• Insert the batteries observing the correct polarity
• Use alkaline batteries or rechargeable batteries only.
• Remove the batteries if the instrument is not to be used for a long period of time (to prevent corrosion).

Charging the rechargeable battery pack / first-time use

• In case that your Lino ML is equipped with a rechargeable battery pack you can recharge the battery pack with the supplied Lino ML charger (Art Nr. 784967) by connecting the charger to the jack on the battery door.
• The battery must be charged prior to first use because it is delivered with as low an energy content as possible.
• A full charging cycle takes 8 hours and the charging will automaticly stop after a full cycle. Each time the charger is connected to the unit a charging cycle will be initiated. See also battery status indications on the interface in section "Interface".
• The permissible temperature range for charging is between 0°C and +40°C/+32°F and +104°F. For optimal charging we recommend charging the batteries at a low ambient temperature of +10°C to +20°C/+50°F to +68°F if possible.
• It is normal for the battery to become warm during charging.

Using the Laser with a receiver
To be able to detect the laser lines over long distances (> 15 m) or in unfavourable lighting condi- tions, a laser receiver can be used. Laser lines can be detected by a receiver that is able to detect pulsed laser lines. The lines of the Lino ML are permanently pulsed and are compatible with the range of recom- mended Leica laser receivers.
See section "Working with receivers".

Applications

Manual fine adjustment of vertical lines
The Lino ML90 and ML180 lasers feature the possi- bility to manually turn the unit 360° around its center axis and the possibility to fine adjust the unit by ± 4° turning around the plumb axis. On the ML180 the fine adjustment can be set to its 0° position by pressing both mode keys and at the same time for more than 2 seconds.
By turning the adjustment knob the laser beams can be aligned manually.
Additionally to the manual fine adjustment possibility described above, the Lino ML180 has the possibility to automatically align itself to the position of the Leica XCR Catch remote/receiver. For a detailed description of all functions, please, refer to the section "Working with receivers".

Checking the accuracy of the horizontal line
Set up the instrument on an even and flat surface. Allow the instrument to level. Position the instrument approx. 5 m away from the wall. Direct the instrument at the wall and switch on the horizontal and front vertical Laser line and mark the intersection point of laser crosshairs on the wall. Swivel the instrument to the right and then to the left. Observe the vertical deviation of the horizontal line from the marking. If the difference does not exceed 3 mm, then the Leica Lino is within tolerance.

Checking the accuracy of the vertical line
Set up the instrument on an even and flat surface. Allow the instrument to level. As reference, use a plumb-bob and attach it as close as possible to an approx. 3 m high wall. Position the instrument at a distance of approx. 1.5 m from the wall at an elevation of approx. 1.5 m. Direct the instrument at the wall and switch on the laser. Activate one of the vertical laser lines. Rotate the instrument and align it with the bottom of the plumb line. Now read off the maximum deviation of the laser line from the top of the plumb line. If the difference does not exceed 2 mm, then the Leica Lino is within tolerance.
