IMPORTANT SAFETY INSTRUCTIONS
CENTURION 3500 Home Standby Generator
Study these SAFETY RULES carefully before
installing, operating or servicing this equipment.
Become familiar with this manual and with the unit.
The generator can operate safely, efficiently and reli-
ably only if it is properly installed, operated and
maintained. Many accidents are caused by failing to
follow simple and fundamental rules or precautions.
Generac cannot possibly anticipate every possible
circumstance that might involve a hazard. The warn-
ings in th is manual, and on tags and decals affixed
to the unit, are, therefore, not all-inclusive. If using a
procedure, work method or operating technique
Generac does not specifically recommend, satisfy
yourself that it is safe for others. Also make sure the
procedure, work method or operating technique that
chosen does not render the generator unsafe.
Despite the safe design of this generator, oper-
ating this equipment imprudently, neglecting
its maintenance or being careless can cause
possible injury or death. Permit only responsi-
ble and capable persons to operate or maintain
this equipment.
Potentially lethal voltages are generated by
these machines. Ensure all steps are taken to
render the machine safe before attempting to
work on the generator.
Parts of the generator are rotating and/or hot
during operation. Exercise care near running
generators.
GEN
ERAL HAZARDS
• For safety reasons, Generac recommends that the
maintenance of this equipment is carried out by a
Generac Authorized Service Dealer.
• The generator engine releases DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concentra-
tions, can cause unconsciousness or even death.
Never operate the generator inside any garage or
other enclosed area. DO NOT OPERATE THE
GENERATOR IF THE EXHAUST SYSTEM IS
LEAKING OR HAS BEEN DAMAGED. SYMPTOMS
OF CARBON MONOXIDE POISONING ARE (a)
inability to think coherently, (b) nausea, (c) vomit-
ing, (d) twitching muscles, (e) throbbing temples,
(f) dizziness, (g) headaches, (h) weakness, and (i)
sleepiness. IF EXPERIENCING ANY OF THESE
SYMPTOMS, MOVE INTO FRESH AIR IMMEDI-
ATELY. IF SYMPTOMS PERSIST, GET MEDICAL
HELP. Shut down the generator and do not operate
it until it has been inspected and repaired.
• The engine exhaust fumes contain carbon monox-
ide, which can be DEADLY. This dangerous gas, if
breathed in sufficient concentrations, can cause
unconsciousness or even death. This exhaust sys-
tem must be installed properly, in strict compliance
with applicable codes and standards. Following
installation, do nothing that might render the sys-
tem unsafe or in noncompliance with such codes
and standards. Never operate this equipment with
a leaking or defective exhaust system.
• Keep hands, feet, clothing, etc., away from drive
belts, fans, and other moving or hot parts. Never
remove any drive belt or fan guard while the unit is
operating.
• Adequate, unobstructed flow of cooling and venti-
lating air is critical to correct generator operation
and is required to expel toxic fumes and fuel
vapors from the generator. Without sufficient cool-
ing airflow, the engine/generator overheats, which
causes serious damage to the generator. Do not
alter the installation or permit even partial block-
age of ventilation provisions, as this can seriously
affect safe operation of the generator.
• When working on this equipment, remain alert at
all times. Never work on the equipment when
physically or mentally fatigued.
• Inspect the generator regularly, and contact the
nearest Generac Authorized Service Dealer imme-
diately for parts needing repair or replacement.
• Before performing any maintenance on the genera-
tor, disconnect its battery cables to prevent acci-
dental start up. Disconnect the cable from the bat-
tery post indicated by a NEGATIVE, NEG or (–)
first. Reconnect that cable last.
