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 4 mm (0.16") 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
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!
!
WARNING! A slack chain may jump off the
bar and cause serious or even fatal injury.
