6.1 Inspection
6.2 Service
To ensure that the system rotates easily and functions satisfactorily year after year, regular inspection and
maintenance should be carried out. This should be done once a year. Maintenance is simple, even with the
Furlex rigged on the boat.
Inspection points:
• Check for damages on the luff extrusion. If the sail grooves are damaged this may cause damage to the sail.
• Check that all rotating parts turn freely and that all bearings are greased. Lubricate with water resistant
Furlex grease if bearings seem dry.
•
Halyard leads should be inspected once a year and any sharp edges smoothed with a file. A halyard lead
should be replaced when wear exceeds 50%.
The Furlex-system is preferably stored with the mast
when the mast is down. Make sure that no aluminium
surfaces are in contact with steel parts.
The drum unit and the halyard swivel can easily be
removed from the system, see ”Dismantling”. This will
make it easier to tie the foil to the mast.
Under no circumstances should an unwashed or damp
Furlex system be wrapped in plastic or any other
impervious material.
In areas where frost can occur, the Furlex should be
stored in a dry place or with its centre extrusions raised.
This is to avoid ice damage to luff extrusions at sub-
zero temperatures.
6 Maintenance
Fig. 6.3.a
Wash and rinse the entire Furlex-system with fresh water and a mild detergent to remove dirt and salt.
Note! Some detergents contain substances which can cause aluminium to corrode, so it is important to rinse
all detergent off thoroughly.
When the parts have dried, the anodized surfaces of the luff extrusions can be treated with a silicon free boat
polish or wax. This offers good protection and prevents particles of dirt from adhering and then soiling the sail.
The stainless steel components can be treated with a suitable polish. Always protect black plastic when
polishing stainless compontents
Lubricating points:
•
Remove the brims and lubricate all four ball bearings in the lower
unit with water resistant grease.
Main upper bearing.
Lower main bearing.
Tack ring bearings.
• Bring the halyard swivel down to the sail feeder and lubricate
both ball bearings
with water resistant grease.
