Harken 7410.10 MKIV Jib Reefing & Furling - Manual (Page 24)

Commissioning leading line to Cockpit
24 MKIV Unit 0
Note: As furling line lead changes, make sure line
doesn’t chafe against line guard. Rotate line guard
if necessary.
Drum Empty
(sail furled)
Drum Full
(sail unfurled)
Position 7401 Forward Stanchion Block so line enters
drum at right angles to headstay and centers vertically
in opening. Install so line is inside stanchion.
Correct block position is critical to even line
spooling and ease of furling.
7401 Forward Stanchion Block
Install 7403 Outboard Stanchion Blocks so line is
outside stanchions.
Number and placement of leads depends on boat
length and number/configuration of stanchions.
7403 Outboard Stanchion Blocks
Mount 7402 Ratchet Stanchion Block as furthest-aft
lead to prevent line overrides in drum when unfurling.
Position ratchet block so line turns at least 90°.
Install so line is inside stanchion.
Lead line through block so ratchet makes
clicking sound when pulling line to furl sail.
Tip: Make sure ratchet switch is in “ON” position. If there is
no clicking sound, lead line through block in opposite direction.
Lead line to Furling Line Cleat in cockpit.
7402 Ratchet Stanchion Block
Install so line is angled as shown.
Use #10 (5 mm) fasteners.
HCP168 Furling Line Cleat
Run line through enclosed window in guard and into hole
in bottom plate of spool. Tie a small overhand knot and
pull it up under drum assembly.
Mount lead blocks
Furling line can be led down either side of boat. If boat is in slip, consider mounting opposite dock.
Remove four screws on stanchion blocks. Clamp blocks to stanchions. See instructions below.
Tip: Start all four screws before tightening.
WARNING! Lead line through enclosed window. If
line is led through opening between two enclosed
windows it can ride above lineguard and jam
furler which can cause loss of control of boat.
Note location of sun cover. Charge system by rotating furler to wrap line on drum.
Tip: Sun cover to starboard—turn clockwise to charge. Sun cover to port—turn counter-clockwise.
Tension line while charging.
