Instrument Set-up
Ins trume n tSet-up
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, 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 auto-
matically levels itself within the specified inclin-
ation 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.
Leica Lino L2/L2G 4

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 instru-
ment´s lifespan or performance. At the recom-
mended 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 war-
ranty. Use only Leica-approved chargers, bat-
teries and cables. Unapproved chargers or cables
can cause the battery to explode or damage the
instrument.

Accuracy Check
Ac c u rac y Ch e c k
Check the accuracy of your Leica Lino reg-
ularly and particularly before important meas-
uring 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 Lev-
elling lock). Direct the instrument at wall A and
switch on the instrument. Activate the horizontal
laser line or laser point and mark the position of
the line or the point on wall (A1). Rotate the instru-
ment 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
Leica Lino is within tolerance.
Should your Leica Lino be outside of the spe-
cified tolerance, please contact a local dealer
or an authorised Leica Geosystems dis-
tributor.
Leica Lino L2/L2G 12

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 devi-
ation 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
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 Leica Lino is within tolerance.
Should your Leica Lino be outside of the spe-
cified tolerance, please contact a local dealer
or an authorised Leica Geosystems dis-
tributor.

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 instru-
ment 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. There-
fore 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 inter-
face 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.
