How To Change the Air Filter on the FLEX Power Base

This state-of-the-art power base is a 208cc OHV, all-season 4-cycle engine. The rugged Latch 'n Lock' system has endured the Troy-Bilt® test of quality, with hundreds of hours of accelerated use - and is fully integrated with a self-propelled transmission for easy operation.

It is recommended to always inspect the air filter before each use and every 5 hours of operation. When the air filter is ready to be changed, make sure that the engine is upright and level. It is best to change the air filter after every 100 hours of use or every season.
