Operation
To open the wiper control housing, unscrew the lid in an anti-
clockwise direction. If the lid is tight, the lid shifting tool supplied with
the Hydro-Wiper can be used. This tool fits into the groove in the top
face of the cap, and allows greater leverage. The lid shifting tool
should never be used to tighten the lid.
Inside the wiper control housing is the battery holder, wipe interval
select switch, power switch, and diagnostic LED.
