Problem

[Oregon Engineer]

Yeah, I hate the stupid chain tensioner built into the bar. And I have noticed even after tightening the chain it will come loose and fly off....

Are you mainly felling and bucking trees for firewood or cutting brush?

When do you experience the chain throw?
cutting small limbs
bucking logs
cutting with the tip


Which of the cutting techniques are you using?
felling cuts
nose boring
down bucking
up bucking
top rail delimbing (sometimes called knot bumping)
etc.

I'm interested in understanding the conditions under which you are experiencing the problems.

A worn sprocket will exacerbate the problem for sure, and the chain is
likely damaged as a result. So both will likely need replaced.
As far as the Intenz bar is concerned, I did not really bring it in the mix,
but I did, in reality, as I knew down deep what bar it had,
and I fully respect Oregon for actually monitoring this site, and have the balls to post here, as most of the industry engineers are gutless and have no regard for any input from techs or users.
In fairness to the intenz system, his sprocket and chain are likely worn out,
but some pics would help.

whats wrong ?

i had a customer bring me one (very low hr saw) that had a severly worn out pilot bearing within a slightly moderately worn spur style drum. causing the symptoms you have described, to much torsional twisting , combined with the intenze style adjustment within bar backing up from poor quality construction. the two combinations cause constant derailment. also pay close attention to your bar. as all othors have mentioned, for guide rail inconsistencys. ect. good luck

But because I am an ahole, I am not going to let this thread "fade" away...

i converted my customers saw using oregons conventional. .325 pitch style conventional bar, as well as adding conventional hardware adjuster ect. to the poulans chain brake cover, allowing him to make conventional style adjustments, replaced pilot bearing,spur drum assembly, in his particular case he ( i feel ) was running his chain origionally much to tight, causing premature wear on the adjustment mechanism within his bar.also the pilot bearing and spur drum assembly, in his particular case he ended up very satisfied!!! with conventional oregon 14 inch roller nose hardware, and it is holding up very well to the heavy cutting he is subjecting his saw to. as this may ? be a solution to your problem as well

ive just looked into my previous repair records for poulan and found that his saw was a 2003 model year 295 pro , model. oregons web site can help with any part ##s if you dont have a retailer in your close proximity. for bar/chain combo. ect. i hope this helps.

I usually just add the conventional screw adjuster, and they can use the
Intenz bar and original chain.

Fish , the PP4218 , PP4218 Type1 , and PP4218 Type 2 don't have the clutch cover with the hole to accept a bar adjust kit . The PP4218AVHD does have a hole in the clutch cover for the bar adjust kit .

Sometimes there is a slot in the sprocket cover, or in the saw,, sometimes
I have to improvise a little. The newer saws, maybe not, since I work where I
work now, I do not ever see any Poulans, but my main point was, you can still use the intenz bar, with the conventional screw tensioner.
