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 maintenance and use of a yard edger. One other area of concern or maintenance that you might want to be aware on your interchangeable yard tool machine, this particular one we can change the ends on it. We can go from a weed eater to an edger to a hedge trimmer and so on. There is a shaft that spins that goes through the , there is a shaft that goes through there, you want to lubricate it from time to time because well as also inside the other. Any lithium grease found at your local hardware store or supply store, lithium grease, a spray grease, simply spray it in the end and we will do the same for the other side. This will help make sure that there is plenty of lubrication in there to prevent wear and also provide more lasting full life.
