containing asbestos must only be treated by special-
ists. Where the use of a dust extraction device is
possible it shall be used. To achieve a high level
of dust collection, use a suitable vacuum cleaner
of the type recommended 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. Fol-
low national requirements for the materials you
want to work with.
5.3.2 Power tool use and care
a) Hold power tool by insulated gripping surfaces
when performing an operation where the fastener
may contact hidden wiring or its own cord. Fasten-
ers contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the
operator an electric shock.
b) Secure the workpiece. Use clamps or a vice to
secure the workpiece. The workpiece is thus held
more securely than by hand and both hands remain
free to operate the power tool.
c) Check that the insert tools used are compatible
with the chuck system and that they are secured
in the chuck correctly.
5.3.3 Electrical safety
a) Before beginning work, check the working area
(e.g. using a metal detector) to ensure that no
concealed electric cables or gas and water pipes
are present. External metal parts of the power tool
may become live, for example, when an electric cable

6 Operation

CAUTION
Wear protective gloves. The cutting edges of the saw
blade teeth are sharp. The cutting edges may present a
risk of injury.
CAUTION
Wear protective glasses and a dust mask. The sawing
operation swirls up dust and wood chips into the air. The
dust and wood chips may be harmful to the eyes and
respiratory system.
is damaged accidentally. This presents a serious risk
of electric shock.
b) Always lead the supply cord and extension cord
away from the power tool to the rear while work-
ing. This helps to avoid tripping over the cord while
working.
c) Observe local safety regulations concerning con-
necting the tool to a power outlet. Wherever pos-
sible, connect the tool only to a power outlet
equipped with an RCD circuit breaker (ground
fault circuit interruptor).
5.3.4 Work area
a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated. Ex-
posure to dust at a poorly ventilated workplace may
result in damage to the health.
5.3.5 Personal protective equipment
The user and any other persons in the vicinity must
wear suitable eye protection, a hard hat, ear protec-
tion, protective gloves and breathing protection while
the tool is in use.
5.3.6 Protective devices
Do not switch the power tool on if the saw blade,
the blade guard or the pivoting guard are not fitted
correctly.
CAUTION
Wear ear protectors. The power tool and the sawing
operation generate noise. Exposure to noise can cause
loss of hearing.
