SAFETY INSTRUCTIONS
WARNING
This product emits radiation that is classified
as class II according to EN 60825 -1
Laser radiation can cause serious eye injury
• Do not stare into the laser beam
• Do not position the laser beam so that it unintentionally
blinds you or others.
• Do not operate the laser level near children or let children
operate the laser level.
• Do not look into a laser beam using magnifying optical
devices such as binoculars or a telescope, as this will
increase the level of eye injury.
WARNING: This product contains lead in solder and
certain electrical components contain chemicals which
are known to the State of California to cause cancer,
birth defects or other reproductive harm.
(California Health & Safety Code Section 25249.6- Proposition 65)
NOTE
The green goggles are intended to enhance
the visibility of the laser beam. They will not
protect your eyes against laser radiation.

6
• Do not remove or deface warning labels on the laser level.
• Do not disassemble the laser level, laser radiation can
cause serious eye injury.
• Do not drop the laser.
• Do not use solvents to clean the laser.
• Do not use in temperatures below -10°C or above 45°C
(14°F / 113°F)
• Do not operate the laser in explosive surroundings such as
ammableliquids,gasesordust.Sparksfromtoolscan
cause ignition.
• When not in use, turn off the power, engage the pendulum
lock and place the laser in its carrying pouch.
• Make sure the pendulum lock mechanism is engaged
before transporting the laser.
NOTE
If the Pendulum lock mechanism is not
engaged before transportation, internal
mechanical damage may occur.

BATTERY INSTALLATION
1. Press down the latch and remove the battery cover.
2. Insert 3 new AA batteries of the same brand according to
the polarity diagram on the inside of the battery compartment.
3. Reclose the battery cover.
NOTE
If the laser level is not in use for a long period
of time, remove the batteries from the battery
compartment. This will prevent batteries from
leaking and corrosion damage.

8
WARNING: Batteries can deteriorate, leak, explode, causing
injuryorre.
1. Do not shorten the battery terminals.
2. Do not charge Alkaline batteries.
3. Do not mix old and new batteries.
4. Do not dispose of batteries into household waste.
5.Donotdisposeofbatteriesinre.
6. Defective or dead batteries must be disposed of, according
to local regulations.
7. Keep the batteries out of reach of children.

OPERATING INSTRUCTIONS
Working in Automatic mode (self-leveling):
In automatic mode the laser level will level itself in a ±3° range
and can project a horizontal beam, two vertical beams or all 3 beams
simultaneously.
1.Removethelaserfromthecaseandplaceitonasolidat 
vibration free surface or on a tripod.
2.Turn the locking switch #1 clockwise to the ON position.
The laser level will generate horizontal and vertical beams
forward and an additional orthogonal side vertical beam. The
green LED near the V/H button will light up.
3.The laser will generate upwards and forward cross beams
when all beams are activated.
4.Choose the beams that you want to work with by pushing the
V/H beam button
5.Use the adjustable metal legs #2 to adjust the height of the
horizontal beam.
6.If the initial level of the laser is beyond ± 3° and the automatic
 modeisactivatedthelaserbeamswillashandabeepingalarm
will be heard. In this case reposition the laser on a more level
surface.
7.Before moving the laser level, turn the locking switch #1 to
the OFF position, this will lock the pendulum and protect
your laser.

Working in Manual mode:
In Manual mode the 873G’s self-leveling mechanism is disabled and
thelaserlinescanbesetatanysloperequired.Thelaserbeamswill
ashevery3secondstoletyouknowthatyouareworkingoutside
the self-leveling range and the beams may not be leveled
1. Press the Manual push button mode . The laser will
project the cross lines and the red LED near the push
button will light up. The green LED of the laser beams near
V/H push button will light up.
2. Choose the beams that you want to work with by pushing
the Beam Selector push button V/H
3. To mark a slope, tilt the laser using the adjustable folding
legs to adjust the right angle and the height.
4. To turn the manual mode off, press again the Manual
push button .
5. While in Manual mode turning the locking switch #1 from
OFF to ON will turn off the Manual mode and the red LED
near the push button. The automatic self – leveling
will be activated if the laser level is within the self – leveling range.

12
Working in Pulse mode with a detector:
For outdoor work under direct sunlight, or bright conditions and
for extended indoor ranges of up to 60 meters/ 200 feet, use the
Pulse Mode with a Detector.
WhenthePulseModeisactivatedthelaserbeamswillashat
averyhighfrequency(invisibletothehumaneye)thiswillallow
the detector to locate the laser beams.
1. The Pulse Mode can be activated in Automatic and Manual modes.
2. To switch on the Pulse Mode press the Pbutton, the green
LED next to it will light up.
3. When the Pulse Mode is switched on, the visibility of the laser
beams are reduced a little bit.
4. To switch off the Pulse Mode press the Pbutton again and the
green LED near it will turn off.

MAINTENANCE
To assure the accuracy of your project, check the accuracy
ofyourlaserlevelaccordingtotheeldcalibrationtest
procedures.
• Change the batteries when the laser beams begin to dim.
• Wipe the aperture lens and the body of the laser level with a
clean soft cloth. Do not use solvents.
• Although the laser level is dust and dirt resistant to a certain
degree, do not store in dusty places as long term exposure
may damage internal moving parts.
• If the laser level is exposed to water, dry the laser level
before returning it to the carrying case to prevent corrosion
damage.
• Remove the batteries if the laser level is unused for a long
period of time to prevent corrosion damage.

FIELD CALIBRATION TESTS
This laser level left the factory fully calibrated. Kapro
recommend that the user will check the accuracy of the laser
periodically, or if the unit falls or is mishandled.
1. Check the height accuracy of the horizontal beam.
2. Check the leveling accuracy of the horizontal beam.
3. Check the leveling accuracy of the vertical beam.
4. Check the perpendicularity between the 2 vertical beams.
1. Checking the Height Accuracy of the Horizontal beam.
(Up and down deviation)
1) Set up the laser on a tripod or on a solid surface
between two walls Aand B, approximately 5 meters apart.
2) Position the laser level approximately 0.5 meter from wall A
3) Unlock the pendulum and press the button to project the
horizontal and the vertical cross beams towards wall A.
4) Mark on the wall the center of the cross beams as a1
