sluggish or sticky: Pawls may have been greased instead of oiled. Clean any grease off and then oil the pawls.
Winch doesn’t turn freely: Refer to winch manual and clean, grease, and oil winch. Check for damaged springs, pawls, or bearings to make sure nothing else is wrong.
Winch can be turned in both directions: Problem with the pawls. May be stuck in grease or damaged.
Inspect Carefully for:
- Signs of damage, wear or corrosion on pawls and springs, bearings, gears, and spindles. Replace immediately.
- Loose or missing deck mounting fasteners.
