Description - Hilti TE 4-A22 Operating Instructions Manual

Before beginning work, check the working area
i)
(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.
j) In accordance with the applications for which it is
designed, the power tool produces a high torque.
Always use the side handle and hold the power
tool with both hands. The user must be prepared
for sudden sticking and stalling of the insert tool.
k) 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.
2.3.2 Careful use of the cordless tool
a) Ensure the switch is in the off position before
inserting battery pack. Inserting the battery pack
into power tools that have the switch on invites
accidents.

3.3 Additional items required for operating the tool
A suitable battery of the specified type (see table in the Technical Data section) and a suitable battery charger from
the C 4⁄36 series. For further information about battery charging, please read the operating instructions for the battery
charger.
3.4 Lithium‑ion battery charge status
The Li-ion battery features a charge status display. The charge status is indicated by the LEDs on the battery during
charging (please refer to the operating instructions for the charger). When the battery is not in use, pressing one of the
battery release buttons or inserting the battery into the power tool causes the battery charge status to be displayed
by the four LEDs for three seconds.
b) Observe the special guidelines applicable to the
transport, storage and use of Li-ion batteries.
c) Do not expose batteries to high temperatures and
keep them away from fire. This presents a risk of
explosion.
d) 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.
e) Use only batteries of the type approved for use
with the applicable power tool. Use of unapproved
batteries or use of the batteries in areas of application
for which they are not approved presents a risk of
fire and explosion.
f) Do not charge or continue to use damaged bat-
teries (e.g. batteries with cracks, broken parts,
bent or pushed-in and/or pulled-out contacts).
g) If the battery is too hot to touch it may be defective.
Place the tool in a location where it can be kept
under observation, well away from flammable ma-
terials, and allow it to cool down. Contact Hilti
Service after the battery has cooled down.
