Dust/Chip Extraction

Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
Operation

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
When operating the machine with power from
mobile generators that do not have sufficient re-
serve capacity or are not equipped with suitable
voltage control with starting current amplifica-
tion, loss of performance or untypical behavior
can occur upon switching on.
Please observe the suitability of the power gen-
erator being used, particularly with regard to
the mains voltage and frequency.
Bosch Power Tools
Switching On and Off
To start the power tool, press the On/Off switch
2 forward and then down.
To lock-on the pressed On/Off switch 2, push
the On/Off switch 2 further forward.
To switch off the power tool, release the On/Off
switch 2, or when it is locked, briefly press the
On/Off switch 2 and then release it.
Switch Version without Lock-on
(country-specific):
To start the power tool, press the On/Off switch
2 forward and then down.
To switch off the machine, release the On/Off
switch 2.
Check grinding tools before using. The
grinding tool must be mounted properly
and be able to move freely. Carry out a test
run for at least one minute with no load. Do
not use damaged, out-of-centre or vibrating
grinding tools. Damaged grinding tools can
burst and cause injuries.
Restarting Protection
(GWS 22-180 JH/GWS 22-230 JH/
GWS 24-180 JH/GWS 24-230 JH/
GWS 26-180 JH/GWS 26-230 JH)
The restarting protection feature prevents un-
controlled restarting of the machine after an in-
terruption in the power supply.
To restart the operation, switch the On/Off
switch 2 to the Off position and start the ma-
chine again.
Reduced starting current
(GWS 22-180 JH/GWS 22-230 JH/
GWS 24-180 JH/GWS 24-230 JH/
GWS 26-180 JH/GWS 26-230 JH)
The electronic reduced starting current limits
the power consumption when switching the tool
on and enables operation from a 13 ampere
fuse.
Note: When the machine runs at full speed im-
mediately after switching on, the reduced start-
ing current and the restarting protection have
failed. The power tool should be sent immedi-
ately to an after-sales service (for addresses,
see section "After-sales Service and Customer
Assistance".
