Assembly

Inserting/Replacing the Battery

Use only alkali-manganese batteries.

Press the latch 

9

 of the battery lid outward with a suitable tool and 

open the battery lid 

10

.

When inserting batteries, pay attention to the correct polarity ac-

cording to the representation on the inside of the battery compart-

ment.

When the direction indicators 

4

 and 

2

 flash alternately, the batter-

ies must be replaced.

Always replace all batteries at the same time. Only use batteries 

from one brand and with the identical capacity.

f

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.

Operation

Initial Operation

f

Do not subject the measuring tool to extreme temperatures or 

variations in temperature. 

As an example, do not leave it in ve-

hicles for longer periods. In case of large variations in tempera-

ture, allow the measuring tool to adjust to the ambient temper-

ature before putting it into operation.

Position the measuring tool at least 50 cm away from the laser level 

and in such a manner that the laser beam can reach the reception 

area 

6

. Set the highest rotational speed on the laser level.

Switching On and Off

f

A loud audio signal sounds when switching on the measuring 

tool. Therefore, keep the measuring tool away from your ear 

or other person when switching on. 

The loud audio signal can 

cause hearing defects.

For 

switching on

 the measuring tool, briefly press button 

5

(“<1 sec on

”

). The direction indicators 

4

, 

3

 and 

2

 on the front and 

rear side of the measuring tool light up for one second and a brief 

audio signal sounds.

To indicate the operational readiness, the centre indicator 

3

 lights 

up every 2 seconds when the receiver is switched on. As soon as 

the laser beam runs through the reception area 

6

, the direction in-

dicators 

4

, 

3

 and 

2

 indicate only the height of the laser beam (see 

“Direction Indicators

”

, page 20).

To 

switch off

 the measuring tool, press button 

5

 for more than one 

second (“>1 sec off

”

). The switching off of the measuring tool is in-

dicated by the three direction indicators 

4

, 

3

 and 

2

 lighting up, and 

a brief audio signal sounds.

When no pushbutton on the measuring tool is pressed for approx. 

30 minutes and when no laser beam is impinged upon the recep-

tion area 

6

 for 30 minutes, the measuring tool switches off auto-

matically to save the batteries.

Direction Indicators

The direction indicators for bottom 

4

, centre 

3

 and top 

2

 (on both 

the front and rear side of the measuring tool) as well as the audio 

signal indicate the position of the rotating laser beam in the recep-

tion area 

6

.

When the laser beam runs through the reception area 

6

 the first 

time, a single tone is signalled, even when the audio signal is 

switched off.

Laser beam too high:

 When the laser beam runs through the upper 

half of the reception area 

6

, the direction “bottom

”

 indicator 

4

flashes. When the audio signal is switched on, a slow pulsing signal 

sounds. In this case, move the measuring tool upward in the direc-

tion of the arrow.

Laser beam too low:

 When the laser beam runs through the lower 

half of the reception area 

6

, the direction “top

”

 indicator 

2

 flashes. 

When the audio signal is switched on, a fast pulsing signal sounds. 

In this case, move the measuring tool downward in the direction of 

the arrow.

Laser beam centred:

 When the laser beam runs through the recep-

tion area 

6

 at the height of the centre mark 

7

, then the centre indi-

cator 

3

 flashes. When the audio signal is switched on, a continuous 

signal sounds.

Audio Signal

The audio signal can be switched on and off. For this, briefly press 

pushbutton 

5

 once (“<1 sec

”

).

When the audio signal is switched on and off, the direction indica-

tors 

4

, 

3

 and 

2

 light up briefly. When switching on, three audio sig-

nals sound; when switching off, a single audio signal sounds.

When the laser beam runs through the reception area 

6

 the first 

time, a single tone is signalled, even when the audio signal is 

switched off.

After the measuring tool has been switched on, the audio signal is 

always switched on.

Operating Instructions

Marking

The height of the laser beam can be marked at the centre mark 

7

on the right and left of the measuring tool when it runs through the 

centre of the reception area 

6

. The centre mark is 50 mm away 

from the upper edge of the measuring tool.

Aligning with the Spirit Level

The measuring tool can be aligned vertically (plumb line) with the 

spirit level 

1

. A measuring tool applied out-of-level leads to faulty 

measurements.

Attaching with the Holder (see figure A)

With the holder 

14

, the measuring tool can be fastened to a con-

struction laser measuring rod 

16

 (accessory) as well as to other 

auxiliary tools with a width of approx. 5 to 50 mm.

Slide the holder 

14

 sidewards into the retainer openings 

8

 on the 

rear side of the measuring tool until it can be heard to latch.

Loosen the locking screw 

17

, slide the holder onto the construc-

tion laser measuring rod 

16

, for example, and retighten the locking 

screw 

17

.

The upper edge 

15

 of the holder is located at the same height as 

the centre mark 

7

 and can be used for marking of the laser beam.

To remove the measuring tool from the holder 

14

, press the holder 

latch 

13

 and pull the measuring tool out of the holder.

Attaching with the Magnet (see figure B)

When a positive-lock attachment is not absolutely required, the 

measuring tool can be attached to steel parts via the face and rear 

side using the magnet plate 

12

.
