GENERATOR SAFETY WARNINGS
DANGER: CARBON MONOXIDE
Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbonmonox-
ide (CO). This is a poison gas you cannot see or smell. If you can smell the generator exhaust, youare
breathing CO.But even if you cannot smellthe 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 inthese areas. Using a fan or opening windows and doorsdoes
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 youuse a generator correctly, COmay leak into the home. ALWAYS use a battery-powered or
battery-backupCOalarm inthe home.If you start to feel sick, dizzy, or weak after the generator has
been running, move to freshair RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.

CONNECTING ELECTRICAL DEVICES
CAUTION: Before connecting devices, become familiar with the markingsonthe control panel before
connecting electrical devices. The 120V AC receptacles are for connecting electrical devices that runon
120V, 60 Hz,single phase, AC current. DO NOT connect 50Hz or 3-phase loadsto the generator.
Followthe steps below to properly connect your device(s) to the generator:
1. Before connecting electrical devices, allow the generator to run for a few minutes to stabilize the speed
andvoltage output.
2. Select the device with the highest wattage, and make sure it is turned off.Plug the device into the genera-
tor and thenturn the device on. Allow the engine to stabilize.
3. Repeat step 2 to plug in each additional device. DO NOT attempt to plug in or start multiple devices at the
same time.
PARALLEL OPERATION
The parallel operation outlets (Fig. 2) allow you to connect two
AIPOWER generators to increase the total available electrical power.
The AIPOWER Parallel Operation Kit can be purchased. Follow the
instructions included with your parallel operation kit for proper
installation and operation.
LOW IDLE SWITCH
This generator is equipped with an LOW IDLE Switch (Fig. 1).
Engaging this switch allows the system to regulate the engine
speed and automatically adjust its fuel consumption to match the
required load. When the electrical load changes, the generator
engine will automatically speed up and slow down as needed.
This reduces fuel consumption and noise levels, while extending
runtime and engine’s lifespan.
CIRCUITBREAKERS
The circuit breakers (Fig. 3) protect the individual AC and DC
circuits. The circuit breaker will activate when the outlets exceed.
When the circuit breaker activates, turn off and disconnect the
device from its respective outlet, and press the circuit breaker to
reset.
Fig. 1
Fig. 2
Fig. 3
Keep this switch engaged ONLY when the power load requirement is LESS THAN 75% of the rated watts.
Do not engage the switch when the total load is more than 75% of the rated watts.The generator engine
must run at full speed to supply power for anything over 75% of the rated watts.
14

KNOW YOUR GENERATOR
Select the items you will power at the same time.1. Total the running (rated) watts of these items. This is the amount of power the generator must produce
to keep the items running.
2.
Estimate how many starting (max.) watts you will need. Sarting wattage is the short burst of power
needed to start electric motor-driven tools or appliances such as a circular saw or refrigerator. Because
not all motors start at the same time, total starting (max.) watts can be estimated by adding only the
item(s) with the highest additional starting (max.) to the total rated watts.
3.
GENERATOR CAPACITY
Make sure the generator can supply enough running (rated) and starting (max.) watts for the items you will
power at the same time. Follow these simple steps.

With nothing connected to the generator, start the engine as described later in this manual.1.
To prolong the life of the generator and attached devices, it is important to take care when adding electrical
loads to the generator. There should be nothing connected to the generator outlets before starting its
engine. The correct and safe way to manage generator power is to sequentially add loads as follows:
NOTICE:
Plug in and turn on the rst load, preferably the largest load you have.2. Permit the generator output to stabilize (engine runs smoothly and attached device operates properly).3. Plug in and turn on the next load.4. Again, permit the generator to stabilize.5. Repeat steps 4 and 5 for each additional load.6.
Never add more loads than the generator capacity. Take special care to consider surge loads in generator
capacity as previously described.
Do not overload the generator’s capacity. Exceeding the generator’s wattage/amperage capacity may
damage the generator and/or electrical devices connected to it.

GENERATOR PREPARATION
The following section describes the necessary steps to prepare the generator for use. Failure to perform these
steps properly can damage the generator or shorten its life.
STEP 1 - ADD/CHECK OIL
The generator is shipped without oil. User must add the proper amount of oil before operating the generator
for the first time. The oil capacity of the engine crankcase is20.2 fl. oz. (0.6 L).
To add oil,followthese steps:
1. Place the generator on a level surface.Make sure the engine is
OFF before adding or checkingoil.
2. Unscrew the oil access cover knob, and remove the cover
from the side panel (Fig. 4). Unscrewthe oil dipstick from the
engine.
3. Using an oil funnel or appropriate dispenser, slowly add oil into
the oil fill (Fig. 5), being careful not to overfill the unit. Fill the
Fig. 4
crankcase to the upper fill line so you can visually see the oil
cominghalfway upthe oil fill threads (Fig. 6).
4. Reinstall the oil dipstick and firmly tighten it. Wipe clean any
spilled oil.
5. Reinstall the oil access cover.Turn the oil access cover knob to
the lockedposition to secure the cover in place.
CAUTION: Keep the generator level! Tilting the generator to
assist in fillingwill cause oil to flow into the wrong areasof
the engine and cause damage.

To check oil level (beforeevery subsequent start):
1.Place the generatoron a level surface. Makesurethe engine is OFF
before adding or checking oil.
2. Open the oil access cover. Remove and wipe the dipstick with a
clean rag.
3. Insert the dipstick into the oil fill without screwing it in. Remove the
dipstick to check the oil mark (Fig.7).
If the oil mark covers less than one half of the dipstick,slowly add oil
until the oil mark reaches to the top of the dipstick (or when you can
see the oil coming halfway upthe oil fill threads).
4. Wipe clean any oil leaks and firmly tighten the dipstick. Reinstall
the oil access cover.
STEP 2 - ADD/CHECK FUEL
GASOLINE WARNING: Keepgenerator away from open flame. This generator may emit highly
flammable and explosive gasoline vapors, which can cause severe burns or even death if ignited. A
nearby openflame can leadto explosioneven if not directly in contact with gasoline.
• Do not operate near open flame,heat, or any other ignition source.
• Do not smoke near the generator.
• Always operate ona firm,levelsurface.
• Always turn generator off before refueling. Allow generator to coolfor at least 2minutes before re-
moving the fuel cap. Loosen cap slowly to relieve pressure in tank.
• Do not overfill fuel tank. Fuel may expand during operation. Do not fill to the top of the tank. Allow for
expansion.
• Always check for spilled fuelbefore operating. Clean up any spilled fuel before starting.
• Empty fuel tank before storing or transportingthe generator to prevent spilling.
Use ONLY fresh(within 30 days from purchase),lead-free gasoline with a minimum of 87octane rating.
The generator performs best with ethanol-free gasoline. DO NOT use gasoline withover 10% ethanol.
The capacity of the fuel tank is 2.6 US gallons (10.0 L). DO NOT mix oil with gasoline.
NOTICE:
•Never use anoil/gasoline mixture.
•Never use old gasoline.
•Keep gasoline away from sparks,open flames, pilot lights, heat and other sources of ignition.
• Avoid getting dirt or water into the fuel tank.
•Gasoline can age in the tank andmake starting difficult.Never
store generator for more than 2 months withfuelinthe tank.

To add gasoline, follow these steps:
1. Make sure the generator is shut OFF and on a level
surface.Unscrew the fuel cap (Fig.8) and set it aside.The
fuel cap may be tight andhard to unscrew.
2.Slowly add unleaded gasoline to the fuel tank.Be care-
ful not to overfill.
NOTE: Do not fill the fuel tank to the very top.If you do so,
gasoline will expand and spill during use, even with the
fuel cap inplace.
3. Reinstall fuel cap and wipe clean any spilled gasoline
with a dry cloth.
To check fuel level:
During operation, the fuel level will be displayed on the DATA CENTER of the panel, or check the fuel gauge.
If the fuel level is low, refill the fuel tank before starting your generator for the next time.

STEP 3 - GROUND THE GENERATOR
To reduce the risk of electric shock and to maximize safety, the
generator should be properly grounded.
Ground the generator by tightening the grounding nut on the front
control panel (Fig. 9) against a grounding wire. A generally
acceptable grounding wire is a No. 12 AWG (American Wire
Gauge) stranded copper wire.
This grounding wire should be connected at the other end to a
copper, brass, or steel grounding rod that is driven into the earth.
Wire and grounding rods are not included with the generator.
Grounding Nut
WARNING: Failure to properly ground the generator increases your risk of electric shock.
