cessories or is poorly maintained, the vibration level and
noise emission value may differ. This may significantly in-
crease the vibration and noise emissions over the total work-
ing period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
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 accessories, keeping their hands warm, and
organising workflows correctly.
Kickback control
If there is a sudden kickback in the power tool,
e.g. jamming in a separating cut, the power
supply to the motor will be interrupted elec-
tronically.
To restart the tool, set the On/Off switch (3) to
the "off" position and then switch the power tool on again.
Restart protection
The restart protection feature prevents the power tool from
uncontrolled starting after the power supply to it has been
interrupted.
Status indicator (LED)
The following tables describes the LED status indicators (2) on the power tool.
Status indicator (LED) (2) Meaning/cause
Green Status OK
Flashing red Power tool has overheated and will switch off. Leave the power tool to cool down. If the
Illuminated red Kickback shutdown,restart protection or over-
load protection has been triggered, the power
tool will switch off.
Assembly
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Fitting protective equipment
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 with clamping lever
Open the clamping lever (11). Place the protective
guard (8) with the coding cam (10) engaging into the coding
groove on the spindle collar until the shoulder of the protect-
ive guard is seated against the flange of the power tool, and

To restart the tool, set the on/off switch (3) to the "off" posi-
tion and then switch the power tool on again.
Note: If the power tool starts up immediately after an inter-
ruption in the power supply, the restart protection feature
has failed.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.
Soft start
The electronic soft start limits the torque when the power
tool is switched on and enables a smooth start-up.
Note: If the power tool runs at full speed immediately after
being switched on, this means that the soft start has failed.
The power tool must be sent to the after-sales service imme-
diately; see the "After-Sales Service and Application Service"
section for addresses.
Run-out brake
The power tool is fitted with the electronic
Bosch Brake System. When it is switched off,
the abrasive tool is brought to a complete stop
within a few seconds. This means that the run-
out time is significantly shorter than for angle
grinders without a run-out brake and enables the power tool
to be set down sooner.
Solution
–
status indicator (LED) lights up green, the
power tool can be switched on again.
Turn the power tool off and on again.
turn the protective guard (8) to the required position. Close
the clamping lever (11).
Adjust the protective guard (8) such that sparking in
u
the direction of the operator is prevented.
The tensioning force of the clamp from the protective
guard (8) can be changed by loosening or tightening the ad-
justment screw (13). Ensure that the protective guard (8) is
fitted securely and check it regularly.
Note: The coding cams on the protective guard (8) ensure
that only a protective guard that is suitable for the power
tool can be fitted.
Protective guard for grinding with locking screw
Place the protective guard (9) on the spindle collar. Adjust
the position of the protective guard (9) to the requirements
of the operation and lock the protective guard (9) with the
locking screw (12).
