OPERATING INSTRUCTIONS
Working in Automatic mode (self-leveling):
In automatic mode the laser level, will level itself at a ±3° range
and can project 1 horizontal, 4 vertical lines, and 1 plumb dot.
These lines will create 1 cross line on the wall, and a second
cross line on the ceiling.
1. Remove the laser from the case and place it on a at, vibration
free surface or on a tripod.
2. Adjust the unit’s support legs (#6), or the tripod legs, until the
surface level (#4) is centered.
3. Turn the pendulum safety lock (#11) clockwise to the ON
position. The surface level at the center of the keypad (#4)
will light up and the forward cross beam and plumb dot will be projected.
4. To direct the beams to the desirable position turn the laser and
use the ne – adjustment knob (#5) for precise positioning.
5. Press the V button (#2) and the rear vertical beam will also be
projected.
6. An additional click on the V button (#2) will project the additional
2 side vertical beams creating an additional cross beam above
the laser.
7. One more click on the Vbutton (#2) will turn off all the vertical
beams at once.
8. Press the Hbutton (#1) to turn the horizontal beam on or off.
9. If the initial level of the laser is beyond ± 3°, the laser beams
will ash and a beeping alarm will be heard. In this case
reposition the laser on a more leveled surface.
10. Before moving the laser level, turn the pendulum safety
lock (#11) counterclockwise to the OFF position. This will lock
the pendulum and protect your laser.

12
Working in Manual mode:
In Manual mode the 875’s self-leveling mechanism is disabled and
the laser beams can be set at any slope required.
1. Long press on the Mbutton (#3) will activate the Manual
mode. The laser will project blinking forward cross beams, and
the red LED (#5) will light up.
2. Choose the beams that you want to work with by pressing the
Vor Hbuttons.
3. To mark the slope, tilt the laser to the desired slope.
4. To turn the manual mode OFF, press the Mbutton (#3) again.
5. If while in Manual mode you turn the pendulum safety lock (#11)
from OFF to ON. it will incapacitate the Manual mode and the
red LED (#5) near the M(#3) button. If the laser level is within
its self-leveling range, the automatic self-leveling feature will be
activated.

13
Working in Pulse mode with a detector:
For outdoor work under direct sunlight, or bright conditions and for
extended outdoor ranges up to 60m (200’) for 1 green horizontal
line and 50m (165’) for 4 red vertical lines, 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 detect them.
1. The Pulse mode can be activated in Automatic and Manual
modes.
2. To switch on the Pulse Mode press the Pbutton (#4), the
green LED (#6) near the P(#4) button 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 (#4) again,
the green LED (#6)near the P(#4) button will turn itself off.
5. The green and the red laser beams require different detectors
to work with.
