FEATURES

5
This product is emitting radiation that is 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, 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 red goggles are intended to enhance the
visibility of the laser beam. They will not pro-
tect your eyes against laser radiation.
SAFETY INSTRUCTIONS
WARNING

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 atmospheres such as
ammable 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 may occur.

WARNING: Batteries can deteriorate, leak or explode, and
can cause 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 batteries in re.
6. Defective or dead batteries must be disposed according to
local regulations.
7. Keep the batteries out of reach of children.
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.

OVERVIEW

10
Working in Automatic mode (self-leveling):
In automatic mode the laser level will level itself in the range
of ± 3° and will project a horizontal line, vertical line or both
lines simultaneously.
1. Remove the laser from its case and place it on a solid, at,
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 lines.
3. Choose the beams that you want to work with by pressing
the H/V button.
4. If the initial slope of the laser is beyond ± 3° and the
automatic mode is activated, the laser lines will ash.
In this case, reposition the laser on a leveled surface.
5. Before moving the laser level, switch the laser to OFF.
This will lock the pendulum and protect your laser.
OPERATING INSTRUCTIONS

11
Working in Manual mode:
In Manual mode, the 852’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 without
the self-leveling and the beams may not be leveled.
1. Press the Manual push button mode M. The laser will project
the cross lines.
2. Choose the beams that you want to work with by pushing
the Beam Selector push button H/V.
3. To mark a slope, tilt the laser using to reach the required angle.
4. To turn the manual mode off, press again the Manual
push button M.
5. While in Manual mode sliding the locking switch #1 from
OFF to ON will turn off the Manual mode. 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 light
conditions, and for extended indoor ranges up to 40 meters,
use the Pulse mode with a detector.
When the pulse mode is activated, the laser lines will ash at
a very high frequency (invisible to the human eye). This will
allow the detector to detect the laser lines. The pulse mode
can be activated in both Automatic and Manual modes.
1. To turn the Pulse mode on , press the Pbutton.
2. When activated, a slight reduction in laser line brightness
will occur.
3. To turn the Pulse mode off, press the Pbutton again.
4. Laser lines brightness will return to previous brightness.

13
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 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 not used for a long
period of time to prevent corrosion damages.

This laser level left the factory fully calibrated.
Kapro recommends that the user will check the accuracy of the
laser periodically, or if the unit falls or is mishandled.
To do so rst check the height accuracy of the horizontal line,
then check the levelling accuracy of the horizontal line, and
nally 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 gure # 1).

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 lines as b2
(see gure 3).

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 not be more than 3 mm,
otherwise to send the laser level to a qualied 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 gure 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

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 gure 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.
