MAIN BRUSH SHUT DOWN LIGHT
The main brush shut down light
comes on
when there is excessive down pressure for the
main brush, or there is a problem with the main
and side brush hydraulic motor circuit. The brush
pressures can be reduced with the main brush
and side brush pressure knobs.
CLOGGED FILTER LIGHT
The clogged filter light
comes on when the
hopper dust filter is clogged. If the machine is
equipped with a Regenerative Filter System
(RFS) option, the light will remain on for a few
seconds each time the RFS cycles.
To clean the filter, press the filter shaker switch. If
the clogged filter light remains lit, manually clean
the hopper dust filter. See HOPPER DUST
FILTER in MAINTENANCE.
HOPPER DOOR LIGHT (OPTION)
The hopper door light
comes on when the
hopper door is open. Make sure the hopper door
is closed and the hopper door light is off, before
sweeping with the machine.
FUEL LEVEL GAUGE
The fuel level gauge
indicates how much fuel
is in the fuel tank with a segmented LED light.
When the tank is full, all ten of the segments are
lit. As the fuel tank empties, the segments shut
off. The fuel tank is empty when all ten of the
segments have shut off.
NOTE: Do not let the fuel tank empty completely.
Air can enter the fuel system. The fuel system will
need bleeding before the next engine start.
