Yes. When plugging directly into the generator, we recommend that you turn your devices, tools and appliances to the "off" position before connecting to the generator. If you are connecting through a manual transfer switch, we recommend that you turn all breakers connected to the manual transfer switch to the off position before transferring power.  Further, you should turn off and unplug any devices from the generator before shutting the generator down.  Please refer to the Owner's Manual for additional instructions and safety precautions.
