Overview
Overview
The Leica Lino L2/L2G is a self-levelling cross-
line 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 ver-
tical and horizontal lines.

Introduction
The safety instructions (see Safety Instruc-
tions) 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 dir-
ections and adhere to them.
The symbols used have the following meanings:
WARNING
Indicates a potentially hazardous situation or an
unintended use which, if not avoided, will result in
death or serious injury.
CAUTION
Indicates a potentially hazardous situation or an
unintended use which, if not avoided, may result
in minor injury and/or appreciable material, fin-
ancial 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 auto-
matically 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 self-
levelling function is deactivated. In this case the
laser blinks every 5sec.

Instrument Set-up
Laser receiver
To be able to detect the laser lines over long dis-
tances 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.
CAUTION
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, bat-
teries and cables. Unapproved chargers or
cables can cause the battery to explode or dam-
age the instrument.

Accuracy Check
AccuracyCheck
Check the accuracy of your instrument reg-
ularly and particularly before important
measuring tasks. Check Levelling lock
before checking the accuracy.
Levelling
Checking the accuracy of the levelling
Set the instrument on a tripod half-way between
two walls (A+B) that are approx. 5 m apart. Place
the lock switch in the "Unlocked" position (see
Levelling lock). Direct the instrument at wall A
and switch on the instrument. Activate the hori-
zontal laser line or laser point and mark the pos-
ition of the line or the point on wall (A1). Rotate
the instrument by 180° and mark the horizontal
laser line or the laser point in exactly the same
way on wall (B1).
Then place the instrument at the same elevation
as close as possible to wall A and again mark the
horizontal laser line or the laser point on wall A
(A2). Rotate the instrument by 180° again and
mark the laser on wall B (B2). Measure the dis-
tances of the marked points A1-A2 and B1-B2.
Calculate the difference of the two meas-
urements.
|(A1 - A2) - (B1 - B2)| <=2 mm
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.

Accuracy Check
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
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.
