NTurn the guide bar over – every time you sharpen the chain and every time you replace the chain – this helps avoid one-sided wear, especially at the nose and underside of the bar.

(3).

NMeasure the groove depth – with the scale on the filing gauge (special accessory) – in the area used most for cutting.
