Step 1: Turn off Your Weed Eater

If you’re looking to change the refill on your Stihl weed eater, the first thing you need to do is turn it off. Safety should always be your number one priority when working with power tools, so make sure the engine is completely off and the spark plug is disconnected. Once you’ve done that, you can begin loosening the head that holds the spool in place.

Depending on your model, this may involve pressing tabs or removing screws. Once the head is off, carefully extract the old spool and replace it with a new one. Make sure to wind the line tightly and evenly, following the manufacturer’s instructions.

Regardless, take your time and double-check that everything is in place before reattaching the head and starting up your weed eater again.

If you’re not sure where the spool cover is located, consult your user manual or do a quick search online for your specific Stihl model. Once you’ve found the spool cover, you’re one step closer to replacing the trimmer line and getting back to your lawn care tasks.
