How to replace trim head on echo SRM-225
Lynnola
asked on 2023-03-10
Hello Lynnola, thank you for your question. The Head you have chosen is for a SRM-226T, not a SRM 225. For the SRM-225 the Head is 99944200907B. Take a fat-head screwdriver see as you rotate the weed whacker head there's an opening and the hole is lined up. You put it in and then the
most important feature about replacing your weed whacker head is that it's reverse threaded. This means turn left to tighten and turn right to loosen. o now what you want to do is pull it down to the right and it pops right off and as you can see the whole head is spinning so unwind this off o now what you want to do is pull it down to the right and it pops right off. We hope this helps.

for model number Echo 230S
asked on 2022-03-12
Hi Gomez,
Thank you for your question. Before we can provide you with information on the head for your trimmer, we will also need the serial number from it. It will be found on the same label as the model number. The label will sometimes be found next to the air filter cover or above the fuel tank. If you could resubmit your question with this information, we would be happy to help you. We are open 7 days a week. We look forward to hearing from you!
