12. Service Checklist
GENERAL
Before reinstalling the genset, repair any damage to
and seal all holes in the vapor-tight, fire-resistive
barrier between the genset and coach interior.
After servicing or reinstalling a genset conduct the
following checks and tests to determine that the
genset will operate safely and perform as required.
MOUNTING
Check for proper mounting and tighten all fasteners
securely. Make sure the air inlet and outlet openings
in the bottom of the genset are not restricted in any
way and that there is access for changing the oil fil-
ter and draining oil.
WIRING
WARNING
Batteries give off explosive gases
that can cause severe personal injury — Do not
smoke — Keep flames, sparks, pilot lights,
switches, arc-producing equipment and all oth-
er ignition sources away.
Make sure all AC output, control, ground and battery
connections are tight and properly installed. Check
wiring for cuts, cracks and abrasions and make sure
it does not rub against anything that could cause
damage.
EXHAUST SYSTEM
Make certain that the exhaust tail pipe terminates
beyond the perimeter of the vehicle and not near
vents or openable windows or doors. Test the on-
board CO alarm(s). See the Installation Manual for
important considerations concerning the installa-
tion of an exhaust system.
When the genset is up and running, look and listen
for leaks at all connections, welds, gaskets, and
joints along the whole length of the exhaust system.
Repair all leaks before putting the genset in service.
FUEL SYSTEM
Check flexible sections for cuts, cracks and abra-
sions and make sure they do not rub against any-
thing that could cause damage. On models
equipped with fuel injection, make sure proper con-
nections have been made for a fuel return line all the
way back to the fuel tank.
WARNING
Gasoline is flammable and explo-
sive and can cause severe personal injury or
death — Stop priming immediately if you smell
gasoline or see fuel leaking and clean up spilled
fuel and ventilate area before starting the gen-
set or vehicle — Do not smoke — Keep flames,
sparks, pilot lights, switches, arc-producing
equipment and all other ignition sources away
— Keep an ABC fire extinguisher handy.
Gasoline Models: Recheck all fuel connections for
tightness and then prime the fuel system by holding
the control switch at STOP/PRIME while checking
for fuel line leaks. Fix all leaks before starting the
genset.
WARNING
LPG is flammable and explosive
and can cause asphyxiation. NFPA 58, Section
1.6 requires all persons handling LPG to be
trained in proper handling and operating proce-
dures.
WARNING
LPG “sinks” and can accumulate in
explosive concentrations. Before connecting or
disconnecting the LPG fuel line, close the fuel
shutoff valve(s) at the LPG container(s) and
move the vehicle outside and away from pits,
basements, and other below-grade spaces
where LPG could accumulate.
LPG Models: Recheck all fuel connections for tight-
ness. Make sure proper connections have been
made at the LPG container(s). A genset equipped
for Low-Pressure LPG (vapor withdrawal) must not
