MAINTENANCE OF THE RETRACT
Regular checks
Lower and raise several times every month
Hydraulic power oil reservoir level.
Hydraulic hoses for chaffing and leaks.
Control panels, like all external equipment, should be protected from the sun and
weather. Clean with a soft cloth and mild detergent solution.
Yearly checks boat ashore
Clean the turbine, gearbox and the propellers with a sponge and detergent soap. It is
also advisable to remove the top cover plate and clean the interior of the caisson and
rinse well the articulated joints.
IMPORTANT If the vessel will remain out of the water for some time, for example
dry storage for the winter, the top cover plate must be removed and the RETRACT
mechanism must be thoroughly rinsed with fresh water, especially the articulated
joints. Do not operate below 0° C.
1.
Replace all anodes.
2.
Remove the propellers and check oil seals.
3.
Inspect and repair the hull closing plate gasket for deterioration or missing
pieces.
Check and tighten if necessary, the plate fixation bolts.
4.
apply antifouling paint to the closing plate on the outside, on the edges and if
desired to the plates inner surface. If you find growth on the unit, this is
because your closing plate gasket allows light to enter the enclosure.
CAUTION
Do not use antifouling or other copper based paints on the
RETRACT unit.

The transmission oil must be changed each year. This can be done by
extracting the sump plug screw. Never let the oil level in the lube tank descend
below the level of the ships waterline.
