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 40° F, use SAE 30
• Below 40° F and down to 10° F, use 10W-30
• Below 10° F, use synthetic 5W-30
1 0 W -3 0 1 0 W - 30
Sy nth eti c 5W -3 0 Synthetic 5W-30
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. Fill to
bottom of screen filter. Be careful not to overfill (Figure 10).
4. Install fuel cap and wipe up any spilled gasoline.
