Notes for the Use of Concrete Grinders
Please observe the following notes in order to
reduce 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
vacuum cleaner for maintenance and cleaning
of the vacuum cleaner, including the filter.
Empty 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
being 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 nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
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-centre or vibrating
grinding tools. Damaged grinding tools can
burst and cause injuries.
Restarting Protection
The restarting protection feature prevents
uncontrolled restarting of the machine after an
interruption in the power supply.
To restart the operation, switch the On/Off
switch 6 to the Off position and start the ma-
chine again.
Note: Check the function of the restarting pro-
tection feature regularly by having the mains
plug pulled during operation and plugged in
again afterwards.
Reduced starting current
The electronic reduced starting current limits the
power consumption when switching the tool on
and enables operation from a 13 ampere fuse.
Constant Electronic Control
Constant electronic control holds the speed
constant at no-load and under load, and ensures
uniform working performance.
