Starting Operation; Dust/Chip Extraction; Working Advice - Bosch GWX Professional 10-125 Originalbetriebsanleitung

The permissible speed [rpm] or the circumferential speed
[m/s] of the abrasive tools used must at least match the val-
ues given in the table.
It is therefore important to observe the permissible rota-
tional/circumferential speed on the label of the abrasive
tool.

Dust/chip extraction

The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.

Operation

Starting Operation

Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
When operating the power tool using a mobile generator that
does not have sufficient reserve capacity or an adequate
voltage control system with inrush current boost converter,
loss of performance or atypical behaviour may occur upon
switch-on.
Please check the suitability of the power generator you are
using, particularly with regard to the mains voltage and fre-
quency.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Switching on/off
To start the power tool, push the on/off switch (4) forward.
To lock the on/off switch (4) in position, push the on/off
switch (4) forward and down until it clicks into place.
To switch off the power tool, release the on/off switch (4);
or, if the switch is locked, briefly push the on/off switch (4)
backward and down and then release it.
Always check abrasive tools before using them. The
u
abrasive tool must be fitted properly and be able to
move freely. Carry out a test run for at least one
minute with no load. Do not use abrasive tools that are
damaged, run untrue or vibrate during use. Damaged
abrasive tools can burst apart and cause injuries.
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 (4) to the off posi-
tion and then switch the power tool on again.
Starting current limitation
The electronic starting current limitation feature restricts the
power of the power tool when it is switched on and enables
operation using a 16 A fuse.
Constant Electronic Control (GWX 14-125)
The Constant Electronic keeps the speed at no load and un-
der load virtually consistent, guaranteeing uniform perform-
ance.

Working Advice

Pull the plug out of the socket before carrying out any
u
work on the power tool.
