verse the rotational direction of the machine.
However, this is not possible with the On /Off
switch 4 actuated.
For drilling and driving in
screws, set the rotational
direction CLOCKWISE
To drive out screws, switch

Setting the Torque

Carry out a practical test to determine with which
of the 5 settings of the torque setting ring 1 the
screws are driven flush into the material.
Low setting, e. g., small screws, soft
1
materials.
High setting, e. g., large screws, hard
5
materials.
With the correct setting, the clutch disengages as
soon as the screw is driven flush into the material
or the set torque is reached. Select a higher set-
ting when driving out screws, or set to the "Drill-
ing" symbol. The correct setting is to be deter-
mined by practical testing.
Drilling
Set the torque setting ring 1 to the "Drill-
ing" symbol.
Operating Instructions
Run-On Brake
When releasing the On/Off switch 4 the speed of
the drill chuck is reduced to a stop, thus prevent-
ing the run-on of the tool.
For screwdriving applications, wait until the screw
is flush with the material and then release the
On/Off switch 4. The screw head does not pene-
trate into the material then.

Maintenance and Cleaning

Before any work on the machine itself, re-
move the battery.
For safe and proper working, always keep
the machine and the ventilation slots clean.
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 orders,
please always include the 10-digit order number
given on the nameplate of the machine.
