Normal maintenance
Trimmer would not run. 15 minutes later, after replacing a few parts. Up and running again, like new.Easy as turning a nut driver.

Works Well; No Instructions
Put the new spark plug, primer bulb, and air filter in my Stihl F45 string trimmer, and now it runs much better. Note that there are no instructions, so I haven’t tried to install the new fuel filter and fuel line.
