• Take care when carrying out installation work on
the machine, and avoid trapping fingers between
the moving cutting tool and the fixed parts of the
machine.
• Please be particularly careful when mowing on
ground that may subside, on nearby landfills,
trenches and embankments.
• Observe improper maintenance, the use of non-
compliant spare parts, or removal or modification
of the safety devices may result in damage to the
device and serious injury to the person working
with it.
• Use only manufacturer recommended cutting tools
and accessories. The use of other tools and other
accessories may cause injury to the user. Always
keep the lawnmower in good working condition.
• Check the device regularly and make sure before
each use that all start locks and push buttons
function properly.
• Please note that the safety systems or features
of the lawnmower must not be tampered with or
deactivated.
• Note that the user should not modify or manipulate
any sealed engine speed control settings.
• The user must be adequately trained in use,
adjustment and operation (including prohibited
operations).
• It is necessary to take sufficient breaks to reduce
the noise and vibration load.
Residual risks and accident prevention
standards
Neglect of ergonomic principles
Negligent handling of personal protective equip-
ment (PPE)
Negligent handling or ommission of the personal pro-
tective equipment may cause serious injuries.
– Wear prescribed personal protection equipment.
Human behaviour, misbehaviour
– For any work be fully concentrated.
m Residual risks - Cannot be entirely excluded.
Danger from noise
hearing damage
Prelonged unprotected work with the device may
cause hearing damage.
– Always wear ear-muffs.
In case of emergency
In case of a possibly occuring accident take the nec-
essary first aid steps as appropriate and obtain quali-
fied medical aid as quickly as possible.
During longer work, because of vibrations, there is
a risk of circulation problems in the user's hands
(white-finger-syndrome). White-finger-syndrome is
a vascular disease where the small blood vessels in
fingers and toes contract seizure-like. The affected
areas are no longer supplied with blood and there-
fore look very pale.

Frequent use of vibrating machines can cause nerve
damage in people whose circulation is compromised
(e.g. smokers, people with diabetes).
If you notice unusual impairment, immediately stop
the work and consult a doctor. Observe the following
notices in order to reduce risks:
• Keep your body, and particularly your hands, warm
in cold weather.
• Take regular breaks during which you should move
your hands to promote circulation.
• Ensure the lowest possible vibration of the ma-
chine by regularly maintaining it and keeping com-
ponents tight.
