Does the an anvil on the 190 need changing /setting up? Our 190 is not chipping as it should. We've changed the hydrolic oil and put a new filter on but even with sharp blades the chip is stringy..

Hi Benedmonds

From what you describe tha anvil may require changing, the main thing to look for is the rounding off of the edge, if it has a radius on it of more than 3mm then it needs changing but it less than that you may be able to get away with tickling it up with a grinder to bring the edge back to square,
However please be very carefull as the anvil is hardened material and if you take too much off you will remove the hardness and render the anvil useless.

The optimum gap between the anvil edge and the blade is 2.5 to 3.00mm,
at this gap you will achieve the best results,
the larger the gap the less efficient the chipper becomes, which places extra load on the rotor bearings etc..

I would suggest that to bring you machine back up to its full potential you have the anvil changed.
