The Bar adjustment is normally a nut that screws onto a fixed threaded bolt. My advice would be to replace the nuts with Nyloc nuts and grip washers or use Loctite Red on what you have.

I can zoom in on this image, but the resolution isn't good enough to see the bar fixing clearly.

We added an O-ring to the gas cap, used a Goof-Off cap to replace the bar oil cap, added a flat-washer to hold the plastic saw cover. Since the pole joints slip out of place, he used very short self-tapping screws (made for steel studs) to fasten more permanently. He started the holes with the screws, but then backed them out and shortened them by grinding off 3 threads. Then he tightened them.

Mainly, we just found the problem that solves the start / fuel issues many have had on the Maxtra Pole Saw!!!!!!!! My husband noticed the carburetor seemed giggly. He had removed the air cover and been starting it by pouring a little mixed fuel directly into it, It would run a little bit, then die. I watched the fuel line, and even after pumping it up, it would get air bubbles in the line while it ran, and then drain completely. The fuel line is really short so we both thought it just might not be far enough into the fuel -- but that was not it. He saw the two nuts inside the breather and decided to remove those and the carburetor. A little tricky if you have NO mechanical skill at all, but really pretty easy, take photos if you need to remember how it goes. He found that the manifold piece behind that had 2 bolts holding it and they were VERY loose. This created a horrible air gap. He gently tightened those bolts with a hex bit keeping in mind he did not want to strip them. (Now we wish we had used Lock-Tite). We put it back together, pumped the primer AND IT STARTED ON THE FIRST PULL!!!! First pull, ran continuously, and even idled!!!! We are going to replace the fuel line with a little longer tube tomorrow. This baby will hum now!

Check you fuel line for cracks.

I have seen this issue before, having trouble remembering the fix though. Is there any more info you can give me about the problem?

Had the same problem with my Stihk hs 81 R hedge trimmers. Ive stripped it down and found that the clutch drum had sheared. Hope this helps.

It is likely that the drive pin on the gear has sheared. You will need to replace it.

Un less your trimmer is a split sharft model ie you can take of the blade by undoing a handle then the answer is no you will have to buy a diff trimmer

some have a small bolt behind it, or your threads are strip
