 Use power tools only with specifically designated
battery 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
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.
 Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally
occurs, flush with water. If liquid contacts eyes, addi-
tionally seek medical help. Liquid ejected from the
battery may cause irritation or burns.
Service
 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.
Hammer Safety Warnings
 Wear ear protectors. Exposure to noise can cause
hearing loss.
 Use auxiliary handle(s), if supplied with the tool. Loss
of control can cause personal injury.
 Hold the tool by the insulated gripping surfaces when
performing operations where the application tool or
the screw could contact hidden wiring or its own power
cord. Contact with a "live" wire will also make exposed
metal parts of the power tool "live" and shock the operator.
Additional Safety and Working Instructions
 Use appropriate detectors to determine if utility lines
are hidden in the work area or call the local utility com-
pany for assistance. Contact with electric lines can lead
to fire and electric shock. Damaging a gas line can lead to
explosion. Penetrating a water line causes property
damage.
 If the application tool should become blocked, switch
the machine off. Loosen the application tool.
 Before switching on the power tool, make sure that the
application tool moves freely. When switching on with a
blocked drilling tool, high torque reaction can occur.
 For drilling without impact in wood, metal, ceramic and
plastic as well as for screwdriving, tools without SDS-plus
are used (e.g., drill bits with cylindrical shank). For these
tools, a keyless chuck or a key type drill chuck are re-
quired.
 Replace a damaged dust protection cap immediately.
The dust protection cap largely prevents the penetration of
drilling dust into the tool holder during operation. When
inserting the tool, pay attention that the dust protection
cap is not damaged.
 The battery supplied is partially charged. To ensure full
capacity of the battery, completely charge the battery in
the battery charger before using your power tool for the
first time.
 Read the operating instructions of the battery charger.

 Check the tight seating of the battery. Two locking
levels are possible.
 Apply the power tool to the screw only when it is
switched off. Rotating tool inserts can slip off.
 Firmly tighten the auxiliary handle, hold the machine
firmly with both hands while working and keep proper
footing and balance at all times. The power tool is guided
more secure with both hands.
 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 con-
tinuous intense sunlight, fire, water, and moisture.
Danger of explosion.
 In case of damage and improper use of the battery,
vapours may be emitted. Ventilate the area and seek
medical help in case of complaints. The vapours can
irritate the respiratory system.
 Use the battery only in conjunction with your Bosch
power tool. This measure alone protects the battery
against dangerous overload.
 The battery can be damaged by pointed objects such as
nails or screwdrivers or by force applied externally. An
internal short circuit can occur and the battery can burn,
smoke, explode or overheat.
 Dust from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health and cause allergic reactions, lead to res-
piratory infections and/or cancer. Materials containing
asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable
for the material.
– 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
materials to be worked.
 Prevent dust accumulation at the workplace. Dust can
easily ignite.
 The quick change chuck is automatically locked. Check the
locking effect by pulling the quick change chuck.
 Inserting SDS-plus Drilling Tools: Check the latching by
pulling the tool.
 When transporting and storing, set the rotational
direction switch to the centre position. Danger of injury
when accidentally actuating the On/Off switch.
 Avoid unintentional switching on. Ensure the On/Off
switch is in the off position before inserting battery
pack. Carrying the power tool with your finger on the
On/Off switch or inserting the battery pack into power
tools that have the switch on invites accidents.
 When switching on with a blocked drilling tool, high
torque reaction can occur.
