MAINTENANCE
12.1
Hull
Check for damage or cracks in the hull.
For thorough cleaning use a hot pressured water-cleaner having approx. 80 bar pressure.
12.2
Electrical system
Check condition of electric wiring connections.
12.3
Motor
Check the overall condition of the motor, especially the motor shaft, which must rotate freely and without significant
mechanical friction.
12.4
Sacrificial anode
The condition of the anode can be simply checked by visual inspection or alternatively by weighing it and comparing its
weight with a new one. If its weight is reduced by 50% it is time to change the anode.
12.5
Batteries
REPLACEMENT
Follow safety precautions carefully and always wear safety goggles.
•
Before removing the battery to be changed, always mark the position of the positive (+) and negative cables so that
these can be correctly positioned when installing the new battery.
•
Always disconnect the negative cable first. Always reconnect the negative cable last. This avoids the formation of
dangerous sparks.
•
Then carefully remove the old battery, making sure that there is no leakage of liquid.
•
Thoroughly clean and inspect the battery compartment.
•
Carefully inspect the wiring for any anomalies (breakages, frayed cable, loose terminal board). The cable terminals
(clamps) must be cleaned and replaced if they show signs of corrosion. The electric wiring connections must be
suitably sized and correctly done in order to guarantee full system efficiency.
•
Install the new battery correctly, in the same position as the previous one, or if it's position is changed, check the
installation/wiring diagram.
•
To avoid danger of short-circuit, make sure that the surface of the installed battery does not come into contact with
any top part of the compartment (the poles must not touch surfaces above them).
•
Fix the battery firmly to its compartment to avoid accidental movement.
•
Tighten the terminal/pole connection but without exaggerating. The connection must be tight but not forced.
•
Finally spray anti-corrosion protection on the pole and terminal.
