OPERATION INSTRUCTIONS

IMPORTANT: The working range can be
decreased by unfavorable environmental con-
ditions (e.g. direct sun radiation).
Please observe the article number on the type
plate of your measuring tool. The trade names
of the individual measuring tools may vary.
ASSEMBLY
Inserting/Replacing the Battery
NOTE: Alkali-manganese batteries are recom-
mended for the measuring tool.
To open the battery lid 10 ,slide it in the direc-
tion of the arrow away from the battery com-
partment. Insert the batteries provided. When
inserting,pay attention to the correct polarity
according to the representation on the inside
of the battery compartment.
Always replace all batteries at the same time.
Only use batteries from one brand and with
the identical capacity.
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.
INITIAL OPERATION
Protect the measuring tool against moisture
and direct sun light.
• Do not subject the measuring tool to extreme
temperatures or variations in temperature. As
an example, do not leave it in vehicles for lon-
ger periods. In case of large variations in tem-
perature, allow the measuring tool to adjust
8
to the ambient temperature before putting it
into operation.
• Avoid heavy impact to or falling down of
the measuring tool. Damage to the measuring
tool can impair its accuracy. After heavy impact
16
or falling down, check the angle accuracy be-
tween the 0° and 90° laser line with the angle
17
of a precision square.
SWITCHING ON AND OFF
To switch on the measuring tool in line op-
eration, push the On/Off switch 1 forward . To
switch on the measuring tool in point opera-
tion, push the On/Off switch 1 back.
Immediately after switching on, the measuring
tool sends a laser beam out of outlet opening
5 (line operation) or 6 (point operation), de-
pending on the selected operating mode.
· Do not point the laser beam at persons or
animals and do not look into the laser beam
yourself, not even from a large distance.
To switch off the measuring tool, push the on/
off switch 1 to the center position.
· Do not leave the switched on tool unattended
and switch the tool off after use. Other persons
could be blinded by the laser beam.
When not using the measuring tool,switch it
off in order to extend the battery life.
LEVELING FUNCTION
NOTE: The specified leveling accuracy applies
for the alignment of the laser beam with refer-
ence to the spirit levels 3 and 4.
If spirit level leaks, soak up with appropriate
absorbent material and dispose of safely. Spirit
levels contain flammable liquid that may cause
respiratory tract, eye and skin irritation.
OPERATION
Position the Tool (see figure B)
For precise alignment with the spirit levels, the
position of the- tool is important.
The specified leveling accuracy is only achieved
when the tool is correctly positioned:
For horizontal alignment with spirit level 4, the
laser outlet opening for line operation 5 must
be horizontal and the aluminium supporting
surface 2 of the measuring tool must face
downward. For vertical alignment with spirit
