Operation

2.8 BEFORE STARTING THE GENERATOR

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

2.8.1 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
Any attempt to crank or start the engine before it has

been properly serviced with the recommended oil may
result in an engine failure.

• Place generator on a level surface.
• Clean area around oil fill and remove dipstick.
• Slowly fill engine with oil through the oil fill opening until it
reaches the full mark on the dipstick. Stop filling occasionally
to check oil level.
• Install dipstick.
• Check engine oil level before starting each time thereafter.

2.8.2 ADDING GASOLINE


DO NOT light a cigarette or smoke when filling the fuel
tank.
Never fill fuel tank indoors. Never fill fuel tank when

engine is running or hot. Avoid spilling gasoline on a hot
engine. Allow engine to cool entirely before filling 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. Wipe
up any spilled fuel immediately.
10
• Use regular UNLEADED gasoline with the generator engine. Do
not mix oil with gasoline.
• Do not use gasoline with more than 10% alcohol such as E85
or Methanol.
• Clean area around fuel fill cap, remove cap.
• Slowly add unleaded regular gasoline to fuel tank. Fill to bottom
of screen filter. Be careful not to overfill (Figure 10).
• Install fuel cap and wipe up any spilled gasoline.
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.

2.9 COLD WEATHER OPERATION/DE-ICER

Under certain weather conditions (temperatures below 40° F (4°
C) and a high dew point), the engine may experience icing of the
carburetor and/or the crankcase breather system. To eliminate
this problem, this generator engine is fitted with a winter/summer
valve. This directs hot air into the carburetor during cold weather
operation. Always make sure the winter/summer valve is in the
correct location relative to the weather conditions.
