THE DUROMAX WAY
The DuroMax Way is more than just a brand, it is our understanding and appreciation of just how
important power can be to someone without it…
DUROMAX FOR HOME
Electricity in our home not
only provides comfort but
safety as well. From keeping
the heat or A/C on to keeping
our food cold, power is
essential to our daily lives.
Inevitability when disaster
strikes and we are left without
power for a prolonged period
of time, our way of life is
put at risk. This is by far the
most critical time for reliable
portable power.
DUROMAX FOR WORK
On the job site, portable
power allows you the ability
to get work done in remote
locations when traditional
power sources are usually
unavailable. Equipment like
table saws, sanders, and
work lights are a necessity
and portable power can
play a critical role in getting
a job done successfully and
eciently.
DUROMAX FOR PLAY
Camping outdoors in a
remote location can get one
in touch with nature and allow
them to forget the stress of
the day to day grind. Here
portable power can provide
comfort as well as safety. With
portable power, you can keep
your cell phone charged, light
up your campsite, or even
brew a cup of coee, all while
being miles from civilization.

●Keep several feet of clearance on all sides to allow proper ventilation of the generator.
WARNING: The exhaust from this product contains chemicals known to the State of
California to cause cancer, birth defects, or other reproductive harm.
WARNING: This generator produces heat when running. Temperatures near exhaust can
exceed 150°F (65°C).
●Do not touch hot surfaces. Pay attention to warning labels on the generator denoting
hot parts of the machine.
●Allow generator to cool several minutes after use before touching engine or areas

an extension cord. NEVER connect to a building electrical system without a qualied
electrician. Such connections must comply with local electrical laws and codes. Failure
to comply can create a back-ow of power, which may result in serious injury or death
to utility workers.
