■ INSTALL HOSES
Use hose end fittings which are:
Drive: JIC 9/16-18 female swivel
Drain: JIC 7/16-20 female swivel
Do not use locking solution or tape on connections.
Alternate Method: Remove furling unit end fittings and
use SAE straight thread O-ring male hose end fittings.
Assembly Install Hoses/Gear Oil Level/Headstay Tension
CAUTION!: Do not overfill gear oil as this will
cause leaking from the breather valve which
may cause damage to your vessel.
Oil can be checked from top of case. Insert a small metal
stick into filler hole at top of gear housing.
Oil should be at bottom of gears. When unit is in angled
sailing position, oil level will be 2" (51 mm) from top
of housing.
■ CHECK GEAR OIL LEVEL
■ ADJUST HEADSTAY TENSION
There is no need to unlock turnbuckle. If sail is up, make
sure halyard is loose.
Do not adjust under sail.
Insert winch handle and rotate counter clockwise to loosen
or clockwise to tighten stay. Total adjustment is 5" (127mm).
CAUTION!: When tightening the stay, if handle
becomes suddenly hard to turn, stop immediately.
Forcing handle when adjuster is completely closed
will damage gears.
All final rig tensioning or spar bending should be done
using a conventional backstay adjuster.
