ENGINE OIL PRESSURE GAUGE
This gauge registers the engine oil pressure. Normal
engine oil pressure ranges from 7 psi
(50 kPa) at idle, to 35 psi (240 kPa) at full engine
throttle. If the gauge registers an oil pressure reading
below 7 psi (48 kPa), stop the engine immediately
and determine the cause. Failure to stop the engine
will result in severe engine damage.
STEERING WHEEL
The automotive---type steering wheel operates a
steering gear assembly which controls the rear
caster wheel through an arm and tie rod
arrangement. The machine is very responsive to the
movement of the steering wheel. The operator
should use care until he or she becomes more
experienced in guiding the machine.
BRUSH PRESSURE INDICATOR
The brush pressure indicator light stays on when
there is excessive brush down pressure. Under
normal main brush conditions, the light should not
come on. Under wire brush conditions, the light
should flash on and off. When the indicator light
stays on, pull back on the main brush lift lever to get
the wire brush over high spots on the floor. If the light
stays on, reduce brush down pressure by turning the
main brush pressure knob clockwise. Watch the
hydraulic pressure gauge.
BATTERY CONDITION GAUGE
The battery condition gauge indicates the present
voltage potential of the battery. Normal battery
voltage is 10 to 14 volts. If the battery voltage
exceeds 14 volts, it may be overcharging. If the
battery voltage falls below 10 volts, it may not be
accepting or getting a charge from the alternator.
Overcharging and undercharging are indications that
one or more electrical components is in need of
repair.
ENGINE HOUR METER
The hour meter records the number of hours the
machine has been operated. This information is
useful in determining when to service the machine.
SIDE BRUSH SWITCH
The side brush switch operates an electric actuator
which controls the side brush position. Placing the
switch toggle up in the “up” position, raises the side
brush. Placing the switch toggle down in the “down”
position, lowers the side brush.
DIESEL PRE--HEAT INDICATOR
The diesel pre---heat indicator lights when the diesel
pre---heater is in operation.
IGNITION SWITCH
The key---operated ignition switch has four positions.
These positions are: “accessories,” “off,” “on,” and
“start.”
To start the engine, turn the key clockwise to the
“on” position. The diesel pre---heat indicating lamp
may light. Wait until the lamp goes off and then turn
the key fully clockwise to the “start” position to start
the engine. Release the key as soon as the engine
starts and the key will place itself in the “on” position.
NOTE: The diesel pre---heater stops when the
ignition key is advanced past the “on” position. To
reactivate the diesel pre---heater, the key must be
turned back to the “off” position to reset the pre---heat
solenoid.
NOTE: Do not engage the starter for more than ten
seconds at a time, or after the engine has started, as
the starter may be damaged.
PARKING BRAKE
The parking brake controls two brake cables which
are connected to the mechanical drum brakes on the
two front wheels. Pulling the brake handle up
engages the parking brake.
Pushing the brake handle to the left and down
releases the parking brake. Always engage the
parking brake before leaving the machine
unattended and before working on the machine.
