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.

•

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 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.

The position of the chain tensioning screw on our chain saws 
varies from model to model. See instructions under the 
heading What is what? to find out where it is on your model.

•

Release the knob by folding it out.

•

Turn the knob anti clockwise to loosen the bar cover.

•

Adjust the tension on the chain by turning the wheel down 
(+) for tighter tension and up (-) to loosen the tension.
