SAFETY ALERT SYMBOL
DANGER: This generator produces poisonous carbon monoxide gas when running. This
gas is both odorless and colorless. Even if you do not see or smell gas, carbon monoxide
may still be present. Breathing this poison can lead to headaches, dizziness, drowsiness,
and eventually death.
●Use outdoors ONLY in non-conned areas.
●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
which heat during use.
The safety alert symbol is used with one of the safety words (DANGER,
CAUTION, or WARNING) to alert you of hazards. Please pay attention to
these hazard notices both in this manual and on the generator.
GENERAL SAFETY PROCEDURES
7
Please familiarize yourself with the following safety symbols and words:
●DANGER: Indicates a hazard that will result in serious injury or death if instructions are not
followed.
●WARNING: Indicates a strong possibility of causing serious injury or death if instructions are not
followed.
●CAUTION: Indicates a possibility of personal injury or equipment damage if instructions are not
followed.

WARNING: This generator may emit highly ammable and explosive gasoline vapors,
which can cause severe burns or even death. A nearby open ame can lead to an
explosion even if not directly in contact with gas.
●Do not operate near an open ame.
●Do not smoke near generator.
●Always operate on a rm, level surface.
●Always turn generator o before refueling.
●Allow generator to cool for at least 2 minutes before removing fuel cap. Loosen cap
slowly to relieve pressure in tank.
●Do not overll gas tank. Gas may expand during operation. Do not ll to the top of
the tank.
●Always check for spilled gas before operating.
●Empty the gasoline tank before storing or transporting the generator.
●Before transporting, turn fuel valve to the o position and disconnect the spark plug.
WARNING: This generator produces a powerful voltage, which can result in electrocution.
●ALWAYS ground the generator before using it (see the “Grounding the Generator”
portion of the “PREPARlNG THE GENERATOR FOR USE section).
●Generator should only be plugged into electrical devices, either directly or with 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.
●Use a ground fault circuit interrupter (GFCI) in highly conductive areas such as metal
decking or steel work. GFCls are available in-line with some extension cords.
●Do not use uncovered in rainy or wet conditions.
●Do not touch bare wires or receptacles (outlets).
●Do not allow children or non-qualied persons to operate.

GENERATOR SETUP (CONTINUED)
Add oil
The generator requires engine oil to operate properly. The generator, when new from the package
contains no oil in the crankcase*. You must add the proper amount of oil before operating the
generator for the rst time. This amount is equal to the oil capacity of the engine crankcase:
WARNING: Do not apply engine oils with additives or 2-stroke gasoline engine oils. They don’t
have enough lubrication, and may shorten the engine’s service life.
a. Make sure the generator is on a level surface.
b. Unscrew the oil ller/dipstick cap from the engine .
c. Using a funnel, add the appropriate amount of oil
into the crankcase. You will know the crankcase is
full when the oil level has reached the lower lip of
the opening you have just poured the oil into.
d. Replace oil ller cap.
1.
Step 3 - Adding Oil
Engine oil recommended: SAE 10W-30. Viscosity varies with
regions and temperatures. Choose your oil viscosity using the
chart to the left.
* A small amount of oil from factory testing may be present on
arrival.
Model Number XP10000EH
Engine Oil Capacity 37 . oz (1.1L)

WARNING: DO NOT overll the crankcase. This
may damage the motor and shorting overall life
of your generator.
