Storage – Mast Down
In areas where it freezes, do not store the system where water can accumulate in the foils. When the water freezes it
will rupture the aluminum. Store the foils under cover, with grooves facing down or on an angle so water will run out.
■
Storage or Transporting
Do not store or transport the system with the lower unit extending beyond the mast. Remove the masthead clevis pin
and shift the furler up so the lower unit can be strapped securely to the mast. Some people remove the drum assem-
bly and halyard swivel for storage and transport.
■
After Storage or Transport
After storing or transporting the unit, clean thoroughly including ball bearings. See instructions on next below.
■
Cleaning and Lubricating
Keep the unit clean. When you wash the boat, flush the
unit with soap and fresh water. Occasionally lower the
sail and flush the halyard swivel with soap and fresh
water.
At least twice a year the unit should be cleaned more
thoroughly by opening the torque tube and flushing the
bearings with soap and fresh water. After the unit has
dried, apply a dry spray lubricant such as McLube®.
Foils may be cleaned by washing with soap and water. A
scrap of luff tape may be run up the foil to scrub inside
the grooves. Foils may be sprayed with McLube® to
reduce friction during sail changes.
■
Inspection
Inspect the unit for signs of chafe, wear or damage.
Inspect the locking devices below the drum and inside
the torque tube for signs of loosening. Check headstay
tension for signs of loosening.
Inspect the swage fitting and lower toggle for signs of
stress corrosion.
Inspect the Norseman or Sta-Lok terminal or rod termi-
nal for signs of loosening.
Inspect all screws on the unit to be sure they have not
loosened.
Inspect the foil to make sure that it has not dropped into
the torque tube. Periodically inspect wire for signs of
wear or unraveling.
