SAFETY INSTRUCTIONS
WARNING
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
protect your eyes against laser radiation.

• 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.

BATTERY INSTALLATION & SAFETY
NOTE
If the Pendulum lock mechanism is not
engaged before Transportation, internal
mechanical damage can occur.
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.

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 from children.

OPERATING INSTRUCTIONS
Working in Automatic mode (self-leveling):
In automatic mode the laser level will level itself in the
range of ± 3° and will project horizontally or vertically 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.Push the locking switch #1 forward to the ON position.
The laser level will generate the crossed horizontal and
vertical lines and the green LED will light up.
3.Choose the beams that you want to work with by
pushing the V/H operation push button
4.If the initial slope of the laser is beyond ± 3° the laser
lines will ash. In this case reposition the laser on a
more leveled surface.
5.Before moving the laser level switch the locking switch
#1 backward to the OFF position, this will lock the
pendulum and protect your laser.

11
OPERATING INSTRUCTIONS
Working in Manual mode:
In Manual mode the 862’s self-leveling mechanism is
disabled and the laser lines can be set at any slope required.
1.Long press on the V/H operation push button (#3) will
activate the Manual mode. The laser will project blinking
cross lines and the red LED will light up.
2.Choose the beams that you want to work with by
pushing shortly the V/H operation push button
3.Tilt the laser to the desirable slope.
4.To turn the manual mode OFF, press again the V/H
operation push button for 3 sec.
5.While in Manual mode turning the locking switch #1
from OFF to ON position 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.

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 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.

13
MAINTENANCE
This laser level left the factory fully calibrated. Kapro
recommend 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 leveling 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 A and 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).

5) Turn the laser 180° towards wall B, and mark on the wall
the center of the cross lines as b1 (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 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
2 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 meters 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 in the middle of the horizontal line
(see gure 6).

5) The distance between a1 and a2, should not be more
than 1 mm otherwise to send the laser level to a qualied
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 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.
