CHECK ENGINE (WARNING LIGHT OPTION)
This engine has a low oil pressure and high water temperature shutdown. If the engine oil pressure srops too low
or the water temperature goes too high, the engine will shut down. Add engine oil until the oil is brought up to the
correct level, or wait for engine to cool down, then check coolant level.
WATER TEMPERATURE GAUGE
The Water Temperature Gauge is located on the console panel above the steering wheel in the gauge cluster. The
gauge is mechanical and activated by a sender in the engine. It displays the engine coolant temperature in
fahrenheit.
HOUR METER
The Hour Meter is located on the console panel above the steering wheel in the gauge cluster. This meter is
activated when the key switch is in the “ignition” position. The meter indicates actual “run” time of the machine.
The meter is used to indicate when maintenance should be done to the machine.
FUEL GAUGE/LOW LP LIGHT
The Fuel Gauge/Low LP Light is located on the console panel above the steering wheel in the gauge cluster. This
gauge indicates the level of fuel contained in the fuel tank. The low LP light indicates low LP pressure at the
engine.
OIL PRESSURE GAUGE
The Oil Pressure Gauge is located on the console panel above the steering wheel in the gauge cluster. The gauge
is mechanical and activated by a sender in the engine. It displays the engine oil pressure in PSI.
VOLT METER
The Volt Meter is located on the console panel above the steering wheel in the gauge cluster. The gauge indi-
cates the charging or discharging of the battery.
BRUSH ROTATION SWITCH
The Brush Rotation Switch is located on the console as shown. This switch reverses the rotation of the scrub
brushes. This switch has two positions “NORMAL” and “REVERSED”. This switch can not be activated unless
the Scrub Brush Lift Switch is in the “LOWER” position.
