Oil Pressure Gauge
The gauge will vary within the normal operating range of 10-50 psi (69-345 kPa) for
gasoline engines (TME27, H153, 6G72, LRG725 and ESG642) and 20-60 psi (138-
414 kPa) for Diesel engines (4TNV98, 4TNV98T, TMD27, TMDT27, 4JB1, 4JG1 and
4JG1T. If the value drops below the normal range when the engine is running, there is
a loss of pressure. If this occurs, stop the tractor as soon as possible, shut off the en-
gine and check the oil level. Add oil as necessary. Check for possible causes (leaks)
for the low oil pressure. If low oil pressure should reoccur, follow the above directions
and contact equipment maintenance personnel to determine cause of recurring low oil
pressure.
General Usage
5-5
Caution: Do not continue to operate the tractor as long as the oil
pressure is below the normal operating range. Continued opera-
tion may cause severe internal engine damage.
Hour Meter
The hour meter indicates the amount of running time on the engine. It is used as a
guide as to when preventative maintenance procedures should be done. (See
"Preventative Maintenance Schedules" following this section of the manual).
Voltage Gauge
This gauge indicates the battery voltage available (normally 12-14 volts). After starting
the engine, the value should be about 14 volts, which indicates the alternator is work-
ing. If the value falls below 12 volts with no accessories operating and the engine run-
ning, have the electrical system checked by maintenance personnel. The value may
fall below 12 volts at engine idle and accessories operating--shut off all accessories to
check that pointer returns to 12 volts or higher while the engine is running. Also by
adding a little throttle to increase engine speed, the value should climb back into the
correct voltage position.
Fuel Gauge
The fuel gauge indicates the approximate fuel level in the fuel tank. The reading may
fluctuate during starting up, cornering and stopping. It is recommended that the fuel
supply be kept at 1/4 or higher levels to prevent any water condensation in the fuel
tank from entering the fuel lines.
