Safety Precautions/Parts Description
Introduction
This manual gives technical information on installation and service. The information is destined exclusively for specialized personnel or expert users. Installation, disassembling, and reassembling by personnel who are not experts may cause serious damage to property, injury to users, and injury to those in the vicinity of the product. If you do not understand an instruction, contact Harken.
The user must have appropriate training in order to use this product.
Harken accepts no responsibility for damage or harm caused by not observing the safety requirements and instructions in this manual. See Limited Warranty, General Warnings and Instructions at www.harken.com/manuals.
Purpose
Harken Jib Reefing and Furling systems are designed for rolling sails on sailboats to reduce sail size or to completely roll so wind has little effect on the sail. Use of this product for other than normal sailboat applications is not covered by the limited warranty.

Size Check
1. Check headstay and clevis pin dimensions in chart below.
WARNING! Do not drill boat's chainplate or toggle. This may result in rig failure. Use the correct size toggle and clevis pin.
2. Harken does not recommend drilling boat’s chainplate or toggle. Bushings may be required to fit boats with smaller clevis pin sizes.
3. Will drum fit on bow? See page 7. If necessary, use an additional toggle to slightly raise unit. To clear anchor use a Harken long link plate which can be cut to various lengths.

Preassembly Line/Rigging Parts Check/Tools
Line Diameter/Length
Furling line is not included with furling unit. Purchase 12 mm (7/16") low - stretch Dacron double - braid line. Line length should be equal to the length of the boat, plus the length of the foot of the largest genoa, plus 2 m (6').
Line not included.
Toggles
1. Harken toggle assembly required. Sold separately.
2. Mating turnbuckle components, with eye at lower end, must be purchased separately. See page 8.
3. Headstay might require cutting and shortening to fit Harken toggle. Some headstays may remain uncut by replacing lower stud of turnbuckle with stud/eye, eliminating extra toggle.
4. Rod rigging requires Harken rod adapter stud.
WARNING! A stay that is old or damaged can break suddenly, causing an accident. Headstay condition should be checked by a professional rigger before reusing.

MKIV furlers are shipped with 3M 5200 adhesive. Use adhesives on dry connectors and foils. Use 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 100 F (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 are fitted.
Note: A small amount of adhesive may bulge out of injection ports. If possible let system sit for several 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.
Preassembly Dimensions/Sailmaker's Instructions
Luff Length
Note offsets above and below sail.
A shorter luff may be required if a halyard restrainer is necessary (page 31) or a toggle or long toggle assembly is used to raise the drum.
If luff of sail is not long enough to put halyard swivel near top of headstay foil,
B
A
a pendant must be added. See page 29.
Tack Setback
Note setback for tack shackle and cut sail accordingly.
Luff Tape Size -6 (5 mm or 6/32")
J - Finished luff tape size: 5.5 mm (0.215") K - Luff rope size: 4.8 mm (6/32", 3/16") L - Max Ø in sail groove: 6.5 mm (0.26") M - Gap in sail groove: 2.4 mm (0.096")

L
Luff Tape Length
M
Cut off top of luff tape so it is 450 to 600 mm (18" to 24") below head of sail. This allows head to lag behind rest of sail to help flatten it. It will also help the head to roll more smoothly.
C
Note feeder height and extend bottom of luff tape downward so it is below feeder. This will prevent luff tape from catching in feeder as sail is lowered.
Tack and Head Shackles (Unit 3 Only)
Make sure tack and head shackles fit sail rings. Minimum inside dimensions of

2. Open end of wire and install Norseman or STA-LOK
3. Rod adapter nosepiece for Harken rod adapter stud: Threaded nosepiece must have a positive lock as well as adhesive. Use Harken stud with cotter pins. See page 22.
WARNING! Using a threaded nosepiece with only adhesive at the upper rod eye terminal may result in headstay system failure. Make sure there is a mechanical lock.

Under 38 mm (1 1/2") Eliminate top foil and run foil higher in drum assembly.
Preassembly Confirm Foil Length
Confirm foil length by laying foils alongside stay with turnbuckle components.
Pull stay out so it is straight. Attach Harken toggle to bottom of stay. Make sure toggle straps are straight. Adjust turnbuckle so that length of stay with Harken toggle will fit boat. Turnbuckle should be one-half to two-thirds open to allow for rig adjustment.
Line up drum assembly so holes below drum line up with holes in Harken toggle. Make sure toggle is tensioned when measuring.
Line up bottom foil so foil clamp is centered or just below center of notches in bottom foil.
Note: Position top foil so that including top cap, the foil will ride 25 mm (1") below terminal. If wire fitting at top of stay is swage, foil must ride just below shoulder of swage. Mark cut line on foil. Wrap tape around foil as a guide so cut is straight.

If 7304 halyard deflector is
used, add 25 mm (1").

Assembly Top Foil
Cut foil to length using hacksaw.
Deburr inside edge using rat-tail file.
Prepare top foil for drilling.
Tip: Mark top foil to distinguish from cut-off piece.
Scribe line on top of foil to mark drill holes. Lay top foil alongside cut-off piece and use a flat metal object (i.e. metal ruler) to scribe top line of foil.
