Assembly
Inserting/Changing the batteries
It is recommended that you use alkaline manganese batteries to operate the measuring
tool.
To open the battery compartment cover (9), press on the locking mechanism (8) and re-
move 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 become weak, the battery warning (4) will light up red.
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 in the measuring tool.
Operation
Starting Operation
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. Damaging
u
the measuring tool can cause accuracy to be compromised. If the laser line is subjec-
ted to a substantial knock or is dropped, check it by comparing it to a known hori-
zontal or vertical reference line.
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.
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 measuring tool emits laser beams from the outlet apertures (1).
