• 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 Dealer
for parts needing repair or replacement.
• Before performing any maintenance on the generator,
disconnect its battery cables to prevent accidental start up.
Disconnect the cable from the battery post indicated by a
NEGATIVE, NEG or (–) first, then remove the POSITIVE, POS
or (+) cable. When reconnecting the cables, connect the
POSITIVE cable first, the NEGATIVE 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.
CARBON MONOXIDE HAZARDS
• The engine exhaust fumes contain carbon monoxide, which
can be DEADLY. This dangerous gas, if breathed in sufficient
concentrations, can cause unconsciousness or even death.
Do NOT alter or add to the exhaust system or do anything that
might render the system unsafe or in noncompliance with
applicable codes and standards.
• Install a battery operated carbon monoxide alarm indoors,
according to manufacturer’s instructions/recommendations.
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 voltages to
the transfer switch as does the standby generator when it
is in operation. Avoid contact with bare wires, terminals,
connections, etc., while the unit is running. Ensure all
appropriate covers, guards and barriers are in place, secured
and/or locked before operating the generator. If work must
be done around an operating unit, stand on an insulated, dry
surface to reduce shock hazard.
• Do not handle any kind of electrical device while standing
in water, while barefoot, or while hands or feet are wet.
DANGEROUS ELECTRICAL SHOCK MAY RESULT.
• The National Electrical Code (NEC) requires the frame and external
electrically conductive parts of the generator to be connected to
an approved earth ground. Local electrical codes also may require
proper grounding of the generator electrical system.
• After installing this home standby electrical system, the
generator may crank and start at any time without warning.
When this occurs, load circuits are transferred to the STANDBY
(generator) power source. To prevent possible injury if such
a start and transfer occur, always set the generator’s AUTO/
OFF/MANUAL switch to its OFF position before working on
equipment and remove the 7.5A fuse from the generator control
panel.
• In case of accident caused by electric shock, immediately shut
down the source of electrical power. If this is not possible,
attempt to free the victim from the live conductor. AVOID DIRECT
CONTACT WITH THE VICTIM. Use a nonconducting implement,
such as a dry rope or board, to free the victim from the live
conductor. If the victim is unconscious, apply first aid and get
immediate medical help.
• Never wear jewelry when working on this equipment. Jewelry
can conduct electricity resulting in electric shock, or may get
caught in moving components causing injury.
FIRE HAZARDS
• For fire safety, the generator must be installed and maintained
properly. Installation 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 in accordance with the manufacturer’s
instructions and recommendations. Following proper
installation, do nothing that might alter a safe installation and
render the unit in noncompliance with the aforementioned
codes, standards, laws and regulations.
• Keep a fire extinguisher near the generator at all times.
Extinguishers rated “ABC” by the National Fire Protection
Association are appropriate for use on the standby electric
system. Keep the extinguisher properly charged and be
familiar with its use. Consult the local fire department with any
questions pertaining to fire extinguishers.
EXPLOSION HAZARDS
• Do not smoke around the generator. Wipe up any fuel or oil
spills immediately. Ensure that no combustible materials are left
in the generator compartment, or on or near the generator, as
FIRE or EXPLOSION may result. Keep the area surrounding the
generator clean and free from debris.
• Gaseous fluids such as natural gas and liquid propane (LP)
gas are extremely EXPLOSIVE. Install the fuel supply system
according to applicable fuel-gas codes. Before placing the
home standby electric system into service, fuel system
lines must be properly purged and leak tested according to
applicable code. After installation, inspect the fuel system
periodically for leaks. No leakage is permitted.
