C General advice on setting raker clearance

When you sharpen the cutting teeth you reduce the

RAKER CLEARANCE (cutting depth). To maintain cutting performance you must file back the raker teeth to the recommended height.

See the ”Technical data” section to find the raker clearance for your saw chain.

On a low-kickback cutting link the front edge of the raker lip is rounded. It is very important that you maintain this radius or bevel when you adjust the raker clearance.

We recommend the use of a

raker gauge to achieve the correct clearance and bevel on the raker lip.

!The risk of kickback is increased if the raker clearance is too large!

DSetting the raker clearance

Before setting the raker clearance the cutting teeth should be newly sharpened.

We recommend that you adjust the raker clearance every third time you sharpen the chain. NOTE! This recommendation assumes that the length of the cutting teeth is not reduced excessively.

• To adjust the raker clearance you will need a FLAT FILE and a RAKER GAUGE.

• Place the gauge over the raker lip.

Place the file over the part of the lip that protrudes through the gauge and file off the excess. The

clearance is correct when you no longer feel any resistance as you draw the file over the gauge.

3Tensioning the chain

!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 saw 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.
