Warning:
The actual vibration emission value encountered while the drill is being used
can deviate from the value stated in the operating instructions or specified by the
manufacturer. This can be caused by the following influencing factors, which should be
observed prior to and also during use:
- Is the tool being used correctly?
- Is the correct type of material being processed?
- Is the tool in proper working order?
- Are the standard handles, and any optional vibration-damping handles, fitted correctly and
sitting tightly with the body of the drill?
If you experience an unpleasant sensation or notice skin discoloration on your hands while using
the drill, stop working immediately. Make sure that you take adequate breaks when working with
the drill. If you fail to take adequate breaks, this can lead to hand-arm vibration syndrome.
You should assess the load/stress based on the work being performed or the way in which the
drill is being used and then schedule breaks accordingly. This allows the physical load/stress to
be significantly reduced throughout the working time. Minimize your vibration exposure risk.
Maintain this drill as per the directions in the operating instructions.
If the drill is to be used frequently, you should contact your dealer and, if expedient, purchase
vibration-damping accessories (handles).
Avoid using the machine at temperatures of 10°C and below. Draft a work plan that allows
exposure to vibration to be limited.

Warning:
A certain degree of noise exposure is unavoidable when using this drill. Schedule
noise-intensive work to be performed during approved and suitable times. Comply with
any rest periods and limit the duration of work to the necessary minimum. Suitable ear
protectors should be worn for your personal protection and the protection of anyone
else in the vicinity.
II. GENERAL SAFETY PRECAUTIONS FOR POWER TOOLS
WARNING:
Read all of the safety precautions and instructions. Failure to observe the safety
precautions and instructions can result in electric shock, fire and/or serious injury.
Keep all safety precautions and instructions in a secure place for future reference.
The term "power tool" used in these safety precautions refers to mains-operated tools
(with a mains cable) and battery-operated tools (without a mains cable).
1) Safety at the workplace
a) Keep your working environment clean and well illuminated. Cluttered or unlit working
environments can result in accidents.
b) Do not operate the power tool in explosive atmospheres where there is a presence of flammable
liquids, gas or dust. Power tools generate sparks which can ignite the dust or fumes.
c) Keep children and bystanders at a safe distance when operating the power tool. Distractions can
make you lose control of the tool.
2) Electrical safety
a) The connecting plug used by the power tool must be suitable for the power socket. The plug
should not be modified in any way. Do not use any adapter plugs in conjunction with earthed
power tools. Unmodified plugs and corresponding power sockets reduce the risk of electric shock.
b) Avoid physical contact with earthed surfaces such as pipes, radiators, cookers and refrigerators.
There is an increased risk of electric shock if your body is earthed.
c) Do not expose power tools to rain or wet conditions. The ingress of water into a power tool
increases the risk of electric shock.
d) Do not use the cable for any purpose other than that for which it is intended; i.e. do not use it to
carry or suspend the power tool or use it to pull the plug from the power socket. Keep the cable
away from heat, oil, sharp edges or moving power tool parts. Damaged or entangled cables
increase the risk of electric shock.
955.1920.246 DDM1 Drilling Machine Manual Multi Language_Layout 1 06/12/2012 10:26 Page 6

7
e) When using a power tool outdoors only use extension cables that are also suitable for outdoor
use. The use of an extension cable which is suitable for outdoor use reduces the risk of electric
shock.
f) If the use of a power tool in a damp environment cannot be avoided, a residual current device
should be used. Use of a residual current device reduces the risk of electric shock.
3) Personal safety
a) Be vigilant, pay attention to what you are doing and use common sense when operating a power
tool. Do not use any power tools if you are tired or under the influence of drugs, alcohol or
medication. A momentary lapse in concentration when operating a power tool can result in serious
injury.
b) Use personal protective equipment and always wear safety glasses. The use of personal protective
equipment such as dust masks, non-slip safety shoes, hard hats and ear protection will reduce the
risk of injury depending on the type and application of the power tool.
c) Prevent the power tool from being started accidentally. Make sure the power tool is switched off
before picking it up, carrying it or connecting it to the mains supply and/or battery pack. If you
carry a power tool with your finger on the switch or connect the tool to the mains supply when it is
switched on, it can result in an accident.
d) Remove any adjusting tools or wrenches before switching on the power tool. A tool or wrench that
is located in a rotating part can result in injury.
e) Avoid adopting an abnormal posture. Make sure you have a secure footing and keep your
balance at all times. Doing this will enable you to maintain better control of the power tool in
unexpected situations.
f) Wear suitable clothing. Do not wear any loose-fitting clothes or jewellery. Keep hair, clothing and
gloves away from moving parts. Loose-fitting clothes, jewellery or long hair can become entangled
in moving parts.
g) If dust extraction and collection equipment can be fitted, make sure it is connected and used
correctly. Use of a dust extraction system can reduce hazards caused by dust.
4) Operating and handling the power tool
a) Do not overload the power tool. Use the appropriate power tool for the job. Using the correct
power tool will enable you to do the job safer and more efficiently in the specified power range.
b) Do not use a power tool if it has a defective switch. A power tool that cannot be switched on or
off is dangerous and must be repaired.
c) Disconnect the plug from the socket and/or remove the battery before making any adjustments,
changing accessories, or storing the power tool. This precaution will prevent the power tool from
starting accidentally.
d) Keep any unused power tools out of the reach of children. This power tool should not be used by
955.1920.246 DDM1 Drilling Machine Manual Multi Language_Layout 1 06/12/2012 10:26 Page 7

8
anyone who is unfamiliar with its operation and operating instructions. Power tools are dangerous if
they are operated by inexperienced users.
e) Treat power tools with care. Check to make sure that moving parts are working properly and do
not jam; also check to see if any parts are broken or damaged in such a way as could impair the
correct functioning of the power tool. Make sure damaged parts are repaired before operating the
machine. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges jam
less and are easier to control.
g) Use the power tool, accessories, bits, etc. in accordance with these instructions. Also take the
working conditions and the work to be conducted into account. Using power tools for applications
other than those intended can result in hazardous situations.
5) Service
a) Your power tool should only be repaired by specialist personnel using original spare parts. Doing
this will ensure the tool retains its safety.
III. Special safety precautions:
Safety precautions for hammer drills
• Wear ear protectors when using hammer drills. Exposure to noise can cause hearing loss.
• Use the side handles supplied with the power tool. Losing control of the power tool can
result in injury.
• Hold the power tool by the insulated handle areas when performing work during
which the insert tool might hit hidden power lines or its own supply cord. Contact a
live wire can energize the metal parts of the power tool and result in an electric shock.
• Only use the speed selector switch when the motor is at a standstill. Attempting to
change the speed while the drill is running can damage the gearbox
• Never use the hammer drill as a screwdriver. Tightening and slackening screws, nuts, etc.
with the hammer drill is prohibited.
• Do not leave the chuck key in the chuck. Before switching on, check that the key is no
longer in the chuck.
• Ensure that the power tool and any person working with it do not come into contact
with water
The tool's supply cord must be disconnected from the socket prior to any adjustments, servicing, or
maintenance. The electrical power rating of your extension cable must at least equal the power
required by the tool.
Check that the mains voltage matches the specifications on the drill's rating plate.
Check the walls and ceilings to prevent damage to any hidden cables.
Never touch the drill's outer housing directly
after drilling. It gets very hot during drilling.
Only use the supplied key housing for
955.1920.246 DDM1 Drilling Machine Manual Multi Language_Layout 1 06/12/2012 10:26 Page 8

attaching the chuck key to the tool. Do not leave the chuck key in the chuck. Before switching on,
check that the key is no longer in the chuck.
IV. Noise and dust emissions
If the noise level is too high, this can cause hearing loss. Ear protectors should therefore be worn
particularly when using the tool in closed rooms/areas.
Dust and splinters can cause eye injuries: you should therefore always wear protective goggles or
glasses.
Dust represents a particular hazard. Wear a face mask to prevent dust from being inhaled.
Always wear a helmet and safety gloves.
Always wear appropriate, tight-fitting protective clothing. Long hair must be tied up and any loose
jewellery removed.
V. Instructions for start-up
1. Connection to the power supply
The tool is suitable for use with an AC power supply in line with the specifications on the rating
plate.
Make sure that the voltage (V) and frequency (Hz) of the drill, as written on the rating plate
and described in the specifications, match the specifications of the mains connection being used.
The drill is double insulated and equipped with a two-core cable with moulded plug.
For extension cables up to a length of 22m, you should use a cable with a cross-section of 2.0mm
Please also adhere to local regulations. For extension cables longer than 22m,you should use the
next thickest cable (one grade higher). Any cables smaller than this will lead to power loss in the
drill and can cause the cable itself to overheat.
2. Hammer drilling into stone and concrete
Drilling dust can either be removed immediately by extraction or caught directly using
corresponding attachments.
Drilling metal, tiles or other smooth surfaces
Use the regular drill setting. If possible, mark the centre of the hole first using a punch to prevent
thedrill bit from slipping. Use coolant to cool the drill bit if necessary. You can find suitable coolant
at good hardware stores. Staff at the store will be able to provide you with advice on how to use
the coolant. Please always follow the instructions given.
Never use the power tool as a screwdriver.
3. Restrictions with regard to ambient conditions
Ensure that the work surface is clean, dry, and well lit and that no combustible or explosive
objects/chemicals are in the direct vicinity.
Prevent any unauthorized persons from touching the drill or the supply cord.
When the drill is not being used, it should be stored in a dry and safe place that is out of reach
and cannot be accessed by unauthorized persons.
