Restart Protection; Speed Preselection - Bosch GWS Professional 18V-15 C Notice Originale

32 | English
Grinding thin metal sheets or other materials that tend to easily vibrate with a large surface area can cause the noise emission
value to increase by up to 15 dB. Suitable, heavy damping mats can reduce the increased noise emissions. Increased noise
emissions must be taken into consideration, both for the risk assessment of the noise output and for selecting suitable hearing
protection.
The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure and may be used to com-
pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ap-
plication tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working 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 application tools, keeping their hands warm,
and organising workflows correctly.
Kickback stop
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. The kickback stop indicator(38)
then lights up. When kickback stop is activ-
ated, the status indicator (42) flashes red.
To restart the tool, set the on/off switch (5) / (11) to the
"off" position and then switch the power tool on again.

Speed preselection

(GWS 18V-15 SC / GWS 18V-15 PSC)
In the default setting, 3 speed levels are preset. A special application (Bosch Toolbox App) can be used to program up to 6
speed levels.
If the number of speed levels is changed, the values of the individual levels are adjusted by default. In this case, the speed
level/mode indicator (40) lights up white. When a speed value is programmed individually, the speed level/mode indicator
(40) lights up blue at this speed level (i.e. not according to a default setting). The individual adaptation of speed levels is pos-
-1
sible in steps of 200 min each. Observe the ascending logic of the steps (2 ≥ 1 / 3 ≥ 2 etc).
The information in the tables below describes the preset speeds (default settings) for each programmed number of levels.

Run-out brake
grinders without a run-out brake and enables the power tool
to be set down sooner.

Restart protection

The restart protection feature prevents the power tool from
starting unintentionally after the power supply to it has been
interrupted.
When restart protection is activated, the status indicator
(42) flashes red.
To restart the tool, set the on/off switch (5) / (11) to the
"off" position and then switch the power tool on again.
Impact shutdown
The integrated impact shutdown switches the power tool off
as soon as it hits the floor. The status indicator (42) then
flashes red.
To restart the tool, set the on/off switch (5) / (11) to the
"off" position and then switch the power tool on again.
User interface (see figure E)
(GWS 18V-15 SC / GWS 18V-15 PSC)
The user interface (4) is used to preselect the speed and to
indicate the status of the power tool.

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
