What is the difference between a transfer switch that is rated for a service entrance and one that’s rate for a non-service entrance? Expand

A service-entry-rated switch comes equipped with a main-line disconnect breaker built into the transfer switch.  This is a nationwide code requirement when the transfer switch is wired directly into the incoming main power line for whole-house power.  A non-service-entry-rated-switch requires the addition of a disconnect breaker at the jobsite.  The service-entry-rated switch saves you time and money during the installation process.

How long can I let my generator run before I check my oil? Expand

KOHLER recommends that you check your oil every 8 hours of operation, depending on the size and model of the generator.  Check your operation manual included with your generator for a complete list of required maintenance procedures and schedules.

When is the best time to check my oil? Expand

Check your oil level, prior to a storm.  If the unit has been running for 8 hours or more, shut the unit down and let it sit for 2-3 minutes, check and add oil as needed.

A large metal key is included in your owner’s packet.  Insert the key and turn it 45 degrees to open the top of the hood or side-access door of the generator.

How do I manually power “off” my generator? Expand

Open the generator hood or flip the circuit breaker to the “off” position (near the digital controller)  This shuts off the power to the house (the load).  It’s a good idea to run the generator with no load for 2-5 minutes.  Then press the “off” button on the controller.

Which oil should I use? Expand

Your generator comes with the Kohler Genuine oil 5W-20 full-synthetic, which is the oil Kohler recommends.  Although a synthetic blend may be used, our recommendation is to use full synthetic oil however, if you know that the oil has been changed out to conventional oil, then use only conventional from that point on.  Do not mix synthetic oil with conventional oil.
