teeth on one side of the bar first. Then turn the saw 
over and file the remaining teeth from the other side.

•

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.

•

When you sharpen the cutting teeth you reduce the 
raker clearance (=cutting depth). To maintain optimal 
cutting performance you must file back the raker lip to 
the recommended height.

•

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.

•

We recommend that you use our raker gauge to 
achieve the correct clearance and bevel on the raker 
lip.

•

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.

•

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.

•

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.
