Connection of the product to a building’s electrical
system is not applicable.

Never use the generator in a location that is wet or damp. Never expose the inverter to rain,
snow, water spray or standing water while in use. Protect the inverter from all hazardous
weather conditions. Moisture or ice can cause a short circuit or other malfunction in the
electrical circuit.
Never operate the generator in an enclosed area. Engine exhaust contains carbon monoxide.
Only operate the generator outside and away from windows, doors and vents.
Voltage produced by the generator could result in death or serious injury.
· Never operate the generator in rain or a flood plain unless proper precautions are taken to
avoid being subject to rain or a flood.
· Never use worn or damaged extension cords.
· Always have a licensed electrician connect the inverter to the utility circuit.
· Never touch an operating generator if the generator is wet or if you have wet hands.
· Never operate the generator in highly conductive areas such as around metal decking or steel
works.
· Always use grounded extension cords. Always use three-wire or double-insulated power tools.
· Never touch live terminals or bare wires while the generator is operating.
· Be sure the generator is properly grounded before operating.

Carbon Monoxide Specification
CO DETECT technology monitors the accumulation of
carbon monoxide (CO), a poisonous gas produced by
engine exhaust when the generator is running. If CO
Sensor detects unsafe elevated levels of CO gas, it
automatically shuts off the engine. CO Sensor is not a
substitute for an indoor carbon monoxide alarm or for
safe operation. DO NOT allow engine exhaust fumes to
enter a confined area through windows, doors, vents or
other openings. Generators must ALWAYS be used
outdoors, far away from occupied buildings with engine
exhaust pointed away from people and buildings. Meets
the requirements of ANSI/PGMA G300-2018.

Never refuel the generator while the
engine is running.
1. Shut off the generator.
2. Allow the generator to cool down so all surface
areas of the muffler and engine are cool to the touch.
3. Move the generator to a flat surface.
4. Clean area around the fuel cap.
5. Remove the fuel cap by rotating counterclockwise.

Recoil Starter
Electric starting
For proper starting and operation of the generator,
make sure you review the generator features and their
descriptions starting on page 8.
Before attempting to start the generator, verify the
following:
· The engine is filled with engine oil (see Figure 4:
Engine Oil Correct Level on page 13).
· The generator is situated in a proper location (see
Location Selection on page 11).
· The generator is on a dry surface (see Weather and
Dry Surface on page 11).
· All loads are disconnected from the generator (see
No Connected Loads on page 11).
· The generator is properly grounded (see Grounding
the Generator on page 11).
1. Remove all the loads out of the output.
2. Turn the fuel valve to the "ON" position.
3. Turn the choke lever to the"CLOSED" position.
NOTICE: Don't close the choke when starting the
engine in warm state.
4. Pull the starter grip until compression is felt, then
pull briskly (see Figure 6).
5. Turn the choke lever to the "OPEN" position after
the engine is warm.
Figure 6: Pull the Recoil Handle out from Generator
1. Remove all the loads out of the output.
2. Turn the fuel valve to the "ON" position.
3. Turn the choke lever to the"CLOSED" position.
NOTICE: Don't close the choke when starting the
engine in warm state.
4. Turn the generator switch to “START” position.
5. Turn the choke lever to the "OPEN" position after
the engine is warm.
1. Turn the AC circuit breaker to the “OFF” position.
2. Turn the generator switch to the “OFF” position.
3. Turn the fuel valve to the “OFF” position.
During normal operation, use the following steps to
stop your generator:

Fuel use and switching
1. When the fuel switch is turned to Petrol, follow the
starting operation steps to normal use. When the fuel
switch is turned off, the engine stops and flameout.
2. When the fuel switch is turned to Gas, follow the
starting operation steps to normal use. When the fuel
switch is turned off, the engine stops and flameout.
3. When the generator runs normally, it needs to
switch from fuel oil to gas (or gas to fuel oil), and the
generator must be rapidly rotated to petrol or gas in no-
load state before it can be loaded and used normally.

BEFORE PERFORMING MAINTENANCE ON THE GENERATOR, REVIEW
THE SAFETY SECTION STARTING ON PAGE 5, AS WELL AS THE
FOLLOWING SAFETY MESSAGES.
Avoid accidentally starting the
generator during maintenance by
removing the spark plug boot from the
spark plug. For electric start generator,
also disconnect the battery cables
from the battery (disconnect the black
negative (-) cable first) and place the
cables away from the battery posts to
avoid arcing.
Following the maintenance schedule is important to keep the generator in good operating condition. The following
is a summary of maintenance items by periodic maintenance intervals.
Failure to perform periodic
maintenance or not following
maintenance procedures can cause
the generator to malfunction and could
result in death or serious injury.
Periodic maintenance intervals vary depending on
generator operating conditions. Operating the
generator under severe conditions, such as
sustained high-load, high-temperature, or unusually
wet or dusty environments, will require more
frequent periodic maintenance. The intervals listed
in the maintenance schedule should be treated only
as a general guideline.

1. Always operate or maintain the generator on a flat
surface.
2. Stop engine if running.
3. Let engine sit and cool for several minutes (allow
crankcase pressure to equalize).
4. Find the oil plug.
5. With a damp rag, clean around the oil fill/drain
plug.
6. Remove the oil fill/drain plug.
7. Check oil level: When checking the engine oil,
remove the oil fill/ drain plug.
Engine oil must always be checked and added when
the generator is on a flat, level surface, or an
inaccurate reading may result, causing serious
engine damage.
1. Always operate or maintain the generator on a flat
surface.
2. Stop engine if running.
3. Let engine sit and cool for several minutes (allow
crankcase pressure to equalize).
4. Find the oil plug.
5. Thoroughly clean around the oil fill/drain plug.
6. Remove the oil fill/drain plug.
7. Select the proper engine oil as specified in Figure
8.
8. Using the supplied oil funnel, slowly add engine oil
to the engine. Stop frequently to check the oil level
and avoid overfilling.
