To avoid the risk of injury, use only genuine Hilti accessories and insert tools.
Observe the information printed in the operating instructions concerning operation, care and maintenance.
Take the influences of the surrounding area into account. Do not use the appliance where there is a risk of fire or
explosion.
Modification of the tool is not permissible.
2.2 Features
Thetoolmakesitpossibleforasinglepersontoleveloraligninanyplanequickly and with great accuracy.
The tool levels itself automatically after switching on. The laser beam is switched on only when the specified accuracy
has been achieved.
LEDs indicate the current operating status.
The tool is powered by a rechargeable Li‑ion battery which can be charged while the tool is in operation.
2.3 Digital distance measurement display
The laser receiver displays digitally the distance between the laser plane and the marking notch on the laser receiver.
This allows the user to determine the exact position of the receiver relative to the laser plane, with millimeter accuracy,
inasingleoperation.
2.4 Horizontal plane
After switching on, the tool levels itself automatically by way of two built-in servo motors.
2.5 Inclined plane (manual alignment in the desired plane of inclination)
The desired inclination can be set with the aid of the PRA 79 slope adapter. For further information on using the slope
adapter, please refer to the instruction sheet supplied with the PRA 79.
2.6 Shock warning
The shock warning function is activated two minutes after the tool has leveled itself after switching on. If a button
is pressed within these two minutes, the two-minute delay begins again. The tool switches to warning mode if it is
brought out of level while in operation (due to vibration or an impact); all LEDs begin to blink and the laser switches
off (the head stops rotating).
2.7 Automatic cut-out
The laser does not switch on and all LEDs blink if the tool is set up outside its self-leveling range (±5°) or if movement
is blocked mechanically. The tool can be set up on a tripod with a 5/8" thread or stood directly on some other steady
surface (free of vibration). When automatic leveling is activated for one or both axes, the built-in servo system ensures
that the specified accuracy is maintained. The tool switches itself off when automatic leveling cannot be achieved (tool
set up outside its leveling range or physical impediment of the mechanism) or when knocked off level (see “Shock
warning” section).
NOTE
If the correct level cannot be achieved, the laser switches itself off and all LEDs blink.

not remove information and warning notices.
en
6
Printed: 29.11.2013 | Doc-Nr: PUB / 5142563 / 000 / 02
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. Amo-
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 mea-
suring 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 mea-
surement errors.
p) Although the tool is designed for the tough con-
ditions of jobsite use, as with other optical and
electronic instruments (e.g. binoculars, specta-
cles, 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.
r) Keep the electrical contacts dry (protect from rain
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.
v) Check the condition of the extension cord and re-
place it if damage is found. Do not touch the mains
adapter if the extension cord or mains adapter 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.
y) 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 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.
f) Observe the special instructions applicable to the
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 charg-
ing 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.
en
7
Printed: 29.11.2013 | Doc-Nr: PUB / 5142563 / 000 / 02
Short-circuiting the battery terminals presents a risk
of fire, explosion or contact with caustic substances.
i) 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).
j) Use only the PUA 81 AC adapter, PUA 82 motor
vehicle power adapter or other chargers recom-
mended by the manufacturer to power the tool or
charge the battery. Failure to observe these points
may result in damage to the tool. Use of a charger
with batteries other than the specific type(s) for which
it is designed presents a risk of fire.
5.3 Proper organization of the work area
a) Secure the area in which you are working and
take care to avoid directing the beam towards
other persons or towards yourself when setting
up the tool.
b) Avoid unfavorable body positions when working
from ladders. Make sure you work from a safe
stance and stay in balance at all times.
c) Readings taken in the vicinity of reflective objects or
surfaces, through panes of glass or similar materials
may produce incorrect results.
d) Ensure that the tool is set up on a steady, level
surface (not subject to vibration).
e) Use the tool only within its specified limits.
f) When working in charging during operation”
mode, attach the AC adapter in a secure posi-
tion, e.g. on a tripod.
g) Use of products for applications different from those
intended could result in hazardous situations. Use
the product and its accessories etc. in accor-
dance with these instructions and in the manner
intended for the particular type of product. Take
the working conditions and the work to be per-
formed into account.
h) Use of the telescopic staff in the vicinity of over-
head high voltage cables is not permissible.
5.3.1 Electromagnetic compatibility
NOTE
OnlyforKorea:Thisdeviceissuitablefortheelectromag-
netic radiation encountered in residential environments
(Class B). It is intended mainly for use in residential envi-
ronments but may also be used in other environments.
Although the tool complies with the strict requirements
of the applicable directives, Hilti cannot entirely rule out
the possibility of the tool being subject to interference
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

5.3.2 Laser classification for Laser Class 2/Class II
tools
Depending on the version purchased, the tool com-
plies with Laser Class 2 in accordance with IEC825-
1:2007/EN60825-1:2007 and Class II in accordance with
CFR 21 § 1040 (FDA). This tool may be used without need
for further protective measures. The eyelid closure reflex
protects the eyes when a person looks into the beam un-
intentionally for a brief moment. This eyelid closure reflex,
however, may be negatively affected by medicines, alco-
hol or drugs. Nevertheless, as with the sun, one should
not look directly into sources of bright light. Do not direct
the laser beam toward persons.

8 Care and maintenance
8.1 Cleaning and drying
1. Blow dust off exit windows.
2. Donottouchtheglasswiththefingers.
3. Use only a clean, soft cloth for cleaning. If necessary,
moisten the cloth slightly with pure alcohol or a little
water.
NOTE Abrasive cleaning materials may scratch the
glass and impair the accuracy of the laser tool.
NOTE Do not use any other liquids as these may
damage the plastic components.
4. Dry the equipment, observing the maximum tem-
peratures given in the technical data.
NOTE Especially in summer and winter, take care
that the given maximum and minimum temperatures
are not exceeded, e.g. when the equipment is stored
in a motor vehicle.
8.2 Care of the Li-ion battery
NOTE
A conditioning charge (as is required with NiCd or NiMH
batteries) is not necessary with Li-ion batteries
NOTE
Interruption of the charging procedure has no negative
effect on battery life.
NOTE
Charging can be started at any time with no negative
effect on battery life. There is no memory effect (as with
NiCd or NiMH batteries).
NOTE
For best results, batteries should be stored fully charged
in a cool dry place. Storing the battery in places subject
to high ambient temperatures (e.g. at a window) has an
adverse effect on battery life and increases the rate of
self-discharge.
NOTE
Batteries lose capacity due to aging and overstressing.
They can then no longer be fully charged. You may
continue to work with a battery that shows signs of
aging, but the battery should be replaced in good time.
1. Avoid ingress of moisture.
2. Charge the battery fully before using it for the first
time.
3. Charge the battery as soon as its performance be-
gins to drop significantly.
NOTE Recharging in good time will increase the
service life of the battery.
NOTE If use of the tool continues, further battery
discharge will be stopped automatically before the
battery cells suffer damage.
4. Charge the battery with the Hilti charger approved
for use with Li-ion batteries.
8.3 Storage
1. Remove the appliance from its case if it has be-
come wet. Dry and clean the tool, its transport
container and accessories (while observing the per-
missible temperature range). Repack the equipment
only once it is completely dry.
2. Check the accuracy of the equipment before it is
used after a long period of storage or transportation.
3. Remove rechargeable and non-rechargeable batter-
ies from the tool or the laser receiver before storing
the units for long periods. The tool or laser re-
ceiver may suffer damage caused by leakage from
rechargeable or non-rechargeable batteries.

8.4 Transport
Use the Hilti toolbox or packaging of equivalent quality
for transporting or shipping your equipment.
CAUTION
Remove the batteries from the tool and receiver before
transport or shipping.
8.5 Calibration by the Hilti Calibration Service
We recommend that the tool is checked by the Hilti
Calibration Service at regular intervals in order to ver-
ify its reliability in accordance with standards and legal
requirements.
Use can be made of the Hilti Calibration Service at any
time, We recommend that the tool is calibrated at least
onceayear
Thecalibrationserviceprovidesconfirmationthatthe
tool is in conformance, on the day it is tested, with the
specifications given in the operating instructions.
In the event of deviation from the manufacturer's speci-
fication, the used tool will be readjusted. After checking
and adjustment, a calibration sticker applied to the tool
and a calibration certificate provide written verification
that the tool operates in accordance with the manufac-
turer’s specification.
Calibration certificates are always required by companies
certified according to ISO 900x.
The Hilti representative in your local region will be pleased
to provide further information.
8.6 Checking accuracy
NOTE
In order to ensure compliance with the technical speci-
fications, the tool should be checked regularly (at least
before each major / relevant job).
NOTE
After falling and suffering an impact it can be presumed
that the tool will continue to operate faultlessly, with
the accuracy it achieved prior to the impact, when the
following conditions are met:
The height of the fall did not exceed the height given in
the technical data.
The tool suffered no obvious mechanical damage from
the impact (e.g. breakage of the pentaprism).
The tool projects a rotating laser beam when in operation.
The tool operated faultlessly before the impact.
8.6.1 Checking the main and transverse horizontal
axes 
1. Set up the tripod approx. 20 m from a wall and level
the tripod head with a spirit level.
2. Mount the tool on the tripod and use the aiming
notch to aim the tool at the wall.
3. Use the laser receiver to catch the laser beam and
mark a point (point 1) on the wall.
4. Pivot the tool clockwise through 90° about its own
axis. In doing so, ensure that the height of the tool
does not change.
5. Use the laser receiver to catch the laser beam and
mark a second point (point 2) on the wall.
6. Repeat steps 4 and 5 twice and mark points 3 and
4 on the wall with the aid of the laser receiver.
When this procedure is carried out carefully, the
vertical distance between the two marked points 1
and 3 (main axis) or, respectively, points 2 and 4
(transverse axis) should be less than 2 mm (at 20 m).
If the deviation is greater than this, the tool should
be returned to a Hilti Service Center for calibration.
