•

File all the teeth to the same length. When the length 
of the cutting teeth is reduced to 4 mm (5/32") 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.

•

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.

•

Raise the tip of the bar and stretch the chain by 
tightening the chain tensioning screw using the 
combination spanner. Tighten the chain until it does 
not sag from the underside of the bar.

•

Use the combination spanner to tighten the bar nuts 
while lifting the tip of the bar at the same time. Check 
that you can pull the chain round freely by hand and 
that it does not sag from the underside of the bar.
