4.2 Breakage of the engine spindle.
5.1 The chain locker is tangled; therefore, the emergency mechanism
becomes operative.
5.2 The chain is of poor quality with burrs and zinc deposits that do
not allow the free flow of the links; therefore, the emergency
mechanism becomes operative.

5.4 Wear of the emergency mechanism of the spring control.
5.5 The chain stripper interferes with the gypsy: it is possible to
weigh the operation, while to lower, the emergency mechanism
becomes operative.

hubs are in contact and prevent closure.
Possible causes
4.1 (SERVICE) Uninstall the winch and replace the broken parts. Check out carefully that pieces or
splinters of broken parts did not enter into the oil circuit and have ruined other mechanical parts. (*)
4.2 (SERVICE) Replacing of the engine. Care must be taken that the broken part did not remain in the
hole of the worm screw. (*)
(*) Take advantage of this opportunity to replace any other worn parts, especially gaskets, screws, tabs,
seeger, and oil.
5.1 Check out that immediately after the anchor there is a joint that allows the chain to unfold properly
when weighed.
5.2 Remove the chain from the locker and inspect it link by link. Intervene with the appropriate tools to
make it as loose as possible and free of obstructions.
5.3 Lower manually all the chain in a sea bed deep enough to enable it to unfold properly. Retrieve it
with the winch.
5.4 A (SERVICE) Uninstall the winch from the boat and disassemble it into its parts by replacing the
spring. Take advantage of this opportunity to replace any other worn parts, gaskets, screws, tabs, seeger,
and oil.
B (SERVICE) It is possible to block the EMERGENCY MECHANISM so that the gears are always
engaged both in UP and in Down. This operation must be authorized by the shipowner. The solution
rules out completely the possibility of carrying out the emergency operation.
5.5 Restore the condition of the chain stripper by repositioning properly in the gypsy centreline. If it is
deformed. It must be replaced.
6.1 To carry out the warping operation the main shaft must run in the same rotation direction of the
winch gypsy when it weighs the chain.
7.1 Check out clutch tightening. If necessary, measure the parts and check out possible deformations. It
is possible to add some thickness to stem the problem. Then replace the damaged parts.
7.2 Replace the clutch and/or the gypsy
