Chain constantly falls offI have an EGO trimmer with 2.5 amp battery, which I love. BUT...the EGO 5amp chain saw I purchased has given me nothing but trouble. The chain constantly falls off the bar, slowly loosening at first, then falling. This occurs despite constant tightening of the screw. This has happened with 2 EGO 16" chain saws...and lest you think I am a novice, I have had a 16" Craftsman for a dozen years, a Poulon chain saw, and numerous other power tools, which I have successfully used and personally serviced. With this same problem happening to two EGO chain saws back to back, I can only surmise it is a problem with manufacturing. Lastly, I am frankly surprised at all the great reviews of this chain saw...unless EGO deliberately eliminates bad reviews.

The issue with the chain falling off can be caused by the chain oil getting soaked into the thread on the slide cover knob.  

You can get some Dawn dishsoap and water and give the threads as well at the coven knob a good clean,  If that doesn't stop the knob from loosening when you are using the chainsaw, then you could put on a bit of Loctite 222 or 243 that will help thicken up and lock the knob better.  

Hope that helps you out.

make sure the large green knob that goes over the chain bar is sufficiently tight.  For all my complaints about the 14" CS, chains coming off is NOT one of them.  I've never had the chain come off even if for a few cuts, the chain was looser than specs.   I suspect there is something that you are doing that is contributing to your problem as I'm no expert and I've had zero issues with the chain coming off.

As far as a supposed "manufacturing problem", I'd bet a fair amount of money that is not the issue.   It's about adjustments and proper usage.

As to Daves point.  Are you checking the chain and bar before each use?  I know from experiance that there is a small amount of chain stretch when using the saw.  How often does the chain fall off?  is it multiple times in a single use, like chopping up a tree, or every so often like every 3rd of 4th time i use the chainsaw.  that might also give some more clues to what is going wrong for you.

I forgot all about what happened to my review!  I had a 5 star review for the 21" Mower that got rejected and Jennifer researched it for me.  It had to do with a link I had.  So it isn't just your review!
