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 y
ou 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
inf
ormation 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
ne
w 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 y
ou cannot pull it round freely by hand.

• Loosen 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 scre
w 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.
The position of the chain tensioning screw on our chain
sa
ws varies from model to model. See instructions under
the heading What is what? to find out where it is on your
model.

WARNING! A slack chain may jump off
the bar and cause serious or even fatal
injury.
