STOPPING YOUR GENERATOR
CAUTION!
Unplugging running devices can cause damage to the generator. Never stop the engine with elec-
trical devices connected and running.
OPTION 1: AUTOMATIC FUEL SHUTOFF (RECOMMENDED)
The WEN 4500W Inverter Generator is equipped with automatic fuel shutoff. This feature turns off the flow of fuel,
allowing for the generator to use up the remaining fuel from the carburetor before turning off. This prolongs the
lifespan of the generator by preventing build-up and blockages caused by stagnant fuel inside of a carburetor.
1. Turn off all electrical devices prior to unplugging them from
the generator. Unplugging running devices can cause damage to
the generator.
2. Allow generator to run at no load for a few minutes to stabilize
internal temperatures.
3. Turn the engine switch to the “OFF” position (Fig. 15).
4. The engine will continue to run until the majority of the fuel in
the carburetor is consumed. It will then shut off automatically.
This feature helps to prevent the carburetor from being clogged
by stale fuel, extending your generator’s lifespan.
OPTION 2: MANUAL SHUTOFF
In case you are in a hurry and do not want to wait for the generator to automatically shut down, the manual shutoff
feature is available. However, this method will leave stagnant fuel in the carburetor, possibly causing blockages,
a shortened lifespan, and other maintenance issues. If this approach is frequently taken, make sure to drain your
carburetor before any long storage periods.
1. Turn off all electrical devices prior to unplugging them from the generator. Unplugging running devices can cause
damage to the generator.
2. Press the “MANUAL SHUTOFF” switch and hold it down in the “OFF” position for about 6 seconds until the engine
shuts off.
WARNING!
Allow the generator to cool down before touching areas that become hot during use.
CAUTION:
Allowing gasoline to sit in the fuel tank for long periods of time can make it difficult to start the gen-
erator in the future. Never store the generator for extended periods of time (over 2 months) with fuel in the fuel
tank. Refer to “Storing the Generator.”
