Stihl FS 80 Instruction Manual page 10

Clean grass and plant residue off the
cutting tool mounting at regular intervals.
If the cutting tool or deflector becomes
clogged or stuck, always turn off the
engine and make sure the cutting tool
has stopped before cleaning.
To reduce the risk of unintentional
engine start and injury, always shut off
the engine and remove the spark plug
boot before replacing the cutting tool.
Never repair damaged or cracked
cutting tools by welding, straightening or
modifying the shape (out of balance).
This may cause parts of the cutting tool
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 standard deflector with the
additional component specified in the
instruction manual.
Use only the deflector with properly
mounted line limiter blade to ensure that
the mowing lines are automatically
trimmed to the approved length.
To reduce the risk of injury, always turn
off the engine before adjusting manually
adjustable mowing heads.
Using the unit with over-long nylon
cutting lines increases the load on the
engine and reduces its operating speed.
This causes the clutch to slip
continuously and results in overheating
and damage to important components
(e.g. clutch, polymer housing
components). There is also a risk of
injury from the cutting tool rotating while
the engine is idling.
When using metal cutting tools
Sharpen metal cutting tools regularly as
specified. Dull or improperly sharpened
cutting edges can put a higher load on
the cutting tool and increase the risk of it
cracking or shattering.
Vibrations
Prolonged use of the unit 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)
– breaks
The period of usage is shortened by:
– Any personal tendency to suffer
from poor circulation (symptoms:
frequently cold fingers, itching).
– Low outside temperatures.
– Gripping force (a tight grip hinders
circulation).
Continual and regular users should
monitor closely the condition of their
hands and fingers. If any of the above
symptoms appear, seek medical advice.
