When deploying, the actuator must be allowed to reach its own internal minimum extension limit switch.If the
tunnel is not sufficiently clear of the hull in the deployed position, you can adjust the vertical position of the
tunnel using an adjustment screw. Slacken the nut (1) on the forward edge of the fitting slightly and tighten the
nyloc nut (2) on the aer edge of the fitting until the water flow through the tunnel is not disturbed by the hull.
Then lock the adjustment by tightening the nut (1) again.

Next, adjust bracket (3) so that the side support bolt (4) is centred on its surface when the thruster is in the fully
deployed position. To do this, loosen the nut holding on the bracket (3), move position and re-tighten nut.

Finally, adjust bolt 4 so that there is a gap between the end of the bolt and the side support bracket of 0.5-1mm.
The bolts on either should not press on to the brackets when the thruster is not running.
