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.

7. Remove the ratchet wrench and return it to its holder. Restore the motor brake to
its normal position.

stopped and the transducer cannot be raised or lowered.
