Operation

Charging the battery

The battery is partially charged upon delivery to avoid damage
to the battery caused by a deep discharge.

Info

Upon delivery, the battery is only slightly charged.
Therefore, please charge the battery for at least
5hours before using the device for the first time.

Warning of laser radiation
Laser class2, Pmax.: <1mW, λ: 650nm,

EN60825-1:2014

Do not look directly into the laser beam or the opening
from which it emerges.
Never point the laser beam at people, animals or
reflective surfaces. Even brief eye contact can lead to
eye damage.
Examining the laser output aperture by use of optical
instruments (e.g. magnifying glass, magnifiers and the
like) entails the risk of eye damage.
When working with a laser of class2, observe the
national regulations on wearing eye protection.

3. Connect the charging cable to the device's micro USB port.

4. During charging, the levelling indicator "NO Level"(9) is
illuminated in red.

5. When the battery is fully charged, the levelling indicator
"Level"(8) lights up in green.

Switching the device on

The device has twodifferent modes of operation. On the one
hand, you can use the device with the automatic self-levelling
function, on the other, it is possible to set the laser to a fix
position.

Warning of electrical voltage

Before each use of the charger or power cable, check
for damages. If you notice damages, stop using the
charger or power cable!

Note

The battery can be damaged in case of improper
charging.
Never charge the battery at ambient temperatures
below 10°C or above 40°C.

The battery should be charged prior to initial start-up and when
the battery is low. To do so, please proceed as follows:

1. Unscrew the device from the multifunctional mount.

2. Plug the charger into a properly fused mains socket.

Self-levelling function of the laser

1. Place the device on a horizontal, solid surface or secure it
to the multifunctional mount.

2. Slide the on/off switch(7) to to switch the device on.

ð Both the vertical laser and the horizontal 360° laser

switch on.

ð The device automatically compensates for unevenness

within the self-levelling range of ± 3°. During levelling,
the laser lines move.

ð When levelling is completed, the levelling indicator

"Level"(8) lights up in green.

Info

1x

2x

When exceeding the permissible inclination range of
3°, the lasers begin to flash and the levelling indicator
"NO Level"(9) will be illuminated in red. If so, self­levelling will not function properly. This may be due to
the fact that the surface structure is not even enough
or covered with dirt, so the device is positioned too
obliquely to be able to self-level within the possible
angle of 3°. Check the surface, and reposition the
device if required.

3. Press the operating mode button(6) to activate the vertical
laser only or the horizontal 360° laser only.

Using the multifunctional mount

Proceed as follows to use the multifunctional mount with the
device:

1. Screw the mount into the tripod connection at the device.

By means of the suction cup you can affix the mount to smooth
surfaces such as tiles or glass.

Alternatively, the clamping jaws can be used to fasten it to a
shelf or the edge of a table.

4. Slide the on/off switch(7) back to to switch the device
off.

Fixed position of the lasers

Info

In this operating mode the device's self-levelling
function is deactivated.

1. Check whether the lock switch(7) is set to .

2. Press the operating mode button(6) to switch both lasers
on.

3. Press the operating mode button(6) a second time to only
activate the horizontal laser.

4. Press the operating mode button(6) a third time to only
activate the vertical laser.

5. Press the operating mode button(6) a fourth time to switch
the device off.

Swivelling the device

1. Loosen the wing nut(11).

2. Swivel the device on the ball joints to move it into the
desired position.

3. Retighten the wing nut(11).

EN 7

cross line laser BD7A

Application example for the universal clamp

1. Loosen the locking screw(12) and push the clamping
jaws(15) apart until they fit onto the carrier (here: shelf).

Application example for the suction cup

1. Make sure that the surface is smooth and clean.

2. Disengage the lever(13) at the suction cup(14).

2. Tighten the screw(12) until the jaws(15) of the universal
clamp are firmly attached to the carrier and the mount can
no longer be moved to and fro.

3. To unfasten the clamping jaws(15), loosen the screw(12)
until the retainer can be removed from the carrier without
difficulty.

3. Press the suction cup(14) against the surface (here: tiles).

4. Engage the lever(13) until it locks in place.

5. Check the suction cup(14) for tight fit.

6. In order to remove the suction cup(14) again, release the
lever(13), then pull at the lug of the suction cup.

Maintenance and repair

Li-Ion

Charging the battery

The battery should be charged prior to initial start-up and when
the battery is low. To do so, please follow the instructions in the
chapter Operation.

Cleaning

Clean the device with a soft, damp and lint-free cloth. Make
sure that no moisture enters the housing. Do not use any
sprays, solvents, alcohol-based cleaning agents or abrasive
cleaners, but only clean water to moisten the cloth.

Repair

Do not modify the device or install any spare parts. For repairs
or device testing, contact the manufacturer.

Errors and faults

The device has been checked for proper functioning several
times during production. If malfunctions occur nonetheless,
check the device according to the following list.

Self-levelling is not possible:

1. Check whether the lock switch(7) is released and the laser
can move freely. If the laser is not able to move back and
forth freely within the 3° angle despite the lock switch
being released, please contact the customer service.

2. Check the surface on which the device is placed.
If necessary, remove coarse dirt.

Laser lines are not properly horizontal/vertical:

• Check the laser for freedom of movement in self-levelling
mode. If the laser is not able to move back and forth freely
within the 3° angle despite the lock switch being released,
please contact the customer service.

Horizontal laser lines are partially interrupted:

• The lateral struts of the protective cover accommodating
the laser cause interruptions in the horizontal 360° laser
line at defined points. This cannot be avoided. Should you
detect interruptions at other points, please check the glass
covers of the protective cover for scratches or dirt, which
may be the cause of the laser beam interruptions. Remove
external dirt with a damp cloth. Do not use any aggressive
cleaning agents (see chapter Cleaning)! If you detect dirt
underneath the glass covers or scratches, please contact
the customer service.

Laser is weak:

• Check the battery status and recharge the battery if
necessary.

Disposal

The icon with the crossed-out waste bin on waste
electrical or electronic equipment stipulates that this equipment
must not be disposed of with the household waste at the end of
its life. You will find collection points for free return of waste
electrical and electronic equipment in your vicinity. The
addresses can be obtained from your municipality or local
administration. For further return options provided by us please

The separate collection of waste electrical and electronic
equipment aims to enable the re-use, recycling and other forms
of recovery of waste equipment as well as to prevent negative
effects for the environment and human health caused by the
disposal of hazardous substances potentially contained in the
equipment.

In the European Union, batteries and accumulators must not be
treated as domestic waste, but must be disposed of
professionally in accordance with Directive 2006/66/EC of the
European Parliament and of the Council of 6September 2006
on batteries and accumulators. Please dispose of batteries and
