The lock will disengage again if you turn the front sleeve (2)

Screwdriving tools (see figure B)
You should always use a universal bit holder (10) when using
screwdriver bits (9). Only use screwdriver bits that fit the
screw head.
Changing the drill chuck
If your power tool does not have a drill spindle locking mech-
anism, you must have the drill chuck changed by an author-
ised after-sales service centre for Bosch power tools.
The drill chuck must be tightened using a tight-
ening torque of approx. 31–35 Nm.
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
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Setting the Rotational Direction (see figure C)
The rotational direction switch (7) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (6) is being pressed.
1 609 92A 59H | (01.10.2019)
Right rotation: To drill and to drive in screws, press the ro-
tational direction switch (7) through to the left stop.
Left Rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (7) through to the right
stop.
Switching on/off
To start the power tool, press and hold the on/off switch
(6).
Press the lock-on button (5) to lock the on/off switch (6) in
this position.
To switch off the power tool, release the on/off switch (6);
or, if the switch is locked with the lock-on button (5), briefly
press the on/off switch (6) and then release it.
Adjusting the Speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (6) to varying extents.
A light pressure on the on/off switch (6) results in a low rota-
tional speed. Increased pressure on the switch causes an in-
crease in speed.
Practical advice
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Only apply the power tool to the screw/nut when the
u
tool is switched off. Rotating tool inserts can slip off.
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.
Using the drill bit sharpener (accessory), you can effortlessly
sharpen twist drill bits with a diameter of 2.5–10 mm.
Belt clip
You can use the belt clip (4) to hang the power tool on a belt,
for example. You then have both hands free and the power
tool is always at hand.
