2 Safety Precautions and Working Techniques
2.5.1 When working at heights:
– Always use a lift bucket
– never use the machine while standing on a
ladder
– never work on an insecure support
– Never use the machine with just one hand
Be particularly alert and cautious when wearing
hearing protection because your ability to hear
warnings (shouts, alarms, etc.) is restricted.
Take breaks when you start getting tired or feel‐
ing fatigue – risk of accidents!
Work calmly and carefully – in daylight conditions
and only when visibility is good. Proceed with
caution, do not put others in danger.
The gear head becomes hot during operation. To
reduce the risk of burn injury, do not touch the
gear housing!
If the machine is subjected to unusually high
loads for which it was not designed (e.g., heavy
impact or a fall), always check that it is in good
condition before continuing work - refer also to
the chapter "Before starting work". Make sure the
safety devices are working properly. Never use a
power tool that is no longer safe to operate. In
case of doubt, contact a dealer.
Inspect the hedge and work area to avoid dam‐
aging the cutting blades:
– Remove stones, rocks, pieces of metal and
other solid objects
– Make sure that no sand or stones get between
the cutter blades, e. g., when working close to
the ground
– Take particular care when cutting hedges next
to or against wire fences
Do not touch electric power lines – never cut
through electric power lines – risk of electrocu‐
tion!
Do not touch the cutting blades.while
the engine is running. If the cutting
blades become jammed by thick
branches or other obstructions,
switch off immediately and disconnect
the plug from the power supply before
attempting to free the blades.
If the hedge is very dusty or dirty, spray the cut‐
ting blades with STIHL resin solvent from time to
time during cutting. This will significantly reduce
blade friction, the aggressive effects of sap and
the build-up of dirt particles.
The dust that occurs during operation may be
harmful to health. Wear a dust mask in case of
dust formation.

If the power cord is damaged, imme‐
diately disconnect the plug from the
wall outlet to avoid the risk of electric
shock.
Never jerk the power cord to disconnect it from
the wall outlet. To unplug, grasp the plug, not the
cord.
Avoid damage to the power supply cord. Do not
drive over it, pinch or tug it.
Position the connecting and extension cords cor‐
rectly:
– Do not chafe on edges, pointed or sharp
objects
– don't trap or squeeze the cord in or under
doors or windows
– If cords are twisted – unplug the power tool
and straighten them out
– Always avoid contact with the cutting attach‐
ment
– Always unwind the extension cord completely
from the cable drum to reduce the risk of fire
from overheating.
Before leaving the power tool unattended: Switch
it off and disconnect the plug from the power
supply.
Check the cutting blades at regular short inter‐
vals during operation or immediately if there is a
noticeable change in cutting behavior:
– Switch off the motor; wait until the cutting
blades have come to a standstill; unplug the
power cord
– Check the condition and firm seat, watch out
for fine cracks
– Ensure that the cutting blades are sharp
To replace the cutting blades, switch off the
machine and unplug the power cord. Risk of
injury from the motor starting unintentionally!
Always clean plant residue, chips, leaves and
excess lubricant off the motor – risk of fire!
2.6 After finishing work
Always clean dust and dirt off the machine – do
not use any grease solvents for this purpose.
Spray the cutting blades with STIHL resin sol‐
vent. Run the motor briefly so that the solvent is
evenly distributed.
2.7 Vibrations
Prolonged use of the power tool may result in
vibration-induced circulation problems in the
hands (whitefinger disease).
