CONTROL UNIT CLEANING AND MAINTENANCE
11.8.1 Outer cleaning
To keep all our accessories and their parts in good working order, they
should be cleaned carefully and thoroughly as often as possible.
As the gangway, the swim ladder the linear lift and the garage hatch are
located in a very critical position compared to all the other equipment on
board, being in constant contact with water and acid exhaust fumes, they
require a more accurate cleaning.
For a careful and thorough clearing operation, cover all the steel parts with
a layer of parafn oil. As far as the coated parts are concerned, use a paste/
cream. This will prevent the forming of rust stains, that could give the im-
pression the device is built with materials not suitable for its use.
.
DANGER
During cleaning or maintenance operations, make sure that nobody can
activate the gangway, the swim ladder and the garage hatch, because
they could cause serious injury to people; it is recommended to discon-
nect the power supply.
CAUTION
In order not to jeopardize the gangway of the seals, perform the washing
in the box avoiding that water enters under pressure.
ENVIRONMENT
Do not discharge hydraulic oil in the sea, but in the special areas for toxic
waste disposal.
CAUTION
RIVA declines all liability for any accident to persons or damage to prop-
erty caused by a wrong use of the devices.
CAUTION
After completion of some operations, check the oil level of the tank. The
oil top up in the tank must be performed with the gangway completely
retracted.
MAINTENANCE
Grease all mechanical parts at least once a month.
NOTE
For further information on the maintenance operations envisaged, refer to
the relative manuals of the system manufacturers.
