e. If the engine does not start, close choke to full.
Take one pull of starter rope. If engine starts, run
Figure 2-2. Engine starting controls.
Step 1.
Set the circuit breaker to OFF or OPEN position.
I
Step 2.
Set the fuel selector valve to the TANK or AUX
position–whichever fuel source you are using.
Step 3.
Set the output selector switch-it is inside the con-
trol box–to the generator (voltage) output that
matches the connected load.
Step 4.
Turn the voltage adjusting rheostat all the way to
the left.
Step 5.
Set the carburetor throttle control in GOVERN or
RUN position.
Step 6.
a. Set the engine RUN-OFF switch to RUN
position.
b. Put the choke in about a 3/4-closed position.
WARNING
Serious eye injury can result from the
starter rope knot. Wear eye protection
when pull starting engine.
engine at l/2-choke, then open choke as steady
engine operation permits.
CAUTION
Unnecessary or excessive use of the choke
can cause the lubricating oil to dilute.
e. Carburetor Control. The carburetor control (fig.
2-2) is a lever that is held in the selected position by
a springloaded, knurled nut. The control assembly is
located at the top front of the carburetor at the right
front of the engine. Engine speed can be increased by
moving the lever away from the engine and can be
decreased by moving the lever toward the engine.
f. AC Voltmeter (AC Unit). The AC voltmeter (A,
fig. 2-3), located on the rear face of AC control box, in-
dicates the voltages at end load toggle switch (S1).
The meter is graduated from 0 to 250 volts. It normal-
ly should read either 120 V or 240 V.
g. Frequency Meter (AC Unit). The frequency
meter (A, fig. 2-3) located next to the voltmeter on the
rear face of the control box, indicates the frequency
of the generator output. The frequency meter is
graduated from 55 to 65 CPS (cycles per second) =
hertz. The normal reading should be 60 CPS (hertz).
h. Load Switch (AC Unit). The load switch (A, fig.
2-3) is a toggle-type, two-position switch that is
located on the left side of the rear face of the control
box. It is used to connect and disconnect the
generator set to and from the load.
i.
Variable Resistor (AC Unit). The variable
resistor (A, fig. 2-3) is located on the rear face of the
control box. A rotary-type control, it is used to con-
trol the output voltage of the generator set.
j. Voltage Change Switch (AC Unit). The voltage
change switch (A, fig. 2-3) is a two-position, pull-
release, toggle-type switch. It is located at the top left
center of the control box under the cover. It is used
only when setting up the equipment to adapt the unit
either to a 120 volt or 240 volt load.
k. DC Voltmeter(DC Unit). The DC voltmeter (B,
fig. 2-3), located on the left rear face of the DC control
box, indicates the voltage at the circuit breaker. The
meter is graduated from 0 to 50 volts. It should nor-
mally read 28 volts.
c. Make one pull of the starter rope with a quick,
steady motion.
d. If the engine starts, open choke as steady engine
operation permits.
