Ventilation System
10.2 Windshield/Helm Ventilation
The windshield can be lowered to provide ventila-
tion at the helm and improved visibility. The wind-
shield is raised and lowered by hydraulic cylinders
activated by an electric hydraulic pump in the aft
systems compartment bilge. The system is con-
trolled by the WINDSHIELD UP/DOWN switches in
the helm switch panel and touch screen display.
To lower the windshield, press and hold the
Windshield Down switch until the windshield is
lowered to the desired position, then release the
switch. To close the windshield, press and hold
the Windshield Up switch until the windshield is
completely closed. Always release the switch im-
mediately when windshield reaches the full down
or full up position.
A limit switch in the slide track prevents the wind-
shield wiper from operating while the windshield
is lowered. Always make sure the windshield is
in the full up position before attempting to use
the wiper.
