Hi! My name is Matthew Christian from Tampa, Florida and on behalf of Expert Village, today I would like to talk to you about the proper use and maintenance of a leaf blower. Now this particular leaf blower is a backpack model meaning that you strap it to your back. It makes it easier to hold. Instead of having to carry it by hand, you can put it on your back just like a backpack when you were a kid and went to school. Everyone's body is different; we are all built differently. So the straps may need to be adjusted. It is relatively simple to adjust the straps, to tighten the straps to make the straps smaller. So you feed a little bit of the strap through the loop and then pull it down and we will pull the excess back through here. Hence we've effectively shortened the strap. Conversely if you need to lengthen it, actually these are extended as far as they will possibly go. There is not much more slack that we could use. But it is relatively simple. That is to make the strap smaller and to make the strap larger, we will just feed it back through again and there you go.
