Ⅶ. MAINTENANCE
7.9. Fuel Pipe/Blast Pipe Check
Fuel pipe/blast pipe are rubber products and are important components of
generators. They will age and become brittle with use. To prevent accidents and
property losses caused by aging of fuel pipe/blast pipe, please inspect them every
12 months or 300 hours. The fuel pipe/blast pipe inspection steps are as follows:
1.Loosen the cover and remove the right cover.
2.Turn the fuel switch knob to "ON" and the ventilation knob to "ON".
3.Observe whether there is any fuel leakage or damage in the fuel pipe ①.
4.Observe whether the blast pipe ② is damaged.
5.Reinstall the right cover and tighten the cover knob.
6.Turn the fuel switch knob to "OFF" and the ventilation knob to "OFF".
Notes:
1. Do not operate in places with high temperatures, smoke or flames.
2. The fuel pipe/blast pipe is damaged and needs to be changed in time.
3. Before replacing the fuel pipe, all the fuel must be drained.
38
Ⅶ. TRANSPORTATION
1.Do not transport the generator when it is hot. Transport the generator when it is
cool.
2.If short-term and short-distance transporting, do not let the gasoline leak out
from fuel tank during transportation.
3.If long-distance transporting, drain the gasoline and oil.
4.Do not connect the spark plug
5.When manually transport, only use the generator’s fixed handle to lift the
generator.
6.When transporting with vehicles, do not jolt the generator on rugged road. If had
to, drain the oil and gasoline in advance.
7.After transporting with vehicles, do not leave the generator in confined trunk.
The high temperature inside the confined trunk will cause evaporation of gasoline
and even cause explosion.
WARNING

Ⅸ. STORAGE
If you plan to store the generator for a long time, you need to complete some
protective measures to prevent aging, corrosion or accidents. Stop the generator
first. After the generator has fully cooled down, follow the following protective
measures:
1.Open the fuel tank cap, take out the fuel tank filter, pump the gasoline in the
tank into a special container, and replace the fuel tank filter and fuel tank cap.
2.Turn the engine switch to "RUN" and the fuel tank cap vent knob to "ON".
3.Remove the right cover.
4.Take out the oil drain pipe and use a container to collect it, loosen the carburetor
drain bolt, and drain all the fuel in the fuel tank.
5.After draining all the fuel in the fuel tank, tighten the carburetor drain bolt and
insert the carburetor drain pipe back into the fixing hole on the bottom plate of
the body.
6.Turn the fuel switch to "OFF" and the fuel tank cap vent knob to "OFF".
7.If the engine oil has been used for a long time, change new engine oil and
replace the right cover.
8.Remove the spark plug and pour about a spoonful of new oil into the engine.
9.Replace the spark plug and slowly pull the starter handle for a few minutes to
allow the engine oil to lubricate the box.
10.Slowly pull up the starting handle until you feel obvious resistance. At this time,
the intake valve and exhaust valve are closed, which helps to prevent internal rust.
11.Use a clean cotton cloth to wipe the surface of the generator, cover it in a bag,
and store it in a dry, cool and ventilated area.
