MAIN BRUSH LIFT LEVER
The main brush lift lever controls the height of the
main brush.
Pulling the lever back and to the left lowers the main
brush. The main brush may be operated in two
positions --- “normal” and “free---float.” “Normal”
position is used for most sweeping conditions.
Operating in the “normal” position will result in much
longer main brush life. “Free---float” position is used
when extremely uneven areas are encountered. The
“free---float” position allows the main brush to follow
the uneven surfaces more closely.
Pulling the lever back and to the right into the “raise”
position raises the main brush off the floor.
NOTE: Always place the main brush lever in the
“raise” position when the machine is to sit
unoperated for a period of time to prevent the main
brush from taking a set.
NOTE: The power lift lever will not interfere with the
main brush lift lever when it is used to raise a
sweeping brush. The main brush lift lever will not
lower the brush if the power lift lever is in the “up” or
“hold” positions; or if the main brush pressure knob
is in the “fully decreased” position.
OPERATING LAMPS SWITCH
The operating lamps switch controls the headlamps,
taillamps, and the brush spot lamp. Flip the switch
toggle upward to turn the lamps on. Flip the switch
toggle down to turn the lamps off.
HAZARD LAMP SWITCH
The hazard lamp switch controls the rotating or
flashing light. Flip the switch toggle up to turn the
lamp on. Flip the switch toggle down to turn the
lamp off.
TURN SIGNAL LEVER
The turn signal lever controls the turn signal lights.
Pushing the lever forward signals a turn to the right.
Pulling the lever back signals a turn to the left.
CLOGGED DUST FILTER INDICATOR
The clogged dust filter indicator lights when the dust
filters become clogged and excessively restrict
vacuum air flow. Lower the hopper, shut off the main
brush and vacuum fan, and push the dust filter
shaker pushbutton switch to shake the dust filter.
Shake the dust filters when necessary to remove the
air restriction. It may be necessary to clean or
replace the dust filters to remove the air restriction.
Do not continue to sweep with the clogged dust filter
indicating lamp lighted as dust pickup will be
reduced.
DUST FILTER SHAKER PUSHBUTTON SWITCH
The dust filter shaker pushbutton switch operates the
shaker motors which are mounted on top of the
hopper dust filters.
To operate the shaker motors, the hopper must be in
the operating position. Then place the main brush
and hopper lift control lever and side brush control
levers in the “off” position. Push the pushbutton
switch in to shake the dust filters. The filter shakers
will operate for 30 seconds and shut off
automatically.
DUMP DOOR INDICATOR
The dump door indicator lights when the hopper
dump door is not fully open. The dump door should
be fully open and the indicator off whenever debris is
being picked up. It should be closed when raising
the hopper to dump the debris.
Do not sweep with the dump door indicator lighted.
FUEL LEVEL GAUGE
The fuel level gauge indicates how much fuel is left in
the fuel tank.
ENGINE COOLANT TEMPERATURE GAUGE
The engine coolant temperature gauge registers the
engine coolant temperature. Normal engine coolant
temperatures range up to 200
_
F (93
_
C).
Temperatures above this level indicate an
over---heating engine. This condition may arise due
to a low coolant level, a clogged radiator, a loose fan
belt, a defective thermostat, or other engine
malfunctions. Engine overheating will always cause a
coolant loss. If coolant loss does not occur, check for
malfunction of the temperature sending unit.
