B   Rim sprocket (replaceable)

Regularly check the degree of wear on the drive sprocket. 
Replace if wear is excessive. Replace the drive sprocket 
whenever you replace the chain.

Both versions of sprockets have a needle bearing on the 
drive shaft, which has to be greased regularly (once a 
week). CAUTION! Use a high-quality bearing grease or 
engine oil.

See instructions under the heading Maintenance, Needle 
bearing lubrication.

Check the chain daily for:

•

Visible cracks in rivets and links.

•

Whether the chain is stiff.

•

Whether rivets and links are badly worn.

Replace the saw chain if it exhibits any of the points 
above.

We recommend you compare the existing chain with a 
new chain to decide how badly the existing chain is worn.

When the length of the cutting teeth has worn down to 
only 4 mm the chain must be replaced.

Check regularly:

•

Whether there are burrs on the edges of the bar. 
Remove these with a file if necessary.

•

Whether the groove in the bar has become badly 
worn. Replace the bar if necessary.

•

Whether the tip of the bar is uneven or badly worn. If 
a hollow forms on the underside of the bar tip this is 
due to running with a slack chain.

•

To prolong the life of the bar you should turn it over 
daily.
