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

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.
Gasoline powered machine: 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 use leaded fuels. The use of
leaded fuels will cause permanent damage to the
system’s oxygen sensor and the catalytic
converter.
LPG powered machine: When the tank is full,
none of the segments are lit. The last two
segments will flash when the tank is low on fuel or
empty.
