compromised. Following a hard knock or fall, carry out a 
check by comparing the laser lines or plumb beams with a 
known horizontal or vertical reference line or verified per-
pendicular points.



Switch the measuring tool off during transport. 

When 

switching off, the levelling unit, which can be damaged in 
case of intense movement, is locked.

Setting Up the Measuring Tool

Set up the measuring tool on the floor surface to be checked, 
ensuring that it is firmly positioned.

The levelling accuracy can be influenced through the ambient 
temperature. Especially temperature differences occurring 
from the ground upward can deflect the laser beam. As the 
thermal layering is greatest at ground level, the measuring 
tool should always be set up in the centre of the floor surface 
to be checked.

Switching On and Off

To 

switch on

 the measuring tool, slide the On/Off switch 

8

 to 

the 

“On”

 position. Immediately after switching on, the meas-

uring tool sends laser beams out of the exit openings 

1

.



Do not direct the laser beam at persons or animals (es-
pecially not at their eye level), and do not stare into the 
laser beam yourself (not even from a distance).

To 

switch off

 the measuring tool, slide the On/Off switch 

8

 to 

the 

“Off”

 position. When switching off, the levelling unit is 

locked.

When the measuring tool is not moved or remote-controlled 
for approx. 30 minutes, it switches off automatically to save 
the batteries or the battery pack.

After switching off automatically, switch the measuring tool 
off via On/Off switch 

8

 and then on again, if required.

GSL 2 Set: After switching off automatically, the measuring 
tool can be switched on again by pressing any button on the 
remote control.



Do not leave the switched-on measuring tool unattend-
ed and switch the measuring tool off after use. 

Other 

persons could be blinded by the laser beam.

When exceeding the maximum permitted operating tempera-
ture of 50 ° C, the measuring tool switches off to protect the 
laser diode. After cooling down, the measuring tool is ready 
for operation and can be switched on again.

Operation with battery pack: 

The “Electronic Cell Protec-

tion (ECP)” protects the lithium-ion battery pack against deep 
discharging. When the battery pack is discharged, the meas-
uring tool is switched off by a protective circuit.
When the measuring tool switches off automatically due to a 
discharged battery pack, switch the measuring tool off with 
the On/Off switch 

8

. Charge the battery pack before switch-

ing the measuring tool on again. Otherwise, the battery pack 
could become damaged.

Allowing the Measuring Tool to Level In

After switching on, the levelling function automatically com-
pensates irregularities within the self-levelling range of ± 4 °. 
The levelling is finished as soon as the laser beams do not 
move any more.

If the automatic levelling function is not possible, e. g. 
because the surface on which the measuring tool stands 
deviates by more than 4 ° from the horizontal plane, the laser 
beams flash.

Set up the measuring tool in level position and wait for the 
self-levelling to take place. As soon as the measuring tool is 
within the self-levelling range of ± 4 °, the laser beams light up 
continuously.

In case of ground vibrations or position changes during oper-
ation, the measuring tool is automatically levelled in again, 
yet, possibly to a different height when larger position chang-
es are the case. Upon re-levelling, check if the two laser 
beams are aligned at the reference point (see “Aligning the 
Height of the Measuring Tool”, page 16) in order to avoid ver-
tical errors.

Aligning the Height of the Measuring Tool

The measuring tool generates two laser beams that can be 
seen on the floor surface in front of the measuring tool for dis-
tances beyond 50 cm. The beams must be brought into align-
ment at this reference point, where they can initially be seen 
on the floor surface. For this, turn the thumbwheel for height 
adjustment 

9

 clockwise or anticlockwise, until both laser 

beams overlap at the reference point and only one beam can 
be seen.

When the two laser beams cannot be aligned by turning the 
thumbwheel, the position of the measuring tool is significant-
ly above or below the floor surface. Position the measuring 
tool at a different location on the floor surface with less height 
deviation and align the laser beams there.

Starting Operation of the Remote Control 
(GSL 2 Set)



Protect the remote control against moisture and direct 
sunlight.



Do not subject the remote control to extreme tempera-
tures or variations in temperature. 

As an example, do 

not leave it in vehicles for longer periods. In case of large 
variations in temperature, allow the remote control to ad-
just to the ambient temperature before putting it into oper-
ation.

The remote control remains ready for operation as long as a 
battery with sufficient voltage is inserted.

The signals of the remote control should reach the reception 
lens 

4

 directly from the front and inclined from above. When 

the remote control cannot be pointed directly against a recep-
tion lens, the working range is reduced. By reflecting the sig-
nal (e. g. against walls), the working range can be improved, 
even for indirect signals.

Switching the measuring tool on via the remote control after 
automatic shut-off of the measuring tool is only possible when 
the On/Off switch 

8

 is still in the 

“On”

 position. Switching the 

measuring tool off with the remote control is not possible.
