Maintenance
Cleaning
Clean the sensor with a soft cloth and mild household detergent. If fouling
occurs, use a stiff brush or putty knife to remove the growth being careful to avoid
making scratches on the transducer’s face. In severe cases, wet sand the surface
with fine grade wet/dry paper.
If the paddlewheel becomes fouled or inoperable, it can be removed for
cleaning. Remove the two screws from the paddlewheel assembly. Lift the
assembly to remove it from the transducer. Grasp the two retaining bars and pull
to access the shaft.
After cleaning, slide the paddlewheel onto the shaft and fit the shaft into the
two retaining bars. Slide the assembly into the paddlewheel housing being sure
the flat side of the paddlewheel blade matches the side view below. Screw the
assembly in place (see Figure 3-10).
