Section 1 0. Service Checklist
After servicing, inspect and test the installation to
confirm that the generator set will operate to its
rated capacity. Check each
of
the areas described
below before putting the set into service.
MOUNTING
Examine all mounting bolts and supporting mem-
bers to verify that the generator set is properly
mounted. All fasteners should be tightened se-
curely,
to
prevent
them
from working loose when
subjected
to
vibration.
LUBRICATION
If the engine oil
was
drained,
fill
the crankcase with
oil
of
the recommended classification and viscosity.
Refer to the appropriate operators' manual
for
the
specific recommendations and procedures.
WIRING
Verify that all wiring connections are tight and in-
stalled properly. Make certain that wires do not run
over hot, sharp
or
rough surfaces and are not
kinked
or
worn. Check each
of
these connections:
• Load wires
• Control wires
• Ground strap
• Battery cables
INITIAL
START
ADJUSTMENTS
Gasoline sets:
Before starting the genset, check
that the idle and main mixture adjustment screw
limiter caps are in the correct position.
If the limiter
caps are missing, adjust the idle and main mixture
screws, and reinstall the limiter caps. For instruc-
tions, see the Fuel System section
of
this manual.
Mechanicalagovemor
sets:
Start the set, then im-
mediately adjust the governor speed
for
a safe no-
load operating speed (mechanical governor gen-
sets). With no load applied, listen for unusual
sounds
or
vibrations. Warm genset for
at
least 15 minutes
at
50%
to
75%
of
rated load and
check that the choke is completely open. Adjust
governor (mechanical governor gensets)
as
speci-
fied in the Governor section
of
this manual.
lA
CAUTION
I Voltage/frequency-sensitive equip-
ment
such
as
VCRs, televisions, computers,
etc.
may
be
damaged
by
power
line frequency
variations. Some solid-state devices are
pow-
ered
whenever connected to
an
AC
outlet
even
if
the device
is
not
In
actual
operation.
For
this
reason,
disconnect
all
devices which are volt-
age-
or
frequency-sensitive before attempting
any
carburetor/governor adjustments.
If
dis-
connecting
the devices Is
not
possible, open
the
circuit
breaker(s)
at
the
distribution
panel
or
at
the
generator
set,
if
so
equipped.
OUTPUT
CHECK
Apply a full load to make sure
the
set can produce
its full rated output. Use a load test panel
to
apply a
progressively greater load until full load is reached.
EXHAUST SYSTEM
With the generator set operating, inspect
the
entire
exhaust system, including the exhaust manifold,
muffler, and exhaust pipe. Make certain that the
exhaust pipe terminates beyond the perimeter
of
the
coach. Visually and audibly check
for
leaks
at
all connections, welds, gaskets, and joints. Also
make
sure that exhaust pipes
do
not heat surround-
ing areas excessively.
If
leaks are detected, cor-
rect immediately.
IAwARNINGIInha/atlon
of
exhaust
gases can re-
sult
In severe
persona/Injury
or
death.
Inspect
exhaust
system
audibly
and
visually
for
leaks
dally.
Shut
off
the engine
and
repair leaks im-
mediately.
FUEL SYSTEM
With the generator set operating, inspect the fuel
supply lines, return lines, filters, and fittings for
leaks. Check any flexible sections for cuts, cracks
and
abrasions and
make
sure they are not rubbing
against
anything '!hat cause bnaakage.
