100302 - 4000W DIGITAL HYBRID PORTABLE GENERATOR
ASSEMBLY

 CAUTION
This engine is equipped with a low oil shut-off and will stop
when the oil level in the crankcase falls below the threshold
level.

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 85 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 red circle on screen. 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.
3. Screw on the gasoline cap and wipe away any spilled fuel.
 CAUTION
Use unleaded gasoline with a minimum octane rating of 85
and an ethanol content of 10% or less by volume.
DO NOT light cigarettes or smoke when filling the tank.
DO NOT mix oil and gasoline.
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 fuel container to transfer the gasoline to the
generator.
DO NOT fill tank indoors.
DO NOT fill tank when the engine is running or hot.
 WARNING
Pouring gasoline too fast through the fuel screen may result
in gasoline splashing over the generator and operator while
filling.

NOTICE
The generator engine works well with 10% or less ethanol
blend gasoline. When using ethanol-gasoline blends there are
some issues worth noting:
– Ethanol-gasoline blends can absorb more water than
gasoline alone.
– These blends can eventually separate, leaving water or
a watery goo in the tank, fuel valve and carburetor. The
compromised gasoline can be drawn into the carburetor
and cause damage to the engine and/or potential hazards.
– If a fuel stabilizer is used, confirm that it is formulated to
work with ethanol-gasoline blends.
– Any damages or hazards caused by using improper
gasoline, improperly stored gasoline, and/or improperly
formulated stabilizers, are not covered by manufacturer’s
warranty.
It is advisable to always shut off the gasoline supply and
run the engine to starvation after each use. See Storage
instructions for extended non-use.
