Electrical safety
 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.
 Avoidbodycontactwithearthedorgroundedsurfaces,
such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body is
earthed or grounded.
 Do not expose power tools to rain or wet conditions.
Waterenteringapowertoolwillincreasetheriskofelectric
shock.
 Do not abuse the cord. Neveruse 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.
 When operating a power tool outdoors, use an exten-
sioncord suitablefor outdooruse. Use ofa cord suitable
for outdoor use reduces the risk of electric shock.
 If operating a power tool in a damp location is unavoid-
able, use a residual current device (RCD) protected
supply. Use of an RCD reduces the risk of electric shock.
Personal safety
 Stay alert, watch what you are doing and use common
sensewhenoperatinga power tool.Do notuse apower
toolwhileyouaretiredorundertheinfluenceofdrugs,
alcohol or medication. A moment of inattention while op-
erating power tools may result in serious personal injury.
 Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask,
non-skidsafetyshoes,hardhat,orhearingprotectionused
for appropriate conditions will reduce personal injuries.
 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 en-
ergising power tools that have the switch on invites acci-
dents.
 Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a ro-
tating part of the power tool may result in personal injury.
 Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
 Dress properly. Do not wear loose clothing or jewel-
lery. Keep your hair, clothing and gloves away from
moving parts.Loose clothes, jewellery or long hair can be
caught in moving parts.
 If devices are provided for the connection of dust ex-
traction and collection facilities, ensure these are con-
nected and properly used. Use of dust collection can re-
duce dust-related hazards.
Power tool use and care
 Donotforcethepowertool.Usethecorrectpowertool
for your application. The correct power tool will do the
job better and safer at the rate for which it was designed.
 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.
 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.
 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.
 Maintain power tools. Check for misalignment or bind-
ing of moving parts, breakage of parts and any other
conditionthat may affectthe power tool’s operation. If
damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power
tools.
 Keepcuttingtoolssharpandclean.Properly maintained
cuttingtoolswithsharpcuttingedgesarelesslikelytobind
and are easier to control.
 Use the power tool, accessories and tool bits etc. in ac-
cordance 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.
Battery tool use and care
 Recharge only with the charger specified by the manu-
facturer. A charger that is suitable for one type of battery
pack may create a risk of fire when used with another bat-
tery pack.
 Use power tools only with specifically designated bat-
tery packs. Use of any other battery packs may create a
risk of injury and fire.
 When battery pack is not in use, keep it away from oth-
er 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.
 Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally oc-
curs, flush with water. If liquid contacts eyes, addition-
ally seek medical help. Liquid ejected from the battery
may cause irritation or burns.
Service
 Haveyourpowertoolservicedbyaqualifiedrepairper-
son using only identical replacement parts. This will en-
sure that the safety of the power tool is maintained.

Safety Warnings for Screwdriver
 Hold power tool by insulated gripping surfaces, when
performing an operation where the fastener may con-
tacthiddenwiring.Fastenerscontactinga“live”wiremay
make exposed metal parts of the power tool “live” and
could give the operator an electric shock.
 Use auxiliary handle(s), if supplied with the tool. Loss
of control can cause personal injury.
 Hold the machine with a firm grip. High reaction torque
can briefly occur while driving in and loosening screws.
 Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
 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.
 Do not open the battery. Danger of short-circuiting.
Protect the battery against heat, e. g., against
continuous intense sunlight, fire, water, and
moisture. Danger of explosion.
 In case of damage and improper use of the battery, va-
pours may be emitted. Ventilate the area and seek
medical help in case of complaints. The vapours can irri-
tate the respiratory system.
 Use the battery only in conjunction with your Bosch
power tool. This measure alone protects the battery
against dangerous overload.
 Thebatterycanbedamagedbypointedobjectssuchas
nails or screwdrivers or by force applied externally. An
internal short circuit can occur and the battery can burn,
smoke, explode or overheat.

Assembly
Battery Charging
Note: The battery supplied is partially charged. To ensure full
capacity of the battery, completely charge the battery in the
batterychargerbeforeusingyourpowertoolforthefirsttime.
The lithium-ion battery can be charged at any time without re-
ducing its service life. Interrupting the charging procedure
does not damage the battery.
The lithium-ion battery is protected against deep discharging
by the “ElectronicCell Protection(ECP)”.Whenthe battery is
empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.
 Do not continue to press the On/Off switch after the
machine has been automatically switched off. The bat-
tery can be damaged.
Observe the notes for disposal.
Removing the battery
The battery 4 is equipped with two locking levels that should
prevent the battery from falling out when pushing the battery
unlocking button 5 unintentionally. As long as the battery is
inserted in the power tool, it is held in position by means of a
spring.
To remove the battery 4, press the unlocking button 5 and
pull out the battery toward the front. Do not exert any force.
Changing the Tool (see figure A)
 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
 Regularly clean the power tool’s air vents. The motor’s
fan will draw the dust inside the housing and excessive ac-
cumulation of powdered metal may cause electrical haz-
ards.
 When working with an application tool, pay attention
that the application tool is connected securely on the
tool holder. When the application tool is not securely con-
nected with the tool holder, it can come off during applica-
tion.
Slide the application tool 10 onto the square drive of the tool
holder 1.
With this system, there will be a slight amount of play around
the application tool 10 after connecting securely to the tool
holder 1; this has no influence on the function/safety.
Operation
Method of Operation
The tool holder 1 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
connectionrunstightandthusloadisputonthemotor.Inthis
instance, the impact mechanism converts the power of the
motor to steady rotary impacts. When loosening screws or
nuts, the process is reversed.
Starting Operation
To save energy, only switch the power tool on when using it.
Inserting the battery
Set the rotational direction switch 6 to the centre position to
protect the power tool against accidental starting.

Reversing the rotational direction (see figure B)
The rotational direction switch 6 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 7 actuated.
Right rotation: For driving in screws and tightening nuts,
press the rotational direction switch 6 through to the left
stop.
Left rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 6 through to the
right stop.
Switching On and Off
To start the machine, press the On/Off switch 7 and keep it
pressed.
To switch off the machine, release the On/Off switch 7.
Adjusting the Speed
The speed of the switched-on power tool can be variably ad-
justed, depending on how far the On/Off switch 7 is pressed.

Working Advice
 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 dura-
tion, the tightening torque is increased only minimally.
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.
Screw Applications with Hard, Spring-loaded or Soft Seat
A test in which the achieved torques in an impact series are
measuredandtransferredtoadiagramwillproducethecurve
of a torque characteristic. The height of the curve corre-
sponds with the maximum reachable torque, and the steep-
ness indicates the duration in which this is achieved.
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 du-
ration, the maximum torque is reached (steep characteris-
tic curve). Unnecessary long impact duration only causes
damage to the machine.
– A spring-loaded seat is given for metal-to-metal screw ap-
plications, 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
woodorwhenusingleadwashersorfibrewashersasback-
ing.
For a spring-loaded seat as well as for a soft seat, the maxi-
mum tightening torque is lower than for a hard seat. Also, a
clearly longer impact duration is required.

Tips
Beforescrewinglarger,longerscrewsintohardmaterials,itis
advisable to predrill a pilot hole with the core diameter of the
thread to approx. 2
/3 of the screw length.
Note: Pay attention that no metal particles enter the power
tool.
Belt Clip
With the belt clip 3, the machine can be hung onto a belt. The
user has both hands free and the machine is always at hand.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Store the battery only within a temperature range between
–20 °Cand50 °C. As anexample,donotleave thebattery in
the car in summer.
