MAINTENANCE
Filing the saw blade
• See the cutting attachment packaging for correct
sharpening instructions.
• A correctly filed blade is essential for working efficiently
and to avoid unnecessary wear to the blade and clearing
saw.
• 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.
Maintenance schedule
Below you will find some general maintenance instructions.
Daily maintenance

• Check that the stop switch works correctly.
• Check that the cutter does not rotate when the engine is
idling.

guard if damaged.
• Check that the trimmer is properly centered, sharp, and
without cracks.
• Check that the trimmer head is undamaged and not
cracked. Replace the trimmer head if necessary.
• A non-balanced blade/trimmer head induces heavy
vibrations that may damage the machine.

air intake near the starter is not blocked.

Use special grease.
