Is the feed belt still pushing the timber up against the bar as it’s cutting?

no, feed belt pushes timber to the length stop.  then belt stops.  bar is pulled down, chain starts, then cuts.  Belt does not start again untill I make it start.

Yes I know how it works used to have one . What I mean is once the timber has hit the stop is there tension in the feed belt so as you cut the timber is getting pushed forward ever so slightly from the tension in the belt . 

On the palax the stop retracts once the blade starts to come down meaning any tension in the belt disappears

Ahhh I get you, im not sure.  I am cutting longer & heavier lengths than I used to so its possible the extra weight is making the difference.  I'll check it out.  Thanks for the pointer

Just seen this thread. 

Sorry for the late comment but I have had the exact same issue with my Japa 300. 

It turns out that it is down to the prolite bar. Its just not made for the rigours of a processor. 

I switched to control cut (versa cut on the 370) and a massive improvement. 

Hope this helps

Thank you for your advise, I never got to the bottom of this.  Been using my spare processor as 370 did my head in.  So basically yours was cutting diagonal and wearing the bar out fast?  So the Oregon Control Cut bar & chain helped? or just the bar?  Any details greatly appreciated.
