Assembly
Inserting/Changing the Batteries
It is recommended that you use alkaline manganese batteries to operate the measuring
tool.
Press the locking mechanism (4) upwards to open the battery compartment cover (5)
and remove the battery compartment cover. Insert the batteries.
When inserting the batteries, ensure that the polarity is correct according to the illustra-
tion on the inside of the battery compartment.
If the batteries are running low, the laser lines will flash intermittently (in a blinking se-
quence of 0.3 s off, 0.3 s on, 0.3 s off, 0.3 s on, 0.3 s off, 1 min on).
Always replace all the batteries at the same time. Only use batteries from the same man-
ufacturer and which have the same capacity.
Take the batteries out of the measuring tool when you are not using it for a pro-
u
longed period of time. The batteries can corrode and self-discharge during pro-
longed storage.
Operation
Start-up
Protect the measuring tool from moisture and direct sunlight.
u
Do not expose the measuring tool to any extreme temperatures or variations in
u
temperature. For example, do not leave it in a car for extended periods of time. In
case of large variations in temperature, allow the measuring tool to adjust to the ambi-
ent temperature before putting it into operation. The precision of the measuring tool
may be compromised if exposed to extreme temperatures or variations in temperat-
ure.
Avoid substantial knocks to the measuring tool and avoid dropping it. Always
u
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).
Switch the measuring tool off when transporting it. The pendulum unit is locked
u
when the tool is switched off, as it can otherwise be damaged by big movements.
