2 Safety Precautions and Working Techniques
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.
Do not work on a ladder or in unstable locations.
When working in open ground and gardens take
special care to avoid harming small animals.
To reduce the risk of electrocution, never operate
this power tool in the vicinity of live wires or
power cables.
Always clean the spray container and hose sys‐
tem before changing to a different plant protec‐
tion product.
As soon as the engine is running, the
power machine generates toxic
exhaust gas. These gases may be
odorless and invisible and may con‐
tain unburned hydrocarbons and ben‐
zene. Never work with the machine in
closed or poorly ventilated rooms.
To reduce the risk of serious or fatal injury from
breathing toxic fumes, ensure proper ventilation
when working in trenches, hollows or other con‐
fined locations.
Stop work immediately if you start suffering from
nausea, headaches, impaired vision (e.g. your
field of vision gets smaller), impaired hearing,
dizziness, or impaired concentration – these
symptoms may possibly be the result of too-high
exhaust gas concentration – Risk of accidents!
Operate your power tool so that it produces a
minimum of noise and emissions – do not run the
engine unnecessarily, accelerate the engine only
when working.
To reduce the risk of fire, do not smoke while
operating or standing near your power tool. Com‐
bustible fuel vapor may escape from the fuel sys‐
tem.
If your power tool 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 – see also
"Before Starting". Check in particular that the fuel
system has no leaks and the safety equipment is
fully operative. Do not continue operating your
power tool if it is damaged. In case of doubt, con‐
tact a dealer.
2.12 After finishing work
Close the valve lever
0458-457-0121-C
Always shut off the engine before taking the
power tool off your back.
After finishing work, put the power tool down on
a level, non-flammable surface. Do not place the
machine near easily flammable materials (e.g.
wood chips, bark, dry grass, fuel) – risk of fire!
Check all parts of the power tool for leaks.
After finishing work, thoroughly clean the power
tool and wash your hands, face and, if neces‐
sary, your clothes.
Keep other persons and animals away from the
areas that have been sprayed and do not walk
on them until the plant protection chemical has
dried.
2.13 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 cir‐
culation (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.
2.14 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 per‐
formed by a servicing dealer.
STIHL recommends that you have servicing and
repair work carried out exclusively by an author‐
ized STIHL servicing dealer. STIHL dealers are
regularly given the opportunity to attend training
courses and are supplied with the necessary
technical information.
Only use high-quality replacement parts in order
to avoid the risk of accidents and damage to the
