new bar and chain smoking

[symamania]

Gday guys quick question I got a new 36 " bar for my stihl 076 I put it all together and went to run it and it started to smoke, its getting oil the chains not to tight it spins over by hand. Has any one else experienced this maybe its my bar oil?

Just seems strange for a new bar and chain to have white smoke coming out of it.

cheers

It is likely paint or a corrosion inhibitor burning off the rails.

[clww]

I'm with sawguy, too. How much is it smoking? Faintly or can't-see-the-tree smokin?

How's it cutting by the way?  Is it cutting straight through, just smoking?

[symamania]

I can see through the smoke, haven't tried cutting with it  yet because wasnt sure if it was ok to do so with the smoke. just never had a new bar and chain do this before but this is my first big bar and chain

  Is it the right bar and chain for you saw, check to make sure the chain is in the drive sprocket..  Chain brake off and not hung up.  Did you match up the chain gauge to the bar.   Steve

yeah pretty sure its right just went down to the stihl dealer and this is what they gave me so assuming its all good

[beenthere]

Wouldn't "assume" it is right, as even Stihl dealers have hired employees who don't have a clue.

Shouldn't be any smoke... so I'd "assume" that it isn't "all good". Best a trip back to the Stihl dealer, IMO.

I looked at this thread cause the title made me think some one was reminiscing about the seventies and I find it is only about chainsaws
gww

[symamania]

hahahahah yeah I see what you mean

[joe_indi]

Have you checked whether the bar is smoking from getting heated or is it smoking from the exhaust gases hitting it?
This is because you said 'white smoke'

Is it a Stihl chain ? It sure sounds like you might have an .058" chain in a .050" bar. Look on the side of the bar it might have the gauge stamped there. Should be .050 or .058 maybe 50 or 58. If your chain has 72 stamped on the drive part of the link (at least for oregon chains) then you need an .050 bar. If it has 73 stamped on the chain then you need a .058 bar.
If it is a Stihl chain it should have a 1, 3, 5, 6, or 0, stamped on the chain they equal:
1=.043
3=.050
5= .058
6=.063
0= .080

The point is that the thickness of the chain needs to be the same as the width of the grove in the bar. This is gauge and if the chain is a bit too thick it will cause friction because there will not be room for oil film in between the bar and chain
