i.
Start
the
generator and allow iHo run for apprpxhnateJ.y
five.minutes so the engine
canwarnt
up.
:Make
sure
the
generatOr
is
operating
without
any
equipment drawing
~C
current from the generator (that is, shut off all electrical
appliances). Make sitte the engine's 8peed (HertZ) is
correct Adjtist the fuel
throttle/speed
linkage as needed to
obtain the correct engine speed before proceeding.
·
l. Referring to
the
AC
load
connections
diagram
below,
check the geiietator's no--load voltage by
:measuring
the
voltage across the neutral lead and the hot lead with a volt
meter. Make sure you record this
readitig.
The generator's
no-load voltage is 115 - 124 volts at 60.5 - 6L5 Hertz.
If
the voltage output is higher or lower than specified,
proceed.

4. Shut
off
the generator. Make sure the correct Hertz lead
(60 Hertz #6, or 50 Hertz

pltlgged into the
· capacitor(s).

5. There are three plugs grouped for the right capacitor ter-
minal, #7, #8, and
#9.
If the generator's no-load voltage is
tow,
then disconnect
the
lower numbered plug and con-
nect the plug with the next higher number. If the genera-
tor's no-load voltage
is high,
then disconnect the higher
numbered plug and connect the plug with the next lower
number. Note that the plug presently connected to this
tenninat may be any one of'the
three
plugs available.
6. · Jf the
generator's no-load voltage cannot be adjusted
because the voltage needs to
be
increased and the highest
numbered plug is already connected to the right terminal,
