When using the bow thruster watch out for swimmers or light
boats which could be in the near vicinity of the bow thruster tun-
nel openings.
Pass on the safety instructions to others using the bow thruster.
This product should only be installed and maintained by
qualified personnel who have read and understood the in-
structions and precautions in this manual. Failure to follow

2 Introduction
These installation instructions give guidelines for fitting the VETUS
bow thruster 'BOW4012' .
The quality of installation will determine how reliably the bow thrust-
er performs. Almost all faults can be traced back to errors or impreci-
sion during installation. It is therefore imperative that the steps given
in the installation instructions are followed in full during the installa-
tion process and checked afterwards.
Alterations made to the bow thruster by the user will void any li-
ability on the part of the manufacturer for any damages that may
result.
The thrust given by the bow thruster will vary from vessel to vessel
depending on the effect of the wind, the water displacement and the
shape of the underwater hull.
The nominal thrust quoted can only be achieved under the most fa-
vourable conditions:
• Make sure that the batteries are supplying the correct voltage dur-
ing use
• The installation is carried out in compliance with the recommen-
dations given in this installation manual, in particular with regard
to:
- Sufficiently large diameter of the battery cables so that voltage
drop is reduced to a minimum.
- The manner in which the tunnel has been connected to the
hull.
- Use of bars in the tunnel openings.
These bars should only be used where this is strictly necessary
(if sailing regularly in severely polluted water.)
- The bars must have been fitted correctly.
Following the above recommendations will result in longer life and
better performance of your bow thruster.
• For maintenance, please consult the 'Maintenance and Warranty
Book' supplied.
• Never allow the bow thruster to operate for a long period; the
maximum length of usage is restricted because of heat release in
the electric motor. After use the motor must be allowed to cool off.
The maximum continuous length of usage and the thrust as
specified in the technical details are based on the recommend-
ed battery capacities and battery cables.
If significantly larger batteries in combination with very short
battery cables of significantly larger diameter than recom-
mended are used then the thrust will increase. In such cases
the maximum length of usage must be reduced in order to
prevent damage to the motor.
