Preassembly
Rigging Parts Check/Tools/Adhesive
Tools Required
MKIV Furlers are shipped with 3M 5200
adhesive. Use adhesives on dry connectors
and foils using the special injection system
described in the assembly section. Parts
may immediately be exposed to rain. Cure
is best at 70 F (22 C) with 50% humidity.
Do not apply at temperatures below 40 F
(5 C) and above 100F (38 C).
Although adhesive has not cured it will
remain in place on foil joints whether
they are left on the ground or raised up
on boat. Foils can be raised immediately
after assembly and sails fitted.
Note: A small amount of adhesive may
bulge out of injection ports. If possible
let system sit for a couple days before
sailing. If adhesive gets on sails remove
using acetone. For faster-curing adhesive,
purchase 4200 Fast Cure.
Note: Damaged foils can be repaired.
Use a hand-held propane torch to heat
joints until foils can be pulled apart.

Toggle Assembly
1. Harken toggle assembly or hydraulic cylinder required. Sold separately.
2. Mating turnbuckle components with eye at lower end must be purchased separately.
See page 10. Contact Harken for toggle housing dimensions to fit eye fitting.
3. On retrofits, headstay will require cutting and shortening to fit Harken toggle. Unit
is designed to fit over most turnbuckles. Contact Harken for questions on interior
housing for turnbuckle.
4. Rod rigging requires a terminal to allow rod to pass through foils. Generally
this will require a split collet design.
WARNING! A stay that is old or damaged may break suddenly. Always
use a new stay when installing a furler or have condition checked by a
professional rigger before reusing.

two hoses: -6 (3/8" ID). Contact Harken for further hose size recommendations.
Hose End Fittings
Use SAE straight thread O-ring male hose end fittings - 9/16-18. Hydraulic cylinder
