91VXL v PMM3

[openspaceman]

I got given a barely used einhell 40cc saw to repair last week, couldn't find fault other than a slightly bent tensioning screw and chain was missing.

 

I ringed up 2 canter loads of 18" pine yesterday and it seemed ok but the new VXL chain I bought seemed to snag quite easily. I was wondering if the low profile Stihl PMM3 used on the pole saws would be worth trying for its low snatch and narrow kerf, any thoughts?

Both chains are low profile, but the PMM also is narrow kerf (.043 gauge vs. .050 - meaning you will need a new bar).

 

Issues with the VXL are well known from other saws as well, and the cause said to be the very long cutters. It has Carlton cutters, so avoid Carlton as well.

Other .050 lo-pro chains may work on your saw, like 63PM, 63PS or 91PX (VX as well, if you still can find it).

Thanks for that, I had seen it suggested to grind the backs off the cutters. If I ever wear the bar out I will try the narrower one, what are the drawbacks e.g is the chain easier to snap?

VXL tends to chatter a lot. Presumably, the XL means xtra long(cutters). The shorter a cutter top plate is, the smoother the cut, and the faster the cut. The only advantage to a longer top plate is life span of the cutter, but it puts the life where you can't really use it well - towards the back of the cutter. A terrible, terrible design.
