Product Description
Engineered for high performance, the professional-grade Generac XG4000 portable gas-powered generator
(model 5778) is ideal for both residential and light commercial applications, providing a reliable 4,000-watt
power supply wherever you need it and a maximum power output of 4,500 watts. The XG Series employs the
Generac OHVI engine, which has a significantly longer life than competitive engines--up to an unprecedented
three to four times longer

2. OHVI engine provides a
significantly longer lifespan.
Its compact design, smaller footprint, semi-solid, rally-style wheels and fold-down locking handles make this XG
Series generator easier to transport. Additionally, its durable construction with oversized full-wrap frame tubing
and impact resistant corners minimizes damage from rough handling. And all XG Series generators come with
covered outlets for added protection from the environment and rugged working conditions, plus an hour meter
to help track maintenance requirements.
Note for California residents: This model is not CARB-compliant. Units sold to California must be
CARB-compliant.
Powerful, Long-Lasting OHVI Engine
The Generac OHVI (Overhead Valve Industrial) engine is the only engine designed specifically for generator use.
Generators are often required to run for hours at a time, or even day after day. Engines adapted from other
applications can overheat and may have shorter lifespans. It offers advanced heat reduction technology such
as plateau-honed cylinders that lessen break-in time, plasma moly ring seals that help to keep excess oil out of
the cylinder, and graphite piston inserts that provide a smoother surface for the piston to move against--all
helping to contribute to a significantly longer engine life.
Maintenance costs are reduced with a spin-on automotive-style oil filter that's larger than a standard filter,
catching more particles so oil stays cleaner for a longer amount of time. Service intervals are up to twice as
long as competitive engines, approximately 2 years or 200 hours of operation.
Plenty of Wattage to Run a Full Range of Appliances
The Generac XG4000 supplies 3,600 output watts and 4,500 maximum watts (for start-up of devices). It has an
A/C voltage of 120/240 and a frequency of 60 hertz.
XG Series control panel (see larger image).
For unexpected blackouts, this is enough wattage to run home appliances such as security systems, computers,
and electric range tops. For construction and landscaping applications, it's enough to support devices such as
trimmers, belt sanders, and circular saws. And for camping and outdoor events, it can run portable stereos,

3. outdoor lights, and electric grills.
(Note: All appliances should be checked for actual wattage ratings.)
This generator's sturdy, 4.5-gallon steel tank ensures a full 13 hours of operation at a 50-percent load, letting
you relax for hours of use. You can monitor fuel levels at a glance with the tank's built-in fuel gauge, while the
unique lighted Power Bar displays available wattage. Its 120-volt outlets are circuit-breaker protected, guarding
against power overloads and allowing the generator to smoothly send power to your appliances.
This generator is backed by a two-year limited residential warranty (one-year warranty for commercial
applications).
