ENGINE CONTROLS (Items 1 through 8)
1. RUN STOP SWITCH
When placed in the "RUN" position, this switch ener-
gizes the fuel solenoid and other electric accessories.
When placed in the "STOP" position, the flow of fuel to
the injection pump is stopped to shut down the engine.
(Note: If the switch is left in the "RUN" position and the
engine is not running, the fuel solenoid will be engaged
for 15 seconds and then shut down. This is to protect
the battery from discharge. After 15 seconds, the Run
/ Stop switch must be toggled off then on before start-
ing.)
2. START PUSHBUTTON
Energizes the starter motor to crank the engine. With the
engine "Run / Stop" switch in the "Run" position, push and
hold the Start button to crank the engine; release as the
engine starts. Start button must be depressed for a minimum
of two seconds. Do not press while engine is running since
this can cause damage to the ring gear and/or starter motor.

3. FUEL LEVEL GAUGE AND LIGHT
(K1639-2 only on codes 10838 and
below) - Displays the level of diesel fuel
in the 25-gallon fuel tank. The yellow light turns on
when the fuel gage reaches the reserve level. Once
the reserve level is reached, the engine protection sys-
tem will shut down the engine after 30 minutes of oper-
ation. The machine can be restarted and operated for
an additional 30 minutes before the protection system
will shut down the engine. This ability to override the
engine protection is to allow the operator to "finish up"
if necessary. The operator must watch the fuel level
closely to prevent running out of fuel and having to
bleed the system.
