CONDUCTING GENERAL INSPECTIONS
Inspect the genset before the first start of the day
and after every eight hours of operation.
Oil Level
Check engine oil level (Page 3-3).
Exhaust System
Look and listen for exhaust system leaks while the
genset is running. Shut down the genset if a leak is
found and have it repaired before operating the gen-
set again.
Look for openings or holes between the genset
compartment and vehicle cab or living space if the
genset engine sounds louder than usual. Have all
such openings or holes closed off or sealed to pre-
vent exhaust gases from entering the vehicle.
Replace dented, bent or severely rusted sections of
the tailpipe and make sure the tailpipe extends at
least 1 inch (25.4 mm) beyond the perimeter of the
vehicle.
Park the vehicle so that genset exhaust gases dis-
perse away from the vehicle. Barriers such as walls,
snow banks, high grass and brush and other ve-
hicles can cause exhaust gases to accumulate in
and around the vehicle.
Do not operate power ventilators or exhaust fans
while the vehicle is standing with the genset run-
ning. The ventilator or fan can draw exhaust gases
into the vehicle.
Check all CO monitors to assure proper operation.
WARNING
EXHAUST GAS IS DEADLY! Do not
operate the genset if there is an exhaust leak or
any danger of exhaust gases entering or being
drawn into the vehicle.
WARNING
Do not park the vehicle in high grass
or brush. Contact with the exhaust system can
cause a fire.
Fuel System
Check for leaks at the hose, tube and pipe fittings in
the fuel supply and return systems while the genset
is running and while it is stopped. Do not use a flame
to check for LPG leaks. Check flexible fuel hose
sections for cuts, cracks, and abrasions. Make sure
the fuel line is not rubbing against other parts. Re-
place worn or damaged fuel line parts before leaks
occur.
If you smell gas, close the LPG container shutoff
valve and have the genset serviced before using it
again.
WARNING
Gasoline and LPG are highly flam-
mable and explosive and can cause severe per-
sonal injury or death. Shut down the genset and
repair leaks immediately.
Battery Connections
Check the battery terminals for clean, tight connec-
tions. Loose or corroded connections have high
electrical resistance which makes starting harder.
See MAINTAINING THE BATTERY AND BATTERY
CONNECTIONS (Page 3-5).
Mechanical
Look for mechanical damage. Start the genset and
look, listen and feel for any unusual noises and
vibrations.
Check the genset mounting bolts to make sure they
are secure.
Check to see that the genset air inlet and outlet
openings are not clogged with debris or blocked.
Clean accumulated dust and dirt from the genset.
Do not clean the genset while it is running or still hot.
Protect the generator, air cleaner, control panel, and
electrical connections from water, soap and clean-
ing solvents.
WARNING
Always wear safety glasses when
using compressed air, a pressure washer or a
steam cleaner to avoid severe eye injury.
