Secondary oiler kit that allows you to introduce oil onto the end of the bar direct to the cutting face. This can help keep the chain better lubricated at the expense of more weight. Depending on the oil used in the tank you may have to drill out the oiler bolt a little wider. Watch our videos on drilling the bar. The oiler kit is not essential – but it does help for smoother milling.
