Instrumentation
Familiarize yourself with all instruments on the tractor. Many are designed to alert you to
conditions that must be addressed. When operating the tractor, frequently check gauges to
insure everything is functioning as it should be and in the normal range.
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 (138414 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 engine and check the oil level. If your tractor is equipped with a Sauer display, an error
will be displayed and the tractor will power down after 15 seconds. Add oil as necessary. Check for possible causes (leaks) for the low oil pressure. If low oil pressure
should recur, follow the above directions and contact equipment maintenance personnel to determine cause of recurring low oil pressure.
Caution: Do not continue to operate the tractor as long as the oil
pressure is below the normal operating range. Continued operation 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 working. If the value falls below 12 volts with no accessories operating and the engine running, 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.
TT
QA044 REV05 9.4.14
5-5
General Usage
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.
Temperature Gauge
This gauge indicates the temperature of the engine coolant. The temperature will rise
to the normal range as the engine warms. If the value moves above the normal range
of 225°F (107°C), the engine is overheating. If your tractor is equipped with a Sauer
display, an error will be displayed and the tractor will power down after 15 seconds.
Check for proper airflow through the radiator and that there is not a coolant leak.
Running the engine while overheating can cause engine damage.
Caution: If the engine continues to overheat, have the cooling
system checked.

ON POSITION - The fuel pump, electrical system, accessories and fueltemperature-voltage gauges are activated. The oil pressure gauge will not fully
activate until the engine is started.
START POSITION – This is used to start the engine. The engine will crank until
you release the ignition switch. When the ignition switch is released in the start
position, you must turn the switch to the "OFF" position first before returning to
the start position. This is to prevent trying to start the engine when it is already
running (anti-restart protection).
OFF POSITION - This is used to shut down the engine and turn all electrical
power off (including accessories). Never leave the tractor unattended with the
engine running or the ignition switch in the "ON" position, as this can result in a
run-down battery.
Ignition Switch (4TNV98 Engines)
Your tractor is equipped with either a keyed or keyless ignition switch. The switch provides power to the Sauer display which is used to start the engine.
Headlight switch
The headlight switch is an on/off type. There is no hi/low beam control position.
Heat Temperature Control (Option)
The heat temperature control is a push/pull control cable and is used to adjust the air
temperature from the heater in a cab. Pull up to set at desired temperature. Push
down to turn heat off.
Heater Fan Control Switch (Option)
The heater fan switch has three positions, OFF, LOW and HIGH.
Windshield Wiper Switch (Option)
The windshield wiper switch (located on the wiper motor) has an on/off position. The
wiper has only one speed.

General Usage
Transmission Operation
The transmission is controlled by a "lever type" gearshift located in the instrument
panel or console. The control has six selector positions- P (Park), R (Reverse), N
(Neutral), D (Drive), 2 (Second) and 1 (First). In entering or leaving a gear position, the
lever must be moved past a gate. To do this, place the palm of your hand on the top of
the selector lever and reach under with your fingers and grip the release mechanism
and pull up (or squeeze). Shift to the desired position and release the selector.
1. Keep your foot ON the brake pedal and OFF the accelerator and release the
parking brake before shifting the transmission into gear.
2. Before shifting from forward to reverse or reverse to forward, bring the
vehicle to a complete stop. Do not shift into gear except when the engine is
at idle speed.
3. Before dismounting from the tractor, place the transmission in "PARK" and
apply the parking brake.
Parking Brake
The parking brake is operated by hand lever action. By pulling back on the lever, you
activate and set the brake. Pushing forward will release the brake. The brake is
adjustable for braking pressure by rotating the knob on the end of the handle lever. A
clockwise direction is used to increase the brake holding pressure and counter
clockwise to reduce the pressure.
All trucks feature a safety system to protect the parking brake from accidental misuse.
Depending on engine type, either the accelerator pedal will not respond when the parking brake is engaged, or the engine will shut off when both the parking brake is engaged and the truck is shifted out of Park or Neutral.
Foot Brake
The foot brake is power assisted and should be applied with a steady and firm downward pressure. If the power assist should fail, the brakes will still operate mechanically
but will require increased foot pressure. Always anticipate that you may have to stop
unexpectedly.
Speed should always be adjusted to allow for a safe and controlled stop. Adjust your
speed based on the surface conditions, the space available for stopping and the
weight of the load being moved. Be aware of your surroundings. Always be prepared
to stop and avoid sudden stops.
Caution: If driving on wet or slippery surfaces, lower speed and
allow for more stopping distance. Do not spin the wheels when
starting up as this may cause damage to the drive mechanisms.
