To sharpen cutting teeth you will need a round file and a file 
gauge. See instructions under the heading Technical data for 
information on the size of file and gauge that are 
recommended for the chain fitted to your chain saw.

•

Check that the chain is correctly tensioned. A slack chain 
will move sideways, making it more difficult to sharpen 
correctly.

•

Always file cutting teeth from the inside face. Reduce the 
pressure on the return stroke. File all the teeth on one side 
first, then turn the chain saw and file the teeth on 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 tooth (A) the depth gauge 
setting (C) will decrease. To maintain optimal cutting 
performance the depth gauge (B) has to be filed down to 
achieve the recommended depth gauge setting. 

See instructions under the heading Technical data to find 
the correct depth gauge setting for your particular chain.

•

The cutting teeth should be newly sharpened before 
adjusting the depth gauge setting. We recommend that 
you adjust the depth gauge setting every third time you 
sharpen the cutting teeth. NOTE! This recommendation 
assumes that the length of the cutting teeth is not reduced 
excessively.

•

You will need a flat file and a depth gauge tool. We 
recommend that you use our depth gauge tool to acheive 
the correct depth gauge setting and bevel for the depth 
gauge.

•

Place the depth gauge tool over the chain. Detailed 
information regarding the use of the depth gauge tool, will 
be found on the package for the depth gauge tool. Use the 
flat file to file off the tip of the depth gauge that protrudes 
through the depth gauge tool. The depth gauge setting is 
correct when you no longer feel resistance as you draw 
the file along the depth gauge tool.

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.
