these instructions has been measured in accordance
with a standardised measurement procedure specified
in EN 60745 and can be used to compare devices.
Different uses of the device give rise to different
vibration levels and in many cases they may exceed
the values given in these instructions. It is easy to
underestimate the vibration load if the electrical power
tool is used regularly in particular circumstances.
Note: If you wish to make an accurate assessment
of the vibration loads experienced during a particular
period of working, you should also take into account
the intervening periods of time when the device is
switched off or is running but is not actually in use.
This can result in a much lower vibration load over
the whole of the period of working.
1. Workplace safety
a) Keep your working area clean and
well lit. Untidy or poorly lit working areas
can lead to accidents.
b)
Do not work with the device
in potentially explosive environments in which there are
inflammable liquids, gases or dusts.
Electrical power tools create sparks, which can
ignite dusts or fumes.
c)
Keep children and other
people away while you are
operating the electrical tool.
Distractions can cause you to lose control of
the device.
2. Electrical safety
To avoid danger to life from
electric shock:
a)
The mains plug on the device must match
the mains socket. The plug must not
be modified in any way. Do not use
an adapter plug with devices fitted
with a protective earth. Unmodified
plugs and matching sockets reduce the risk of
electric shock.
7 GB/IE
General safety advice for electrical power tools
b) Avoid touching earthed surfaces such
as pipes, radiators, ovens and refrigerators with any part of your body.
There is an increased risk of electric shock if
your body is earthed
c) Keep the device away from rain or
moisture. Water entering an electrical device
increases the risk of electric shock.
d)
device, to hang up the device or to pull
the mains plug out of the mains socket.
Keep the mains lead away from heat,
oil, sharp edges or moving parts of
the device. Damaged or tangled mains leads
increase the risk of electric shock.
e) When working outdoors with an
electrical power tool always use extension cables that are also approved
for use outdoors. The use of an extension
cable suitable for outdoor use reduces the risk
of electric shock.
f) Use a residual current device (RCD)
for protection if operating the electrical power tool in a moist environment
is unavoidable. The use of an RCD reduces
the risk of electric shock.
Do not use the mains lead for
any purpose for which it was
not intended, e.g. to carry the
.
3. Personal safety
a) Remain alert at all times, watch what
you are doing and always proceed
with caution. Do not use the device if
you are tired or under the influence
of drugs, alcohol or medication. One
moment of carelessness when using the device
can lead to serious injury.
b)
personal protective equipment such as dust
masks, non-slip safety shoes, safety helmets or
ear protectors, appropriate to the type of electrical power tool used and work undertaken,
reduces the risk of injury.
Wear personal protective
equipment and always wear
safety glasses. The wearing of
c) Avoid unintentional operation of
the device. Check that the electrical
power tool is switched off before you
connect it to the mains, pick it up or
carry it. Accidents can happen if you carry
the device with your finger on the ON / OFF
switch or with the device switched on.
d) Remove any setting tools or spanners
before you switch the device on. A tool
or spanner left attached to a rotating part of a
device can lead to injury.
e) Avoid placing your body in an un-
natural position. Keep proper footing
and balance at all times. By doing this
you will be in a better position to control the
device in unforeseen circumstances.
f) Wear suitable clothing. Do not wear
loose clothing or jewellery. Keep your
hair, clothing and gloves clear of moving parts. Loose clothing, jewellery or long
hair can become trapped in moving parts.
g) If vacuum dust extraction and collection
devices are fitted do not forget to
that they are properly connected
correctly used. The use of these devices
reduces the hazard presented by dust.
4.
Careful handling and use
check
and
of electrical power tools
a) Do not overload the device. Always
use an electrical power tool that is
intended for the task you are undertaking. By using the right electrical power
tool for the job you will work more safely and
achieve a better result.
b) Do not use an electrical power tool if
its switch is defective. An electrical power
tool that can no longer be switched on and off
is dangerous and must be repaired.
c) Pull the mains plug from the socket
before you make any adjustments
to the device, change accessories
or when the device is put away. This
precaution is intended to prevent you from
unintentionally starting the device.
8 GB/IE
General safety advice for electrical power tools
d) When not in use always ensure that
electrical power tools are kept out of
reach of children. Do not let anyone use
the device if he or she is not familiar
with it or has not read the instructions
and advice. Electrical power tools are danger-
ous
when they are used by inexperienced people.
e) Look after the device carefully. Check
that moving parts are working properly and move freely. Check for any
parts that are broken or damaged
enough to detrimentally affect the
functioning of the device. Have damaged parts repaired before you use
the device. Many accidents have their origins
in poorly maintained electrical power tools.
f) Keep cutting tools clean and sharp.
Carefully maintained cutting tools with sharp
cutting edges are less likely to jam and are
easier to control.
g) Use the electrical power tool, accesso-
ries, inserted tools etc. in accordance
with these instructions and advice, and
the stipulations drawn up for this particular type of device. In doing this,
take into account the working conditions and the task in hand. The use of
electrical power tools for purposes other than
those intended can lead to dangerous situations.
