If the fuel system was worked on, check that the idle
and main adjustment screws are adjusted as de-
scribed in the fuel system sections of Section
8. Pri-
mary Engine Systems
before starting the genset.
Reinstall adjustment screw limiter caps.
Start the genset, then immediately adjust the gover-
nor speed for a safe no-load operating speed. With
no load applied, listen for unusual sounds or vibra-
tions. Warm up the genset for at least 15 minutes at
50% to 75% of rated load and check that the choke
is completely open. Adjust the carburetor and gov-
ernor as specified in the governor and fuel system
sections of Section
8. Primary Engine Systems
.
EXHAUST SYSTEM
With the genset operating, inspect the entire ex-
haust system including the muffler and exhaust
pipe. Make certain that the exhaust pipe terminates
beyond the perimeter of the coach. Visually and au-
dibly check for leaks at all connections, welds, gas-
kets, and joints. Also make sure that exhaust pipes
do not heat surrounding areas excessively. If leaks
are detected, correct immediately.
WARNING
Inhalation of exhaust gases can re-
sult in severe personal injury or death. Inspect
exhaust system audibly and visually for leaks.
Shut off the engine and repair leaks immediate-
ly.
FUEL SYSTEM
With the genset operating, inspect the fuel supply
line and fittings for leaks. Check flexible section for
cuts, cracks and abrasions and make sure it is not
rubbing against anything that could cause damage.
WARNING
Leaking fuel creates a fire hazard
which can result in severe personal injury or
death if ignited by flame, spark, pilot light, ciga-
rette, arc-producing equipment, electrical
switch, or other ignition source. If fuel leaks are
detected, shut off the genset and correct leak
immediately.
OUTPUT CHECK
Apply a full load to make sure the genset can pro-
duce its full rated output. Use a load test panel to ap-
ply a progressively greater load until full load is
reached.
CONTROL
Stop and start the genset several times at the gen-
set control and remote control (if equipped) to verify
that it functions properly.
MECHANICAL
Stop the genset and inspect it for leaking gaskets,
loose fasteners, damaged components, or interfer-
ence problems. Repair as required. Inspect the
genset compartment and verify that there are no
breaks or openings in the vapor-proof wall that sep-
arates the compartment from the vehicle interior.
Seal openings as required. Make sure that all
soundproofing material is in place.
