10.11.2 Raising the transducer manually
1. Open the lid on the hull control unit and turn off the motor breaker on the hull
control unit. Confirm that the light on the power supply indicator is off. (See
the illustration on the previous page for location of motor breaker and power
supply indicator.)
2. Referring to (a) in the illustration below, unscrew two screws to remove the
cover.
3. Attach the crank to the motor shaft, referring to (a) in the illustration below.
4. While holding the crank, pull the lever toward you and upward to release the
brake as in (b) in the illustration below.
Note:
Hold the crank when releasing the brake, to prevent the transducer
from falling out.
5. Turn the handle clockwise to raise the transducer as in (c) below. (Also, you
can raise the transducer with a socket wrench or impact wrench, using the
socket near the crank. If an impact wrench is used the torque should be
14.5Nm (1.48kgfm).)
6. After retracting the transducer into the tank, set the lever to the holder as in
(d) below.
