extract the dust. Do not use a domestic vacuum
cleaner for dust extraction. Inhalation of dust is
damaging to health. Ensure sufficient ventilati-
on of the area during work.
y
During work, use certified eye, respiratory tract
and ear protection with a sufficient level of pro-
tection. Consult the sufficient level of protection
at a personal protective equipment store.
VII. General safety
instructions
•
WARNING!
It is necessary to read all the safety instructions,
the user‘s manual, images and regulations supp-
lied with this power tool.
Not adhering to any of the
following instructions may lead to injury by electrical shock,
a fire and/or a serious injury to persons.
All the instructions and the user‘s manual must be
kept for possible future reference.
The term „power tool“ in all hereafter provided warnings is defi-
ned as an tool powered from the power grid (via a power cord) or
a tool powered from a battery (without a power cord / cordless).
1) SAFETY IN THE WORK AREA
a)
The work area needs to be kept clean, tidy,
and well lit.
Untidiness and dark areas in the work
area are sources of accidents.
b)
The power tool must not be used in environments
where there is an explosion hazard, where there
are flammable liquids, gases or dust.
The power
tool generates sparks which could ignite dust or vapours.
c)
When using the power tool, it is necessary to
prevent children and other persons access.
If the user becomes distracted, they may lose control
over the activity being performed.
2) ELECTRICAL SAFETY
a)
The plug on the power cord must correspond
to the power socket outlet. The power plug
must never be modified in anyway. Socket
adapters must not be used with power tools
that have a safety earth grounding connec-
tion.
Power plugs that are not damaged by modifi-
cations and that correspond to the power socket will
limit the danger of injury by electrical shock.
b)
The user‘s body must not come into contact
with grounded objects, such as pipes, central
heating radiators, stoves and refrigerators.
The risk of injury by electrical shock is greater when
your body is in contact with the ground.
c)
Power tools must never be exposed to rain,
moisture or wetness.
The entry of water into the
power tool increases the danger of injury by electri-
cal shock.
d)
The flexible power cord must not be used for
any other purposes. Power tools must not be
carried or pulled by the power cord, nor may
the power plug be disconnected by pulling
on the power cord. The power cord must be
protected against heat, grease, sharp edges
or moving parts.
Damaged or tangled power cords
increase the danger of injury by electrical shock.
e)
If the power tool is used outdoors, an exten-
sion cord suitable for outdoor use must be
used.
Using extension cords designed for outdoor
use, limits the risk of injury by electrical shock.
f)
If the power tool is used in damp areas, it is
necessary to use a power supply protected
by a residual current device (RCD).
The use of
an RCD limits the danger of injury by electrical shock.
The term „residual current device (RCD)“ may be
substituted for by the term „ground fault circuit
interrupter (GFCI)“ or „earth leakage circuit breaker
(ELCB)“.
3) SAFETY OF PEOPLE
a)
When using the power tool, the user must be
attentive and pay attention to what they are
currently doing and must concentrate and
use common sense. The power tool must not
be used when the user is tired or under the
influence of drugs, alcohol or medication.
Momentary inattentiveness when using the power
tool may result in serious injury to persons.
b)
Use personal protective aids. Always wear
eye protection.
Use protective aids, such as
a respirator, safety footwear with anti-slip soles,
hard head cover or hearing protection appropriately
to the work conditions; they reduce the risk of injury
to persons.
VI. Method of work
y
Use protective aids during work, in particular hearing
and eye protection, and a respirator with a filtration
class P2 for protection of the respiratory tract against
dust, and furthermore appropriate gloves.
y
Before starting work, make sure that there are no
utility lines, e.g. electrical, water, gas, steam, etc. in
the chiselled/drilled material, since by damaging these
utility lines injury, explosion or other material damages
may result. To find these lines, use a suitable metal and
electricity detector.
y
Hold the hammer drill with both hands on the grip sur-
faces of the main and additional handle while maintai-
ning a firm and stable body stance, see Fig. 12. Hammer
drills have a powerful action and may thus destabilise
the user. This method of holding the power tool by the
plastic handles reduces the risk of injury by electrical
shock when a hidden electricity conduit is hit.
Fig. 12
y
If it makes sense, secure the workpiece using, for exam-
ple, a clamp or vice so that it cannot spring out and
potentially cause injuries.
CHISELLING
y
The principle of chiselling is based on the gradual destruc-
tion of material by the effect of impacts and insertion of
the wedge of the chisel, and thus it is necessary to perform
grooving and fluting gradually layer by layer.
DRILLING
y
During long lasting drilling into tiles and concrete, it is
possible to cool the drill bit with water. As a result of
large frictional forces, the drill bit heats up significantly
and subsequently becomes blunt. Ensure that water
does not enter into the internal area of the hammer
drill, since this could result in injury by electrical shock.
Put the hammer drill down in a dry place, where there
is no risk of water entering the hammer drill!
y
When drilling holes into metal, lubricate with a drill bit
coolant emulsion, lubricating paste or machine oil.
y
Before putting down the hammer drill, wait until the
work tool stops moving, otherwise a rotating work tool
may trip against something while being put down and
thereby result in loss of control over the power tool.
SAFETY INSTRUCTIONS
FOR THE CORDLESS HAMMER DRILL
1) Safety instructions for all work activity
a)
When drilling with percussion, it is necessary
to wear hearing protection.
Exposure to noise may
result in loss of hearing.
b) It is necessary to use the additional handle.
Loss
of control may result in injuries to persons.
c) When performing activities, where the machi-
ning (work) tool may come into contact with
hidden conduits or its own power cord, hold the
power tool by the insulated holding surfaces.
In the event that the machining tool comes into contact
with a „live“ conduit, the uninsulated metal parts of the
power tool will become live and may result in the user
suffering injury by electrical shock.
2) Safety instructions for using long drill bits
a) Never use the power tool for higher rotation speeds
than the maximum rated rotation speed of the drill
bit.
At higher rotation speeds, it is probable that the drill bit
will bend if allowed to rotate freely without being in contact
with a workpiece, which may lead to injuries to persons.
b) When starting to drill, it is always necessary to
have a low rotation speed and the tip of the drill
bit must be in contact with the workpiece.
At
higher rotation speeds, it is probable that the drill bit will
bend if allowed to rotate freely without being in contact
with a workpiece, which may lead to injuries to persons.
c) It is necessary to push only in the direction of
the drill bit and excessive pressure must not be
applied.
Drill bits may bend and may break or may result
in loss of control, which may lead to injuries to persons.
y
In the event of use that generates a significant
amount of dust such a drilling with percussion,
chipping into masonry, drilling with a diamond
drill bit, use an industrial vacuum cleaner to
