Special safety precautions

■ To ensure correct use, please read the complete operating instructions care-
fully before the tool is operated for the first time.
■ All instructions concerning the use of the tool are given also for your own safety!
■ Always keep these operating instructions together with the tool. Ensure that the
operating instructions are with the tool when it is given to other persons.
■ The tool must be held in both hands when in use. Always ensure that you work
from a secure stance.
■ Check that the tool is switched off before plugging the supply cord into the mains
socket.
■ The side handle (3) must always be fitted when the tool is in use.
■ Always guide the supply cord away to the rear of the tool.
■ Always wear goggles, ear protectors and a respiratory protection mask when car-
rying out grinding and cutting work.
■ Wear protective gloves and sturdy footwear.
■ For safety reasons, the disc guard, hand guard and auxiliary handle must always
be fitted when the angle grinder is in use.
■ The O-ring must always be in place on the clamping flange (9).
■ The mounting bore of grinding and cutting discs must fit on the centering collar
of the clamping / mounting flange (9) without any play. Do not use reducers or
adaptors. Before switching on the tool, check that the grinding / cutting disc is fit-
ted correctly and that it can rotate freely.
■ Use only grinding and cutting discs that are approved for use at the maximum per-
mitted no-load speed of the tool.
■ Observe the disc manufacturer's instructions when fitting and using grinding / cut-
ting discs.
■ New grinding/cutting discs should be tested by running the tool with the disc for
at least 30 seconds.
■ Grinding/cutting discs that are damaged, run out of true or vibrate must not be
used.
■ Do not subject grinding / cutting discs to impacts and do not allow the discs to
come into contact with grease.
■ Prevent movement of the workpiece by clamping it securely in place.
■ Do not clamp the tool in a vice.
■ A dust extraction system equipped with a stone dust filter, e.g. the Hilti TDA-VC
40/60 vacuum cleaner, must be used when grinding or cutting stone.
■ The tool may be used for dry grinding / cutting only.
■ Grinding or cutting materials containing asbestos is not permitted.
■ Caution: Take care to avoid concealed electric cables, gas and water pipes. For
example, a metal detector may be used to check the area where the work is to be
carried out.
■ Grinding or cutting metal causes sparks to fly. Ensure that persons are not at risk
as a result. Due to possible fire hazards, ensure that there are no flammable mate-
rials in the immediate vicinity (within the area where sparks fly). Do not use the
tool in areas where there is a risk of explosion.
■ Observe the direction of rotation of the disc. Always hold the tool so that sparks
and dust fly away from the body.
■ Caution: The grinding or cutting disc continues to rotate even after the tool has
been switched off.
■ Do not attempt to brake the grinding / cutting disc by applying lateral pressure after
the tool has been switched off.
■ After a power cut: Switch off the tool and unplug the supply cord.
■ Always switch off the tool before fitting the disc guard or adjusting the guard to a
different position.
■ When fitting discs or insert tools, observe the arrow that indicates direction of rota-
tion.
■ The use of extension cables with multiple sockets permitting the simultaneous use
of several electric tools should be avoided.
