Commissioning - Harken UNIT 2 MKIII Instruction Manual

Commissioning

The furling line is attached to the drum and led to the cockpit in five steps.
Use Harken bullet blocks for the forward and intermediate lead blocks. Use a 019 little Hexaratchet
for the aft-most lead block. Harken part 267 is a lead block kit with three 168 bullet blocks; four 061 stanchion mount
bases; one 019 ratchet block; and a 4" (100 mm) cleat. Use the lead block kit or the best blocks for your needs.
Pass line through enclosed window.
Tirer la drosse à travers la fenêtre du guide anti usure.
Leine neu durch Fenster fädel.
Passare la cima in una delle due aperture della guida.
Tip: The position of the suncover on the sail determines the direction of rotation: Suncover to starboard - "charge" by turning clockwise. Suncover to
port - "charge" by turning counter-clockwise. Keep tension on the line while "charging".
2
Loosen the line guard assembly screws and align the opening in the basket so the furling line leads properly at all
times. The angle at which the line exits the basket changes as the amount of line on the drum changes. Check for
chafe with varying amounts of line on the drum before locking the unit.
Tip: When line is "charged" by turning drum counter-clockwise, the opening will look "off center" to starboard and vice versa.
061 stanchion mount bases provide
an ideal attachment method for
furling line lead blocks. The ball
joint socket accepts most small
boat swivel blocks, including
ratchet blocks.

The furling line lead changes as the
amount of furling line on the drum
changes.

Furling line must enter drum at

bour perpendiculairement à l'étai.

La cima di avvolgimento deve

con lo strallo l'angolo giusto.
C Intermediate lead blocks hold the line near the gun-
wale. The number and placement of these leads depends
on your boat length and configuration.
B Position of forward lead block
(Harken 125 or 168) is critical
as a proper lead prevents line chafe.
The furling line may be led down either side of the boat.
3
Position the forward block so that the line enters the drum at right
angles to the headstay and is centered vertically in the opening.
Move the block fore or aft to adjust the line vertically in the opening.
Improper positioning will result in chafe or cause line to wrap
unevenly on the drum. In many cases, proper placement cannot be
achieved by using a stanchion mount lead base and the forward lead
block must be attached to a padeye mounted on the deck.
4
Mount a 019 little Hexaratchet (or other configuration of ratchet
block) as the after lead block to insure proper drag on the furling
line to prevent line overrides in the drum.
Tip: Position the ratchet block so the line turns at least 90°.
Position a standard horn cleat in a convenient location in the cockpit.
5
Lead the line through the forward and after lead blocks. The after
block should be a little Hexaratchet. If the line has been led cor-
rectly you should hear a clicking sound. Then, position the intermedi-
ate blocks to keep the line clear of the side decks to insure a fair lead.
D Aft-most lead block must be a Harken little Hexaratchet to provide the proper
line drag while furling. This block should be placed to lead the line to a cleat in
the cockpit. If the line has been led correctly you should hear clicking when you
pull the line. If not, the ratchet switch may not be engaged or you must relead
the line through the block in the opposite direction.

Leading the Furling Line to the Cockpit
1
Pass the rope through the hole in the hub
of the drum and use a screwdriver or
pliers to pull the line out the bottom. Tie a
small overhand knot and pull it up under the
drum assembly. To prevent binding, make
the knot as small as possible and push the
knot securely up into the drum assembly.
"Charge" the system by turning the foils
to wrap line on the drum.
