E N G L I S H
• Use the keys (20) to move the laser head until the
laser line aligns with the position mark (fig. A).
Slope alignment (fig. A)
If the application requires the laser line to align at
a slope angle, proceed as follows:
• With the tool switched on and the laser head
rotating, activate the manual leveling mode.
• Align the laser line with the slope:
– Use the keys (20) to adjust the tool in the X-axis.
– Use the keys (21) to adjust the tool in the Y-axis.
Instructions for use
• Always observe the safety instructions
and applicable regulations.
• Always mark the center of the laser line or dot.
• To increase working distance and accuracy,
set up the tool in the middle of your working area.
• Extreme temperature changes cause movement
of internal parts that may affect the accuracy of
the tool. Regularly check the accuracy while
using the tool under these circumstances.
• Although the tool corrects small out-of-level
errors automatically, when it has registered a
bump, re-adjustment to balance or set-up may
be required.
• If the tool has been dropped or has tipped over,
have the laser head calibrated by a qualified
repair agent.
• For your own comfort, always use the remote
control to operate the tool. The remote control
not only allows you to operate the tool from a
distance, it also keeps you from touching the
tool, thereby reducing the risk of affecting the
tool's balance and set-up.
Prior to operation:
• Carry out the field calibration checks to confirm
its accuracy.
• Make sure the tool has been set up securely.
Switching on and off (fig. A)
• To switch the tool on, press the on/off switch (1).
• To switch the tool off, press the on/off switch (1)
again.

Setting the rotation speed (fig. G)
The laser head can be set to different rotation speed
settings, thus determining the quality of the line.
• Press the key (19). The rotation speed will cycle
from "fast" to "medium", "slow", "crawling" and
"stationary" each time the key is pressed.
• For a bright line, set the laser head to a slow
rotation speed.
• For a solid line, set the laser head to a fast
rotation speed.
Rotating the laser head (fig. H1 & H2)
In the stationary position, the laser head can be
moved both to the left and to the right.
Level applications:
• Use the keys (20) to move the laser head into the
required direction.
Plumb applications:
• Use the keys (21) to move the laser head into the
required direction.
Manually rotating the laser head (fig. H2)
The laser head can also be rotated manually.
• Turn the laser head (10) into the required position.
Do not attempt to move the laser head
while it is rotating at a preset rotation
speed.
Scan mode (fig. I)
The laser head can be set to different speed settings
while moving back and forth, thus projecting
a scanning laser line.
• Press the key (18) to activate the scan mode.
The scan speed starts at "fast" rate.
• To set the scan speed press the key (19). The
scan speed will cycle from "crawling" to "slow",
"medium" and "fast" each time the key is pressed.
• Level applications:
– Use the keys (20) to move the scan area into
the required direction.
– Use the keys (21) to adjust the scan area.
• Plumb applications:
– Use the keys (21) to move the scan area into
the required direction.
• Press the key (18) to discontinue the scan mode.
