SCREEN RETENTION SYSTEM

OPERATION

The retention system is operated by inserting the tensioning handle into the receptacle provided
on the positioning gear and pressing the handle downward (Figure 6-2). The downward motion
rotates cams on the keyed shaft that drive the retention pins outward against the screen panel
edges. Rotating the keyed shaft in the opposite direction retracts the retention pins, permitting the
screen panel to relax.
