Hilti PR 2-HS Operating Instructions Manual page 25

b) Stay alert, watch what you are doing and use com-
mon sense when operating the machine. Don't
use the machine when you are tired or under the
influence of drugs, alcohol or medication. A mo-
ment of inattention while operating machines may
result in serious personal injury.
c) Keep laser tools out of reach of children.
d) Failure to follow the correct procedures when open-
ing the tool may cause emission of laser radiation in
excess of class 2 or, respectively, class 3. Have the
tool repaired only at a Hilti service center.
e) Do not operate the tool in explosive atmospheres,
such as in the presence of flammable liquids,
gases or dust. Tools and appliances create sparks
which may ignite the dust or fumes.
f) (Statement in accordance with FCC §15.21):
Changes or modifications not expressly approved
by the manufacturer can void the user's authority to
operate the equipment.
g) Use of setting-up / adjusting devices and equipment
or operating procedures other than those specified in
these instructions may lead to exposure to hazardous
radiation.
h) Check the condition of the tool before use. If the
tool is found to be damaged, have it repaired at a
Hilti service center.
i) Maintain the machine carefully. Check for mis-
alignment or binding of moving parts, breakage
of parts and any other condition that may affect
the machine's operation. If damaged, have the
machine repaired before use. Poor maintenance is
the cause of many accidents.
j) The user must check the accuracy of the tool
after it has been dropped or subjected to other
mechanical stresses.
k) Check the tool before using it for important meas-
uring work.
l) Check the accuracy of the measurements several
times during use of the tool.
m) When the tool is brought into a warm environment
from very cold conditions, or vice-versa, allow it
to become acclimatized before use.
n) If mounting on an adapter, check that the tool is
screwed on securely.
o) Keep the laser exit aperture clean to avoid meas-
urement errors.
p) Although the tool is designed for the tough condi-
tions of jobsite use, as with other optical and elec-
tronic instruments (e.g. binoculars, spectacles,
cameras) it should be treated with care.
q) Although the tool is protected to prevent entry
of dampness, it should be wiped dry each time
before being put away in its transport container.
Keep the electrical contacts dry (protect from rain
r)
or dampness).
s) Use the mains adapter only for connecting to the
mains supply.
t) Check to ensure that the tool and mains adapter
do not present an obstacle that could lead to a
risk of tripping and personal injury.
u) Ensure that the workplace is well lit.
Check the condition of the extension cord and
v)
replace it if damage is found. Do not touch the
mains adapter if the extension cord or mains ad-
apter are damaged while working. Disconnect the
supply cord plug from the power outlet. Damaged
supply cords or extension cords present a risk of
electric shock.
w) Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
x) Do not expose the supply cord to heat, oil or sharp
edges.
Never operate the mains adapter when it is dirty
y)
or wet. Dust (especially dust from conductive ma-
terials) or dampness adhering to the surface of
the mains adapter may, under unfavorable condi-
tions, lead to electric shock. Dirty or dusty tools
should thus be checked at a Hilti service center
at regular intervals, especially if used frequently
for working on conductive materials.
z) Avoid touching the contacts.
5.2.1 Battery tool use and care
a) Do not expose batteries to high temperatures or
fire. This presents a risk of explosion.
b) Do not disassemble, squash or incinerate batter-
ies and do not subject them to temperatures over
75°C. A risk of fire, explosion or injury through con-
tact with caustic substances may otherwise result.
c) Avoid ingress of moisture. Moisture in the interior
of the tool may cause a short circuit and chemical
reactions resulting in burns to the skin or fire.
d) Under abusive conditions, liquid may leak from the
battery. Avoid contact. If contact accidentally oc-
curs, flush with water. In the event of the liquid
coming into contact with the eyes, rinse the eyes
with plenty of water and consult a doctor. Liquid
ejected from the battery may cause irritation or burns.
e) Do not use batteries other than those approved
for use with the applicable tool or appliance. Use
of other batteries or use of the battery for purposes
for which it is not intended presents a risk of fire and
explosion.
Observe the special instructions applicable to the
f)
transport, storage and use of Li-ion batteries.
g) When not in use, keep the battery and the charger
away from paper clips, coins, keys, nails, screws
or other small metal objects that could cause a
short circuit at the battery terminals or the char-
ging contacts. A short circuit at the battery terminals
or charging contacts could result in personal injury
(burns) or fire.
h) Avoid short-circuiting the battery.Before inserting
the battery in the tool, check that the terminals of
the battery and the tool are free from foreign objects.
