Set up Precautions
1. Gasoline fuel and fumes are flammable, and
potentially explosive. Use proper fuel storage
and handling procedures. Do not store fuel
or other flammable materials nearby.

Safety

2. Have multiple ABC class fire extinguishers nearby.
3. Operation of this equipment may create sparks that
can start fires around dry vegetation.
A spark arrestor may be required. The operator
should contact local fire agencies for laws or
regulations relating to fire prevention requirements.
4. Set up and use only on a flat, level,
well‑ventilated surface.

the circuit breaker. Slightly overloading the
generator may not trip the circuit breaker,
but will lead to premature generator failure.
14. Do not attempt to connect or disconnect
load connections while standing in water,
or on wet or soggy ground.

2. Never use a generator indoors, including in
garages, basements, crawl spaces and sheds.
Opening doors and windows or using fans will NOT
prevent carbon monoxide build up in the home.
3. When using generators, keep them outdoors
and far away from open doors, windows,
and vents to avoid toxic levels of carbon
monoxide from building up indoors.
4. If you start to feel sick, dizzy, or weak while
using a generator, get to fresh air right away.
The carbon monoxide from generators can
quickly lead to full incapacitation and death.
5. Keep children away from the equipment,
especially while it is operating.
6. Keep all spectators at least six feet
from the Engine during operation.
7. Fire Hazard! Do not fill fuel tank while engine is
running. Do not operate if gasoline has been spilled.

with grounded surfaces such as pipes,
radiators, ranges, and refrigerators.
19. Only use a suitable means of transport and
lifting devices with sufficient weight bearing
capacity when transporting the generator.
20. Secure the generator on transport vehicles to
prevent it from rolling, slipping, and tilting.
21. Industrial applications must follow
OSHA requirements.
22. Do not leave the generator unattended when it is
running. Turn off the generator (and remove safety
keys, if available) before leaving the work area.

Operation

NEVER use inside a home or garage,
EVEN IF doors and windows are open.

11. Before connecting an appliance or power cord
to the generator: Make sure that it is in good
working order. Faulty appliances or power cords
can create a potential for electrical shock.

23. The generator can produce high noise levels.
Prolonged exposure to noise levels
above 85 dBA is hazardous to hearing.
Wear ear protection when operating the generator
or when working nearby while it is operating.
24. Wear ANSI-approved safety glasses
and hearing protection during use.
25. People with pacemakers should consult their
physician(s) before use. Electromagnetic fields in
close proximity to a heart pacemaker could cause
pacemaker interference or pacemaker failure.
Caution is necessary when near the
engine’s magneto or recoil starter.
