5 Safety instructions
In addition to the information relevant to safety
provided in the individual sections of these operating
instructions and the information provided in the
operating instructions of whichever type of rotating
laser is being used, the following instructions must
also be strictly observed at all times.
5.1 General safety measures
Do not render safety devices ineffective and do not
remove information and warning notices.
5.2 Proper organization of the workplace
a) Secure the site in which you are taking measure-
ments and take care to avoid directing the beam
towards other persons or towards yourself when
setting up the appliance.
b) When performing alignment work on ladders,
avoid postures to which you are unaccustomed.
Make sure you work from a safe stance and stay
in balance at all times.
c) Ensure that the appliance is set up on a stable,
level surface (not subject to vibration).
d) Only use the appliance within the defined limits.
e) Take care to ensure that no parts of the body are
located under the tripod when the tripod is set up
or in operation.
f) Do not use the tripod as a hoist or lifting aid.
g) Keep children away. Keep other persons away
from the working area.
h) When setting up the tripod in enclosed spaces
(indoor rooms), check the suitability of the floor
on which it stands, as the tripod could gouge
scratches into the floor.
5.2.1 Electromagnetic compatibility
Although the tool complies with the strict requirements of
the applicable directives, Hilti cannot entirely rule out the
possibility of interference to the tool caused by powerful
electromagnetic radiation, leading to incorrect operation.
Check the accuracy of the tool by taking measurements
by other means when working under such conditions
or if you are unsure. Likewise, Hilti cannot rule out the
possibility of interference with other devices (e.g. aircraft
navigation equipment).
5.3 General safety measures
a) Check the condition of the tool before use. If the tool
is found to be damaged, have it repaired at a Hilti
service center.
b) Always keep the PRA 90 threaded rod free from
objects of any kind, including parts of the body or
dirt.
c) Do not put your fingers or other parts of the body
into the tubes of the tripod legs or other points at
which injuries may be caused.
d) Although the appliance is designed for use on job
sites under tough conditions, it should be handled
with care, in the same way as other electrical
appliances.
e) Although the appliance is protected against the
entry of moisture, it should be wiped dry before
being put away in its transport container.
f) Only use the mains adapter for connecting to the
mains supply.
g) Ensure that the appliance and mains adapter do
not present an obstacle that could lead to a risk
of tripping or personal injury.
h) Ensure that the workplace is well lit.
i) Check extension cords at regular intervals and re-
place them 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 present a risk of electric shock.
j) 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.
k) Do not expose the supply cord to heat, oil or sharp
edges.
l) Never operate the mains adapter when it is dirty
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 appli-
ances should thus be checked at a Hilti service
center at regular intervals, especially if used fre-
quently for working on conductive materials.
m) Avoid touching the contacts.
n) Use the carry strap supplied with the tripod to
make it easier to carry the PRA 90. When trans-
