GENERAL SAFETY PRECAUTIONS

Sharpening the saw blade

• See the cutting attachment packaging for correct
sharpening instructions.
A correctly sharpened blade is essential for working
efficiently and to avoid unnecessary wear to the blade and
brush cutter.
• Make sure that the blade is well supported when you
file it. Use a 5.5 mm round file with a file holder.
• The filing angle is 15°. File alternate teeth to the right
and those in between to the left. If the blade has been
heavily pitted by stones it may be necessary to dress
the top edges of the teeth with a flat file, in exceptional
cases. If so, this should be done before filing with a
round file. The top edges must be filed down by the
same amount for all the teeth.
Adjust the blade setting. This should be 1 mm.
