damaged. In case of doubt, have the
machine checked by your servicing
dealer.
Do not operate your power tool with the
starting throttle lock engaged – engine
speed cannot be controlled in this
position.
Special care must be taken when
working in difficult, over-grown terrain.
When cutting high scrub, under bushes
and hedges: Keep cutting tool at
minimum height of 15 cm to avoid
harming small animals.
Before leaving the power tool
unattended: Shut off the engine.
Check the cutting attachment at regular
short intervals during operation or
immediately if there is a noticeable
change in cutting behavior:
– Turn off the engine. Hold
brushcutter firmly and wait for the
cutting attachment to come to a
standstill.
– Check condition and tightness, look
for cracks.
– Check sharpness.
– Replace damaged or dull cutting
attachments immediately.
Clean grass and plant residue off the
cutting attachment mounting at regular
intervals – remove any build up of
material from the cutting attachment and
deflector.
To reduce the risk of injury, shut off
the engine before replacing the cutting
attachment.
Do not continue using or attempt to
repair damaged or cracked cutting
attachments by welding, straightening or
modifying the shape (out of balance).
This may cause parts of the cutting
attachment to come off and hit the
operator or bystanders at high speed
and result in serious or fatal injuries.
When using mowing heads
Equip the deflector with the additional
components specified in the instruction
manual.
Use only the deflector with properly
mounted line limiting blade to ensure the
mowing lines are automatically trimmed
to the approved length.
To reduce the risk of injury, always
turn off the engine before adjusting the
nylon line of manually adjustable
mowing heads
Using the unit with over-long nylon
cutting lines reduces the motor's
operating speed. The clutch then slips
continuously and this causes
overheating and damage to important
components (e.g. clutch, polymer
housing components) – and this can
increase the risk of injury from the
cutting attachment rotating while the
engine is idling.
When using metal cutting tools
STIHL recommends the use of original
STIHL metal cutting attachments. They
are specifically designed to match your
model and meet your performance
requirements.
Metal cutting attachments rotate at very
high speed. The forces that occur act on
the machine, the attachment and the
material being cut.
Sharpen metal cutting attachments
regularly as specified.
Unevenly sharpened metal cutting
attachments cause out-of-balance
which can impose extremely high loads
on the machine and increase the risk of
breakage.
Dull or improperly sharpened cutting
edges can put a higher load on the
cutting attachment and increase the risk
of injuryfrom cracked or broken parts.
Inspect metal cutting attachments for
cracks or warping after every contact
with hard objects (e.g. stones, rocks,
pieces of metal). To reduce the risk of
injury, remove burrs and other visible
build-ups of material (use a file) because
they may become detached and be
thrown at high speed during operation.
To reduce the risk
of injuryfrom
thrown objects,
never operate the
unit without the
proper deflector for
the type of cutting
attachment being
used.
Check the work area:
Stones, pieces of metal
or other solid objects can
be thrown and cause per-
sonal injury or damage
the cutting attachment
and property (e.g. parked
vehicles, windows).
