– to be used with suitable tools
recommended by the manufacturer for
this power tool.
Safety instructions for hammers
Wear ear defenders. The effect of noise
may result in loss of hearing.
Use auxiliary handles supplied with
the power tool. The loss of control may
result in injuries.
Hold the power tool by the insulated
gripping surfaces when performing an
operation where the cutting accessory
may contact hidden wiring or its own
cord. Cutting accessory contacting a “live”
wire may make exposed metal parts of the
power tool “live” and shock the operator.
Do not open the battery. Short-circuiting
hazard!
Protect the battery against heat,
including prolonged sunshine, fire, water
and moisture. Explosion hazard!

A damaged or incorrectly used battery may
result in the emission of fumes.
Ensure
a supply of fresh air and consult a doctor in
the event of any physical complications. The
fumes may irritate the respiratory tracts.
Safety instructions for drill machines
Safety instructions for all operations
Wear ear protectors when impact drilling.
Exposure to noise can cause hearing loss.
Use the auxiliary handle(s). Loss of
control can cause personal injury.
Brace the tool properly before use. This
tool produces a high output torque and
without properly bracing the tool during
operation, loss of control may occur
resulting in personal injury.
Hold the power tool by the insulated
gripping surfaces when performing an
operation where the cutting accessory
may contact hidden wiring or its own
cord. Cutting accessory contacting a “live”
wire may make exposed metal parts of the
power tool “live” and shock the operator.
Safety instructions when using long
drill bits
Never operate at higher speed than the
maximum speed rating of the drill bit.
At higher speeds, the bit is likely to bend if
allowed to rotate freely without contacting
the workpiece, resulting in personal injury.

CHE 2-26 18.0-EC
16
Always start drilling at low speed and with
the bit tip in contact with the workpiece.
At higher speeds, the bit is likely to bend if
allowed to rotate freely without contacting
the workpiece, resulting in personal injury.
Apply pressure only in direct line with the
bit and do not apply excessive pressure.
Bits can bend causing breakage or loss of
control, resulting in personal injury.
Additional safety instructions
Use suitable detectors to detect
concealed power supply cables or
consult your local supply company.
Contact with electric cables may result in
a fire and/or electric shock. A damaged
gas pipe may cause an explosion. Cutting
into a water pipe will cause damage to
property or may cause an electric shock.
When working, hold the power tool firmly
with both hands and ensure that you
have a secure footing. The power tool is
controlled more securely if held with both
hands.
Secure the workpiece. A workpiece is
held more securely in a clamping device
than by hand.
Only use tools with SDS-plus tool holder.
Pull on the tool to check that it is locked
properly.
Have a damaged dust cap replaced
immediately. The dust cap prevents the
ingress of dust into the tool holder.

Dust released from materials, such as
lead paints, some types of wood, minerals
and metal, may be hazardous to the
operator or people in the vicinity.
Inhaling
or touching such dust may result in
respiratory diseases and/or allergic
reactions.
– Ensure the workplace is well
ventilated.
– If possible, use external dust
extraction.
– It is recommended to wear a respirator
mask belonging to filter class P2.
Do not work on materials which release
hazardous substances (e.g. asbestos).
Use only original batteries with the
voltage indicated on the type plate of
your power tool. The use of other
batteries, e.g. imitations, reconditioned
batteries or other makes, increases the risk
of injury and damage to property by
exploding batteries.
Recharge batteries only with chargers
recommended by the manufacturer. A
charger that is suitable for one type of
battery may create a fire hazard when used
with another battery.
The battery may be damaged by pointed
objects such as e.g. nails or screwdrivers
or by external application of force. This
may give rise to an internal short circuit,
causing the battery to burn, smoke,
explode or overheat.
Before carrying out any work on the
power tool, move the direction
preselector switch to the middle position.
Operate the direction preselector switch
or torque setting turning dial only when
the tool is stopped.
Identify the power tool with stickers only.
Do not drill any holes into the housing.

Noise and vibration
The noise and vibration values have been
determined in accordance with EN 60745.
The A-weighted noise level of the power tool
is typically:
– Sound pressure level: 90 dB(A);
– Sound power level: 101 dB(A);
– Uncertainty K: 3 dB.
Total vibration value:
– when hammer drilling:
– Emission value ah: 15.9 m/s2
– Uncertainty K: 1.5 m/s2
– when chiselling:
– Emission value ah: 12.7 m/s2
– Uncertainty K: 1.5 m/s2
ATTENTION!
The indicated measurements refer to new
power tools. Daily use causes the noise and
vibration values to change.
NOTE!
The vibration emission level given in this
information sheet has been measured in
accordance with a standardised test given in
EN 60745 and may be used to compare one
tool with another. It may be used for a
preliminary assessment of exposure.
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.
To make an accurate estimation of the
vibration exposure level, it is also necessary to
take into account the times when the tool is
switched off or running but not actually in use.
This may significantly decrease 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.
CAUTION!
Wear ear defenders at a sound pressure
above 85 dB(A).
