OPERATION INSTRUCTIONS

IMPORTANT: The working range can be
decreased by unfavorable environmental con-
ditions (e.g. direct sun radiation).
Please observe the article number on the type
plate of your measuring tool. The trade names
of the individual measuring tools may vary.
ASSEMBLY
Inserting/Replacing the Battery
NOTE: Alkali-manganese batteries are recom-
mended for the measuring tool.
To open the battery lid , press on the latch and
fold the battery lid up. Insert the batteries.
When inserting, pay attention to the correct
polarity according to the representation on the
inside of the battery compartment.
Always replace all batteries at the same time.
Only use batteries from one brand and with
the identical capacity.
Remove the batteries from the measuring tool
when not using it for extended periods. When
storing for extended periods, the batteries can
corrode and discharge themselves.

INITIAL OPERATION

Protect the measuring tool against moisture
and direct sun light.
• Do not subject the measuring tool to extreme
temperatures or variations in temperature. As
an example, do not leave it in vehicles for lon-
ger periods. In case of large variations in tem-
perature, allow the measuring tool to adjust
to the ambient temperature before putting it
into operation.
• Avoid heavy impact to or falling down of
the measuring tool. Damage to the measuring
tool can impair its accuracy. After heavy impact
or falling down, check the angle accuracy be-
tween the 0° and 90° laser line with the angle
of a precision square.

SWITCHING ON AND OFF

To switch on the measuring tool, briefly press
the On/Off switch . Immediately after switch-
ing on, the measuring tool sends out the two
laser lines at 0 ° and 90°.
Do not point the laser beam at persons or
animals and do not look into the laser beam
yourself, not even from a large distance.

To switch off the measuring tool, push the On/
Off switch again.
Do not leave the switched on measuring tool
unattended and switch the measuring tool off
after use. Other persons could be blinded by
the laser beam.

WORKING ADVICE

WARNING: Always place the measuring
tool level on the floor or fasten it plane against
the wall. When placing down or fastening un-
evenly, the angle will not be precisely 90 °.
· Always use the centre of the laser line for
marking. The width of the laser line changes
with the distance.
· Never use the laser lines that the measuring
tool standing on the floor projects on the
wall for alignment. The measuring tool is not
self-levelling. Therefore, the line on the wall is
distorted.
· The reference point for alignment of tiles is
the intersecting point P of the laser lines, di-
rectly in front of the measuring tool. To project
an angle, the measuring tool must be rotated
at this intersecting point.
· Position the measuring tool only on a clean
wall holder.
· The measuring tool cannot stand level on an
uneven, soiled wall holder surface, which could
lead to faulty measuring results.
Positioning the Measuring Tool
When working on the floor, place down the
measuring tool with the bottom plate facing
the floor. Place the T-edge of the tool against
a wall so that the 0° laser line runs parallel to
the reference line (e.g. a wall), see figure A.
Measure the clearance between laser line and
reference line directly at the measuring tool
and as far away as possible from the measuring
