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) - 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 system will shut down the engine
after 30 minutes of operation. 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.
