Grinding thin metal sheets or other materials that tend to easily vi-
brate 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 ac-
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.
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 and restart
protection mechanisms have failed. The power tool must be
sent to the after-sales service immediately; see the "After-
Sales Service and Application Service" section for ad-
dresses.
Restart protection
The restart protection feature prevents the power tool from
uncontrolled starting after the power supply to it has been
interrupted.
To restart the tool, set the on/off switch (3) to the "off" posi-
tion and then switch the power tool on again.
In rare cases, certain interference pulses can cause the re-
start protection to activate. In such cases, the power tool
switches off and stays switched off. The power tool can be
started up again by releasing the on/off switch (3) and
pressing it again.
Constant Electronic control
GWS 1400 C / GWS 1400 / GWS 14-125
The Constant Electronic keeps the speed at no load and un-
der load virtually consistent, guaranteeing uniform perform-
ance.

Fitting Protective Equipment
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
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
Place the protective guard (7) onto
the holder on the power tool until the
coding cams of the protective guard
are aligned with the holder. When do-
ing so, press and hold the unlocking
lever (1).
Press the protective guard (7) onto
the spindle collar until the shoulder of
the protective guard is sitting on the
flange of the power tool and rotate the
protective guard until it audibly clicks
into place.
Adjust the position of the protective guard (7) to meet the
requirements of the operation. To do this, push the unlock-
ing lever (1) upward and rotate the protective guard (7) into
the required position.
Always position the protective guard (7) such that the
u
two cams on the unlocking lever (1) engage in the
corresponding openings on the protective guard (7).
Adjust the protective guard (7) such that sparking in
u
the direction of the operator is prevented.
The protective guard (7) must only be able to be ro-
u
tated in the direction of the accessory while the un-
locking lever (1) is actuated. Otherwise, the power
tool must not be used any more under any circum-
stances and must be sent to the after-sales service.
Note: The coding cams on the protective guard (7) ensure
that only a protective guard that is suitable for the power
tool can be fitted.
Extraction guard for sanding
For low-dust grinding of paints, lacquers and plastics in con-
junction with carbide grinding heads (11), you can use the
extraction guard (6). The extraction guard (6) is not suitable
for machining metal.
A suitable Bosch dust extractor can be connected to the ex-
traction guard (6). To do so, insert the vacuum hose with
dust extraction adapter into the provided receiving connec-
tion of the extraction guard.
