All Guardian home standby generators are fully automatic. When the power goes out, the unit comes on and powers the electrical loads. Once utility power is restored the generator switches the loads back to the utility lines and shuts itself off, waiting for the next power outage. There is no gasoline to store, and the unit works whether you are at home or away.

As with any modern machine, a certain amount of maintenance is required to ensure that your generator works when you need it to. A power outage is not the time to find out that your generator does not work. Routine maintenance by a qualified service technician can ensure that the generator will respond as intended.

There are four Maintenance Schedules for Guardian Standby Generators. Some tasks are recommended monthly, some semi-annually (6 months), some annually, and some bi-annually (24 months)

Basic Maintenance Tasks for these generators include:

• Check oil level. Add as necessary

• Check coolant level

• Check fuel gas delivery system for leaks and proper pressure

• Check and clean air inlets and outlets

• Check battery electrolyte level and specific gravity

• Check battery cables and posts. Clean as necessary

• Check unit for loose wiring connections. Correct as necessary
