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.
►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 machine from the broken work
surface.
►Make sure that the working tool is well-
maintained , 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 chuck, drill stell or
drill bit 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.
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.
WARNING Vibration hazard
Using inserted tools that do not fulfil the criteria
mentioned below, will result in a longer time to
complete a task, and may result in higher levels of
vibration exposure. A worn tool will also cause
increased working time.
►Make sure that the inserted tool is well-
maintained, not worn out and of the proper size.
►Always use a sharp tool in order to work
efficiently.
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.
