Study these SAFETY RULES carefully before
installing, operating or servicing this equipment.
Become familiar with this Owner’s Manual and with
the unit. The generator(s) can operate safely, effi-
ciently and reliably 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 anticipate every possible circum-
stance 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 proce-
dure, work method or operating technique Generac
does not specifically recommend, ensure that it is
safe for others. Also make sure the procedure, work
method or operating technique chosen does not ren-
der the generator(s) unsafe.

Despite the safe design of this generator, 
operating this equipment imprudently, neglect-
ing its maintenance or being careless can cause 
possible injury or death. Only responsible and
capable persons are 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(s).

Parts of the generator(s) are rotating and/or
hot during operation. Exercise care near run-
ning generators. 

GENERAL HAZARDS

• For safety reasons, Generac requires that the

installation, initial start-up and maintenance of
this equipment is carried out by a Generac
Authorized Dealer.

• 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 compli-
ance with applicable codes and standards.
Following installation, do nothing that might ren-
der the system unsafe or in noncompliance with
such codes and standards.

• Keep hands, feet, clothing, etc., away from drive

belts, fans, and other moving or hot parts. Never
operate the unit with any drive belt or fan guard
removed.

• Adequate, unobstructed flow of cooling and venti-

lating air is critical to correct generator(s) opera-
tion. Do not alter the installation or allow even par-
tial blockage of ventilation provisions, as this can
seriously affect safe operation of the generator(s).

• When working on this equipment, remain alert at

all times. Never work on the equipment when
physically or mentally fatigued.

• Inspect the generator(s) regularly, and repair or

replace all damaged or defective parts immediate-
ly. Always use factory-authorized parts.

• Turn off the AC power to the battery charger before

disconnecting the battery to minimize the chance
of equipment damage.

• Before performing any maintenance on the genera-

tor(s), disconnect its battery cables to prevent acci-
dental start-up. Remove control panel fuse, then
disconnect the cable from the battery post indicat-
ed by a NEGATIVE, NEG or (–) first. Reconnect
that cable last, then reinstall control panel fuse.

• Never use the generator(s) or any of its parts as a

step. Stepping on the unit can stress and break
parts, and may result in dangerous operating con-
ditions from leaking exhaust gases, fuel leakage,
oil leakage, etc.
