Batteries must be kept out of reach of children. Do not leave batteries lying around, as there
is risk that children or pets swallow them.
Batteries must always be replaced/exchanged at the same time. Mixing old and new batte-
ries in the device can lead to battery leakage and device damage.
Batteries must not be dismantled, short-circuited or thrown into open flames. Never attempt
to recharge non-rechargeable batteries. This may cause an explosion!
Make sure that the cable is not pinched, kinked or damaged by sharp edges.
Always lay cables so that nobody can trip over or become entangled in them. Risk of injury!
The product can be powered with rechargeable batteries. However, the operating
time is reduced due to the lower voltage (non-rechargeable battery = 1.5 V, rechar-
geable battery = 1.2 V).
We therefore recommend operating the product only with high-quality alkaline bat-
teries to ensure long and reliable operation.
6 Operating elements
1 Laser window
2 Power button with LED
(red and green)
3 Battery cover
4 Sliding switch
5 Tripod mount
7 Inserting / replacing batteries
Slide the battery cover on the rear of the cross-line
laser outwards (A), and then remove it carefully.
Insert three AAA batteries, observing the correct po-
larity. The positive pole is marked on the batteries
and the battery compartment.
Replace the cover and slide it until it clicks into place.
8 Operating the product
8.1 Using the tripod
The cross-line laser can be fastened to the supplied tripod via the tripod socket (5) on the
underside.
The height of the tripod can be adjusted. Align the tripod mounting plate horizontally with the
built-in level.
8.2 Using the automatic levelling system
Place the cross-line laser on a horizontal and stable sur-
face or mount it on a tripod.
Move the sliding switch (4) to the „closed lock" position. The
laser will switch on.
When the cross-line laser is outside the self-levelling range, the power button (2) will
light up red and the laser lines will flash.
The power button (2) will light up green when the cross-line laser is within the self-levelling
range of ±4°.
The levelling process is complete when the laser lines stop moving. You can now, for example,
mark a horizontal and/or a vertical line on the wall in order to lay tiles, etc.
To switch off the laser, move the sliding switch (4) to the „open lock" position.
The lasers will be disabled and the mechanics of the au-
tomatic levelling system inside the cross-line laser will be
fixed in place. The cross-line laser is now switched off.

8.3 Operating the laser without the automatic levelling system
This mode of operation can be used, for example, to project a diagonal line onto a wall in
Æ
order to mark the positions of several pictures on the wall.
You can hold the cross-line laser in your hand or use the supplied tripod to fix the cross-line
laser in a diagonally inclined position.
Press the power button (2). The laser is now switched on and ready for use.
To switch off the laser, press the power button (2) again.
When the automatic levelling system is switched off, the laser lines do not mark any
horizontal or vertical line, because the mechanical system inside the cross-line laser
cannot move freely and align itself!
8.4 LED status display
The LED on the power button indicates different operating statuses, which are shown in the
following table.

8.5 Checking the vertical line
Place the device approximately 5 m away from a wall. Fasten a plumb bob to the wall with a
4
2.5 m long cord and make sure that the plumb bob can swing freely. Switch on the device and
align the vertical laser with the plumb line. The accuracy is within the specified tolerance if the
distance between the laser line and the plumb line is not more than ± 2.5 mm.
8.6 Checking the horizontal line
5
Set up the device approximately 5 m from a wall and switch on the laser. Mark point B on the
wall. Turn the laser cross approximately 2.5 m to the right and mark point C. Check that the
distance between the horizontal lines to point C and point B is within ± 2.5 mm. Repeat the
process by turning the laser to the left.
8.7 Checking the calibration
To check the laser calibration, place the device in between 2 walls, which must be at least
5 metres apart. Turn the device on with automatic levelling enabled. For optimal calibration
results, mount the device on a tripod.
1. Mark point A1 on the wall.
2. Rotate the device 180° and mark point A2. You now have a horizontal reference between
points A1 and A2.
3. Place the device as close as possible to the wall at the height of point A1.
4. Rotate the device 180° and mark point A3. The difference between points A2 and A3 is
the tolerance.
If A2 and A3 are more than 0.5 mm/m apart, adjustment is required (at a distance
of 4 m, this corresponds to value of 2 mm). In this event, contact your authorised
dealer.
