GENERAL SAFETY PRECAUTIONS
Sharpening cutting teeth Adjustment of depth gauge setting

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

�

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 �at �le 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.

�

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

� � 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.

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 �at �le to �le 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 �le along the depth gauge tool.

�

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.

Tensioning the chain

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 �led down to achieve the recommended depth gauge setting. See instructions under the heading Technical data to �nd the correct depth gauge setting for your particular chain.

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. Tension the chain as tightly as possible, but not so tight that you cannot pull it round freely by hand.

!

WARNING! The risk of kickback is increased if the depth gauge setting 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.
