spills on your skin or clothing, immediately wash with soap and water and change your clothes.
When operating or transporting the machine, be sure it is kept upright. If it tilts, fuel may leak from the carburetor or
fuel tank.
3）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.
Keep the machine at least 1 m ( 3 ft ) from buildings or other equipment, or the engine may overheat.
Avoid operating the engine with a dust cover.
4）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.
NOTE: ───────────────
Use ground (earth) lead of sufficient current capacity.

warm.
4.Pull the starter handle slowly until resistance is felt. This is the “Compression”
point. Return the handle to its original position and pull swiftly. Do not fully pull
out the rope. After starting, allow the starter handle to return to its original
position while still holding the handle.
5.Warm up the engine.
6.Turn the choke lever back to the operating position.
7.Warm up the engine without a load for a few minutes.

3）STOPPING THE ENGINE
1. Turn off the power switch of the electric apparatus or unplug the cord
from receptacle of the generator. Turn the AC switch to “OFF”.
2. Turn the engine switch to “OFF”.
3. Turn the fuel cock lever to “OFF”.
4）BATTERY
(for electric starting system)
1. REPLENISHING THE BATTERY FLUID
Check the fluid level. The level should be between the upper and lower
level marks.
Add only distilled water if necessary.
2. BATTERY STORE
Remove the battery and charge it. Store it in a dry place and recharge it once a
month. Do not store the battery in an excessively warm or cold place.
3. RECOMMENDED BATTERY
Recommended battery: 12V/26A·h
NOTE: ──────────────────────
Clamp the red wire to the positive (+) terminal and the black wire to the
negative (-) terminal of the battery. Do not reverse these positions.
Be sure the battery is installed on the battery mount tray securely
──────────────────────────
NOTE: ──────────────────────
In order to increase the longevity of your generator it is advantageous to
maintain a minimum load of approximately one third the rated output.

2）ENGINE OIL REPLACEMENT
1. Place the machine on a level surface and warm up the engine for several
minutes. Then stop the engine.
2. Remove the oil filler cap
3. Place an oil pan under the engine. Remove the oil drain plug so that the
oil can be completely drained.
4. Check the oil drain plug, gasket, oil filler cap and O-ring. If damaged
replace.
5. Reinstall the oil drain plug.
6. Add engine oil to the upper level.
Recommended engine oil:

2. After wetting the element by clean engine oil, squeeze it tight by hand.
3. Lastly, put the element in the case and install it securely.
CAUTION: ───────────────
The engine should never run without the element; excessive piston and/or
cylinder wear may result.
