WARNING Projectiles
Failure of the work piece, of accessories, or even of
the machine itself may generate high velocity
projectiles. During operating, splinters or other
particles from the working material may become
projectiles and cause personal injury by striking the
operator or other persons. To reduce these risk:
►Use approved personal protective equipment and
safety helmet, including impact resistant eye
protection with side protection.
►Make sure that no unauthorised persons trespass
into the working zone.
►Keep the workplace free from foreign objects.
►Ensure that the work piece is securely fixed.
WARNING Splinters hazard
Using the insertion tool as a hand struck tool can
result in splinters hitting the operator and can cause
personal injury.
►Never use a insertion tool as a hand struck tool.
They are specifically designed and heat-treated
to be used only in a machine.
WARNING Slipping, tripping and falling
hazards
There is a risk of slipping or tripping or falling, for
example tripping on the hoses or on other objects.
Slipping or tripping or falling can cause injury. To
reduce this risk:
►Always make sure that no hose or other object is
in your way or in any other person's way.
►Always make sure you are in a stable position with
your feet as far apart as your shoulders width and
keeping a balanced body weight.
WARNING Motion hazards
When using the machine to perform work-related
activities, you may experience discomfort in the
hands, arms, shoulders, neck, or other parts of the
body.
►Adopt a comfortable posture whilst maintaining
secure footing and avoiding awkward off-balanced
postures.
►Changing posture during extended tasks may help
avoid discomfort and fatigue.
►In case of persistent or recurring symptoms,
consult a qualified health professional.
WARNING Vibration hazards
Normal and proper use of the machine exposes the
operator to vibration. Regular and frequent exposure
to vibration may cause, contribute to, or aggravate
injury or disorders to the operator’s fingers, hands,
wrists, arms, shoulders and/or nerves and blood
supply or other body parts, including debilitating
and/or permanent injuries or disorders that may
develop gradually over periods of weeks, months, or
years. Such injuries or disorders may include damage
to the blood circulatory system, damage to the
nervous system, damage to joints, and possibly
damage to other body structures.
If numbness, persistent recurring discomfort, burning
sensation, stiffness, throbbing, tingling, pain,
clumsiness, weakened grip, whitening of the skin, or
other symptoms occur at any time, when operating
the machine or when not operating the machine, stop
operating the machine, tell your employer and seek
medical attention. Continued use of the machine after
the occurrence of any such symptom may increase
the risk of symptoms becoming more severe and/or
permanent.
Operate and maintain the machine as recommended
in these instructions, to prevent an unnecessary
increase in vibration.
The following may help to reduce exposure to
vibration for the operator:
►Let the tool do the job. Use a minimum hand grip
consistent with proper control and safe operation.
►If the machine has vibration absorbing handles,
keep them in a central position, avoid pressing the
handles into the end stops.
►When the percussion mechanism is activated, the
only body contact with the machine you should
have are your hands on the handle or handles.
Avoid any other contact, for example supporting
any part of the body against the machine or
leaning onto the machine trying to increase the
feed force. It is also important not to keep the start
and stop device engaged while extracting the tool
from the broken work surface.
►Make sure that the inserted tool is well-maintained
(including sharpness, if a cutting tool), not worn
out, and of the proper size. Insertion tools that are
not well-maintained, or that are worn out, or that
are not of the proper size result in longer time to
complete a task (and a longer period of exposure
to vibration) and may result in or contribute to
higher levels of vibration exposure.
►Immediately stop working if the machine suddenly
starts to vibrate strongly. Before resuming the
work, find and remove the cause of the increased
vibrations.
►Never grab, hold or touch the inserted tool when
using the machine.
