Preparation before installing the hull unit on the retraction
tank
An anti-vibration guide is attached to the FSV-75 hull unit shaft. The rollers on the
guide can prevent the hull unit from being installed into the retraction tank. For this rea-
son, the rollers must be pushed inwards BEFORE installing the hull unit into the re-
traction tank.
Note: The following procedure is also required when you remove the hull unit from the
retraction tank.
1. Unfasten the two wing bolts at the top of the hull unit, then rotate the motor cover.
2. Pull the release lever away from the holder.
3. Attach the ratchet wrench, referring to the figure at step 6.
4. Push the release lever up or down to release the motor brake, keeping a firm hold
on the ratchet wrench.
5. With the motor brake released, turn the ratchet counter-clockwise to raise the
shaft (tank guide).
6. While keeping a firm hold on the ratchet wrench, let go of the release lever.
