OPERATING INSTRUCTIONS
Working in Automatic mode (self-leveling):
In Automatic mode, the laser will level itself in a ± 3° range
and project horizontal, vertical or both lines 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 the crossed horizontal and
vertical lines and the green LED near the V/H button will
light up.
3. Choose the beams that you want to work with presing the
V/H beam button.
4. Use the adjustable metal legs (#2) to adjust the height of
the horizontal line.
5. If the initial slope of the laser is beyond ± 3° and the
automatic mode is activated the laser lines will ash and a
beeping alarm will sound. In this case reposition the
laser on a more leveled surface.
6. Before moving the laser level, turn the locking switch (#1)
to the OFF position, this will lock the pendulum and protect
your laser.

11
Working in Manual mode:
In Manual mode the 872G’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 modify the 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, bright conditions or
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 ash at
very high frequency (invisible to the human eye) allowing
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 P push button will light up.
3. When the Pulse mode is switched on, the visibility of the
laser lines are reduced a little bit.
4. To switch the Pulse mode off, press the Pbutton again,
the green LED near the Pbutton will turn off.

MAINTENANCE
To maintain the accuracy of your project, check the accuracy
of your laser level according to the eld calibration tests
procedures.
• Change the batteries when the laser beams begins 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.
Repairs
See the warranty section at the end of this manual.
• Do not take the 872G Prolaser apart or permit unqualied
persons to disassemble it.
• Repair the measuring tool through qualied technicians
using original spare parts.
• Unauthorized service may cause eye injury, irreparably
damage the laser level and void the warranty.

periodically, especially 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 at 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 the center of the cross beams on the wall as a1
(see gure # 1).

5) Turn the laser 180° towards wall Band mark the center
of the cross beams as b1 on the wall (see gure 2).
6) Move the laser level towards wall Band position it
approximately 0.5 meter from wall B.
7) Mark on wall Bthe center of the cross beams as b2
(see gure 3).

16
8) Turn the laser 180° towards wall A, and mark on the wall the
center of the cross lines as a2 (see gure 4).
9) Measure the distances:
Δa= |a2-a1|
Δb= |b1-b2|
10) The difference | Δa – Δb| should be no more than 2 mm,
otherwise send the laser level to a qualied technician
for repair.
Checking the Level Accuracy of the Horizontal beam.
(Side to side inclination)
1) Set up the laser on a tripod or on a at surface at a distance
of approximately 1.5 meters from a 5 meter/16 feet long wall.
2) Unlock the pendulum and press the button to project the
horizontal and the vertical cross beams towards the wall.

17
3) Mark point a1 on the wall, in the middle of the horizontal line
at the left edge of the horizontal beam (see gure 5).
4) Turn the laser level counterclockwise until the right edge of
the horizontal line reaches near a1, mark a point a2 on the
wall in the middle of the horizontal beam (see gure 6).

18
5) The distance between a1 and a2, should be no more than
1 mm, otherwise, send the laser level to a qualied technician
for repair.
Checking the Accuracy of the Vertical beam.
1) Hang an approximately 4 meter/13 feet 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 gure 7).
3) Set up the laser on a tripod or on a at surface in front of the
wall at a distance of approximately 2 meters/6.5 feet.
4) Unlock the pendulum, and press the button to project the
vertical beam toward the plumb line.
5) Turn the laser so that the vertical beam will merge with the
plumb line below the hanging point.

19
6) Mark point a2 on the wall, in the middle of the vertical beam
at the same height as a1. (see gure 8).
7) The distance between a1 and a2, should be no more than
1mm, otherwise send the laser level to a qualied technician
for repair.
