Harken 7413.15 MKIV Hydraulic Jib Reefing & Furling - Manual (Page 33)

MKIV Hydraulic Unit 3 33
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 lower unit extending beyond mast. Remove lower unit and halyard swivel for
storage and transport.
After Storage or Transport
After storing or transporting unit, clean thoroughly including tack and halyard swivel ball bearings. See instructions
above.
Loosen Foil Clamp Before Slacking Backstay
In order to prevent foils from locking against upper stay terminal when backstay is released, loosen foil clamp screws and
lower foil before loosening backstay.
Clean and Lubricate
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.
Foils may be cleaned by washing with soap and water.
A scrap of luff tape may be run up foil to scrub inside
grooves. Sail luff tapes may be sprayed with McLube ®
to reduce friction during sail changes.
Spray sails off boat so Mclube
® spray does not contact deck.
Maintenance Clean and Lubricate/Inspect/Storage
Inspect
Inspect unit for signs of chafe, wear or damage.
Inspect clevis and cotter pins below and inside lower unit for
signs of loosening. Check headstay tension for signs of loosening.
Inspect swage fitting and lower toggle for signs of stress
corrosion.
Inspect Norseman or Sta-Lok terminal or rod terminal for
signs of loosening.
Inspect all screws on unit to be sure they have not loosened.
Inspect foil to make sure that it has not dropped into lower unit.
Periodically inspect wire for signs of wear or unraveling.
WARNING! Worn, damaged or corroded parts may
break suddenly. Periodically inspect items listed
below and any others as necessary.
WARNING! Decks sprayed with McLube ® will
be very slippery which can lead to slipping and
falling overboard. Spray sails off boat so
Mclube ® spray does not contact deck.
