Thank you for your question.
I can understand wanting to know where the oil drain plug in on the high wheel trimmer.
Like most lawn mowers today you change the oil by tipping the trimmer over on its side to drain the oil the same place that you fill the engine with oil.
On most of today's engines, with the application covering the drain plug they no longer reference this plug because it is not accessible.
I have given you a page from the owner's manual that has the instructions for this process.
Please reference these instructions below.
I hope this information will help answer your oil change question.
Thank you for using Manage My Life.
