Work calmly and carefully – in daylight conditions
and only when visibility is good. Proceed with
caution, do not put others in danger.
As soon as the engine is running, the
power machine generates toxic
exhaust gas.As soon as the engine is
running, the power machine gener‐
ates toxic exhaust gas. These gases
may be odorless and invisible and
may contain unburned hydrocarbons
and benzene. Never run the engine
indoors or in poorly ventilated loca‐
tions, even if your model is equipped
with a catalytic converter.
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.
Dust, fumes and smoke produced while working
may be hazardous to health. Wear respiratory
protection in case of heavy dust or smoke emis‐
sion.
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.
Never use a power tool that is no longer safe to
operate. In case of doubt, contact a dealer.
Do not operate your power tool in the starting
throttle position – engine speed cannot be con‐
trolled in this position.
To reduce the risk of injury from ejec‐
ted objects, never operate the unit
without the correct deflector for the
type of cutting attachment being
used.
Check the work site – rocks, metal
objects etc. could get caught up and
ejected – potentially beyond a dis‐
tance of 15 m – risk of injury! Such
objects can also damage the cutting
attachment and other property (e.g.
parked vehicles, windows).
Be particularly careful when working on difficult,
densely grown terrain.
When mowing in high shrubbery, under shrub‐
bery and hedges: Hold the cutting tool at a work‐
ing height of at least 15 cm – avoid risks to ani‐
mals.
Always shut off the engine before leaving the
unit unattended.
Examine the cutting attachment periodically at
short intervals and as soon as you note any
noticeable changes:
–
Stop the engine, hold the machine securely,
allow the cutting attachment to come to a stop
–
Check condition and secure fitting; watch out
for cracks
–
Ensure that the cutting blades are sharp
–
Replace damaged or blunt cutting attachments
immediately, even in the event of minor hair‐
line cracks
Clean grass and plant residue off the cutting
attachment mounting at regular intervals –
remove any accumulated material from the cut‐
ting attachment and deflector.
To reduce the risk of injury, shut off the engine
before replacing the cutting attachment.
The gearbox gets hot during opera‐
tion. Never touch the gearbox – risk
of burns!
If a rotating cutting attachment touches a rock or
another hard object, sparks may be generated
which may possibly ignite combustible materials.
Also dried-out plants and brushwood are com‐
bustible, above all in hot and dry weather. If
there is a risk of fire, do not use cutting attach‐
ments in the vicinity of combustible materials,
dried-out plants or brushwood. It is mandatory
that you ask the responsible forestry office about
current fire hazards.
2.8 Using mowing heads
Extend the cutting attachment deflector with the
attached parts specified in the User Manual.
