INSTRUMENT PANEL
1. Cold Starting Indicator Light — Illuminates
when the key switch is turned to the “HEAT”
position. It remains lit for approximately 5
seconds when the key is held in position, during
which time the glow plugs are heating the
precombustion chambers.
2. Engine Oil Pressure Warning Light —Illumi-
nates with the key switch in the “ON” or “HEAT”
positions and remains lit for a short period of time
after the engine is started. The light indicates oil
pressure only and goes out when sufficient oil
pressure is present at the oil sender. If the bulb
becomes lit during operation, stop the tractor
engine immediately and investigate the cause.
3. Battery Charge Warning Light — Illuminates
when the key switch is in the “ON” or “HEAT”
positions and goes out when the engine is
started. If this bulb becomes lit during operation,
it indicates that the charging system is not
operating normally. As the battery can become
fully discharged under these conditions, the
problem should be investigated as soon as
possible.
4. Proof Meter —Records the hours and portions of
hours that your tractor has been operated based
on an average engine speed of 1833 RPM.
Engine speeds below 1833 RPM accumulate
engine hours at a slower rate than clock hours.
Engine speeds above 1833 RPM accumulate
engine hours faster than clock hours. Use the
proof meter as a guide to determine hourly
service and maintenance intervals.
5. Fuel Gauge —Indicates the amount of diesel fuel
remaining in the tank. The gauge is activated
when the key switch is in the “ON” or “HEAT”
positions. It will register empty with the key switch
in the “STOP” position.
6. Flasher Warning Lights —Operate when the
flasher switch is turned on, regardless of the key
switch position. Use the flasher warning lights
and the SMV emblem when traveling on public
roads, day or night.
7. Flasher Turn Lights —Operate when the turn
signal switch is activated. Rotate the switch
counterclockwise for right turns, the right arrow
will flash. Rotate the switch clockwise for left
turns, the left arrow will flash. The key switch has
to be in the “RUN” position.
8. Temperature Gauge —Indicates coolant tem-
perature. It is activated when the key switch is
turned to the “ON” or “HEAT” positions. The
gauge will register cold with the key switch in the
“STOP” position. If the needle registers in the
green range of the gauge, this indicates a normal
operating temperature. If the needle moves to
the red portion of the gauge, this indicates an
overheated condition. Stop the tractor engine
immediately and investigate the cause.
9. Tachometer —Registers engine RPM (Revolu-
tions Per Minute). The gauge is marked in
increments of 100 and will return to zero when
the engine is not running.
