General Power Tool Safety Warnings
Read all safety warnings and all in-
structions.Failure to follow thewarnings
and instructions may result in electric shock, fire and/or seri-
ous injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-
operated (corded) power tool or battery-operated (cordless)
power tool.
Work area safety
Keepworkareacleanandwelllit.Clutteredordarkareas
invite accidents.
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.
Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
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.
Waterenteringapowertoolwillincrease theriskofelectric
shock.
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 movingparts. Damaged
or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an exten-
sion cord suitable for outdoor use. Use of a 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
sense when operating a power tool. Do not use a power
toolwhileyouaretired or undertheinfluenceofdrugs,
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-skid safety shoes, hard hat, or hearing protection used
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. Car-
rying power tools with your finger on the switch or energis-
ing power tools that have the switch on invites accidents.
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
Donotforcethepower tool. Use thecorrectpowertool
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
condition that may affect the power tool’s operation. If
damaged,havethepowertoolrepairedbeforeuse.Many
accidents are caused by poorly maintained power tools.
Keepcuttingtoolssharpandclean.Properly maintained
cutting tools with sharpcutting edgesarelesslikelytobind
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.
Service
Haveyourpowertoolservicedbya qualifiedrepair per-
son using only identical replacement parts. This will en-
sure that the safety of the power tool is maintained.
Hammer Safety Warnings
Wear ear protectors. Exposure to noise can cause hear-
ing 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
thescrew could contact hiddenwiringor its own power
cord. Contact with a “live” wire will also make exposed
metalparts of thepower tool “live” andshockthe operator.
Products sold in GB only: Your product is fitted with a
BS 1363/A approved electric plug with internal fuse (ASTA
approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be
cut off and an appropriate plug fitted in its place by an author-
ised customer service agent. The replacement plug should
have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains sock-
et elsewhere.
Productssoldin AUS and NZ only: Use a residual current de-
vice (RCD) with a rated residual current of 30 mA or less.
Additional Safety and Working
Instructions
Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Use appropriate detectors to determine if utility lines

sion. Penetrating a water line causes propertydamage.
Firmly tighten the auxiliary handle, hold the machine
firmly with both hands while working and keep proper
footing and balance at all times. The machine is securely
guided with both hands.
Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
Fordrillingwithoutimpact inwood, metal,ceramicand plas-
tic as well as for screwdriving, tools without SDS-plus are
used (e.g., drills with cylindrical shank). For these tools, a
keyless chuck or a key type drill chuck are required.
Thequick change chuckis automaticallylocked.Check the
locking effect by pulling the quick change chuck.
Inserting SDS-plus Drilling Tools: Check the latching by

Noise/Vibration Information
The measured values of the machine are listed in the table on
page 161.
Noise and vibrational values (vector sum of three directions)
determined according to EN 60745.
The vibration 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 ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or insertion tools or is
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 itis running butnot actually doingthe job.This maysignif-
icantly 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 pat-
terns.
Declaration of Conformity
We declare under our sole responsibility that the product de-
scribed under “Technical Data” is in conformity with the fol-
lowing standards or standardization documents: EN 60745
according to the provisions of the directives 2011/65/EU,
