Dust/Chip Extraction

Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation

Starting Operation

Inserting the battery
Note: The use of batteries unsuitable for your power tool can
lead to malfunctions or damage to the power tool.
Set the rotational direction switch (9) to the middle position
to avoid unintentionally switching it on. Insert the charged
battery (6) into the handle until you feel it engage and it is
flush with the handle.
Setting the rotational direction (see figure I)
The rotational direction switch (9) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (10) is being pressed.
Right rotation: To drill and to drive in screws, press the ro-
tational direction switch (9) through to the left stop.
Left Rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (9) through to the right
stop.
Preselecting the Torque
The torque presetting ring (2) can be used to preselect the
required torque in 22 stages. When the correct setting is
used, the bit will be stopped as soon as the screw is driven
flush into the material or as soon as the set torque has been
reached. In position the overload clutch is deactivated,
e.g. for drilling.
When unscrewing screws, it may be advisable to select a
higher setting or the symbol.
Presetting the operating mode (see figure J)
The operating mode preselection ring (3) can be used to
choose between screwdriving, drilling and impact drilling.
In the "impact drilling" position the overload clutch is deac-
tivated and it is constantly at maximum power.
Mechanical gear selection
Only operate the gear selector (4) when the power
u
tool is not in use.
1 609 92A 4SE | (12.04.2019)
You can preselect two speed ranges with the gear selector
(4).
First gear:
Low speed range; for screwdriving or working with a large
drilling diameter.
Second gear:
High speed range; for working with a small drilling diameter.
Always push the gear selector switch as far as it will
u
go. Otherwise, the power tool may become damaged.
Switching on/off
To start the power tool, press and hold the on/off switch
(10).
The worklight (7) lights up when the on/off switch (10) is
lightly or fully pressed, allowing the work area to be illumin-
ated in poor lighting conditions.
The worklight (7) will remain lit for approx. 10 seconds after
the on/off switch (10) has been released.
Adjusting the Speed/Impact Rate
You can adjust the speed/impact rate of the power tool when
it is on by pressing in the on/off switch (10) to varying ex-
tents.
Applying light pressure to the on/off switch (10) results in a
low rotational speed/impact rate. Applying increasing pres-
sure to the switch increases the speed/impact rate.
Fully automatic spindle lock (Auto-Lock)
The drill spindle, and therefore the tool holder, are locked
when the on/off switch (10) is not pressed.
This allows screws to be driven in even when the battery is
discharged and enables the power tool to be used as a
screwdriver.
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or the permitted bat-
tery temperature is exceeded, the electronics of the power
tool will switch off until the temperature returns to within the
optimum operating temperature range.

Practical advice

Only apply the power tool to the screw when the tool
u
is switched off. Rotating application tools can slip off.
After working at a low speed for an extended period, you
should operate the power tool at the maximum speed for ap-
proximately three minutes without load to cool it down.
When drilling into metal, only use sharpened HSS drills (HSS
= high-speed steel) which are in perfect condition. The
Bosch accessory range guarantees appropriate quality.
Before screwing larger, longer screws into hard materials, it
is advisable to pre-drill a pilot hole with the core diameter of
the thread to approx. 2/3 of the screw length.
