LASER LEVEL - USER MANUAL 05
WARNING
This product is emitting radiation that is classied as
class II according to EN 60825-1
The 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 parts 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.

■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 atmospheres such as
flammable liquids, gases or dust. Sparks from the tool can
cause ignition
■When not in use, turn off the power, engage the pendulum
lock and place the laser in the 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 can occur.

1. Press on the latch and open the battery cover.
2. Insert 3 new AA batteries of the same brand, according to
the polarity diagram on the inside of the lid of the battery
compartment.
3. Reclose the battery cover.
NOTE: If the laser level will not be used for a long
period, remove the batteries from the battery
compartment. This will prevent batteries from leaking
and corrosion damage.

Working in Automatic mode (self-leveling):
In automatic mode the laser level will level itself at a ±3° range
and will project horizontal or vertical beams or both beams
simultaneously.
1. Remove the laser from the case and place it on a solid flat,
vibration free surface or on a tripod.
2. Slide the locking switch #1 to the ON position – the laser
level will generate the crossed horizontal and vertical beams
and the green LED near the V/H button will light up.
3. Choose the beams that you want to work with by pushing
the Beam button V/H
4. If the initial slope of the laser is beyond ±3° and the
automatic mode is activated the laser lines will flash and a
beeping alarm will be heard. In this case reposition the laser
on a more leveled surface.
5. Before moving the laser level slide the locking switch #1 to
the OFF position, this will lock the pendulum and protect
your laser.

LASER LEVEL - USER MANUAL 11
Working in Manual mode:
In Manual mode the 870’s self-leveling mechanism is disabled
and the laser lines can be set at any angle required.
1. Press the Manual mode button . The laser will project
the cross lines and the red LED near the button will light
up. The green LED of the laser beams near V/H button will
light up as well.
2. Choose the beams that you want to work with by pushing
the Beam Selector button V/H
3. To mark a slope, tilt the laser to adjust the right angle and
the height.
4. To turn the manual mode off, press again the Manual mode
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 button. The automatic self-leveling will be
activated if the laser level is within the ±3° self–leveling range.
Working in Pulse mode with a detector:
For outdoor work under direct sunlight, or bright conditions
and for extended indoor ranges up to 60 meters, use the
pulse mode with a Detector.
When the pulse mode is activated the laser lines will flash at
very high frequency (Invisible to the human eye) this will allow
the detector to detect the laser lines.
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 near the Ppush button will light up.

LASER LEVEL - USER MANUAL 13
To maintain the accuracy of your project, check the accuracy
of your laser level according to the field calibration tests
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 a 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
damages
■Remove the batteries if the laser level is unused for a long
period of time to prevent corrosion damages

This laser level left the factory fully calibrated. OX recommend
that the user will check the accuracy of the laser periodically,
or if the unit falls or is mishandled.
To do so first check the height accuracy of the horizontal line,
then check the levelling accuracy of the horizontal line, and
finally check the leveling accuracy of the vertical line.
Checking the Height Accuracy of the Horizontal Line.
(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 lines towards wall A.
4) Mark on the wall the center of the cross lines as a1 (see
figure #1).

5) Turn the laser 180° towards wall B, and mark on the wall
the center of the cross lines as b1 (see figure #2).
6) Move the laser level towards wall Band position it
approximately 0.5 meter from wall B.
7) Mark on wall B the center of the cross lines as b2 (see
figure #3).

8) Turn the laser 180° towards wall A, and mark on the wall
the center of the cross lines as a2 (see figure #4).
9) Measure the distances:
Δa = |a2-a1|
Δb = |b1-b2|
10) The difference |Δa – Δb| should not be more than 2 mm,
otherwise to send the laser level to a qualified technician
for repairs.
Checking the Level Accuracy of Horizontal Line.
(Side to side inclination)
1) Set up the laser on a tripod or on a solid surface at a
distance of approximately 1.5 meters from a wall 5 meter
long.
2) Unlock the pendulum and press the button to project the
horizontal and the vertical cross lines towards the wall.

3) Mark point a1 on the wall, in the middle of the horizontal
line at the left edge of the horizontal line (see figure #5).
4) Turn the laser level counterclockwise until the right edge of
the horizontal line reach’s near a1, mark a point a2 on the
wall in the middle of the horizontal line (see figure #6).

5) The distance between a1 and a2, should not be more
than 1 mm otherwise to send the laser level to a qualified
technician for repairs.
Checking the Accuracy of the Vertical line.
1) Hang approximately 4 meter plumb line on a wall.
2) After the plumb line has settled, Mark point a1 on the wall
behind the plumb line near the plumb cone (see figure #7).
3) Set up the laser on a tripod or on a solid surface in front of
the wall at a distance of approximately 2 meters.
4) Unlock the pendulum, and press the button to project the
vertical line toward the plumb line.
5) Turn the laser so that the vertical line will merge with the
plumb line below the hanging point.

6) Mark point a2 on the wall, in the middle of the vertical line
at the same height of a1 (see figure #8).
7) The distance between a1 and a2, should not be more
than 1mm, otherwise to send the laser level to a qualified
technician for repairs.
