Ensure that you know the location and how to operate the main battery switch and that disonnects the thruster from all power sources
(batteries) so that the thruster can be turned off in case of a malfunction.
Always turn the main power switch off before touching any part of the thruster, as an incidental start while touching moving parts can
cause serious injuries.
Always turn the control device off when the thruster is not in use.
The maximum continous usage time of the electrical thruster is approximately 3 minutes. The electromotor has a built in thermal cut-off
switch that will shut off the electromotor if it is overheating and re-engage it when it has cooled down some. This should be considered
when planning your manouvering.
This also means that the thruster will limit its total running time per time period so that you can not count on the thruster to hold you
in a current and sidewind for extensive time periods. Depending on the ambient temperatures etc. the thruster will be able to run ap-
proximately 10 % of the time.
Never use a thruster close to somebody in the water, as the thruster will draw objects close by into the tunnel and contact with the
rotating propellers will cause serious injuries.
With the boat on land, only run the thruster for a fraction of a second, as without resistance it will accelerate very fast to a damaging
rpm. Also, while the thruster is in air, make sure that the propellers have come to a complete stop before performing a direction change
of the thruster, as it might cause damage to the thruster.
If the thruster stops giving thrust while the electromotor is running, chances are that there is a problem in the drive-system. You must
then immediately stop trying to run it, and turn it off, as running the electromotor for more than a few seconds without resistance from
the propeller, can cause serious damage to the electromotor.
When leaving the boat always turn off the main power switch for the thruster.
We advice to always keep the main engine(s) running while using a thruster. This will keep the batteries in a good charge condition.
This will also give better performance to the thruster, as a higher voltage at the thruster results in a higher torque (power) in the elec-
tromotor.
Please note that the performance of a thruster strongly depends on the voltage available at the electromotor. This voltage will decrease
by time because aging batteries have a reduction of capacity. By installing new batteries the effect of the thruster should be back at
the original level.
Make sure that only one control is used at the same time, if two panels are operated in opposite directions at the same time the thruster
will not run at all. If they are operated in the same direction the thruster will run in this direction.
If the thruster is not performing or functioning as usual, the cause for this must be found and corrected as soon as possible so to
avoid causing any other or further dammage to the equipment. You must also turn off the main battery switch immediately in case the
problem is of electric origin.
To activate the docking control panel, push the two “ON” buttons simultaneously.
The docking control panel shuts of automatically approx. 25 minutes after it was energized. To use the docking control panel later, push
the two “ON” buttons simultaneously.
The boat switch is an on/off switch device only that controls your thruster(s). The thruster(s) will run at a constant speed regardless of
how hard you pull/push the control switch.
Warning
:
Tampering with the Ignition Protected stern thruster assembly or any attempt to disassemble anything on this thruster ass-
mebly inside the boat can cause an explosion with very serious consequences.
If there is a problem with your Ignition Protected stern thruster, please contact your dealer.
Danger: NEVER Disassemble any part of the Ignition Protected stern thruster assembly
