Harken 7413.10 MKIV Jib Reefing & Furling built after Feb. 2009 - Manual (Page 36)

Replace Line
Use 11 mm ( 7 /
16
") diameter line. Use double-braid polyester
line with good wear characteristics.
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.
After Storage or Transport
After storing or transporting unit, clean thoroughly including 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 loosen-
ing 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.
At least twice a year unit should be cleaned more thoroughly
by removing line (first note direction of spool) and flushing
bearings with soap and fresh water. After unit has dried,
apply a dry spray lubricant such as McLube.
Foils can be cleaned by washing with soap and water. A
scrap of luff tape may be run up foil to scrub inside grooves.
If lubrication is required, spray a thin coat of McLube ®
SailKote TM dry lubricant on sail luff tapes away from boat deck.
