PRE-OPERATION INSPECTION
OPERATION
Generator OIL: a key factor in deciding the generator’s performance. Do not apply generator oil with additives 
or 2-stroke gasoline oil, as they haven’t enough lubrication, which may shorten the generator’s service life.
1. Before adding fuel, make sure the generator is on a level, at surface equipment.
Generator oil recommended: SAE10W-30. As viscosity varies 
with regions and temperatures, so the Lubricant has to be 
selected in accordance with our recommendation.
2. Clean the top of the Dipstick and the area around it. Remove 
the Dipstick and wipe it off with a clean, lint free rag.
3. Reinsert the Dipstick without threading it in and remove it to 
check the oil level. The oil level should be up to the full level. 
4. If the oil level is at or below the low mark add the appropriate 
type of oil until the oil level is at the proper level. SAE 10W-30 
oil is recommended for general use.
5. Thread the dipstick back in.
NOTICE: DO NOT run the generator with 
too little oil. Generator will shut off if 
generator oil level is too low.
BATTERY (only for 2GF-4, 2.5GF-4, 2.8GF-7: Check and

AIR FILTER ELEMENT MAINTENANCE:
1. Wipe off the air cleaner cover. The air cleaner cover is held in place by clamps. Remove the clamps and
the cover.
2. Remove the air lter element.
3. Cleaning: A. There are two foam lter elements. Wash them in warm water and mild liquid soap several 
times. Rinse. Squeeze out excess water and allow it to dry completely. B. Soak the lter in lightweight oil
briey, then squeeze out the excess oil.
4. Install the new lter or the cleaned lter. Secure the Air Cleaner Cover before use. Gasket-style: Finger-
tighten until the gasket contacts the cylinder head, then about 1/2-2/3 turn more. Non-gasket-style: Finger-
tighten until the plug contacts the head, then about 1/16 turn more. 
5. Apply dielectric spark plug boot protector (not included) to the end of the spark plug and reattach the wire
securely.
