IMPORTANT SAFETY INSTRUCTIONS
CAUTION! WARNING! DANGER! Do not use the product before you have studied the
safety instructions and the user manual. Laser Classification
Laser Beam outlet aperture WARNING: It is a Class 2 laser product in
accordance with EN60825-1:2014 .
LASER 2
ENGLISH
WARNING: Avoid direct eye exposure. The laser beam can cause severe eye damage
and/or blindness. Do not stare into the laser beam or direct it towards other
people unnecessarily. Caution! The laser emitting product may be behind you in
some applications. Be careful when facing the product. WARNING: Do not operate
the laser around children or allow children to operate the laser. The
reflective surface could reflect the beam back at the operator or other
persons. WARNING: Use of controls, adjustments, or the performance of
procedures other than those specified in the manual may result in hazardous
radiation exposure. When the laser is brought into a warm environment from
very cold conditions, or vice versa, allow it to come to the surrounding
temperature before use. Always store the cross laser indoors, avoid
substantial knocks, continuous vibration or extreme temperatures. Always keep
the tool away from dust, liquids and high humidity. These may damage internal
components or affect accuracy. If laser radiation hits your eye, you must
close your eyes and immediately turn your head away from the beam. Do not
position the laser beam so that it unintentionally blinds you or others. 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. If you use
laser goggles to enhance the visibility of the laser beam, please notice that
they will not protect your eyes against laser radiation. Do not remove or
deface warning labels on the laser level. Do not disassemble the laser level,
laser radiation can cause serious eye injury. When not in use, turn off the
power, engage the pendulum lock and place the laser in its 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. Do not use aggressive
cleaning agents or solutions. Use only a clean, soft cloth for cleaning. Avoid
heavy impact to or dropping of the laser. The accuracy of the laser should be
checked before use if it has been dropped or subjected to other mechanical
stresses. Any repair required on this laser product should be performed only
by authorised service personnel. Do not operate the product in explosion
hazardous areas or in aggressive environments. If the laser level is not in
use for a long period of time, remove the batteries from the battery
compartment. This will prevent batteries from leaking and corrosion damage.
Flat batteries must not be disposed of with household waste. Care for the
environment and take them to the collection points provided in accordance with
national or local regulations. The laser must not be disposed with household
waste. Dispose of the product appropriately in accordance with the national
regulations in force in your country. Adhere to the national and country
specific regulations. Please contact your local authority or your dealer for
how to dispose of batteries properly.

MAINTENANCE
Wipe the aperture lens and the body of the cross laser with a clean soft
cloth. Do not use solvents.
Although the cross laser 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 cross laser is exposed to water, dry the laser level before returning
it to the carrying case to prevent corrosion damage.

PLUMB FUNCTION
With the plumb function, a point on the floor and on the ceiling can be
projected. Use the plumb function e.g. to transfer reference point for light
installation, vents, transfer of heights.
DETECTOR
For outdoor work under direct sunlight, or bright conditions and for extended
indoor ranges of up to 50 meters / 164 feet, use the Milwaukee detector.
A detector is not included and must be purchased separately.
For information on how to operate the detector, please refer to the operating
instructions for the detector.

ACCURACY CHECK
This cross laser left the factory fully calibrated. Milwaukee recommends the
user to check the accuracy of the laser periodically, especially if the unit
falls or is mishandled.
If the maximum deviation of the laser is exceeded in one of the accuracy
checks,please contact one of our Milwaukee service agents (see our list of
guarantee/service addresses).
1. Checking the height accuracy of the horizontal beam. 2. Checking the
leveling accuracy of the horizontal beam. 3. Checking the leveling accuracy of
the vertical beam. 4. Checking the plumb accuracy.
Before checking the laser accuracy, after mounting the laser on the tripod,
check the leveling of the tripod.
5. Turn the laser 180° towards wall B and mark the center of the cross beams
as b1 on the wall.

1 CHECKING THE HEIGHT ACCURACY OF THE HORIZONTAL BEAM (UP AND DOWN DEVIATION)
1. Set up the laser on a tripod or on a flat surface between two walls A and
B, approximately 5 meters apart.
2. Position the laser level approximately 0.5 meter from wall A. 3. Switch ON
the self-leveling mode 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.

2 CHECKING THE LEVEL ACCURACY OF THE HORIZONTAL BEAM (SIDE TO SIDE INCLINATION)
For this check, a free surface of approx. 5 x 5 meters is required.
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 2.5 meters from the center of the
room.
3. Switch ON the self-leveling mode and press the button to project the
horizontal line towards wall A and B.
4. Mark the center of the laser line point a1 on wall A and point b1 on wall
B.
5. Move the laser level approximately 5 meters away and turn the laser 180°
towards wall A and B.
6. Mark the center of the laser line point a2 on wall A and point b2 on wall
B.

3 CHECKING THE LEVEL ACCURACY OF THE VERTICAL BEAM
1. Hang an approximately 4 m 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.

4 CHECKING PLUMB ACCURACY
This procedure requires a room of with approx. 5m distance between floor and
ceiling.
1. Set up the cross laser on a tripod.
2. Switch ON the self-leveling mode and press the push button to switch to
the plump function.
3. Mark the upper plumb dot on the ceiling as point a1 (see the
illustration).
4. Mark the lower plumb dot on the floor as point b.

3. Set up the cross laser on a tripod or on a flat surface in front of the
wall at a distance of approximately 2 m.
4. Switch ON the self-leveling mode, and press the button to project the
vertical beam towards the plumb line.
5. Turn the cross laser so that 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.
7. The distance between a1 and a2, should be no more than 1 mm.
ENGLISH
a2 a1 P
5. Rotate the laser level 180°, position it so that the center of the plumb
dot is on the point b, which has already been marked, and allow it to level.
6. Mark the center of the upper plumb dot on the ceiling as point a2.
7. The distance between points a1 and a2 marked on the ceiling is an
indication of the actual deviation of the laser level from the ideal plumb
line. If the measuring distance is 5m, the maximum permissible deviation is:
5m x (+/- 0.6mm/m) x 2 = +/ – 6mm.
8. The distance between a1 and a2, should not be more than 6 mm.
