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.
OVERVIEW Plumb spot up (only L4 CLLP) Beam selector LED indicator horizontal Vertical laser beam window vertical cross line Horizontal laser beam window Mode button Short press: choose between beams: - horizontal - vertical + plumb function - cross lines + plumb function Long press: low power mode Rotation dial Off / locked On / manual mode LED indicator - Fuel gauge - Charging status On / self leveling mode Battery Magnetic mount Riser (only L4 CLLP) USB port LED indicator - Fuel gauge - Chargin
ACCESSORY REPLACE BATTERIES Accessory - Not included in standard equipment, available as an accessory. Only use Milwaukee Type L4B3 rechargeable batteries.
FUEL GAUGE CHARGE After switch on or switch off the laser the fuel gauge will display the battery life for 3 seconds It is possible to work with the laser during charge.
MAGNETIC WALL MOUNT Use the magnetic wall mount to fix the laser to a wall or metallic structures or similar. Turn the laser 360° with fine adjustment.
RISER TRACK CLIP Use the riser to come over the floor track Use the track clip to clamp the laser to ceiling channels, racks....
WORKING IN SELF-LEVELING MODE In self-leveling mode the cross laser will level itself in a ± 4° range and can project a horizontal beam, a vertical beam or both beams simultaneously + plumb dot up and down (plumb dot only L4 CLLP). 1 4 1/4" male thread Place the cross laser on a solid flat vibration free surface or on a tripod. Choose the beams that you want to work with by pushing the MODE button. 2 Turn the rotation dial to: . 3 C The cross laser will generate 2 laser beams.
WORKING IN MANUAL MODE In manual mode the cross lasers self-leveling mechanism is disabled and the laser lines can be set at any slope required. 1 4 Place the cross laser on a solid flat vibration free surface or on a tripod. Choose the beams that you want to work with by pushing the MODE button. 2 Turn the rotation dial to: 3 5 Same as in the self-leveling mode, the cross laser will generate 2 laser beams, but the laser beams are interrupted every 8 seconds. 8 sec. 8 sec.
PLUMB FUNCTION DETECTOR 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. 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.
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.
2 1. 2. 3. 4. 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. Set up the laser on a tripod or on a solid surface between two walls A and B, approximately 5 meters apart. Position the laser level approximately 2.5 meters from the center of the room. Switch ON the self-leveling mode and press the button to project the horizontal line towards wall A and B.
3 CHECKING THE LEVEL ACCURACY OF THE VERTICAL BEAM a1 a2 a1 P b a1 P ENGLISH 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. 1.
