New bar and old chains... they don't go together!

All that cack on saw is from blunt teeth ( an the wear pattern) chainsaws are nearly self cleaning with sharp teeth = no dust just shavings. K

My first ever boss in Dublin always believed and said that if the chain was razor sharp then you didn't need to clean the saw. 

 

He would even put a file over a new chain right out of the box which I never understood. 

 

The only cleaning that I ever did to a saw when I worked there was tipping petrol over the air filter every morning.

Saw one complete twat who could never sharpen a saw, take air cover off a Stihl 046, you could not EVEN see the air filter !  So caked in dust it was  ?  it is ALWAYS neglect that leads to failure.  K

Is that what happened Khriss ?  It helps to talk about it mate ...

Sanity has returned,  had a good socially distanced swim , a small glass of Merlot to rid the taste of chlorine, all is well ? K

Rob have you had customers calling in with similar failures on other brand bars you sell like gb cannon etc? Personally I like the sugi bars and haven't had an issue with them, but only runs 20" and a tiony sugi carving bar.

Had failures across the board on all brands of bars - pretty much proportionate to what we sell.. here's most recent one - sprocket nose failure - this may not have been anything to do with the drive rim [more likely over greased then run up too quickly] but rim had never been changed and even though hardly used the chain tie straps are already showing damage.

I'm curious about over greasing and running up too quickly. I guess it makes sense to gently spin the chain up after greasing so not to put too much stress on it, but how much is too much grease? I normally give it a pump, spin the sprocket half a turn or so and give it another pump to make sure fresh grease gets into all the rollers, then pull the chain around by hand a bit to just make 100% its all distributed well. I clean the grease hole out well beforehand too.

I stopped greasing sprocket noses years ago . I found that the grease picks up crud and grit ( in domestic situations , not so much in forestry ) and acts like a grinding paste and eventually the nose explodes  .

When you run the saw after greasing do so very very gently and allow any excess grease to get pushed out. I'm pretty sure [but by no means 100%] Stihl went to sealed nose bearings due to issues with people incorrectly greasing the nose.
