SAVE THESE WARNINGS
IMPORTANT SAFETY INFORMATION
1. 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.
2. If an appliance begins to operate abnormally, becomes sluggish or stops suddenly, turn it off immediately.
Disconnect the appliance, and determine whether the problem is the appliance, or if the rated load capacity
of the generator has been exceeded.
3. Make sure that the electrical rating of the tool or appliance does not exceed that of the generator. Never
exceed the maximum power rating of the generator. Power levels between rated and maximum may be
used for no more than 30 minutes.
4. Substantial overloading will open the circuit breaker. Exceeding the time limit for maximum power
operation or slightly overloading the generator may not switch the circuit breaker or circuit protector OFF,
but will shorten the service life of the generator.
1. Do not connect the Generator directly into a home’s utility electrical line. Do not plug this Generator into
an outlet in the home. Connecting a generator directly to a utility power supply can “back feed” along the
power lines and kill or injure utility workers working on the lines.
GENERATOR PRECAUTIONS:
2. All connections and conduits from the Generator to the load must only be installed by trained and licensed
electricians, and in compliance with all relevant local, state, and federal electrical codes and standards, and
other regulations where applicable.
3. The Generator must be earth-grounded in accordance with all relevant electrical codes and standards
before operation. A 10-gauge copper wire should be used to connect the ground terminal of the Generator
to a grounding rod. A wire that is too thin may not provide sufcient electrical current carrying capacity to
be an adequate ground path.
The other end of the ground wire must be securely fastened to an approved ground source. (See Figure
A.) Refer to local regulations for ground source information. If unsure of regulations or procedures, obtain
assistance from a licensed or certied electrician.
4. Insulate all connections and disconnected wires.
5. Connect the Generator only to a load or electrical
system (120 V~) that is compatible with the electrical
characteristics and rated capacities of the Generator.
6. Set up the Generator outdoors in a wellventilated,
dry area, away from building air intakes. The Generator
should be protected from direct exposure to rain and
snow. Do not set up the Generator on a conductive
surface such as a metal deck.

PRE-OPERATION INSPECTION
OPERATION
Generator OIL: a key factor in deciding the generator’s performance. Do not apply generator oil with additives
or 2-stroke gasoline oil, as they haven’t enough lubrication, which may shorten the generator’s service life.
1. Before adding fuel, make sure the generator is on a level, at surface equipment.
Generator oil recommended: SAE10W-30. As viscosity varies
with regions and temperatures, so the Lubricant has to be
selected in accordance with our recommendation.
2. Clean the top of the Dipstick and the area around it. Remove
the Dipstick and wipe it off with a clean, lint free rag.
3. Reinsert the Dipstick without threading it in and remove it to
check the oil level. The oil level should be up to the full level.
4. If the oil level is at or below the low mark add the appropriate
type of oil until the oil level is at the proper level. SAE 10W-30
oil is recommended for general use.
5. Thread the dipstick back in.
NOTICE: DO NOT run the generator with
too little oil. Generator will shut off if
generator oil level is too low.
BATTERY (only for 2GF-4, 2.5GF-4, 2.8GF-7: Check and
make sure the electrolyte level of each battery is between
the upper and lower lever markers.

AIR FILTER ELEMENT MAINTENANCE:
1. Wipe off the air cleaner cover. The air cleaner cover is held in place by clamps. Remove the clamps and
the cover.
2. Remove the air lter element.
3. Cleaning: A. There are two foam lter elements. Wash them in warm water and mild liquid soap several
times. Rinse. Squeeze out excess water and allow it to dry completely. B. Soak the lter in lightweight oil
briey, then squeeze out the excess oil.
4. Install the new lter or the cleaned lter. Secure the Air Cleaner Cover before use. Gasket-style: Finger-
tighten until the gasket contacts the cylinder head, then about 1/2-2/3 turn more. Non-gasket-style: Finger-
tighten until the plug contacts the head, then about 1/16 turn more.
5. Apply dielectric spark plug boot protector (not included) to the end of the spark plug and reattach the wire
securely.

OPERATION
1. Push the fuel switch to “ON”.
STARTING THE GENERATOR
2. Push the chock lever to “OFF”. 3. Move left the throttle lever a little.
4. Start the generator. ROPE HANDLE STARTER: Push the generator switch to “ON”. Pull slightly the
starting rope handle up until feeling anti-action, and then make a rapid pull. Releasing the handle suddenly
may make it hitting the generator. Release the handle slowly conforming to its recoiling force.
ELECTRIC STARTER: Push the generator switch to “START” and remain
there until the generator Start.
CAUTION: Use the generator switch not more than 5 second each time to
avoid damage of the generator. Try once more 10 second later after last
attempt failures. Once the generator starts, reset the generator switch to
“ON”.
1. Preheat the generator and push back the 2.
Set the throttle lever in proper position to ensure
choke lever to “ON”.
2. Set the throttle lever in proper position to ensure
choke lever to the generator runs at required
velocity.

OPERATION
Generator Oil Alarm: The generator oil alarm is designed to alarm the user the fact that the generator oil
in the crankcase in insufcient. Run with insufcient generator oil may damage the generator. Once oil level
in the crankcase is too low, the generator oil alarm will stall the generator automatically to make it free of
damage while the generator switch is still at “ON”.
CAUTION: If the generator still fails to work, check the generator oil level rst before go to other check items.
Breaker (Electric Start): The Breaker is used to protect the battery
charging circuit. It will be disconnection when short circuit or battery
polarity connects in wrong direction. Check items.
The green indicator would be light once the circuit off. If this happens,
please nd out the reason and solve it then press the button to recover
the breaker.
In higher elevations, the standard mixture ratio is relatively too big so the generator performance may be
impaired while the fuel consumption may increase. This problem can be solved as follows: replace the main
jet of carburetor with a smaller one, then, adjust the idly screw. If always using on highlands with a height
above sea level of 1830 meters, ask your dealer for doing the job. The generator power will decrease by
about 3.5% with every 305 meters up in height; even the proper main jet is used. The output would be much
lower if not adjust the jet.
CAUTION: The generator equipped with the main jet applicable to high altitudes may be damaged seriously
in area below specied altitude, because its mixture ratio is too thin, output drops and the generator overheats
for operation in low altitude area. In the case, ask your dealer to recover the generator to its normal technical
status.
STOPPING THE GENERATOR
1. Push right the throttle valve
lever to the bottom
2. Push the generator switch to
“OFF”
3. Set the fuel switch to “OFF”
With the generator running, carbon monoxide, oxide of nitrogen and hydrocarbon will produce, and in certain
conditions, oxide of nitrogen and hydrocarbon will react chemically each other to make smoke while carbon
monoxide is toxic, so exhaust control of them is very important. The company decreases the exhaust emissions
by introducing poor-fuel carburetors and other devices into the generator to solve the problem.
EXHAUST CONTROL SYSTEM
Maintain the generator periodically in accordance with the Maintenance Schedule in the manual. The
maintenance schedule is made out on the base of normal use in normal conditions, if using under heavy load,
dusty or wet circumstances or in high temperature, more frequents maintenance will be necessary.
We recommend that you should choose such parts, which are manufactured by XTREMEPOWERUS or
equivalent to these in quality as replacement ones. Replacement without so high quality may impair the
exhaust control system in effectiveness.
