GENERAL SAFETY PRECAUTIONS maintain this radius or bevel when you adjust the raker clearance. Tensioning the chain • We recommend that you use our raker gauge to achieve the correct clearance and bevel on the raker lip. WARNING! The risk of kickback is ! increased if the raker clearance is too large! Setting the raker clearance WARNING! A slack chain may jump off ! and cause serious or even fatal injury. • The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack. • Check the chain tension every time you refuel. NOTE! A new chain has a running-in period during which you should check the tension more frequently. • Tension the chain as tightly as possible, but not so tight that you cannot pull it round freely by hand. • Before setting the raker clearance the cutting teeth should be newly sharpened. We recommend that you adjust the raker clearance every third time you sharpen the chain. NOTE! This recommendation assumes that the length of the cutting teeth is not reduced excessively. • To adjust the raker clearance you will need a flat file and a raker gauge. - Undo the bar nut. • Place the gauge over the raker lip. • Place the file over the part of the lip that protrudes through the gauge and file off the excess. The clearance is correct when you no longer feel any resistance as you draw the file over the gauge. - Tension the chain by turning the chain tensioning screw clockwise using the combination spanner. The chain should be tensioned until it does not sag from the underside of the bar. - Tighten the bar nut using the combination spanner. Check that the chain can be pulled round easily by hand. 12 - English
