6 MKIV Hydraulic Unit 3
Preassembly Rigging Parts Check/Tools/Adhesive
Tools You Will Need
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.
3. Headstay may require cutting and shortening to fit Harken toggle. Some
headstays may remain uncut by replacing lower stud of turnbuckle with
stud/eye thus eliminating extra toggle.
