GENERAL SAFETY INSTRUCTIONS FOR POW-
ER TOOLS
WARNING! All safety instructions, user man-
uals, images and regulations supplied with
these tools must be read. Failure to follow all
of the following instructions may result in elec-
tric shock, fire, and/or serious personal injury.
All instructions and the user manual must be
kept for future reference.
Safety of working environment
1. The workplace must be kept clean and well lit.
Untidy and dark spaces are often the cause of
accidents.
2. Power tools must not be used in potentially ex-
plosive atmospheres, such as in the presence
of flammable liquids, gases or dust. Power tools
create sparks that can ignite dust or fumes.
3. Children and other persons must be kept away
when using power tools. If the operator is dis-
turbed, he/she may lose control of the opera-
tion.
Electrical safety
1. The plug on the power tool's flexible lead must
match the power outlet. The plug must never
be modified in any way. No socket adapters
may be used with tools that have a protective
earth connection. Plugs and respective sockets
that are rendered unusable will reduce the risk
of electric shock.
2. The operator must not touch grounded ob-
jects, such as pipes, central heating units,
cookers and refrigerators. The risk of electric
shock is greater if your body is connected to
the ground.
3. Power tools must not be exposed to rain, mois-
ture or wetness. If water enters the power tool,
the risk of electric shock increases.
4. The flexible supply must not be used for oth-
er purposes. The power tool must not be car-
ried or pulled by the cord, nor must the plug
be unplugged from the socket. The inlet must
be protected from heat, grease, sharp edges
or moving parts. Damaged or tangled leads
increase the risk of electric shock.
5. If the power tool is used outdoors, an extension
cord suitable for outdoor use must be used. Us-
ing an extension cord for outdoor use reduces
the risk of electric shock.
6. If the power tool is used in a humid environ-

5ENGLISH
ment, a residual current device (RCD) must be
used. Using an RCD reduces the risk of electric
shock.
Safety of persons
1. When using a power tool, the operator must be
careful, pay attention to what he/she is doing,
and concentrate and think clearly. Power tools
must not be used if the operator is tired or un-
der the influence of drugs, alcohol or medica-
tion. Momentary inattention while using a pow-
er tool can result in serious personal injury.
2. Use personal protective equipment. Always
use eye protection. Protective equipment such
as a respirator, non-slip safety shoes, hard hat
and hearing protection, used in accordance
with the working conditions, reduces the risk of
personal injury.
3. Unintentional starting of the machine must be
avoided. Make sure that the switch is in the off
position before plugging in and/or connecting
the battery pack, lifting or carrying the tool.
Carrying a tool with your finger on the switch
or plugging in a tool fork with the switch on can
cause injury.
4. All adjusting tools or wrenches must be re-
moved before turning on the tool. An adjusting
tool or wrench that remains attached to the ro-
tating part of the power tool may result in per-
sonal injury.
5. The operator must only work where he/she can
safely reach. The operator must always main-
tain a stable posture and balance. This will al-
low better control of the power tool in unfore-
seen situations.
6. Dress appropriately. Do not wear loose cloth-
ing or jewellery. The operator must make sure
that his/her hair and clothing are a sufficient
distance away from moving parts. Loose cloth-
ing, jewellery and long hair can be caught in
moving parts.
7. Where equipment is provided for connecting
dust extraction and collection facilities, care
must be taken to ensure that it is connected
and used correctly. The use of such equipment
can reduce hazards caused by dust.
8. The operator must not allow the routine that
results from the frequent use of the tools, to
cause them to become complacent and ignore
the principles of tool safety. Careless activity
can cause serious injuries in a split second.
Use and the maintenance of power tools
1. Power tools must not be overloaded. It is es-
sential to use the correct power tool for the
work being carried out. The correct power tool
will do the work it was designed to do better
and safer.
2. Power tools that cannot be turned on and off
with the switch must not be used. Any power
tool that cannot be operated with the switch is
dangerous and must be repaired.
3. Before making any adjustments, changing ac-
cessories, or storing power tools, unplug the
power tool and/or remove the battery pack
from the power tool if it is removable. These
precautions reduce the risk of accidentally
starting the power tool.
4. Unused power tools must be stored out of
the reach of children. Persons unfamiliar with
the power tool or these instructions must not
be allowed to use the power tool. Power tools
are dangerous in the hands of inexperienced
users.
5. Power tools and accessories must be main-
tained. The adjustment of moving parts and
their mobility must be checked and attention
focused on cracks, broken parts and any other
circumstances that may jeopardize the func-
tion of the power tool. If the tool is damaged,
it must be repaired before use. Many accidents
are caused by poorly maintained power tools.
6. Cutting tools must be kept sharp and clean.
Properly maintained and sharpened cutting
tools are less likely to catch on material or jam
and are easier to control.
7. Power tools, accessories and tool bits etc. must
be used in accordance with these instructions
and in the manner intended for the particular
power tool, taking into account the working
conditions and the work to be carried out. Us-
ing power tools for activities other than those
for which they are designed can lead to dan-
gerous situations.
8. Handles and grip surfaces must be kept dry,
clean and free of grease. Slippery handles and
gripping surfaces mean the tool cannot be
held and controlled in unexpected situations.
Service
1. Power tool repairs must be carried out by qual-
ified personnel using identical spare parts. This
will ensure the same level of safety of the pow-

er tool as before the repair.
USE AND MAINTENANCE OF CORDLESS
TOOLS
1. The tool must only be charged with the charger
specified by the manufacturer. A charger that
may be suitable for one type of battery pack
may present a fire hazard when used with an-
other battery pack.
2. The tool must only be used with a battery pack
that is specifically designed for the tool. The
use of any other battery pack may present a risk
of injury or fire.
3. When the battery set is not used, the battery
pack must be protected from contact with oth-
er metal objects, such as paper clips, coins,
keys, nails, screws or other small metal objects
that can cause one battery contact to come into
contact with another. Short-circuiting the bat-
tery terminals may cause burns or fire.
SAFETY INSTRUCTIONS FOR DRILLS
Safety instructions for all work activities
1. Hearing protection must be worn when ham-
mer drilling. Noise exposure can cause hearing
loss.
2. Additional handle(s) must be used. Loss of con-
trol can cause personal injury.
3. The tool must be fully secured before use. This
tool produces a high output torque and with-
out proper locking against the tool during op-
eration, loss of control may occur, which may
result in personal injury.
4. When performing an operation where the drill-
ing tool may touch a hidden guide or its own
power supply, the power tool must be held
by the insulated gripping surfaces. Contact of
the drilling tool with a "live" wire can cause the
uninsulated metal parts of the power tool to
become "live" and lead to an electric shock to
the user.
Safety instructions when using long drills
1. Never use the machine at speeds higher than
the maximum rated drill speed. At higher
speeds, the drill is likely to bend if it is allowed
to rotate freely without being in contact with
the workpiece, which can result in personal in-
jury.
2. Always start at a low speed with the tip of the
drill touching the workpiece. At higher speeds,
the drill is likely to bend if it is allowed to rotate
freely without being in contact with the work-
piece, which can result in personal injury.
3. Only push in a straight line with the drill and do
not apply excessive pressure. Drills can bend
and crack or cause loss of control, which can
result in personal injury.

BATTERY CHARGE STATUS
You can check the current battery charge by pressing the battery indicator button.
TIPS FOR EFFICIENT BATTERY USE
• Charge the batteries before they are completely discharged.
•If the performance of the machine decreases, stop using it and replace or charge the battery. Using
the machine with the last remaining battery power may damage the battery.
•Do not charge the batteries at high temperatures. The batteries are hot immediately after use.
When such a battery is charged, the chemical structure of the cells degrades, and the battery life is
shortened. Therefore, allow the batteries to cool before charging.
•The batteries can only be charged and used in the temperature range of 5 ° C to 30 °C. There is
a risk of damage to the cells. Always allow the batteries to reach normal temperature.
Note: Failure to follow these instructions can damage the batteries and charger or cause an injury.
