ergic reactions and/or respiratory diseases to the ope-
rator or bystanders.
Certain kinds of dust are classified as carcinogenic such
as oak and beech dust especially in conjunction with
additives for wood conditioning (chromate, wood pre-
servative). Material containing asbestos must only be
treated by specialists.
Where the use of a dust extraction device is possible
it shall be used. To achieve a high level of dust collec-
tion, use a suitable vacuum cleaner of the type recom-
mended by Hilti for wood dust and/or mineral dust
together with this tool. Ensure that the workplace is
well ventilated. The use of a dust mask of filter class
P2 is recommended. Follow national requirements for
the materials you want to work with.
■
Before beginning work, check the working area
(e.g. using a metal detector) to ensure that no con-
cealed electric cables or gas and water pipes are pre-
sent
. External metal parts of the machine may become
live, for example, when an electric cable is damaged
accidentally. This presents a serious risk of electric
shock.
■
The machine is not intended for use by children, by
debilitated persons or those who have received no
instruction or training.
■
Children must be instructed not to play with the
machine.
Use of the equipment as directed
■
The D-LP 32/DS-TS 32 hydraulic saw system has
been developed for the technical demolition of steel, con-
crete, stone or brickwork structures in construction and
civil engineering applications. It can be used for wet or
dry sawing (the wet sawing technique is normally used).
Use extending beyond this is considered to be not as
directed and requires to be clarified in advance with the
manufacturer.
■
The hydraulic saw system may be operated only by
specialists trained in concrete cutting techniques, referred
to in the following as “operators”. These persons must
be familiar with the content of these operating instruc-
tions and must have been trained in their safe applica-
tion by a Hilti specialist.
■
National regulations and laws, as well as the operat-
ing instructions and the safety information applicable to
the accessories employed (saw blade, fastening acces-
sories etc.) must be observed.
5.2
■
Use only the accessories recommended in these oper-
ating instructions. The use of other accessories may
result in damage or injury. Use only original Hilti spare
parts.
■
Use only saw blades approved for a cutting speed of
63 m/sec.
Electrical safety precautions
■
Connect the unit only to a power source equipped
with an earth conductor and ground fault circuit break-
er (PRCD). Check that these items are in perfect work-
ing order before operating the equipment.
■
Make sure that the mains voltage corresponds to the
specification given on the rating plate.
■
Protect yourself against electric shock, i.e. avoid con-
tact with earthed components such as pipes, radiators
and the like.
■
Check the condition of all cables and plugs each time
before use.
■
Keep all electric cables, especially their plug con-
nections, in a dry condition. Close the electric sockets
by means of the covers supplied when not in use.
■
Use of extension cables: Use only extension cables
with adequate conductor cross-section which are approved
for the intended field of use. Do not work with extension
cables when they are rolled up. This can result in a drop
in output at the equipment and may cause the cable to
overheat. Replace damaged extension cables.
■
Disconnect the power cable before beginning clean-
ing and maintenance work or in the event of a lengthy
interruption between periods of operation.
■
Any generator used must be earthed when in opera-
tion.
Safety precautions during
transport
■
Make sure that the hydraulic saw system cannot move
about during transportation.
■
Always avoid adopting a bent-over body position
