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.
►
Participate in health surveillance or monitoring,
medical exams and training programs offered by
your employer and when required by law.
►
When working in cold conditions wear warm
clothing and keep hands warm and dry.
►
The exhaust air is strongly chilled and shall not
make contact with the operator. Always direct the
exhaust air away from hands and body.
See the ”Noise and vibration declaration statement”
for the machine, including the declared vibration
values. This information can be found at the end of
these Safety and operating instructions.
♦
Comply with the recommended air-pressure when
operating the machine. Either higher or lower
air-pressure has the potential of resulting in higher
levels of vibration.
DANGER
Electrical hazard
The machine is not electrically insulated. If the
machine comes into contact with electricity, serious
injuries or death may result.
►
Never operate the machine near any electric wire
or other source of electricity.
►
Make sure that there are no concealed wires or
other sources of electricity in the working area.
WARNING
Concealed object hazard
During operating, concealed wires and pipes
constitute a danger that can result in serious injury.
►
Check the composition of the material before
operating.
►
Watch out for concealed cables and pipes for
example electricity, telephone, water, gas and
sewage lines etc.
►
If the inserted tool seems to have hit a concealed
object, switch off the machine immediately.
►
Make sure that there is no danger before
continuing.
WARNING
Involuntary start
Involuntary start of the machine may cause injury.
►
Keep your hands away from the start and stop
device until you are ready to start the machine.
►
Learn how the machine is switched off in the event
of an emergency.
►
Release the start and stop device immediately in
all cases of power supply interruption.
►
Whenever fitting or removing the insertion tool,
switch off the air supply, bleed the machine by
pressing the start and stop device and disconnect
the machine from the power source.
