2. General safety rules
1. WARNING!
Read and understand all instructions.
Failure to follow all instructions listed below may
result in electric shock, fire and/or serious personal
injury.
SAVE THESE INSTRUCTIONS
2. Work Area
Keep your work area clean and well lit. Cluttered
benches and dark areas 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 bystanders, children and visitors away while
operating a power tool. Distractions can cause you
to lose control.
3. Electrical Safety
Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes
and ordinances.Never remove the grounding prong or
modify the plug in any way.Do not use any adaptor
plugs.Check with a qualified electrician if you are in
doubt as to whether the outlet is properly grounded.If
the tools should electrically malfunction or break down,
grounding provides a low resistance path to carry electricity away from the user.
Applicable only to Class I (grounded) tools.
Avoid body contact with grounded surfaces such as
pipes, radiators, ranges and refrigerators. There is
an increased risk of electric shock if your body is
grounded.
Don’t expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
Do not abuse the cord. Never use the cord to carry
the tools or pull the plug from an outlet. Keep cord
away from heat, oil, sharp edges or moving parts.
Replace damaged cords immediately. Damaged
cords increase the risk of electric shock.
When operating a power tool outside, use an outdoor extension cord marked «W-A» or «W». These
cords are rated for outdoor use and reduce the risk of
electric shock.
4. Personal Safety
Stay alert, watch what you are doing and use common sense when operating a power tool. Do not
use a tool while tired or under the influence of
drugs, alcohol, or medication. A moment of inatten-
tion while operating power tools may result in serious
personal injury.
Dress properly. Do not wear loose clothing or
jewelry. Contain long hair. Keep your hair, clothing,
and gloves away from moving parts. Loose clothes,
jewelry, or long hair can be caught in moving parts.
Avoid accidental starting. Be sure switch is off
before plugging in. Carrying tools with your finger
on the switch or plugging in tools that have the
switch on invites accidents.
Remove adjusting keys or wrenches before
turning the tool on. A wrench or a key that is left
attached to a rotating part of the tool may result in
personal injury.
Do not overreach. Keep proper footing and balance
at all times. Proper footing and balance enables bet-
ter control of the tool in unexpected situations.
Use safety equipment. Always wear eye protection.
Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.
5. Tool Use and Care
Use clamps or other practical way to secure and
support the workpiece to a stable platform. Holding
the work by hand or against your body is unstable
and may lead to loss of control.
Do not force tool. Use the correct tool for your
application. The correct tool will do the job better
and safer at the rate for which it is designed.
Do not use tool if the switch does not turn it on or
off. Any tool that cannot be controlled with the switch
is dangerous and must be repaired.
Disconnect the plug from the power source before
making any adjustments, changing accessories, or
storing the tool. Such preventive safety measures
reduce the risk of starting the tool accidentally.
Store idle tools out of reach of children and other
untrained persons. Tools are dangerous in the hands
of untrained users.
Maintain tools with care. Keep cutting tools sharp
and clean. Properly maintained tools with sharp
cutting edges are less likely to bind and are easier to
control.
Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may
affect the tools operation. If damaged, have the
tool serviced before using. Many accidents are
caused by poorly maintained tools.
Use only accessories that are recommended by the
manufacturer for your model. Accessories that may
be suitable for one tool may become hazardous when
used on another tool.

6. Service
Tool service must be performed only by qualified
repair personnel. Service or maintenance performed
by unqualified personnel could result in a risk of
injury.
When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance
section of this manual. Use of unauthorized parts or
failure to follow Maintenance Instructions may create
a risk of electric shock or injury.
3. Specific safety rules and symbols
Hold tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord.Contact with a “live”
wire will make exposed metal parts of the tool “live” and
shock the operator.
Wear ear protectors when using the tool for extended
periods. Prolonged exposure to high intensity noise can
cause hearing loss.
Personal protective equipment
The user and any other persons in the vicinity must wear
suitable eye protection, a safety helmet, ear protection,
protective gloves and breathing protection.

Position the point of the
chisel approx. 80–100 mm
(3.1–3.9 in) from the edge
of the material.
Chiseling direction
Begin chiseling at an angle
of 70–80° to the concrete
surface, with the tip of the
chisel pointing toward the
edge. Increase the angle to
90°as the chisel penetrates,
thus breaking away material.
-CAUTION-
● Drilling may cause splintering of the
material.
● Splinters may cause injury to parts
of the body and eyes.
● Wear eye protection, protective gloves
and breathing protection if no dust
removal system is used.
-CAUTION-
● The tool and the drilling operation
emit noise.
● Excessive noise may damage the hear-
ing.
● Wear ear protection.
Contact pressure
Contact pressure too low:
Chisel jumps about.
Contact pressure too high:
Lower chiseling performance.
Self-sharpening process
Rotate the chisel in the chuck
at regular intervals (ensures
even wear and assists the
self-sharpening process).
Depth of penetration
Polygon chisels break up
and crush the material even
at considerable depth.
