Before Use - Hilti TE 7-A Operating Instructions Manual

5.3.3 Cordless tool 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. A risk of fire, explosion or injury through con-
tact with caustic substances may otherwise result.
d) Do not use batteries other than those approved
for use with the applicable power tool or appli-
ance. Use of other batteries or use of the battery for
purposes for which it is not intended presents a risk
of fire and explosion.
e) 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).
f) If the battery gets too hot to touch, this may indicate
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.
5.3.4 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.
5.3.5 Work area safety
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.
c) WARNING: Some dust created by grinding, sand-
ing, cutting and drilling contains chemicals known

6 Before use

6.1 Battery use and care
NOTE
Battery performance drops at low temperatures. Never
use the battery until the cells become fully discharged.
Change to the second battery as soon as a drop in per-
formance is noticed. Recharge the battery immediately
so that it is ready for reuse.
to cause cancer, birth defects, infertility or other
reproductive harm; or serious and permanent res-
piratory or other injury. Some examples of these
chemicals are: lead from lead-based paints, crys-
talline silica from bricks, concrete and other masonry
products and natural stone, arsenic and chromium
from chemically-treated lumber. Your risk from these
exposures varies, depending on how often you do
this type of work. To reduce exposure to these
chemicals, the operator and bystanders should
work in a well-ventilated area, work with ap-
proved safety equipment, such as respiratory pro-
tection appropriate for the type of dust generated,
and designed to filter out microscopic particles
and direct dust away from the face and body.
Avoid prolonged contact with dust. Wear protec-
tive clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth,
eyes, or to remain on your skin may promote absorp-
tion of harmful chemicals.
5.3.6 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.
5.4 Safety in conjunction with the belt adapter
(accessory)
a) Check that the belt adaptor is securely attached
to the belt before beginning work.
b) Take care to ensure that the cord hanging from
the belt adaptor does not catch on anything. Dis-
connect the power tool from the belt adaptor
before laying it down.
Store the battery in a cool, dry place. Never store the
battery where it is exposed to direct sunlight or sources
of heat, e.g. on heaters / radiators or behind a motor
vehicle windscreen. Batteries that have reached the end
of their life must be disposed of safely and correctly to
avoid environmental pollution.
