Leica Lino L2 / L2G - Green Laser Tech Manual

Overview

Overview The Leica Lino L2/L2G is a self-levelling crossline laser. It is a reliable precision laser for any kind of tasks like levelling, transfering and setting out right angles. It supports you on job side with two crossing vertical and horizontal lines.

There are 2 different types available:

• L2 (red laser)
  
• L2G (green laser)
  
  On all images in this document only the red laser version is shown.

Instrument Set-up

Introduction
The safety instructions (see Safety Instructions) and the user manual should be read through carefully before the product is used for the first time.
The person responsible for the product must ensure that all users understand these directions and adhere to them.
The symbols used have the following meanings:

Indicates a potentially hazardous situation or an unintended use which, if not avoided, will result in death or serious injury.

Indicates a potentially hazardous situation or an unintended use which, if not avoided, may result in minor injury and/or appreciable material, financial and environmental damage.
Important paragraphs which must be adhered to in practice as they enable the product to be used in a technically correct and efficient manner.

Levelling lock
Levelling unlocked
In the unlocked position the instrument automatically levels itself within the specified inclination range. (See Technical data)

Levelling locked
Turn the levelling lock in order to transport or tilt the instrument beyond the self-levelling range. When locked, the pendulum is fixed and the selflevelling function is deactivated. In this case the laser blinks every 5sec.

Laser receiver
To be able to detect the laser lines over long distances or in unfavourable lighting conditions, a laser receiver can be used.
We recommend the Leica RGR200 laser receiver. The Lino is powered by XRANGE technology and therefore automatically detected by the receiver.

Li-Ion battery
Charge Li-Ion battery

Charge the Li-Ion battery before using it for the first time. While charging, the instrument may heat up. This is normal and should not affect the instrument´s lifespan or performance. At the recommended storage temperature of -20°C to +30°C (-4°F to +86°F), batteries containing a 50% to 100% charge can be stored up to 1 year. After this storage period the batteries must be recharged.

Connecting the charger using the wrong adapter may cause serious damage to the instrument. Any damage caused by misuse is not covered by warranty. Use only Leica-approved chargers, batteries and cables. Unapproved chargers or cables can cause the battery to explode or damage the instrument.

Insert Li-Ion battery

Insert the battery-pack by pressing it down and then tilting it towards the housing as shown until it snaps in.

Li-Ion status LED
The function of the Li-Ion status LED is indicated by the 3rd number in the 10-digit serial number on the type label of the Li-Ion battery.

Number 0, 1 or 2:

	lights green: charging battery
	OFF: charging finished / no charging

Number 3 or higher:

	blinks green: charging battery
	lights green: charging finished / no charging

Alkaline batteries
To ensure a reliable use, we recommend using high quality Alkaline batteries.

Insert Alkaline batteries

Insert Alkaline batteries in the battery-pack.

Insert the battery-pack

Insert the battery-pack by pressing it down and then tilting it towards the housing as shown until it snaps in.

Operations

Switching ON/OFF

Auto power-off
Place the lock switch to the unlocked position (see Levelling lock). To activate auto power-off after 30 min operation press and hold the On button at start for 5 sec. The status LED blinks 3 times in green colour. To deactivate it again repeat the described steps until the status LED blinks 3 times in red colour.

Horizontal line on

Vertical line on

Vertical and horizontal line
Checking the accuracy of the horizontal line

Place the lock switch in the "Unlocked" position (see Levelling lock). Position the instrument approx. 5 m away from the wall. Direct the instru- ment at the wall and switch on. Activate the 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 instrument is within tolerance.

Checking the accuracy of the vertical line

Place the lock switch in the "Unlocked" position (see Levelling lock). As a 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. 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 instrument is within tolerance.
Should your instrument be outside of the specified tolerance, please contact a local dealer or an authorised Leica Geosystems distributor.

Care

Never immerse the device in water. Wipe off dirt with a damp soft cloth. Never use aggressive cleaning agents or solvents. Treat the instrument with the same care that you would apply to bin- oculars or a camera. Dropping or violent shaking of the instrument may damage it. Check the instrument for any damage before using it. Check the levelling accuracy of the instrument regularly.
To warranty the best precision and visibility please clean the optics of your device regularly. Therefore blow off the dust from the glasses without touching the optics with your fingers. If necessary use a damp soft cloth and a little bit of pure alcohol.
To avoid wrong measurements also clean your adapters regularly. This could be done also by the proposed recommendation. Especially the interface between the adapter and device should always be clean to enable easy rotation. To clean the magnetic surface you could use compressed air or modelling clay.
If the equipment get wet always dry it (max. 70°C/158°F) before repacking it into the case.
