Power Systems, Inc.
Study these SAFETY RULES carefully before installing,
operating or servicing this equipment. Become familiar
with this
Owner’s Manual
and with the unit. The genera-
tor can operate safely, efficiently and reliably only if it is
properly installed, operated and maintained. Many acci-
dents are caused by failing to follow simple and funda-
mental rules or precautions.
Generac cannot anticipate every possible circumstance that
might involve a hazard. The warnings in this manual, and
on tags and decals affixed to the unit are, therefore, not
all-inclusive. If using a procedure, work method or operat-
ing technique that Generac does not specifically recom-
mend, ensure that it is safe for others. Also make sure the
procedure, work method or operating technique chosen
does not render the generator unsafe.
Despite the safe design of this generator,
operating this equipment imprudently, neglecting
its maintenance or being careless can cause
possible injury or death. Permit only responsible
and capable persons to install, operate or main-
tain 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 gen-
erators.
GENERAL HAZARDS
• For safety reasons, Generac recommends that this equip-
ment be installed, serviced and repaired by a Generac
Authorized Service Dealer or other competent, qualified
electrician or installation technician who is familiar with
applicable codes, standards and regulations. The operator
also must comply with all such codes, standards and regu-
lations.
• Installation, operation, servicing and repair of this (and
related) equipment must always comply with applicable
codes, standards, laws and regulations. Adhere strictly to
local, state and national electrical and building codes.
Comply with regulations the Occupational Safety and
Health Administration (OSHA) has established. Also,
ensure that the generator is installed, operated and serv-
iced in accordance with the manufacturer’s instructions
and recommendations. Following installation, do nothing
that might render the unit unsafe or in noncompliance with
the aforementioned codes, standards, laws and regulations.
• The engine exhaust fumes contain carbon monoxide gas,
which can be DEADLY. This dangerous gas, if breathed in
sufficient concentrations, can cause unconsciousness or
even death. For that reason, adequate ventilation must be
provided.
• 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 ventilating air is
critical to prevent buildup of explosive gases and to ensure
correct generator operation. Do not alter the installation or
permit even partial blockage of ventilation provisions, as
this can seriously affect safe operation of the generator.
• Keep the area around the generator clean and uncluttered.
Remove any materials that could become hazardous.
• 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 promptly repair or
replace all worn, damaged or defective parts using only fac-
tory-approved parts.
• Before performing any maintenance on the generator, dis-
connect its battery cables to prevent accidental start-up.
Disconnect the cable from the battery post indicated by a
NEGATIVE, NEG or (–) first. Reconnect that cable last.
• Never use the generator or any of its parts as a step.
Stepping on the unit can stress and break parts, and may
result in dangerous operating conditions from leaking
exhaust gases, fuel leakage, oil leakage, etc.
ELECTRICAL HAZARDS
• All generators covered by this manual produce dangerous
electrical voltages and can cause fatal electrical shock.
Utility power delivers extremely high and dangerous volt-
ages to the transfer switch as well as the standby generator.
Avoid contact with bare wires, terminals, connections, etc.,
on the generator as well as the transfer switch, if applica-
ble. Ensure all appropriate covers, guards and barriers are
in place before operating the generator. If work must be
done around an operating unit, stand on an insulated, dry
surface to reduce shock hazard.
