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) 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.
b) 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
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 is damaged
accidentally. This presents a serious risk of electric shock.
5.3.4 Battery use and care
a) Observe the special instructions applicable to the
transport, storage and use of Li-ion batteries.
b) Do not expose batteries to high temperatures or
fire. This presents a risk of explosion.
c) Do not disassemble, squash or incinerate batter-
ies and do not subject them to temperatures over
80°C. This presents a risk of fire, explosion or injury
through contact with caustic substances.

teries (e.g. batteries with cracks, broken parts,
bent or pushed-in and/or pulled-out contacts).

that it is faulty. Place the tool in a location where
it can be kept under observation, well away from
flammable materials, and allow it to cool down.
Contact Hilti Service after the battery has been
allowed to cool.
5.3.5 Work area
a) Ensure that the workplace is well lit.
