GENERAL SAFETY PRECAUTIONS
Sharpening the saw blade
Trimmer head
IMPORTANT!
Always ensure the trimmer cord is wound tightly and evenly
around the drum, otherwise the machine will generate
harmful vibration.
•
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 clearing saw.
•
Only use the recommended trimmer heads and trimmer
cords.These have been tested by the manufacturer to suit
a particular engine size.This is especially important when
a fully automatic trimmer head is used. Only use the
recommended cutting attachment. See the chapter on
Technical data.
•
•
Smaller machines generally require small trimmer heads
and vice versa. This is because when clearing using a
cord the engine must throw out the cord radially from the
trimmer head and overcome the resistance of the grass
being cleared.
•
•
Make sure that the blade is well supported when you file
it. Use a 5.5 mm round file with a file holder.
The length of the cord is also important. A longer cord
requires greater engine power than a shorter cord of the
same diameter.
•
•
Make sure that the cutter on the trimmer guard is intact.
This is used to cut the cord to the correct length.
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.
To increase the life of the cord it can be soaked in water
for a couple of days.This will make the line tougher so that
it lasts longer.
Adjust the blade setting. This should be 1 mm.
