How long it lasts
Replace it when engine power drops noticeably and the filter is dirty or damaged, STIHL says (its paper filters last more than a year on average); fit the new spark plug after about 100 hours of use.
After replacing: No reset needed.
How to change the 4180 007 4103 service kit
Watch the guide or follow the steps.
- 1Stop the engine and let it cool. Turn the choke knob to the closed position so no dirt gets into the intake.

- 3Take out the paper air filter and fit the new one from the kit, then refit the cover.
- 4Take off the spark plug cover, pull off the boot, unscrew the plug and screw in the new one (gap 0.5 mm, STIHL says). Press the boot firmly home.
