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 machine do the job. Use a minimum
hand grip consistent with proper control and
safe operation. Use the correct feed force on
the machine. Avoid pressing too hard.
►
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 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.
Working 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.
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.
