The hourmeter said it was time to service the air filter. After the service has been preformed, does anything need to be done to the hourmeter?
The hourmeter will alert the owner continuously for one hour (of run time) before and until one hour after scheduled maintenance has been reached. This includes oil changes (at 100 hours) or air filter service (at 200 hours). As hours of operation continue to accumulate, the hourmeter will automatically reset itself until the next 100 or 200 hour service interval is reached. See the Hourmeter section of your owner's manual for additional information. The hourmeter on some generator models have a reset button that allows the operator to move between maintenance intervals and reset intervals by holding the reset button for nine seconds. NOTE: Not all generator models have a reset button.
How do I adjust the valve clearance?
Valve clearance adjustment is critical to proper engine operation and requires special tools and training. Instructions are covered in the Valve Clearance Adjustment section of your owner's manual. However, if you are uncomfortable preforming this service procedure, have your dealer maintain the generator's valve clearance at the intervals specified.
Can I operate my generator in the rain?
Portable generator should never be operated inside an enclosed space or contrary to any provision or warning contained in your Owner's Manual. However, portable generators are intended to be used during extreme weather and for the sensitive electronics on them, it is best if some sort of open covering can be used to protect it from direct rain or snow. Great options would be a car port or boat canopy with four open sides or a tarp hung from a tree. It is very important to provide adequate ventilation for the generator, so any sort of protection should be at least five feet from any side (including the top of the unit) while in use. Additionally, a portable generator should always be stored inside when not in use to prevent unnecessary wear and tear. BE ADVISED, the generator should NEVER be used in any enclosed space including, without limitation, a shed, home, garage, trailer, or vehicle, even if the doors are left open, as this can be a serious fire hazard and carbon monoxide risk.
How long can I operate the generator? Does it need a "break"?
Your generator can be operated continually. The highest priority is to maintain a proper oil level. Each time you add fuel, check the oil level as well. Add oil, if necessary, to keep the level at the upper mark on the dipstick. See the Checking Oil Level and Adding Fuel sections of your owner's manual for complete instructions on adding fuel and oil.
Is there anything special I need to do before I turn off my generator? Should I unplug my electrical devices?
Yes, remove all loads before turning the generator off. First, turn off all appliances, lights and items being powered by the generator. Then, unplug the items from the generator's receptacles and allow the generator to cool. Once you've done this, it is safe to turn the generator off. NEVER turn the generator off while loads are applied. Refer to the Generator Loads section of your owner's manual for complete instruction on adding and removing electrical devices.
How often should I start/operate my generator between outages?
Generac recommends starting a generator once a month and running the unit for about 30 minutes. Starting the unit monthly will help make sure that the generator is ready to turn on in the event of an outage.
