For any questions regarding the hazard and safety notices listed in this manual or on the product, please 
call (800) 232-1195 M-F 8-5 CST before using the generator.

DANGER: CARBON MONOXIDE

Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monox-
ide (CO). This is a poison gas you cannot see or smell.  If you can smell the generator exhaust, you are 
breathing CO. But even if you cannot smell the exhaust, you could be breathing CO. 

NEVER use a generator inside homes, garages, crawl spaces, or other partially enclosed areas.  Deadly 
levels of carbon monoxide can build up in these areas.  Using a fan or opening windows and doors does 
NOT supply enough fresh air. ONLY use a generator outside and far away from windows, doors, and 
vents.  These openings can pull in generator exhaust.

Even if you use a generator correctly, CO may leak into the home. ALWAYS use a battery-powered or 
battery-backup CO alarm in the home. If you start to feel sick, dizzy, or weak after the generator has been 
running, move to fresh air RIGHT AWAY.  See a doctor.  You may have carbon monoxide poisoning.

WARNING:  The exhaust from this product contains chemicals known to the State of Califor-
nia to cause cancer, birth defects, or other reproductive harm.

WARNING:  This generator may emit highly flammable and explosive gasoline vapors, which 
can cause severe burns or even death if ignited.  A nearby open flame can lead to explosion even 
if it isn’t directly in contact with gasoline.

SAFETY INFORMATION

1) Do not operate near open flame.

2) Do not smoke near generator.

3) Always operate on a firm, level surface.

4) Always turn generator off before refueling. Allow 
generator  to  cool  for  at  least  2  minutes  before  re-
moving fuel cap.  Loosen cap slowly to relieve pres-
sure in tank.

5) Do not overfill fuel tank.  Gasoline may expand 
during operation.  Do not fill to the top of the tank. 
Allow for expansion.

6) Always check for spilled fuel before operating.

7) Empty fuel tank before storing or transporting the 
generator.

8) Do not use in rainy conditions.

9) ALWAYS ground the generator before using it (see 
the “Ground the Generator” portion of the “Genera-
tor Preparation” section).

10)  Generator  should  only  be  plugged  into  electri-
cal devices, either directly or with an extension cord. 
NEVER connect to a building’s electrical system with-
out  a  qualified  electrician.    Such  connections  must 
comply with local electrical laws and codes. Failure to 
comply  can  create  a  back-feed,  which  may  result  in 
serious injury or death to utility workers.

11)  Use  a  ground  fault  circuit  interrupter  (GFCI)  in 
highly conductive areas such as metal decking or steel 
work. GFCIs are available in-line with some extension 
cords.

12) Do not touch bare wires or receptacles (outlets).

13) Do not allow children or non-qualified persons to 
operate the generator.
