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.
ENGINE OIL PRESSURE GAUGE
The engine oil pressure gauge registers the engine
oil pressure. Normal engine oil pressure ranges from
20 to 35 psi (140 to 240 kPa) at full engine throttle. If
the gauge registers an oil pressure reading below 7
psi (50 kPa), stop the engine immediately and
determine the cause. Failure to stop the engine will
result in engine damage.
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 be 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.
STEERING WHEEL
The automotive-type steering wheel controls a
steering cylinder connected to the rear wheel
support. It is recommended that the steering wheel
not be turned excessively when the engine is not
operating. A horn button is located in the center of
the steering wheel.
FUEL LEVEL GAUGE
The fuel level gauge is present on all gasoline
powered machines. It indicates how much fuel is left
in the fuel tank.
VOLTAGE GAUGE
The voltage 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 are in need of repair.
OPERATING LIGHTS SWITCH
The operating lights switch controls the
headlights, taillights, and side brush spot light. To
operate the lights, place the switch in the bottom
position. To turn off the lights, place the switch in the
top position.
IGNITION SWITCH
The key operated ignition switch starts the engine.
To start the engine, turn the key clockwise. To turn
the ignition off, turn the key counterclockwise.
NOTE: Do not operate the starter motor for more than
10 seconds at a time or after the engine has started.
Allow the starter to cool between starting attempts.
The starter motor may be damaged if it is operated
incorrectly.
FOR SAFETY: Before starting machine, make sure
all safety devices are in place and operate
properly.
