Maintenance Clean/Inspect/Storage
Clean
Keep unit clean. When you wash boat, flush unit with soap and fresh water.
Occasionally lower sail and flush halyard swivel with soap and fresh water.
Clean unit more thoroughly at least twice a year. First remove line (note
direction on spool) and flush bearings with soap and fresh water.
Clean foils with soap and water. Run scrap of luff tape up foil groove to clean.
WARNING! Parts can wear, loosen, or corrode and can break at
load. Periodically inspect items listed below and any others as
necessary. See www.harken.com/manuals General Warnings for
additional safety information.
Inspect
1) Unit for signs of chafe, wear, or damage.
2) Screws on unit for signs of loosening or missing:
Foil Screws – Unroll sail to inspect.
Feeder Screws – Unroll sail to inspect.
Adjuster Tube Clamp Screws
Collar Screws
3) Foils to make sure they have not dropped into
drum assembly.
4) Wire for signs of wear, unraveling, or loosening.
5) Locknuts on leg kit for signs of loosening or missing.
6) Lower toggle for signs of wear, cracks, or corrosion.
7) Cotter pin at lower toggle to be sure it is securely
splayed as shown.
Storage – Mast Down
In areas where it freezes, do not store system where water can
accumulate in foils. When water freezes it will rupture aluminum.
Store foils under cover, with grooves facing down or on an angle
so water will run out.
Storage/Transporting
Do not store or transport system with drum assembly extending beyond mast.
Remove masthead clevis pin and shift furler up so drum assembly can be strapped
securely to mast. Some people remove drum assembly and halyard swivel for storage and transport.
