The main handle 24 can be rotated with respect
to the machine housing toward the left or right
in steps of 90°. In this manner, the On/Off
switch can be brought into a more convenient
position for special working situations, e.g., for
cutting operations using the cutting guide with
dust extraction protection guard 21/cut off
stand or for left-handed persons.
Press the handle unlocking button 25 in the di-
rection of the arrow and at the same time turn
the main handle 24 to the requested position
until it latches.
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.
Bosch Power Tools
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.
Switching On and Off
To start the power tool, press the On/Off switch
3 forward and then down.
To lock-on the pressed On/Off switch 3, push
the On/Off switch 3 further forward.
To switch off the power tool, release the On/Off
switch 3, or when it is locked, briefly press the
On/Off switch 3 and then release it.
Switch Version without Lock-on
(country-specific):
To start the power tool, press the On/Off switch
3 forward and then down.
To switch off the machine, release the On/Off
switch 3.
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.
Kickback stop
(GWS 24-180 LVI/GWS 24-230 LVI)
In case of a sudden drop in speed,
e.g., caused by a jammed disc
while cutting, the power supply to
the motor is electronically inter-
rupted.
To restart the operation, switch the On/Off
switch 3 to the Off position and start the ma-
chine again.
Note: When the machine only runs with heavily
reduced speed, the kickback stop feature has
failed. The power tool must promptly be sent to
an after-sales service agent for maintenance; ad-
dresses, see Section „After-sales Service and
Customer Assistance".
