SAFETY INSTRUCTIONS
Sharpening cutting teeth
� We recommend that you use our raker gauge to achieve the correct clearance and bevel on the raker lip.
To sharpen cutting teeth you will need a round �le and a �le gauge. See the Technical data section for information on the size of �le and gauge that are recommended for the chain �tted to your chain saw.
!
� Check that the chain is correctly tensioned. A slack chain will move sideways, making it more dif�cult to sharpen correctly.
WARNING! The risk of kickback is increased if the raker clearance is too large!
Setting the raker clearance
�
�
Always �le cutting teeth from the inside face. Reduce the pressure on the return stroke. File all the teeth on one side �rst, then turn the chain saw over and �le the teeth on the other side.
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.
�
�
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 gauge over the raker lip.
�
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.
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.
Tensioning the chain
�
On a low-kickback cutting link the front edge of the raker lip is rounded. It is very important that you maintain this radius or bevel when you adjust 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. 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.
