GENERAL SAFETY PRECAUTIONS
Sharpening cutting teeth
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 0.16 inch (4 mm) the chain is worn out and should be replaced.
General advice on adjusting depth gauge setting
•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.

Adjustment of depth gauge setting
•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.
Tensioning the chain
WARNING! A slack chain may jump off
! the bar 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
Tension the chain as tightly as possible, but not so tight that you cannot pull it round freely by hand.
