Operation and Use Questions

Call Customer Service at 1-888-331-4569 with questions
or concerns about equipment operation and mainte-

Before Starting Engine

1. Verify engine oil level is correct.
2. Verify fuel level is correct.
3. Verify unit is secure on level ground, with proper
clearance and is in a well ventilated area.

Prepare Generator for Use

DANGER: Asphyxiation. Running engines pro-
duce carbon monoxide, a colorless, odorless,
poisonous gas. Carbon monoxide, if not
avoided, will result in death or serious injury.
DANGER: Asphyxiation. The exhaust system
must be properly maintained. Do not alter or
modify the exhaust system as to render it
unsafe or make it noncompliant with local
codes and/or standards. Failure to do so will
result in death or serious injury. (000179b)
WARNING: Risk of fire. Do not use generator
without spark arrestor installed. Failure to do
so could result in death or serious injury.
WARNING: Asphyxiation. Always use a battery
operated carbon monoxide alarm indoors and
installed according to the manufacturer's
instructions. Failure to do so could result in
death or serious injury. (000178a)
WARNING: Risk of Fire. Hot surfaces could ignite
combustibles, resulting in fire. Fire could result
in death or serious injury. (000110)
Hot surfaces. When operating
machine, do not touch hot surfaces. Keep
machine away from combustibles during use.
Hot surfaces could result in severe burns or fire.
CAUTION: Equipment and property damage.
Disconnect electrical loads prior to starting or
stopping unit. Failure to do so could result in
equipment and property damage. (000136)
Grounding the Generator When In
I. The generator is equipped with an equipment
ground connecting the generator frame and the ground
terminals on the AC output outlets (see NEC 250.34 (A).
This allows the generator to be used as a portable with-
out grounding the frame of the generator as specified in
NEC 250.34.
• Neutral Floating
Fig. I
The generator (stator winding) is isolated from the frame
and from the AC outlet ground pin. Electrical devices
that require a grounded outlet pin connection will not
function if the outlet ground pin is not functional.

Know Generator Limits

Overloading a generator can result in damage to the
generator and connected electrical devices. Observe the
following to prevent overload:
• Add up the total wattage of all electrical devices to be
connected at one time. This total should NOT be greater
than the generator's wattage capacity.
• The rated wattage of lights can be taken from light
bulbs. The rated wattage of tools, appliances, and
motors can be found on a data label or decal affixed to
the device.
• If the appliance, tool, or motor does not give wattage,
multiply volts times ampere rating to determine watts
(volts x amps = watts).
• Some electric motors, such as induction types, require
about three times more watts of power for starting than
for running. This surge of power lasts only a few seconds
when starting such motors. Make sure to allow for high
starting wattage when selecting electrical devices to
connect to the generator:
1. Figure the watts needed to start the largest motor.
2. Add to that figure the running watts of all other
connected loads.
