9.12.2 How to raise the transducer manually
1. Open the lid on the raise/lower control box of the hull unit and turn off the motor
breaker. Confirm that the power lamp is off. (See the illustration on the previous
page for the location of those parts.)
2. Unscrew the butterfly bolts, then move the motor shaft cover.
3. Attach the ratchet wrench to the motor shaft.
4. While holding the ratchet wrench, pull the release lever toward you and upward to
release the brake.
Note: Hold the ratchet wrench when releasing the brake, to prevent the transduc-
er from falling.
5. Turn the ratchet wrench counter-clockwise to raise the transducer.
6. After retracting the transducer into the tank, set the release lever to the holder.
7. Remove the ratchet wrench and return it to its holder. Restore the motor brake to
its normal position.
Note: Be sure to return the ratchet wrench to its holder. Otherwise the hull unit will be
stopped and the transducer cannot be raised or lowered.
Before operating the hull unit
manually, check that the motor
brake and shaft are working
properly.
