I have one of those LIDL chain sharpeners and a LIDL chainsaw, I ran the saw without any oil which blunt it very quickly.
After watching some videos of how to use the sharpener I made an attempt to sharpen it, which went OK however it was hard to sharpen each tooth the same amount and doesn’t do the rakers.
I went to reassemble and the chain tensioner broke, so can’t comment if it worked.
I think I will get a proper file fir my next saw.
