Passenger Windows
Split sash windows in the Blue Bird VISION operate similar to other
windows familiar to school bus drivers. To lower a window, place an
index finger in both of the spring loaded sliding latches and slide
them inward away from the frame. Hold them inward as you slide the
window sash downward.
There are four intermediate opening positions between fully
closed and fully opened. When the sash is opened to the desired
height, release the latch slides and then push the top of the sash
frame upward or downward to make sure the latches on both sides
engage one of the position notches. When the window is in one of
the intermediate positions, the sash can be pushed upward to close
without first retracting the latches. However, the notches of the ful-
ly-opened positions are designed to latch more securely. To close a
window that is fully open, slide the latches inward and then slide the
sash.
The windows are designed for maintenance free operation.
However, a light silicone spray lube may be applied to the slides and
frames as needed to help ensure smooth operation.
