SAFETY INSTRUCTIONS
WARNING
This product emits radiation classified 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,since it will
increase the level of eye injury.
WARNING: This product contains lead in soldered joints
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.

Charge the Li- Ion battery or use new AA Alkaline batteries if
the beam/ battery indicator (b) starts to ash instead of emitting
a steady light.
NOTE: Connecting the charger with the charging adaptor to
the power (without the battery) will show a steady green LED
indicator with a small blinking dot. During the charging the LED
indicator (on the charging adaptor)
will be red and then green,
once fully charged.

OPERATING INSTRUCTIONS
Working in Automatic mode (self-leveling):
In automatic mode the laser level will level itself in a ± 2.5°
range and will project 1 horizontal 360° or/and 2 vertical
360° green beams.
1. Remove the laser level from the case and place it on a
solid, at, vibration free surface or on a tripod.
2. Push the locking switch #1 to the ON position. The laser
level will project a 360° horizontal beam. The beam
indicator (b) will turn on.
3. Press the beam selector button (a) - it will turn on a 360°
vertical side beam instead of the horizontal beam.
4. An additional click on the beam selector button will turn
on a 360° vertical front beam in addition to the side vertical
beam.
5. One more click on the beam selector button (a) will switch
on the horizontal beam in addition to the vertical beams.
6. An additional click on the beam selector button (a) will
switch off the two vertical beams.
7. If the initial inclination of the laser level is beyond ± 2.5°
and the automatic mode is activated, the laser beams will
ash. In this case reposition the laser level on a more level
surface.
8. Before moving the laser level turn the locking switch
#1 to the OFF position, this will lock the pendulum and
protect your laser level.

11
Working in Manual mode:
In Manual mode the 883G self-leveling mechanism is disabled
and the laser beams can be set at any slope required.
1. Verify that the locking switch #1 is on the OFF position.
2. Press and hold the Manual mode button (a) for 3 seconds, to activate
the manual mode. The laser level will project a 360° horizontal
beam that will ash every 3 sec. to let you know that the beam
is not leveled. The beam indicator (b) will turn on.
3. To mark a slope, tilt the laser to the desired angle.
4. To choose another beam, briey press the beam selector
button (a) - it will turn on a 360° vertical side beam instead of
the horizontal beam.
5. An additional click on the beam selector button (a) will add a
360° forward vertical ashing beam.
6. One more click on the beam selector button (a) will switch on
the horizontal beam in addition to the vertical beams.
7. Next click on the beam selector button (a) will switch OFF all
the beams and the beam indicator (b) will turn off.
8. While in Manual mode, turning the locking switch #1 from OFF
to ON will turn off the Manual mode. The automatic self –
leveling mode 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 up to 70 meters, 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 the laser beams.
1. The pulse mode can be activated both in Automatic and
in Manual mode.
2. Turn on the laser level (to the required mode).
3. Press the Pulse mode button (c) to activate it. The Pulse
mode indicator (d) will turn on. Visually, the intensity
of the beam will be a bit reduced.
4. Turn on the detector and search for laser beam.
5. You can choose a different beam, by pressing on the
beam selector button (a), while you are in Pulse Mode.
6. To switch the Pulse Mode off, press the Pulse mode
button (c) and the Pulse mode indicator (d) will turn off.

13
MAINTENANCE
To maintain the accuracy of your project, check the accuracy
of your laser level according to the eld calibration tests
procedures.
• Change the battery 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, don't 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 battery if the laser level is unused for a long
period of time to prevent corrosion damage.

FIELD CALIBRATION TEST
This laser level left the factory fully calibrated. Kapro
recommends the user check the accuracy of the laser
periodically, especially if the unit falls or is mishandled.
1. Check the height accuracy of the cross created by the lateral
(#5) and the horizontal lines.
2. Check the height accuracy of the cross created by the
longitudinal (#4) and the horizontal lines.
3. Check the accuracy of the forward vertical beam.
4. Check the accuracy of the side vertical beam.
5. Check the perpendicularity between the 2 vertical beams.
1.Checking the Height Accuracy of the cross created by
the lateral (#5) Horizontal lines.
(Up and down deviation)
1) Set up the laser on a table or on the oor between 3 walls
A, B and C. The distance between A and Bshould be
approximately 5 meters.
2) Position the laser level approximately 0.5 meters from wall A
and 2 meters from wall C.
3) Unlock the pendulum and press the Beam Selector (a),
twice to project all 3 lasers beams.
4) Direct the cross lines of the horizontal beam and the side
vertical beam (# 5) towards wall A.
5) Mark on wall Athe center of the cross beams as a1,
and on wall Cmark the center of the cross beam as c1
(see gure # 1).

15
6) Turn the laser 180° towards wall B. Reposition the laser and
verify that the 2 vertical lines pass through a1 and c1.
7) Mark on wall Bthe center of the cross beams as b1
(see gure # 2).

2. Checking the Height Accuracy of the cross created by
the longitudinal (#4) and horizontal lines.
(Up and down deviation)
1) Set up the laser on a table or on the oor between 3 walls
A, B and C. The distance between Aand Bshould be
approximately 5 meters.
2) Position the laser level approximately 0.5 meters from wall A
and 2 meters from wall C.
3) Unlock the pendulum and press the Beam Selector (a) twice,
to project all 3 lasers beams.
4) Direct the cross lines of the horizontal beam and the forward
vertical beam (#4) towards wall A.
5) Repeat the previous marking procedures from paragraph 5 - 15
3. Checking the Accuracy of the forward Vertical beam (#4).
1) Hang an approximately 3 meter long 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 # 5).

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 forward beam (#4) towards the plumb line.
5) Turn the laser, so the vertical beam will merge with the
plumb line below the hanging point.
6) Mark point a2 on the wall, in the middle of the vertical beam
at the same height as a1. (see gure # 6).
