1.1 OPERATOR ATTENTION
Read and understand this manual before operating the
generator.
Place the generator in a place where pedestrians, children and
pets are not likely to touch. Do not let children operate the
generator.
Turn OFF the Fuel Tap before tilting the generator.
The generator is allowed to be
tilted down, but ONLY lay on the
Drawbar Side, and only after
stopping the engine. If lay down on
other side, OIL may leak and
damage the engine or your
property. Also FUEL may leak and
cause FIRE or an EXPLOSION.

- 7 -
DO NOT remove any cover of the generator
case when the engine is running.

Exhaust fumes contains poisonous carbon monoxide（CO）, a
colorless and odorless gas. Breathing CO can cause loss of
consciousness and may lead to death.
Never run your generator inside a garage or house, even if
door or window is open. Operate the generator in a
well-ventilated area.

- 8 -
1.3 ELECTRIC SHOCK HAZARDS
Never operate the engine in rain, snow or wet locations.
Never touch the machine with wet hands.
Ground unit to avoid electrical hazards.
1.4 FIRE AND BURN HAZARDS
Petrol is extremely flammable and explosive under certain
conditions. Do not smoke or allow flames or sparks where the
generator is refueled or where petrol is stored. Refuel in a
well-ventilated area with the engine stopped and cooled.
The generator is allowed to be tilted down, but ONLY lay down

4. PREPARATION
4.1 ENGINE OIL
NOTE
The engine has been shipped from our factory without oil. Put
oil before starting.
Recommended engine oil: 4-stroke engine oil, SAE 10W-40.
Engine oil quantity: 0.35L.

- 15 -
Add Engine Oil:
(1). Open the Oil Maintenance Cover 1, and remove the Oil Cap 2.
(2). Fill the specified amount of the recommended engine oil, and then
install and tighten the Oil Cap.
NOTE
Make certain the generator is on a flat, level surface.
Keep the engine oil level between LOWER LIMIT and UPPER
LIMIT. Too much or too little oil will shorten the service life of
the engine.
The engine is equipped with a low oil sensor that will prevent
the engine from running. If the oil level falls below a critical
threshold, the engine will stop automatically.
When the engine shuts down automatically by the low oil
protection, the LOW OIL LEVEL LED (yellow) will come on, and
unless you refill with oil, the engine will not start again.

4.2 FUEL
Petrol is extremely flammable and explosive under certain
conditions. Do not smoke or allow flames or sparks where the
generator is refueled or where petrol is stored.
Refuel in a well-ventilated area with the engine stopped.
DO NOT fill above the Red Level , otherwise it may
overflow when the fuel warms up and expands.
Immediately wipe off spilled fuel with a clean, dry, soft cloth,
since fuel may deteriorate painted surfaces or plastic parts.
Add Fuel:
(1). Remove the Fuel Cap (1) and fill the fuel into the tank up to the Red
Level 2.
(2). The fuel level in the fuel tank can be checked through the Fuel
Gauge 3.
(3). After fill the fuel, make sure the Fuel Cap (1) is tightened securely.
NOTE
Use only unleaded petrol (91). The use of leaded petrol will
cause severe damage to internal engine parts.
Never use an oil/petrol mixture.

5. STARTING THE ENGINE

- 18 -
5.1 CHECK ENGINE OIL
Check the oil BEFORE EACH USE with the generator on a level
surface and with the engine stopped.
RECOMMENDED OIL:
4-stroke engine oil, SAE 10W-40.
(1). Open the Oil Maintenance Cover (1).
(2). Remove the Oil Cap (2) and wipe the Dipstick (3) clean.
(3). Check the oil level by inserting the Dipstick (3) into the filler neck
without screwing it in.
(4). If the wet line on the Dipstick (3) is between "L" position and "H"
position, the oil level is OK. If the oil cannot reach "L" position, the oil
level is too low. Fill to the upper limit of the oil filler neck with the
recommended oil.
(5). Tighten the Oil Cap (2) and reinstall the Oil Maintenance Cover (1).
(6). Check generator for oil leakage.
NOTE
Make certain the generator is on a flat, level surface when
check the engine oil.
Engine oil quantity: 0.35L.
The engine is equipped with a low oil sensor that will stop the
engine automatically when the oil level falls below a critical
threshold.
When the engine shuts down automatically by the low oil
protection, the LOW OIL LEVEL LED (yellow) will come on, and
unless you refill with oil, the engine will not start again.

5.2 CHECK FUEL
Do not smoke or allow flames or sparks where the generator is
refueled or where petrol is stored.
Refuel in a well-ventilated area with the engine stopped.
DO NOT fill above the Red Level.
Check the fuel BEFORE EACH USE with the generator on a level
surface and the engine stopped.
(1). Checked the fuel level in the fuel tank through the Fuel Gauge (1). If
the red mark in the Fuel Gauge (1) is close to "E" position, means the
fuel level in the fuel tank is lower. If the red mark in the Fuel Gauge (1) is
close to "F" position, means the fuel level in the fuel tank is higher.
(2). Refuel if necessary.
(3). After fill the fuel, make sure the Fuel Cap is tightened securely.
(4). Check generator for fuel leakage.
NOTE
Use only unleaded petrol (91).
Never use an oil/Petrol mixture.
Fuel tank capacity: 4.2L.
Make certain the generator is on a flat, level surface when
check the fuel.
