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.
Gear Selection, Mechanical
The gear selector 1 can be actuated at stand-
still or when the machine is running. However,
this should not be done while operating at full
load or maximum speed.
Two speed ranges can be preselected with the gear
selector 1.
Gear I:
Low speed range; when working with
stirrer paddels with diameters up to
200 mm.
Gear II:
High speed range; when working with
stirrer paddels with diameters up to
140 mm.
If the gear selector 1 cannot be set to the end position
at standstill, turn the drive spindle with the stirrer pad-
dle a little.
Switching On and Off
To start the machine, press the On/Off switch 6 and
keep it depressed.
Lock the pushed On/Off switch 6
by pushing the lock-on button 7
upward.
To switch off the machine, release the On/Off switch
6 or when it is locked with the lock-on button 7, briefly
press the On/Off switch 6 and then release it.
Adjusting the Speed
The speed of the switched on power tool can be varia-
bly 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.

Operating Instructions
The choice of stirrer paddle depends on the material to
be stirred. For materials with low viscosity, e. g., disper-
sion paint, varnish, adhesions, casting compound,
cement grout, etc., use a stirrer paddle with left-hand
spiral.
For materials with high viscosity, e. g., ready-mixed
plaster, concrete, cement, screed, filler, epoxy resin,
etc., use a stirrer paddle with right-hand spiral.
While mixing, move the power tool in an up and down
motion. Clean the stirror paddle after use.

Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep the
machine and ventilation slots clean.
If the machine should fail despite the care taken in man-
ufacturing 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.
WARNING! Important instructions for connecting
a new 3-pin plug to the 2-wire cable.
The wires in the cable are coloured according to the fol-
lowing code:
Do not connect the blue or brown wire to the earth ter-
minal of the plug.
Important: If for any reason the moulded plug is
removed from the cable of this power tool, it must be
disposed of safely.
