4.2 Product-specific safety precautions
4.2.1 Personal safety
a) Wear ear protection. Excessive noise may lead to
a loss of hearing.
b) Use the auxiliary handle supplied with the tool.
Loss of control of the tool may lead to injury.
c) To avoid tripping and falling when working, always
lead the sypply cord, extension cord and dust
extraction hose away tho the rear.
4.2.2 Power tool use and care
a) Ensure that the insert tools used are equipped with
the appropriate connection end system and that
they are properly fitted and secured in the chuck
.
b) In the event of a power faillure, switch the tool off
and unplug the supply cord.
This prevents inad-
vertent starting when the power returns.
4.2.3 Electrical safety
a) Before beginning work, check the working area
(e.g. with a metal detector) to ensure that no con-
cealed electric cables or gas and water pipes are
present.
External metal parts of the tool may become
live if, for example, an electric cable is damaged
inadvertenly. This presents a serious risk of elec-
tric shock.
b) Check the condition of the supply cord and its plug
connections and have it replaced by a qualified
electrician if damage is found. Check the condi-
tion of the extension cord and replace it if dam-
age is found.
Do not touch the supply in the event of it suffering
damage while working. Disconnect the supply cord
plug from the socket
. Damaged supply cords and
extension cords present a risk of electric shock.
4.2.4 Work area
a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated. Poor-
ly ventilated workplaces may be injurious to the
health due to exposeure to dust.
4.2.5 Personal protective equipment
The user and any other persons in the vicinity must
wear suitable eye protection, a hard hat, ear protection
and protective gloves when the tool is in use. Breath-
ing protection must be worn if no dust removal sys-
tem is used.
5. Preparation for use
It is essential that the safety precautions print-
ed in these operating instructions are read and observed.
The supply voltage must correspond to the infor-
mation on the type plate.
If extension cords are used: Only extension cords
of a type approved for the intended use and of adequate
cross section may be used. Failure to observe this point
may result in reduced performance of the tool and over-
heating of the cord. Damaged extension cords must be
replaced. The recommended cross-sections and max.
length for extension cords are:

Do not use 1.25 mm 2 and 16 AWG extension cords.
Use only insert tools with TE-Y connection end.
Don’t exert excessive pressure on the tool. This will not
increase its hammering power.
At low temperatures: The tool requires to reach a mini-
mum operating temperature before the hammering
mechanism begins to operate. Switch on the tool and
position the tip of the drill bit or chisel on the work sur-
face. While the tool is running, apply light pressure briefly
and repeatedly until the hammering mechanism begins
to operate.
6. Operation
Operating from generators and transformators
This tool can be used on a generator and jobsite trans-
formators if it meets the following requirements:
– AC output 2600 W minimum
– operating voltage must be 5%/–15% of nom-
inal voltage anytime
– frequency 50–60 Hz; never to exceed 65 Hz
– high dynamic automatic voltage regulator
Do not use other power tools on the generator/trans-
formator at the same time. Switching other tools on/off
can cause undervoltage and/or overvoltage spikes which
could damage the tool.
Inserting the insert tool
a) Unplug the supply cord from the electrical sock-
et to prevent unintentional starting.
