2.1 Use of the product as directed
The PML 42 is a self-leveling line laser which allows leveling and alignmentworktobecarriedoutquicklyand
accurately by a single person. The tool projects two laser lines (horizontal and vertical) and a line intersection point.
The lines and line intersection point have a range of approx. 10m. Range depends on the brightness of ambient light.
The tool is designed for mainly indoor use and is no substitute for a rotatinglaser.
When used for outdoor applications, care must be taken to ensure that the general conditions are similar to those
encountered indoors. Possible applications are:
Leveling power outlets, cable trays, radiators and in other items in installation work.
Leveling suspended ceilings.
Leveling and aligning doors and windows.
Transferring heights.
Vertical alignment of pipes.
Observe the information printed in the operating instructions concerning operation, care and maintenance.
Modification of the tool is not permissible.
To avoid the risk of injury, use only genuine Hilti accessories and insert tools.
The tool and its ancillary equipment may present hazards when used incorrectly by untrained personnel or when used
not as directed.
2.2 Features
The PML 42 levels itself automatically within a range of approx. 5°.
Self-leveling takes only approx. 3 seconds.
When the self-leveling range is exceeded, the laser beams blink to warn the user.
The PML 42 is characterized by its ease of operation and use, its rugged plastic casing and ease of transport due to
its compact dimensions and light weight.
The tool can be used together with the PMA 31 laser receiver.
In the normal operating mode, the tool switches itself off after 15 minutes. Sustained operating mode can be activated
by pressing and holding the on/off button for four seconds.

5 Safety instructions
In addition to the information relevant to safety given
in each of the sections of these operating instructions,
the following points must be strictly observed at all
times.
5.1 General safety rules
a) Check the accuracy of the tool before using it to
take measurements.
b) The tool and its ancillary equipment may present
hazards when used incorrectly by untrained per-
sonnel or when used not as directed.
c) To avoid the risk of injury, use only genuine Hilti
accessories and additional equipment.
d) Modification of the tool is not permissible.
e) Observe the information printed in the operat-
ing instructions concerning operation, care and
maintenance.
f) Do not render safety devices ineffective and do
not remove information and warning notices.
g) Keep laser tools out of reach of children.
h) Take the influences of the surrounding area into
account. Do not expose the tool to rain or snow
and do not use it in damp or wet conditions. Do
notusethetoolwherethereisariskoffireor
explosion.
i) Check the condition of the tool before use. If the
tool is found to be damaged, have it repaired at a
Hilti service center.
j) The user must check the accuracy of the tool
after it has been dropped or subjected to other
mechanical stresses.
k) When the tool is brought into a warm environment
from very cold conditions, or vice-versa, allow it
to become acclimatized before use.
l) If mounting on an adapter, check that the tool is
screwed on securely.
m) Keep the laser exit aperture clean to avoid meas-
urement errors.
n) 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.
o) Although the tool is protected to prevent entry
of dampness, it should be wiped dry each time
before being put away after use.
p) Check the accuracy of the measurements several
times during use of the tool.
5.2 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) Measurements taken through panes of glass or other
objects may be inaccurate.
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.
en

Printed: 08.07.2013 | Doc-Nr: PUB / 5070087 / 000 / 01

f) If several laser tools are used in the same working
area, care must be taken to avoid confusing the
beams.
g) Magnetic fields may affect the accuracy of the tool. It
must thus be kept away from magnetic objects. The
tool is not affected by the Hilti universal adapter.
h) When working with the receiver, it must be held
exactly at right angles to the laser beam.
i) Do not use the tool in the proximity of medical instru-
ments.
5.3 Electromagnetic compatibility
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
devices (e.g. aircraft navigation equipment).
5.4 Laser classification for laser class 2 / class II
appliances
Depending on the version purchased, the tool complies
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
unintentionally for a brief moment. This eyelid closure
reflex, however, may be negatively affected by medicines,
alcohol 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.
5.5 Electrical
a) Insulate or remove the batteries before shipping the
tool.
b) To avoid pollution of the environment, the tool
must be disposed of in accordance with the cur-
rently applicable national regulations. Consult the
manufacturer if you are unsure of how to proceed.
c) Keep the batteries out of reach of children.
d) Do not allow the batteries to overheat and do not
expose them to fire. The batteries may explode or
release toxic substances.
e) Do not charge the batteries.
f) Do not solder the batteries into the tool.
g) Do not discharge the batteries by short circuiting
as this may cause them to overheat and present
a risk of personal injury (burns).
h) Do not attempt to open the batteries and do not
subject them to excessive mechanical stress.
i) Do not use damaged batteries.
j) Do not mix old and new batteries. Do not mix
batteries of different makes or types.
5.6 Liquids
Liquid may leak from the batteries if they are used incor-
rectly. Avoid contact. If contact accidentally occurs,
rinse 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 leaking from the
battery may cause irritation or burns.

2.1 Anvendelsesformål
PML 42 er en selvnivellerende linjelaser, med hvilken en enkelt person er i stand til hurtigt og præcist at udføre
nivellerings- og positioneringsopgaver. Instrumentet har to linjer (vandret og lodret) og et linjeskæringspunkt. Linjerne
og skæringspunktet har en rækkevidde på ca. 10 m. Rækkevidden afhænger af lysstyrken i omgivelserne.
Instrumentet er fortrinsvis beregnet til anvendelse indendørs og er ikke en erstatning for en rotationslaser.
Udendørs brug er kun tilladt, hvis betingelserne er de samme som ved indendørs brug. Mulige anvendelser er:
Nivellering af stikdåser, kabelkanaler, radiatorer og installationer.
Nivellering af sænkede lofter.
Nivellering og positionering af døre og vinduer.
Overføring af højder.
Lodret positionering af rør.

5 Sikkerhedsanvisninger
Ud over de sikkerhedstekniske forskrifter i de enkelte
afsnit i denne brugsanvisning skal følgende retnings-
linjer altid overholdes.
5.1 Generelle sikkerhedsforanstaltninger
a) Kontrollér instrumentets nøjagtighed, før du fore-
tager målinger eller tager instrumentet i brug.
b) Der kan opstå farlige situationer ved anvendelse
af instrumentet og det tilhørende udstyr, hvis det
anvendes af personer, der ikke er blevet undervist
i dets brug, eller hvis det ikke anvendes korrekt i
henhold til forskrifterne i denne brugsanvisning.
c) Brug kun originalt Hilti-tilbehør og ekstraudstyr
for at undgå ulykker.
d) Det er ikke tilladt at modificere eller tilføje ekstra
dele til instrumentet.
e) Overhold forskrifterne i denne brugsanvisning
med hensyn til drift, rengøring og vedligeholdelse.
f) Undlad at deaktivere sikkerhedsanordninger og
fjerne advarselsskilte af nogen art.
g) Opbevar laseren utilgængeligt for børn.
h) Tag hensyn til påvirkning fra omgivelserne. Ud-
sæt ikke instrumentet for nedbør, brug ikke in-
strumentet i fugtige eller våde omgivelser. Brug
ikke fjernbetjeningen, hvis der er risiko for brand
eller eksplosion.
i) Kontrollér fjernbetjeningen før brug. Hvis fjern-
betjeningen er beskadiget, skal den sendes til
reparation hos Hilti.
j) Hvis instrumentet har været tabt eller udsat for
anden mekanisk påvirkning, skal dets nøjagtighed
testes.
k) Hvis instrumentet flyttes fra en meget lav tempe-
ratur ind i varmere omgivelser, eller omvendt, skal
det have tid til at akklimatisere, inden det tages i
brug.
l) Ved brug af adaptere/holdere skal det kontrolle-
res, at instrumentet er skruet ordentligt på.
m) For at undgå unøjagtige målinger skal laserstrå-
levinduerne altid holdes rene.
n) Selv om fjernbetjeningen er konstrueret til den
krævende anvendelse på en byggeplads, skal den
behandles forsigtigt som ethvert andet optisk og
elektrisk instrument (kikkert, briller, kamera).
o) Selvom instrumentet er modstandsdygtigt over
for fugt, bør det tørres af, så det er tørt, inden det
lægges i transportbeholderen.
p) Kontrollér nøjagtigheden flere gange under brug.
5.2 Formålstjenlig indretning af arbejdspladserne
a) Sørg for at sikre det sted, hvor instrumentet be-
nyttes. Sørg ved opstilling af instrumentet for, at
strålen ikke er rettet mod andre personer eller
mod dig selv.
b) Undgå at stå i akavede stillinger, når du arbejder
på en stige. Sørg for at have et sikkert fodfæste,
og hold balancen.
c) Målinger taget gennem glasplader eller andre objek-
ter kan være unøjagtige.
d) Sørg for, at instrumentet er opstillet med god
støtte og på et jævnt, stabilt underlag (vibrations-
frit).
e) Anvend kun instrumentet inden for de definerede
driftsgrænser.
f) Hvis der anvendes flere laserinstrumenter i ar-
bejdsområdet, skal du sikre dig, at du ikke kan
tage fejl af strålerne fra dit instrument og andre
instrumenter.
g) Magneter kan påvirke nøjagtigheden, derfor må der
ikke befinde sig magneter i nærheden. I forbindelse
med Hilti universaladapter sker der ingen påvirkning.
h) Ved arbejdet med modtageren skal denne holdes
absolut lodret i forhold til strålen.
i) Instrumentet må ikke anvendes i nærheden af medi-
cinske apparater.
5.3 Elektromagnetisk kompatibilitet
Selv om fjernbetjeningen opfylder de strenge krav i gæl-
dende direktiver, kan Hilti ikke udelukke muligheden for,
at fjernbetjeningen forstyrres af stærk stråling, hvilket
kan medføre en fejl. Hvis det er tilfældet eller i tilfælde
af usikkerhed, skal der foretages kontrolmålinger. Hilti
kan ligeledes ikke udelukke, at andre instrumenter (f.eks.
navigationsudstyr i fly) forstyrres.
5.4 Laserklassifikation for instrumenter i
laserklasse 2/class II
Alt efter den solgte version opfylder instrumentet kravene
i laserklasse 2 iht. IEC60825-1:2007 / EN60825-1:2007
og klasse II iht. CFR 21 § 1040 (FDA). Disse instrumen-
ter kan betjenes uden yderligere beskyttelsesforanstalt-
ninger. Øjenlågets lukkerefleks beskytter øjet, hvis man
kommer til at kigge kortvarigt ind i laserstrålen. Medicin,
da
13
Printed: 08.07.2013 | Doc-Nr: PUB / 5070087 / 000 / 01

alkohol eller narkotika kan dog forringe øjets lukkerefleks.
Dog bør man, ligesom med solen, undgå at kigge direkte
ind i lyskilden. Undlad at pege på andre personer med
laserstrålen.
5.5 Elektrisk
a) Isolér eller fjern batterierne i forbindelse med forsen-
delse.
b) Af miljøhensyn skal instrumentet bortskaffes i
overensstemmelse med gældende national lov-
givning. Er du i tvivl, så spørg producenten.
c) Batterierne skal opbevares utilgængeligt for børn.
d) Batterierne må ikke overophedes eller brændes.
Batterierne kan eksplodere eller afgive giftige stoffer.
e) Batterierne må ikke oplades.
f) Batterierne må ikke loddes sammen i fjernbetje-
ningen.
g) Batterier må ikke aflades ved kortslutning, da de
derved kan overophedes og medføre brandfare.
h) Batterierne må ikke åbnes eller udsættes for kraf-
tige mekaniske belastninger.
i) Brug aldrig beskadigede batterier.
j) Brug ikke nye og gamle batterier sammen. Undgå
at bruge batterier af forskellige mærker eller med
forskellige typebetegnelser.
5.6 Væsker
Hvis batteriet anvendes forkert, kan der løbe væske ud
af batteriet. Undgå at komme i kontakt med denne
væske. Hvis det alligevel skulle ske, skylles med vand.
Hvis du får væske i øjnene, skal du skylle med rigeligt
vand, og søge læge. Batterivæske kan give hudirritation
eller forbrændinger.
