
NOTICE
The first 5 hours of run time are the break-in period for the
unit. During the break in period stay at or below 50% of the
running watt rating and vary the load occasionally to allow
stator windings to heat and cool. Adjusting the load will also
cause engine speed to vary slightly and help seat piston
rings. After the 5 hour break-in period, change the oil.

NOTICE
Synthetic oil may be used after the 5 hour initial break-in
period. Using synthetic oil does not increase the
recommended oil change interval. Full synthetic 5W-30
oil will aid in starting in cold ambient < 41º F (5º C)
temperatures.
Add Fuel
Use clean, fresh, regular unleaded gasoline with a minimum
octane rating of 87 and an ethanol content of 10% or less by
volume. ybc
DO NOT mix oil with gasoline.
1. Remove the gasoline cap.
2. Slowly add gasoline to the tank. Tank is full when gasoline
reaches the MAX fill line. DO NOT OVERFILL. Gasoline can
expand after filling. A minimum of ¼ in. (6.4 mm) of space
left in the tank is required for gasoline expansion, although
more than ¼ in. (6.4 mm) is recommended. Gasoline
can be forced out of the tank as a result of expansion if
overfilled, and can affect the stable running condition of
the generator.

NOTICE
If no Max fill line is present on your unit’s metal tank neck
as shown in picture, fill gasoline 1/2” (12.7mm) above white
tank filter.

DO NOT overfill the tank. Fill tank to approximately ¼ in.
(6.4 mm) below the top of the tank to allow for gasoline
expansion.
DO NOT pump gasoline directly into the generator at the
pump. Use an approved container to transfer the gasoline to
the generator.
DO NOT fill tank indoors.
DO NOT fill tank when the engine is running or hot.
