WARNING: make sure that the power supply to the
electric motor is not switched on when maintenance
operations are carried out.
Quick
®
Bow Thrusters are made in materials that are resist-
ant to the sea environment: In any case, it is indispensable
to periodically remove salt deposits that form on the outer
surfaces to avoid corrosions and consequent system inef-
ficiency.
Dismantle once a year, following the points below:
• Keep the propeller (12 and 13) and the gearleg (10) clean.
• Paint the propeller and the gearleg with anti-vegetative
paint before each season.
WARNING
: do not paint the zinc anode (15), the seal-
ings and the propeller shaft Be careful not to allow
paint to penetrate in the “tracks” of the gearleg (10)
in which the propeller hub moves.
• Check the zinc anode (15) frequently.
• Replace the zinc anode before every season or when it is
more than half consumed.
• After any maintenance, make sure that the bolts (18) that
lock the flange (7) to the gearleg (10) are well tightened.
• After every maintenance, make sure that the propeller (12
and 13) is well tightened and that the bolts (1) locking the
electric motor (3) are tight.
• Make sure that all electrical connections are clean and
firmly fixed (28 and 29).
• Make sure that the batteries are in good condition.
