IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS − This manual con-
tains important instructions that should be followed
during installation and maintenance of the genera-
tor and batteries.
Before operating the generator set, read the Op-
erator’s Manual and become familiar with it and the
equipment. Safe and efficient operation can be
achieved only if the equipment is properly oper-
ated and maintained. Many accidents are caused
by failure to follow fundamental rules and precau-
tions.
The following symbols, found throughout this
manual, alert you to potentially dangerous condi-
tions to the operator, service personnel, or the
equipment.
This symbol warns of immediate
hazards which will result in severe personal in-
jury or death.
WARNING
This symbol refers to a hazard or un-
safe practice which can result in severe person-
al injury or death.
CAUTION
This symbol refers to a hazard or un-
safe practice which can result in personal injury
or product or property damage.
FUEL AND FUMES ARE FLAMMABLE
Fire, explosion, and personal injury or death can re-
sult from improper practices.
DO NOT fill fuel tanks while engine is running,
unless tanks are outside the engine compart-
ment. Fuel contact with hot engine or exhaust
is a potential fire hazard.
DO NOT permit any flame, cigarette, pilot light,
spark, arcing equipment, or other ignition
source near the generator set or fuel tank.
Fuel lines must be adequately secured and
free of leaks. Fuel connection at the engine
should be made with an approved flexible line.
Do not use zinc coated or copper fuel lines with
diesel fuel.
Be sure all fuel supplies have a positive shutoff
valve.
Be sure battery area has been well-ventilated
prior to servicing near it. Lead-acid batteries
emit a highly explosive hydrogen gas that can
be ignited by arcing, sparking, smoking, etc.
EXHAUST GASES ARE DEADLY
Provide an adequate exhaust system to prop-
erly expel discharged gases away from en-
closed or sheltered areas and areas where in-
dividuals are likely to congregate. Visually and
audibly inspect the exhaust daily for leaks per
the maintenance schedule. Make sure that ex-
haust manifolds are secured and not warped.
Do not use exhaust gases to heat a compart-
ment.
Be sure the unit is well ventilated.
Engine exhaust and some of its constituents
are known to the state of California to cause
cancer, birth defects, and other reproductive
harm.
MOVING PARTS CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH
Keep your hands, clothing, and jewelry away
from moving parts.
Before starting work on the generator set, dis-
connect battery charger from its AC source,
then disconnect starting batteries, negative (−)
cable first. This will prevent accidental starting.
Make sure that fasteners on the generator set
are secure. Tighten supports and clamps,
keep guards in position over fans, drive belts,
etc.
Do not wear loose clothing or jewelry in the vi-
cinity of moving parts, or while working on elec-
trical equipment. Loose clothing and jewelry
can become caught in moving parts.
If adjustment must be made while the unit is
running, use extreme caution around hot man-
ifolds, moving parts, etc.
DO NOT OPERATE IN FLAMMABLE AND
EXPLOSIVE ENVIRONMENTS
Flammable vapor can cause an engine to over-
speed and become difficult to stop, resulting in pos-
sible fire, explosion, severe personal injury and
death. Do not operate a generator set where a flam-
