HYDRAULIC FRONT CURTAIN LIFTER (OPTIONAL)
FUNCTION
The Front Curtain Lift (FCL) Option supplements the existing Sweeper Pressure Bleeder in or
-
der to enhance sweeper performance in light debris removal such as found in curbs with heavy
leaf accumulations or litter-filled parking lots. A single hydraulic cylinder rotates the curtain lift
mechanism raising the front curtain. Once the curtain is raised, light debris can easily pass un
-
der the pickup head and is quickly delivered up into the hopper.
The FCL is controlled by a toggle switch inside of the cab. The FCL should be used to raise the
front curtain only after the Pressure Bleeder has been opened. The minimum pressure bleeder
opening is approximately ¼ to ½ open. Failure to open the pressure bleeder first will cause light
debris to be blown away form the Pick-Up Head by the powerful blast orifice air jet. Once the
light debris has been swept, the FCL is easily retracted to the stowed position releasing the
front curtain for normal operation.
