Onan DFE Series User Manual

Safety Precautions
V,
Before operating the generator set, read the Operator's Man-
ual and become familiar with it and the equipment. Safe and
efficient operation can be achieved only if the equipment is
properly operated and maintained. Many accidents are
caused by failure to follow fundamental rules and precautions.
The following symbols, found throughout this manual, alert
you to potentially dangerous conditions to the operator, ser-
vice personnel, or the equipment.
This symbol warns of immediate
hazards which will result in severe
personal injury or death.
A DANGER
AWARNING
severe personal injury or death.
This symbol refers to a hazard or
unsafe practice which can result in
ACAUTION
This symbol refers to a hazard or
unsafe practice which can result in
personal injury or product or property damage.
FUEL AND FUMES ARE FLAMMABLE. Fire and explosion
can result from improper practices.
• DO NOT fill fuel tanks while engine is running, unless
tanks are outside the engine compartment. Fuel contact
with hot engine or exhaust is a potential fire hazard.
• DO NOT permit any flame, cigarette, pilot light, spark, 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 copper piping on flexi-
ble lines as copper will become brittle if continuously
vibrated or repeatedly bent
• Be sure all fuel supplies have a positive shutoff valve.
• Do not smoke while servicing lead acid batteries. Lead
acid batteries emit a highly explosive hydrogen gas that
can be ignited by electrical arcing or by smoking.
EXHAUST GASES ARE DEADLY
• Provide an adequate exhaust system to properly expel
discharged gases. Visually and audibly inspectthe exhaust
daily for leaks per the maintenance schedule. Ensure that
exhaust manifolds are secure and not warped. Do not use
exhaust gases to heat a compartment.
• Be sure the°unit is well ventilated.
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, 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 vicinity of
moving parts, or while working on electrical equipment.
Loose clothing and jewelry can become caught in moving
parts. Jewelry can short out electrical contacts and cause
shock or burning.
• If adjustment must be made while the unit is running, use
extreme caution around hot manifolds, moving parts, etc.
ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL
INJURY OR DEATH
• Remove electric power before removing protective shields
or touching electrical equipment. Use rubber insulative
mats placed on dry wood platforms over floors that are
metal or concrete when around electrical equipment. Do
not wear damp clothing (particularly wet shoes) or allow
skin surface to be damp when handling electrical
equipment.
• Use extreme caution when working on electrical compo-
nents. High voltages can cause injury or death. DO NOT
tamper with interlocks.
• Follow all applicable state and local electrical codes.
Have all electrical installations performed by a qualified
licensed electrician. Tag open switches to avoid acciden-
tal closure.
• DO NOT CONNECT GENERATOR SET DIRECTLY TO
ANY BUILDING ELECTRICAL SYSTEM. Hazardous vol-
tages can flow from the generator set into the utility line.
This creates a potential for electrocution or property
damage. Connect only through an approved isolation
switch or an approved paralleling device.
GENERAL SAFETY PRECAUTIONS
• Coolants under pressure have a higher boiling point than
water. DO NOT open a radiator or heat exchanger pres-
sure cap while the engine is running. Allow the generator
set to cool and bleed the system pressure first.
• Provide appropriate fire extinguishers and install them in
conven ient locations. Consult the local fire department for
the correct type of exti nguisher to use. Do not use foam on
•> electrical fires. Use extinguishers rated ABC by NFPA.
• Make sure that rags are not left on or near the engine.
• Remove all unnecessary grease and oil from the unit.
Accumulated grease and oil can cause overheating and
engine damage which present a potential fire hazard.
• Keep the generator set and the surrounding area clean
and free from obstructions. Remove any debris from the
set and keep the floor clean and dry.
• Do not work on this equipment when mentally or physi-
cally fatigued, or after consuming any alcohol or drug that
makes the operation of equipment unsafe.
