Note: The battery low indicator d on the display does not refer to the laser
batteries.
Make sure to switch the laser off before changing the batteries. An
accidentally switched on laser can blind other persons.
Always replace all batteries intended for laser operation at the same time.
Only use same-brand battery with the identical battery capacity.
Operation
Initial Operation
Protect the measuring tool against moisture and direct sun light.
Do not subject the measuring tool to extreme temperatures or vari-
ations in temperature. As an example, do not leave it in vehicles for long
time. In case of large variations in temperature, allow the measuring tool
to adjust to the ambient temperature before putting it into operation. In
case of extreme temperatures or variations in temperature, the accuracy
of the measuring tool can be impaired.
Avoid heavy impact to or falling down of the measuring tool. After
severe exterior effects to the measuring tool, it is recommended to carry
out an accuracy check (see "Accuracy Check and Calibration of the
Measuring Tool", page 18) each time before continuing to work.
Keep the supporting surfaces of the measuring tool clean and pro-
tect them against impact and shock. Debris particles or deformations
can lead to faulty measurements.
Setting Up/Attaching the Measuring Tool
To measure or transfer grades, the measuring tool can not only be placed on
or against surfaces, but can also be set up or fastened in various ways.
Setting up with the levelling mechanics (e.g. on uneven floors)
(see figure B):
– Briefly press against the pedestal 16 to extract it. Press button 8 to ex-
tract the levelling foot 17. Adjust the height of the levelling foot by turn-
ing adjusting screw 9 so that the laser beam runs along the surface to be
measured or the desired grade is displayed as the measuring value b.
– For work without levelling mechanics, retract pedestal 16 and levelling
foot 17. For this, press both parts of the pedestal ( ) together and then
slide the pedestal 16 into the measuring tool ( ) until it can be heard to
engage. To retract the levelling foot 17, press switch 10 sideways.
Fastening to the tripod:
– Position the measuring tool with the 1/4" tripod mount 18 onto the quick-
change plate of the tripod 26 or a commercially available camera tripod.
Tighten the measuring tool with the quick-change plate locking screw.
Attachment with magnets:
– Place the measuring tool against an adequate magnetic object via the
magnets 14.
Check the secure attachment of the measuring tool. Improperly secured
measuring tools can fall down and cause injury to yourself or other persons.
A falling down measuring tool can become damaged or cause damage.
Attachment with fastening straps (see figure C):
– Thread the fastening straps 25 through the openings 15 and attach the
measuring tool with both straps to a pipe or similar. Pay attention that
the Velcro attachment of the strap end is pressed against the fastening
strap. For thin pipes, thread the fastening strap through the openings
with the smooth side facing outward and wrap it once more around the
measuring tool; for thick pipes, thread the fastening strap through the
openings with the smooth side facing inward.
Always secure the measuring tool with both fastening straps and
check the tight seating of the straps. The holding force of the straps
25 depends on the nature of the material that they are being fastened to.
Loosely attached measuring tools can slip down and become damaged
or cause damage.
Do not allow children to use the fastening straps 25 without supervi-
sion. Possible danger of injury through the fastening straps.
Switching the Grade Measurement and Display On and Off
To switch on the grade measurement and display, press the On/Off button 2.
The measuring tool is in grade measurement mode with standard zero point.
To switch off the grade measurement and display, press the On/Off button 2
again.
When no button on the measuring tool is pressed for approx. 30 minutes
and its grade is not changed by more than 1.5°, then the grade measure-
ment and display are automatically switched off to save the battery. This
does not affect the laser.
