DESCRIPTION OF THE SYMBOLS
Symbols are used in this manual to attract your attention to possible risks. The
safety symbols and the explanations which accompany them must be perfectly
understood. The warnings themselves do not prevent the risks and can not be a
substitute for proper methods of avoiding accidents.
This symbol, before a safety comment, indicates a precaution, a
warning or a danger. Ignoring this warning can lead to an accident for
yourself or for others. To limit the risk of injury, fire, or electric shock
always apply the recommendations indicated.
Before any use, refer to the corresponding paragraph in the present manual.
Conform to relevant safety standards.
This class II symbol indicates that the product is correctly
insulated. Grounding this machine is therefore unnecessary.
This symbol indicates the requirement of wearing ear protection, eye protection,
respirator and gloves when using the product.
Recycle unwanted materials instead of disposing of them as waste. All
tools, hoses and packaging should be sorted, taken to the local
recycling centre and disposed of in an environmentally safe way.

GENERAL SAFETY INSTRUCTIONS
WARNING! Read all safety warnings and instructions.
Failing to follow the warnings and instructions can result in an electric shock,
a fire and/or a serious injury.
Keep all warnings and all instructions to be able to refer to them later on.
The term “tool” in the warnings refers to your electrical mains powered tool (with power
cord) or your battery operated tool (without power cord).
1 – Safety of the work area
a) Keep the work area clean and well lit. Cluttered and dark areas invite accidents.
b) Do not operate electric tools in explosive atmospheres, for example in the presence
of flammable liquids, gases or dust. Electric tools create sparks that can ignite the dust
or fumes.
c) Keep children and bystanders away while operating the tool. Distractions can cause
you to lose control of the tool.
2 – Electrical safety
a) The electric tool plugs must match the outlet. Never modify the plug in any way. Do
not use adapters with earthed (grounded) tools. Unmodified plugs and matching outlets
will reduce the risk of electric shock.
b) Avoid any body contact with earthed or grounded surfaces such as pipes, radiators,
cookers and refrigerators. There is an increased risk of electric shock if your body is
earthed or grounded.
c) Do not expose tools to rain or wet conditions. Water entering a tool will increase the
risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the
tool. Keep the cord away from heat, lubricants, edges and moving parts. Damaged or
entangled cords increase the risk of electric shock.
e) When using a tool outside, use an extension cable suitable for outside use. Use of a
cord suitable for outside use reduces the risk of electric shock.
f) If use of a tool in a humid location is unavoidable, use a supply protected by a
residual current differential device (RCD). The use of an RCD reduces the risk of
electric shock.

3 – Personal safety
a) Stay alert, watch what you are doing and use common sense when operating the
tool. Do not use the tool when you are tired or under the influence of drugs, alcohol or
medication. One moment of carelessness while using a tool can result in serious
personal injury.
b) Use safety equipment. Always wear eye protection. Safety equipment such as dust
masks, non-slip safety shoes, a hard hat and hearing protection used for appropriate
conditions will reduce personal injuries.
c) Avoid unintentional starting. Make sure that the switch is in the off position before
plugging the tool into the mains and/or fitting the batteries, picking it up or carrying it.
Carrying tools with your finger on the switch or plugging in tools with the switch in the
on position is a cause of accidents.
d) Remove any adjustment key before operating the tool. A key left attached to a
rotating part of the tool can result in personal injury.
e) Do not overreach. Keep a proper position and balance at all times. This enables
better control of the tool in unexpected situations.
f) Dress in a suitable manner. Do not wear loose clothing or jewellery. Keep hair,
clothing and gloves away from moving parts. Loose clothing, jewellery or long hair can
be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection
equipment, make sure that they are connected and used correctly. Using dust
collectors can reduce the dust-related risks.
4 – Use and maintenance of the tool
a) Do not force the tool. Use the correct tool for your application. The correct tool will
do the work better and safer in the conditions for which it was manufactured.
b) Do not use the tool if the switch does not make it possible to change from the
operating condition to stop and vice versa. Any tool which cannot be controlled by the
switch is dangerous and should be repaired.
c) Disconnect the power cord before any adjustment, changing an accessory or before
storing the tool. Such preventive safety measures reduce the risk of starting the tool
accidentally.
d) Keep idle tools out of the reach of children and do not allow persons unfamiliar with
the tool or these instructions to operate it. Tools are dangerous in the hands of
untrained users.
e) Maintain the tool. Check that there is no misalignment or obstruction of the moving
parts, broken parts or any other condition that could affect the operation of the tool. In
the event of damage, have the tool repaired before using it. Many accidents are due to
badly maintained tools.
f) Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting
edges are less likely to bind and are easier to control.
g) Use the tool, accessories and blades etc., in accordance with these instructions,
while taking into account the work conditions and the work to be done. The use of the
tool for operations other than those intended could result in dangerous situations.
5 – Maintenance and service
a) Have the tool serviced by qualified repair personnel using only identical
replacement parts. This will ensure that the safety of the tool is maintained.

Special safety warning
Intended use
TECHNICAL SPECIFICATIONS
Wear ear protectors with impact drills. Exposure to noise can cause hearing loss.
Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.
Hold power tool by 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
could give the operator an electric shock.
WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to cause cancer, birth defects or
other reproductive harm. Some examples of these chemicals are:
- lead from lead-based paints,
- crystalline silica from bricks and cement and other masonry products, and
- arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of
work. To reduce your exposure to these chemicals: work in a well ventilated area,
and work with approved safety equipment, such as those dust masks that are
specially designed to filter out microscopic particles.
The machine is intended for impact drilling in brick, concrete and stone as well as
for drilling in wood, metal and plastic. Machines with electronic control and right/left
rotation are also suitable for screwdriving and thread-cutting.

LIST OF MAIN PART
NOISE/VIBRATION INFORMATION
Measured sound values determined according to EN 60745.
Wear hearing protection!
Vibration total values (triax vector sum) determined according to EN 60745:
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.
An estimation of the level of exposure to vibration should also take into account the
times when the tool is switched off or when it is running but not actually doing the job.
This may significantly 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 patterns.
