EXHAUST FUMES ARE POISONOUS
Never operate the engine in a closed area or it may cause unconsciousness and death within a short time.
Operate the engine in a well ventilated area.
FUEL IS HIGHLY FLAMMABLE AND POISONOUS
Always turn off the engine when refueling.

ENGINE AND MUFFLER MAY BE HOT
Place the machine in a place where pedestrians or children are not likely to touch the machine.
Avoid placing any flammable materials near the exhaust outlet during operation.
The machine must be kept away from the buildings and other equipments at least one meter, for it may be
ELECTRIC SHOCK PREVENTION
Never operate the engine in rain or snow.
Never touch the machine with wet hands or electrical shock will occur.
Be sure to ground (earth) the generator.
Use ground (earth) lead of sufficient current capacity.
Avoid connecting the generator to commercial power outlet.
Avoid connecting the generator in parallel with any other generator.

The engine switch controls the ignition system.
Ignition circuit is switched on.
The engine can be started.
Ignition circuit is switched off.
The engine will not run.
AC BREAKER (N.F.B)
The AC breaker turns off automatically when the load exceeds the generator rated output.Press the reset button to
reset the protector.
Reduce the load to within specified generator rated output if the AC breaker (N.F.B) turns off.
DC BREAKER (N.F.B)
The DC breaker turns off automatically when the load exceeds the generator rated output.
Pre-operation checks should be made each time when the generator is used.
The engine and muffler will be very hot after the engine has been run. Avoid touching the engine and muffler
while they are still hot with any part of your body or clothing during inspection or repair.
Make sure there is sufficient fuel in the tank.
Use oil-mixed gasoline ,or engine will be overheated.Gasoline and oil mixing ration is 50:1 or 40:1(in the
Use clean,fresh,regular unleaded gasoline with a minimum of 77 octane.
Use special purpose oil for 2-stroke.
Recommended fuel: Oil-mixed gasoline
Fuel tank capacity: 4.2L
Fuel is highly flammable. Check “ SAFETY INFORMATION” carefully before refueling.
Do not fill above the top of the fuel fill or it may overflow when the fuel heats up later and expands.Add fuel
until level is approximately 1 inch from top of fuel fill.
After refueling, make sure the tank cap is tightened securely.
Make sure to ground the generator.
The battery(12V) is charged when the engine is running.
Battery electrolyte is poisonous and dangerous,causing severe burns,etc.It contains sulfuric
acid.Avoid contacting with skin,eyes or clothing.
Battery produce explosive gases.Keep sparks,flame,cigarettes,etc.away.Ventilate when charging or using in closed
space.Always cover eyes when working near batteries.Keep out of reach of children.
STARTING THE ENGINE
Before starting the engine, do not connect the electric apparatus.
Turn the fuel cock lever to “ON”.
Turn the engine switch to “ON”.
Turn the choke lever to the
position. The choke is not required to start a warm engine.
Pull slowly on the recoil starter until it is engaged, then pull it briskly. Take your hand off the recoil starter
immediately after the engine starts.
Warm up the engine. Move choke lever toward the operating position a short distance at a time over several
seconds in warm weather or minutes in cold weather. Let engine run smoothly before each change.
Turn the choke lever back to the operating position.
Be sure the electric apparatus is turned off before plugging in.
Be sure the total load is within generator rated output.
Be sure the socket load current is within socket rated current.
Wind the power lead 2 or 3 turns around frame.
Start the engine.
Plug into AC socket.
Make sure the pilot light is on.
Turn on the electric apparatus.
Reduce the load to within specified generator rated output if the AC breaker (N.F.B.) turns off.
Battery charging(if equipped).
Red lead to positive(+),black to negative(-).
This battery charging system is intended to recharge weak batteries,not to “BOOST START” vehicles.Before
charging a storage battery,please read the battery in the user’s manual.
STOPPING THE ENGINE.
Turn off the electric apparatus.
Disconnect the electric apparatus.
Turn the engine switch to “OFF”.
Turn the fuel cock lever to “OFF”.
Regular maintenance is most important for the best performance and safe operation.
Check condition adjust

Check for leakage
Retighten or replace
gasket if necessary
Check muffler screen.
Check fan damage.
Clean more frequently
Check all fittings
and fasteners correct if
Do not wring out the element. This could cause it to tear.
Be sure the element sealing surface matches the air filter so there is no air leak.
The engine should never run without the element sealing, excessive piston and or cylinder wear may result.
Never refuel while smoke or in the vicinity of an open flame.
SPARK PLUG INSPECTION
Standard electrode color
Spark Plug Gap:0.7-0.8mm(0.028-0.031in)
FUEL TANK FILTER
Clean with solvent.
Be sure the tank cap is tightened securely.
ENGINE WON’ T START
1. Fuel systems
No fuel supplied to combustion chamber.
No fuel in tank…Supply fuel.
Clogged fuel line
Clean fuel line.
Foreign matter in fuel cock
Clean fuel cock.
2. Electrical systems
Spark plug dirty with carbon or wet
Remove carbon or wipe spark plug insufficient.
Faulty ignition system
Worn out piston and cylinder
Loose cylinder head nuts
Tighten nuts properly.
Long term storage of your machine will require some preventive procedures to guard against deterioration.
DRAIN THE FUEL
