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.
