SAFETY INSTRUCTIONS
� File all the teeth to the same length. When the length of the cutting teeth is reduced to 4 mm (0.16") the chain is worn out and should be replaced. � Place the �le over the part of the lip that protrudes through the gauge and �le off the excess. The clearance is correct when you no longer feel any resistance as you draw the �le over the gauge.

General advice on setting raker clearance
� When you sharpen the cutting teeth you reduce the raker clearance (=cutting depth). To maintain optimal cutting performance you must �le back the raker lip to the recommended height. See the Technical data section to �nd the raker clearance for your particular chain.

Tensioning the chain

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. The position of the chain tensioning screw on our chain saws varies from model to model. See the What is what? section to �nd out where it is on your model. Tension the chain as tightly as possible, but not so tight that you cannot pull it round freely by hand.

�

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! � Undo the bar nuts that hold the clutch cover/chain brake. Use the combination spanner. Then tighten the bar nuts by hand as tight as you can.

Setting the raker clearance

�

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 �at �le and a raker gauge.

�

�

Raise the tip of the bar and stretch the chain by tightening the chain tensioning screw using the combination spanner. Tighten the chain until it does not sag from the underside of the bar.

�

Place the gauge over the raker lip.
