Product Warranty Registration
Once your generator is installed you have two easy options to register your warranty.
(Recommended) Dealer Registration: The certified KOHLER dealer or installer that installed your generator can complete the post-installation registration form on your behalf.
Homeowner Registration: You can also register the unit yourself by filling out the warranty form and submitting your proof of purchase.
Your warranty coverage begins on the commissioning date if registered by your dealer, or defaults to the shipment date unless you provide proof of purchase during registration.

FAQs
Open the generator hood or access door and flip the circuit breaker to the “off” position (you’ll find the breaker near the digital controller). This shuts off power to the house (the load). lt’s a good idea to run the generator with no load for 2-5 minutes. Then press the “off” button on the controller.
Use the key that was included with the generator when it was sold. Turn the key 45 degrees to unlock. Lift the hood. If you can’t find the key, in many residential units, you may be able to use a flat head screwdriver.
Water and electricity are a very dangerous mix. If you can safely access it, power off the generator. (See FAQ: How do I manually power off the generator?) If it continues to run when submerged, internal damage to both engine and generator will be significant. If you can’t safely access the generator or the main line disconnect, do not make any attempt to turn it off.
We recommend checking the oil level after every 8-24 hours of operation, depending on the size and model of the generator. Oil change and filter change frequency and other routine maintenance varies per model, especially during periods of extended power outage. Check the operation manual included with your generator for a complete list of required maintenance procedures and schedules.
Open the hood of the generator.
Turn the circuit breaker OFF to disconnect power to the house. The breaker is either:
Near the controller on the right side, or
Above the control panel near the firewall behind the air filter.
Run the generator with no load for 2–5 minutes.
Press OFF on the controller to shut it down.
Wait 2 minutes for oil to settle.
Check the dipstick (yellow ring at the back of the engine):
Pull it out, wipe clean, reinsert, then pull out again.
Oil should be between the ‘F’ (full) and ‘L’ (low) marks.
If low, add oil (yellow cap or black stopper at the front of engine). Use 5W30 full synthetic unless conventional oil was previously used—do not mix types.
Add oil in small amounts, rechecking with dipstick. Do not overfill.
Press AUTO to restart the generator, then move the breaker to ON to restore power.
The dipstick has a bright yellow ring attached to the end. The location varies by generator, but it’s typically noticeable as soon as you open the access panel or hood.
Your generator ships with KOHLER Genuine Oil 5W-30 full-synthetic oil, which is the oil Kohler recommends. Although a synthetic blend may be used, our recommendation is full-synthetic oil. However, if you know that the oil has been changed out to conventional oil, then use only conventional oil from that point on. Do not mix synthetic oil with conventional oil.
The amount varies and depends on the engine model, length of time since the last oil change, amount of power the generator is producing and length of the power outage. Check the operation manual included with your generator for a complete list of required maintenance procedures and schedules.
