MANUAL RAISE & LOWER OF THRUSTER
If the Thruster cannot be raise or lowered using Electrical or Hydraulic power, it is
possible to raise or lower the unit mechanically.
1) Remove the 2 x M6 leadscrew locking bolts from the base plate using
a 5 mm allen key.
These can be found where the leadscrew enters the base plate.
2) Place a suitable spanner or socket drive ( 1/2" ) onto the top of the
leadscrew.
3) Turn the leadscrew clockwise to raise and anti clockwise to lower,
taking care not to damage the limit switches at the top and bottom of
the stroke.
4) Replace the 2 x M6 leadscrew locking bolts before Electric or
Hydraulic power is reapplied.
