2.6 BEFORE STARTING THE GENERATOR

Prior to operating the generator, engine oil and gasoline will need to
be added, as follows:

2.6.1 ADDING ENGINE OIL

All oil should meet minimum American Petroleum Institute (API)
Service Class SJ, SL or better. Use no special additives. Select the
oil's viscosity grade according to the expected operating temperature
(also see chart).
• Above 32 °F (0 °C), use SAE 30
• Between 40 °F and -10 °F (4 and -32 °C), use 10W-30
• Synthetic 5W-30 for all temperature ranges

Any attempt to crank or start the engine
before it has been properly serviced with the
recommended oil may result in an engine
failure.
1. Place generator on a level surface (not to exceed 15° in any
direction).
2. Clean area around oil fill and remove oil fill cap and dipstick.
3. Wipe dipstick clean.
4. Slowly fill engine with oil through the oil fill opening until it
reaches the high mark on the dipstick (Figure 9). Stop filling
occasionally to check oil level. Be careful not to over fill.
5. Install oil fill cap and finger tighten securely.
6. Check engine oil level before starting each time thereafter.

2.6.2 ADDING GASOLINE



Gasoline is highly FLAMMABLE and its vapors
are EXPLOSIVE. Never fill fuel tank indoors.
Never fill fuel tank when engine is running
or hot. Allow engine to cool entirely before
filling fuel tank. Avoid spilling gasoline on HOT
engine. DO NOT light a cigarette or smoke
when filling the fuel tank.

Do not overfill the fuel tank. Always leave room
for fuel expansion. If the fuel tank is overfilled,
fuel can overflow onto a HOT engine and cause
FIRE or EXPLOSION.
1. Use regular UNLEADED gasoline with the generator engine. Do
not use any gasoline with more than 10% added Ethanol, and
never use E85 gasoline. Do not mix oil with gasoline.
2. Clean area around fuel fill cap, remove cap.
3. Slowly add unleaded regular gasoline to fuel tank. Be careful
not to overfill (Figure 7).
4. Install fuel cap and wipe up any spilled gasoline.

Fuel
IMPORTANT: It is important to prevent gum deposits from forming
in fuel system parts such as the carburetor, fuel hose or tank during
storage. Alcohol-blended fuels (called gasohol, ethanol or methanol)
can attract moisture, which leads to separation and formation of acids
during storage. Acidic gas can damage the fuel system of an engine
while in storage. To avoid engine problems, the fuel system should
be emptied before storage of 30 days or longer. See the "Storage"
section. Never use engine or carburetor cleaner products in the fuel
tank as permanent damage may occur.
