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
blade 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 injury
from 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 above-mentioned risks
when using a metal cutting attachment,
never use a metal cutting attachment
with a diameter larger than specified. It
must not be too heavy. It must be
manufactured from materials of
adequate quality and its geometry must
be correct (shape, thickness).
To
reduce the risk of injury
, a metal
cutting attachment not manufactured by
STIHL must not be heavier, thicker,
have a different shape or a diameter
larger than the largest metal cutting
attachment approved by STIHL for this
power tool model.
Vibrations
Prolonged use of the power tool may
result in vibration-induced circulation
problems in the hands (whitefinger
disease).
No general recommendation can be
given for the length of usage because it
depends on several factors.
The period of usage is prolonged by:
–
Hand protection (wearing warm
gloves)
–
Work breaks
The period of usage is shortened by:
–
Any personal tendency to suffer
from poor circulation (symptoms:
frequently cold fingers, tingling
sensations).
–
Low outside temperatures.
–
The force with which the handles
are held (a tight grip restricts
circulation).
Continual and regular users should
monitor closely the condition of their
hands and fingers. If any of the above
symptoms appear (e.g. tingling
sensation in fingers), seek medical
advice.
Maintenance and Repairs
Service the machine regularly. Do not
attempt any maintenance or repair work
not described in the instruction manual.
Have all other work performed by a
servicing dealer.
