Introduction
The safety instructions (see Safety Instructions)
and the user manual should be read through carefullybefore 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:
WARNING
Indicatesa potentiallyhazardous situation or an
unintended use which, if not avoided, will result in
death or serious injury.
CAUTION
Indicatesa potentiallyhazardous 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
See alsoLevelling the instrument
Level ling unlock ed
In the unlockedpositionthe instrument automatically levelsitself within the specified inclination range. (See Technicaldata)
Level ling lock ed
Turn the levelling lock in or der to transport or tilt
the instrument beyond the self-levelling range.
When locked, the pendulum is fixed and the selflevelling function isdeactivated. In this case the
laser blinks every 3sec.

Instrument Set-up
Laser receiver
To be able to detect the laser lines over long distances
(>15 m) or in unfavourable lighting conditions, a
laser receiver can be used.
We recommend the Leica RVL80 laser
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, 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.

Accuracy Check
Accu racyCh eck
Check the accuracy of your Leica Lino L4P1
regularly and particularlybefore 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 lockswitchin the "Unlocked" position. Direct
the instrument at wall A and switch on the instrument. Activate the horizontallaser line or laser
point and mark the position 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 distances of the marked pointsA1-A2 and B1-B2.
Calculate the difference of the two measurements.
|(A1 - A2) - (B1 - B2)| <=2 mm
If the difference does not exceed 2 mm, then the
Leica Lino L4P1 iswithin tolerance.

Accuracy Check
Vertical and horizontal line
Checking the accuracy of the horizontal line
Placethe lockswitch in the "Unlocked" position.
Position the instrument approx. 5 m away from the
wall. Direct the instrument at the wall and switch
on. Activate the laser lineand 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 L4P1 is within
tolerance.
Checking the accuracy of the vertical line
Placethe lockswitch in the "Unlocked" position. 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 wallat an elevation of approx. 1.5 m. Direct the instrument at the walland 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 3 mm, then
the Leica Lino L4P1 iswithin tolerance.
Vertical plumb points
Checking the accuracy of the upper plumb
point:
Set up the laser on its tr ipod o wallmount bracket
near point A1 at a minimum distance of 1.5 m from
point B1. The horizontal laser is aligned in direction 1. Mark the laser points A1 and B1 with a
pin.
Checking the accuracy of the lower plumb
point:
Leica Lino L4P1

Page 13
Accuracy Check
Rotate the instrument by 180° so that it points in
the opposite direction 2 to direction 1. Adjust the
instrument so that the laser beam hits point A1
exactly. If point B2 is no further than 2 mm away
from point B1, then the Leica Lino L4P1 is within
tolerance.

Care
Care
Never immerse the device in water. Wipe off dirt
with a damp soft cloth. Never use aggressive
cleaning agents or solvents. Tr eat the instrument
with the same care that you would apply to binoculars or a camera. Dropping or violent shaking
of the instrument may damage it. Checkthe instrument for any damage before using it. Check the
levelling accuracy of the instrument regularly.
