| English
Observe the relevant regulations in your country for the
materials to be worked.
u Prevent dust accumulation at the workplace. Dusts
can easily ignite.
Operation
Starting Operation
u 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.
Reversing the rotational direction (see figure D)
The rotational direction switch 7 is used to reverse the
rotational direction of the machine. However, this is not
possible with the On/Off switch 6 actuated.
Right rotation: For drilling and mixing, push the rotational
direction switch 7 to the left until it stops.
Left rotation: For loosening or mixing, push the rotational
direction
switch 7 to the right until it stops.
Switching On and Off
To start the machine, press the On/Off switch 6 and keep
it pressed.
To lock the pressed On/Off switch 6, press the lock-on
button 5.
To switch off the machine, release the On/Off switch 6 or
when it is locked with the lock-on button 5, briefly press
the On/Off switch 6 and then release it.
To save energy, only switch the power tool on when using it.
Adjusting the Speed
The speed of the switched-on power tool can be variably
adjusted, depending on how far the On/Off switch 6 is
pressed.
Light pressure on the On/Off switch 6 results in a low
rotational speed. Further pressure on the switch results in
an increase in speed.
Work Instructions for Drilling
Use drilling lubricant or cutting oil for cooling and
lubrication, and to avoid overheating or jamming of the
drill bit.
When drilling diameters >10mm, drill a pilot hole with a small
drilling diameter. This allows you to reduce the feed pressure
and the power tool is strained less.
For drilling in metal, use only perfectly sharpened HSS drill
bits (HSS=high-speed steel). The appropriate quality is
guaranteed by the Bosch accessories program.
The machine vice, which is available as an accessory,
enables secure clamping of workpieces. This prevents the
workpiece from turning and any accidents this would cause.
Work Instructions for Mixing
u Do not use the power tool in a stand.
u Avoid splashing around the material being stirred.
Otherwise, you could slip and lose control over the
power tool.

u Avoid continuous operation of the power tool at
reduced speed. Otherwise the motor of the power tool
could overheat.
To release the lock-on button 5, briefly press the on/off
switch 6 and then let it go. This will prevent the power tool
from restarting unintentionally (risk of injury).
Selection of the stirrer paddle is dependent on the material
that is to be stirred.
For materials with low viscosity, e. g. emulsion paint,
varnishes, adhesive, grouting compound, cement slurry,
use a stirrer paddle with a left-hand spiral. The material
is moved from the top downwards in a stirrer paddle with
a left-hand spiral. The stirrer paddle is pushed upwards.
Materials with low viscosity are mixed in a way which
minimises splattering.
For materials with high viscosity, e. g. plaster, concrete,
cement, screed, filler, epoxy resin, use a stirrer paddle with
right-hand spiral. The material is moved from the bottom
upwards in a stirrer paddle with a right-hand spiral. The
stirrer paddle works its way into the mixture. Materials with
high viscosity are mixed thoroughly.
While mixing, move the power tool in an up and down motion.
Clean the stirror paddle after use.
u Store the power tool in a safe place. Ensure that it
cannot fall over. Otherwise, the machine may become
damaged.

Maintenance and Service

Maintenance and Cleaning

u Before any work on the machine itself, pull the
mains plug.
u For safe and proper working, always keep the
machine and ventilation slots clean.
Ensure easy operation of the park rest 16 and clean it
regularly.
When the carbon brushes wear below acceptable service
tolerances, the machine will automatically cut out. The
machine must be sent to customer service for maintenance
(for address, see the "Kundendienst und Kundenberatung"
section.
If the machine should fail despite the care taken in
manufacturing and testing procedures, repair should
be carried out by an after-sales service centre for Bosch
power tools.
In all correspondence and spare parts order, please always
include the 10-digit article number given on the type plate
of the machine.
