ENGINE CONTROLS (Items 6 Through to
13)
6. ENGINE HOUR METER / FUEL GAUGE
Combination hour meter fuel level gauge. The hour
meter displays the total time that the engine has
been running. This meter is a useful indicator for
scheduling preventive maintenance. The fuel gauge
displays the level of diesel fuel in the fuel tank. The
operator must watch the fuel level closely to prevent
running out of fuel and possibly having to bleed the
system.
7. RUN STOP SWITCH
The RUN position energizes the hold coil of the fuel
solenoid, hour meter, and rotor flashing circuit. The
STOP position stops the engine.
NOTE: Do not leave switch in RUN position when
the engine is not running. In the RUN posi-
tion the battery will be discharged.
8. START PUSH BUTTON
Energizes the starter motor to crank the engine.
With the RUN / STOP switch in the RUN position,
push and hold the Start button to crank the engine;
release as the engine starts. Do not press while
engine is running as this can cause damage to the
ring gear and/or starter motor.
9. CIRCUIT BREAKER
The battery circuit breaker protects the engine cir-
cuitry that powers the three gauges, fuel/hours, tem-
perature and pressure. It also protects the engine
shutdown relay, timer delay relay, hot start relay
hold solenoid, and flashing circuitry. When the cir-
cuit breaker opens because of a fault, the engine
will crank but will not start.
10. OIL TEMPERATURE GAUGE
An indicator of engine oil temperature.
OPERATION
11. OIL PRESSURE GAUGE
An indicator of engine oil pressure.
12. ENGINE PROTECTION
A warning indicator light for high oil temperature or
low oil pressure. The light remains off with proper
oil temperature and proper oil pressure. If a fault is
detected the light will turn on and the engine pro-
tection system will stop the engine. The light will
remain on when the engine has been shut down.
In order to try and re-start the engine the engine
protection system must be reset by returning the
RUN-STOP switch to the STOP position.
NOTE: The light remains off when the RUN-STOP
switch is in the RUN position prior to start-
ing the engine. However if the engine is not
started within 60 seconds the light will come
on. When this happens the RUN-STOP
switch must be returned to the STOP posi-
tion to reset the engine protection system
and light.
13. BATTERY CHARGING LIGHT
An indicator light for low/no battery charging. The
light is off when the battery charging system is
functioning normally. If light turns on, the alternator
or the voltage regulator may not be operating cor-
rectly or the cooling blower belt may be broken.
The light will remain on when the engine is
stopped and the RUN / STOP switch is in the RUN
position.
