What's on your bench today?

Had one of those Stihl HLA65s in recently, interesting that the size of the motor is tiny and no drive shafts but then that is pretty obvious when you think of it.

It kept flashing up three red lights and stopping. Looked it up and found I should be returning it to my Stihl Dealer........Mmmm, they obviously don't know of his reputation

After a bit of poking I found one of the crimp connectors going to the motor was fractured and sparking so crimped a new one on and bingo, one working trimmer....nice

Good to see your moving with the times.

Thought you would be looking to increase motor size, since they don't port.

Pretty common problem with those unfortunately.  Normally associated with a slightly bent motor shaft, which happens when the operator has had something jam up the blades.  Did you notice the motor wobbling at all when you turned it in situ?

Looked pretty good to me, no wobbling but a slight blue spark which I thought was typical brushed motor arcing but these look to be brushless motors and then found it

Any change of motor is likely to cock up a lot of other factors - these electric bits of kit are part of my exit strategy!

Reason  said it might be bent, is I've seen a few of these with broken terminals, all of them had a slight bend in the motor shaft, causing the motor to wobble slightly.  Trouble with this design, the output end of the shaft has a bearing either side of the gear which supports that bit nicely.  But the motor itself just sits in housing and it has one main lug on one side to stop it turning. When you have a major blade jam it tends to kick the motor over to one side.  It only has a really tiny shaft on the actual motor. It's a piss poor design IMO.

 

You will get the same battery error, with flashing lights if the blades get stuck, and the motor controller tells it to shut down instantly.   This brushless stuff is damn good, in a model car or plane though.

Question - can you get the bit of plastic that stops Stihl fuel and oil caps from falling off when you undo them? They are missing on my saw and it's a pain and I can't find them anywhere.

the stringy things?

The plastic bit that fastens onto the end of the string and wedges in the neck of the tank. I can't even find a picture of it. I will nip into the local Stihl shop next week and look on their parts list.

Is the MS170 tank neck same as the MS460 ? The ones I've seen have screw caps not flippy and the retainer on mine is different to the one in the picture. I called at the Stihl dealer and he will only do a complete cap so I have gone the DIY route, bent a bit of welding rod round the end of the string and pushed it into the neck and it does the job for now.
