After finishing work N Disconnect the plug from the wall outlet. N Slacken off the chain if you have retensioned it at operating temperature during cutting work.

The drive link tangs will otherwise scrape along the bottom of the groove - the cutters and tie straps will not ride on the bar rails. 1 3 143BA026 KN N Turn 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. N Regularly clean the oil inlet hole (1), the oilway (2) and the bar groove (3). N Measure the groove depth - with the scale on the filing gauge (special accessory) - in the area used most for cutting. MSE 170 C, MSE 210 C 35
