Safety Notes
General Power Tool Safety Warnings
WARNING Read all safety warnings and all
instructions. Failure to follow
the warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future
The term “power tool” in the warnings refers to
your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power
tools create sparks which may ignite the
dust or fumes.
c) Keep children and bystanders away
while operating a power tool. Distractions can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
use any adapter plugs with earthed
(grounded) power tools. Unmodified
plugs and matching outlets will reduce
risk of electric shock.
b) Avoid body contact with earthed or
grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is
an increased risk of electric shock if your
body is earthed or grounded.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool
will increase the risk of electric shock.
d) Do not abuse the cord. Never use the
cord for carrying, pulling or unplugging
the power tool. Keep cord away from
heat, oil, sharp edges and moving parts.
Damaged or entangled cords increase the
risk of electric shock.
Bosch Power Tools
e) When operating a power tool outdoors,
use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric
f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use
of an RCD reduces the risk of electric
3) Personal safety
a) Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use a power tool
while you are tired or under the influence of drugs, alcohol or medication. A
moment of inattention while operating
power tools may result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective
equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for appropriate conditions will
reduce personal injuries.
c) Prevent unintentional starting. Ensure
the switch is in the off-position before
connecting to power source and/or battery pack, picking up or carrying the
tool. Carrying power tools with your finger on the switch or energising power
tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench
or a key left attached to a rotating part of
the power tool may result in personal injury.
e) Do not overreach. Keep proper footing
and balance at all times. This enables
better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing
and gloves away from moving parts.
Loose clothes, jewellery or long hair can
be caught in moving parts.
2 609 140 699 | (3.12.09) Page 16 Thursday, December 3, 2009 9:10 AM
16 | English
g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and
properly used. Use of dust collection can
reduce dust-related hazards.
4) Power tool use and care
a) Do not force the power tool. Use the correct power tool for your application. The
correct power tool will do the job better
and safer at the rate for which it was designed.
b) Do not use the power tool if the switch
does not turn it on and off. Any power
tool that cannot be controlled with the
switch is dangerous and must be repaired.
c) Disconnect the plug from the power
source and/or the battery pack from the
power tool before making any adjustments, changing accessories, or storing
power tools. Such preventive safety
measures reduce the risk of starting the
power tool accidentally.
5) Battery tool use and care
a) Recharge only with the charger specified
by the manufacturer. A charger that is
suitable for one type of battery pack may
create a risk of fire when used with another battery pack.
b) Use power tools only with specifically
designated battery packs. Use of any other battery packs may create a risk of injury
and fire.
c) When battery pack is not in use, keep it
away from other metal objects, like paper clips, coins, keys, nails, screws or
other small metal objects, that can make
a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
d) Under abusive conditions, liquid may be
ejected from the battery; avoid contact.
If contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from
the battery may cause irritation or burns.
d) Store idle power tools out of the reach of
children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.
6) Service
e) Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool
repaired before use. Many accidents are
caused by poorly maintained power tools.
Safety Warnings for Screwdriver
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and
are easier to control.
g) Use the power tool, accessories and tool
bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for
operations different from those intended
could result in a hazardous situation.
2 609 140 699 | (3.12.09)
a) Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that
the safety of the power tool is maintained.
f Hold power tool by insulated gripping surfaces, when performing an operation where
the fastener may contact hidden wiring.
Fasteners contacting a “live” wire may make
exposed metal parts of the power tool “live”
and could give the operator an electric
f Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held
more secure than by hand.
f Always wait until the machine has come to
a complete stop before placing it down. The
tool insert can jam and lead to loss of control
over the power tool.
f Do not open the battery. Danger of shortcircuiting.

The declared vibration emission level represents the main applications of the tool. However
if the tool is used for different applications, with
different accessories or poorly maintained, the
vibration emission may differ. This may significantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibration should also take into account the times
when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect
the operator from the effects of vibration such
as: maintain the tool and the accessories, keep
the hands warm, organisation of work patterns.

Changing the Tool (see figure B)
f Before any work on the machine (e. g.,
maintenance, tool change, etc.) as well as
during transport and storage, set the rotational direction switch to the centre position. Unintentional actuation of the On/Off
switch can lead to injuries.
Pull the locking sleeve 3 forward, push the insert tool to the stop into the tool holder 2 and
release the locking sleeve 3 to lock the insert
Use only screwdriver bits with ball catch 1
(DIN 3126-E6.3). Other screwdriver bits 13 can
be used with a universal bit holder with ball
catch 12.
Starting Operation
Inserting the Battery
f Use only original Bosch lithium ion batteries with the voltage listed on the nameplate
of your power tool. Using other batteries can
lead to injuries and pose a fire hazard.
Note: Use of batteries not suitable for the machine can lead to malfunctions of or cause damage to the power tool.
Set the rotational direction switch 8 to the centre position in order to avoid unintentional starting. Insert the charged battery 7 into the handle
so that it can be felt to engage and faces flush
against the handle.
Reversing the Rotational Direction
(see figure C)
Pull the locking sleeve 3 forward and remove the
insert tool.
The rotational direction switch 8 is used to reverse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 9 actuated.
Right rotation: For driving in screws and tightening nuts, press the rotational direction switch
8 through to the left stop.
Method of Operation
The tool holder 2 with the tool is driven by an
electric motor via a gear and impact mechanism.
The working procedure is divided into two phases:
Screwing in and tightening (impact mechanism
in action).
The impact mechanism is activated as soon as
the screwed connection runs tight and thus load
is put on the motor. In this instance, the impact
mechanism converts the power of the motor to
steady rotary impacts. When loosening screws
or nuts, the process is reversed.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 8 through to the right stop.
Switching On and Off
To start the machine, press the On/Off switch 9
and keep it pressed.
The power light 4 lights up when the On/Off
switch 9 is slightly or completely pressed, and
allows the work area to be illuminated when
lighting conditions are insufficient.
To switch off the machine, release the On/Off
switch 9.
Adjusting the Speed
The speed of the switched on power tool can be
variably adjusted, depending on how far the
On/Off switch 9 is pressed.
Light pressure on the On/Off switch 9 results in
a low rotational speed. Further pressure on the
switch results in an increase in speed.

Temperature Dependent Overload Protection
When using as intended for, the power tool cannot be subject to overload. When the load is too
high or the allowable battery temperature range
of 0–70 °C is exceeded, the speed is reduced.
The power tool will not run at full speed until
reaching the allowable battery temperature.
Protection Against Deep Discharging
The lithium ion battery is protected against
deep discharging by the “Electronic Cell Protection (ECP)”. When the battery is empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.
Working Advice
f Apply the power tool to the screw/nut only
when it is switched off. Rotating tool inserts
can slip off.
The torque depends on the impact duration. The
maximum achieved torque results from the sum
of all individual torques achieved through impact. The maximum torque is achieved after an
impact duration of 6–10 seconds. After this duration, the tightening torque is increased only
Screw Applications with Hard, Spring-loaded
or Soft Seat
When in a test, the achieved torques in an impact series are measured and transferred into a
diagram, resulting in the curve of a torque characteristic. The height of the curve corresponds
with the maximum reachable torque, and the
steepness indicates the duration in which this is
A torque gradient depends on the following factors:
– Strength properties of the screws/nuts
– Type of backing (washer, disc spring, seal)
– Strength properties of the material being
screwed/bolted together
– Lubrication conditions at the screw/bolt connection
The following application cases result accordingly:
– A hard seat is given for metal-to-metal screw
applications with the use of washers. After a
relatively short impact duration, the maximum torque is reached (steep characteristic
curve). Unnecessary long impact duration
only causes damage to the machine.
– A spring-loaded seat is given for metal-tometal screw applications, however with the
use of spring washers, disc springs, studs or
screws/nuts with conical seat as well as
when using extensions.
– A soft seat is given for screw applications,
e. g., metal on wood or when using lead
washers or fibre washers as backing.
For a spring-loaded seat as well as for a soft
seat, the maximum tightening torque is lower
than for a hard seat. Also, a clearly longer impact duration is required.
The impact duration is to be determined for
each required tightening torque. The actually
achieved tightening torque is always to be
checked with a torque wrench.
