SAFETY INSTRUCTIONS
Cutting equipment
Sharpening grass cutters and grass
blades
See the cutting attachment packaging for correct
sharpening instructions.
Sharpen blades and cutters using a single-cut flat file.
Sharpen all edges equally to maintain the balance of the
blade.
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.
General safety precautions
Starting
The complete clutch cover and shaft must be fitted before
the machine is started, otherwise the clutch can come
loose and cause personal injury.
IMPORTANT!
This section describes how to choose and maintain your
cutting equipment in order to:
Reduce the risk of kickback.
Obtain maximum cutting performance.
Extend the life of cutting equipment.
Only use cutting attachments with the guards we
recommend! See the chapter on Technical data.
Refer to the instructions for the cutting attachment to check
the correct way to load the cord and the correct cord
diameter.
Keep the teeth of the blade correctly sharpened! Follow our
recommendations. Also refer to the instructions on the
blade packaging.
!
WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened
blade increases the risk of kickback.
IMPORTANT! Always ensure the trimmer cord is wound
tightly and evenly around the drum, otherwise the machine
will generate harmful vibration.
!
WARNING! Always stop the engine before
doing any work on the cutting attachment.
This continues to rotate even after the
throttle has been released. Ensure that the
cutting attachment has stopped completely
and disconnect the HT lead from the spark
plug before you start to work on it.
IMPORTANT!
The machine is only designed for trimming grass, grass
clearing and/or forestry clearing.
The only accessories you can operate with this engine unit
are the cutting attachments we recommend in the chapter
on Technical data.
Never use the machine if you are tired, if you have drunk
alcohol, or if you are taking medication that could affect your

sure the spark plug cap and HT lead are not damaged.
Otherwise you could get an electric shock.
The machine operator must ensure that no people or
animals come closer than 15 metres while working. When
several operators are working in the same area the safety
