Insufficient oil, or a burned up roller tip.  Check the pump output without the bar and make sure the oil holes in the bar is not plugged

I did some searches on roller tips being burnt and came across what seems to be a controversial subject.  Should you grease the oiler tip or not.  One camp says definately not because grease attracts dirt and abrasives which will destroy the tip.  They say the oil from the oiler should lubricate the roller well, and to grease would be a cardinal sin. There is apparently a special lil grease gun for that very purpose.

---UPDATE---
Well I just chatted with Echo and they said the oiler does it, no need for grease.
