GENERAL SAFETY PRECAUTIONS
12 – English
• 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.
Trimmer head
• 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.
• 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.
• 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.
IMPORTANT!
Always ensure the trimmer cord is wound tightly and evenly
around the drum, otherwise the machine will generate
harmful vibration.
