Angle grinder
– with standard auxiliary handle
Protection class
The specifications apply to a rated voltage [U] of 230 V. These specifications may vary at different voltages and in country-specific models.
Noise/vibration information
Noise emission values determined according to
EN 60745-2-3.
Typically, the A-weighted noise level of the power tool is:
Sound pressure level 93 dB(A); sound power level
104 dB(A). Uncertainty K = 3 dB.
Wear hearing protection
Vibration total values a (triax vector sum) and uncertainty K
h
determined according to EN 60745-2-3:
Surface grinding (roughing):
2 2
a = 6.5 m/s , K = 1.5 m/s ,
h
Grinding with abrasive disc:
2 2
a = 6.0 m/s , K = 1.5 m/s .

The vibration level given in these instructions has been
measured in accordance with a standardised measuring pro-
cedure and may be used to compare power tools. It can also
be used for a preliminary estimation of exposure to vibra-
tion.
The stated vibration level applies to the main applications of
the power tool. However, if the power tool is used for differ-
ent applications, with different application tools or poorly
maintained, the vibration level may differ. This can signific-
antly increase the exposure to vibration over the total work-
ing period.
To estimate the exposure to vibration accurately, the times
when the tool is switched off or when it is running but not ac-
tually being used should also be taken into account. This can
significantly reduce the exposure to vibration over the total
working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping the hands warm,
and organising workflows correctly.
Fitting
Fitting protective equipment
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Note: If the grinding disc breaks during operation or the
holding fixtures on the protective guard/power tool become
damaged, the power tool must be sent to the after-sales ser-
vice immediately; see the "After-Sales Service and Applica-
tion Service" section for addresses.

Protective guard for grinding
clicks into place.
Adjust the position of the protective guard (6) to meet the
requirements of the operation. To do this, push the unlock-
ing lever (1) upward and rotate the protective guard (6) into
the required position.
Always position the protective guard (6) such that all
u
three red cams on the unlocking lever (1) engage in
the corresponding openings on the protective guard
(6).
Adjust the protective guard (6) such that sparking in
u
the direction of the operator is prevented.
The protective guard (6) must only be adjustable
u
while the unlocking lever (1) is actuated. Otherwise,
the power tool must not be used any more under any
circumstances and must be sent to the after-sales ser-
vice.
Note: The coding cams on the protective guard (6) ensure
that only a protective guard that is suitable for the power
tool can be fitted.
Protective guard for cutting
Always use the protective guard for cutting (8) when
u
cutting bonded abrasives.
Provide sufficient dust extraction when cutting stone.
u
The protective guard for cutting (8) is fitted in the same way
as the protective guard for grinding (6).
Extraction guard for cutting with a guide block
The extraction guard for cutting with a guide block (17) is fit-
ted in the same way as the protective guard for grinding (6).
Side handle
Do not operate your power tool without the side
u
handle (5).
Screw the side handle (5) on the left or right of the machine
head depending on how your are working.
