Manual Operation
Before using the system, make sure that the emergency
handle can rotate and not hit the bow pulpit.
Cordless drill adapters work well, but there must be a
fully-charged cordless drill on hand at all times. Because
a cordless drill may lose power, always have an
emergency handle onboard.
1. Disconnect power.
2. Communicate to all crewmembers that you are going
to work on the furler. Tell them to not attempt to
restore power while you are working on the furler.
3. Have an emergency handle available.
4. Using all personal safety precautions including PFD,
harness and tether, go forward.
5. Check to make sure the power is off to the furler.
6. Remove the manual drive socket by unthreading the
cap as shown above.
7. Use the emergency handle or a cordless drill to turn
the foil until the sail is reefed or furled.
8. Inform crewmembers when you are finished.
9. Attempt to restore power to the furler.
WARNING! You must have a reliable manual
drive procedure in place before using the
system. Failure to have a manual drive
procedure can lead to an accident. See www.
harken.com/manuals for additional safety
information.
WARNING! You must observe all personal
safety precautions including using a harness
and secure tether and personal flotation device
(PFD) when going forward to bow. Failure to
have a tether system and PFD can result in
falling overboard and death.
