GENERAL SAFETY PRECAUTIONS

What to do if lubrication does not work:

Check that the oil channel in the bar is not obstructed. Clean if necessary.

Check that the oil channel in the gear housing is clean. Clean if necessary.

Check that the bar tip sprocket turns freely. If the chain lubrication system is still not working after carrying out the above checks you should contact your service workshop.

Checking wear on cutting equipment

Chain

Check the chain daily for:

Visible cracks in rivets and links.

Whether the chain is stiff.

Whether rivets and links are badly worn.

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.

Chain drive sprocket

Regularly check the degree of wear on the drive sprocket. Replace if wear is excessive.

Bar

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.

 

!

WARNING! A faulty cutting attachment

 

may increase the risk of accidents.
