Dust 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.
– To achieve a high degree of dust extrac-
tion, use the GAS 50 MS vacuum cleaner
for mineral dust together with this power
tool.
– 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.
The vacuum cleaner must be approved for the
extraction of masonry dust. Bosch provides suit-
able vacuum cleaners.
Insert a vacuum hose 4 (accessory) into the vac-
uum connection 2. Connect the vacuum hose 4
to a vacuum cleaner (accessory). An overview
for connecting to a vacuum cleaner can be found
at the end of these instructions.
Notes for the Use of Concrete Grinders
Please observe the following notes in order to re-
duce the dust emissions occurring while working.
– Only use combinations of diamond cutting
discs, concrete grinders with mounted guard
and extraction hood as well as dust category
M vacuum cleaners that are recommended
by Bosch. Other combinations can lead to in-
sufficient dust collection and separation.
– Observe the operating instructions of the vac-
uum cleaner for maintenance and cleaning of
the vacuum cleaner, including the filter. Emp-
ty dust collection containers immediately
once full. Clean the filters of the vacuum
cleaner regularly and always insert the filters
completely into the vacuum cleaner.

– Only use vacuum hoses as intended for by
Bosch. Do not manipulate the vacuum hose.
When rocks or chunks of stone/masonry are
drawn into the vacuum hose, cease work and
clean the vacuum hose immediately. Prevent
the vacuum hose from being bent or creased.
– Use the concrete grinder only as intended for.
– Observe the general requirements for con-
struction sites.
– Provide for good ventilation.
– Ensure that the work area is free of obstruc-
tions. For longer grinding jobs, the vacuum
cleaner must be able to move along freely
and at the right time.
– Wear hearing protection, protective goggles,
dust mask and gloves as required. As dust
mask, use at least a particle-filtering class
FFP 2 half-mask.
– Use a suitable vacuum cleaner for cleaning
the workplace. Prevent settled dust from be-
ing swirled up by sweeping.
Operation

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the type plate of the
power tool.
Switching On and Off
To switch on the machine, push the On/Off
switch 6 forward and press it down at the front
to lock on.
To switch off the machine, press down the
On/Off switch 6 at the rear so that the switch
springs back to the Off position.
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-center or vibrating
grinding tools. Damaged grinding tools can
burst and cause injuries.
