A) The working range may be reduced by unfavourable environ-
mental conditions (e.g. direct sunlight).
B) At 20–25 °C
C) The values stated presuppose normal to favourable environ-
mental conditions (e.g. no vibration, no fog, no smoke, no direct
sunlight). Extreme fluctuations in temperature can cause devi-
ations in accuracy.
D) Only non-conductive deposits occur, whereby occasional tem-
porary conductivity caused by condensation is expected.
The serial number (4) on the type plate is used to clearly identify your
measuring tool.
Assembly
Inserting/Changing the batteries
It is recommended that you use alkaline manganese or re-
chargeable batteries to operate the measuring tool.
To open the battery compartment cover
(6) , press the lock-
ing mechanism (7) and lift open the battery compartment
cover. Insert the batteries/rechargeable batteries.
When inserting the batteries, ensure the polarity is correct
according to the representation on the inside of the battery
compartment cover
(6) .
Always replace all the batteries at the same time. Only use
batteries from the same manufacturer and which have the
same capacity.
u
Take the batteries out of the measuring tool when you
are not using it for a prolonged period of time
. The bat-
teries can corrode and self-discharge during prolonged
storage.
Operation
Starting Operation
u
Protect the measuring tool from moisture and direct
sunlight.
u
Do not expose the measuring tool to any extreme tem-
peratures or fluctuations in temperature.
For example,
do not leave it in a car for extended periods of time. If it
has been subjected to significant fluctuations in temper-
ature, first allow the measuring tool to adjust to the ambi-
ent temperature and then always carry out an accuracy
check before continuing work (see "Accuracy Check of
the Measuring Tool", page 10).
The precision of the measuring tool may be compromised
if exposed to extreme temperatures or fluctuations in
temperature.
u
Avoid substantial knocks to the measuring tool and
avoid dropping it.
Always carry out an accuracy check
before continuing work if the measuring tool has been
subjected to severe external influences (see "Accuracy
Check of the Measuring Tool", page 10).
u
Switch the measuring tool off when transporting it.
The pendulum unit is locked when the tool is switched off,
as it can otherwise be damaged by big movements.
Switching On/Off
To switch on the measuring tool, slide the on/off switch (2)
to the " On " position. As soon as it is switched on, the meas-
uring tool emits laser lines from the outlet apertures (1) .
u
Do not direct the laser beam at persons or animals and
do not stare into the laser beam yourself (even from a
distance).
To switch off the measuring tool, slide the on/off switch (2)
to the Off position. The pendulum unit is locked when the
tool is switched off.
u
Never leave the measuring tool unattended when
switched on, and ensure the measuring tool is
switched off after use.
Others may be blinded by the
laser beam.
Operating Modes
Once the measuring tool has been switched on, it is in cross-
line operation with automatic levelling.
To change the operating mode, press the
Mode button for
laser operating mode (9) until the required laser operating
