GENERAL SAFETY
WARNINGS FOR YOUR
LASER MEASURING
TOOL
WARNING: Read all safety
warnings and all instructions.
Failure to follow the warnings and
instructions may result in serious injury.
Save all warnings and instructions for
future reference.
These lasers do not normally present an optical
hazard although staring at the beam may cause
flash blindness.
Do not stare directly at the laser beam. A hazard
may exist if you deliberately stare into the beam,
please observe all safety rules as follows:
1. Laser radiation, do not stare into beam.
2. The laser shall be used and maintained
in accordance with the manufacturer’s
instructions.
3. Never aim the beam at any person or an object
other than the work piece.
4. The laser beam shall not be deliberately aimed
at another person and shall be prevented from
being directed towards the eye of a person for
longer than 0.25 seconds area.
5. Always ensure the laser beam is aimed at a
sturdy work piece without reflective surfaces,
e.g. wood or rough-coated surfaces are
acceptable. Bright shiny reflective sheet steel or
similar is not suitable for laser applications as
the reflective surface may direct the laser beam
back at the operator.
6. Do not change the laser device with a different
type. The manufacturer or an authorized agent
must carry out repairs.
7. CAUTION: Use of controls or adjustments
other than those specified herein may result in
hazardous radiation exposure.
8. Do not use this product in flammable, explosive,
corrosive environments or near medical
equipment or aircraft.
BATTERY WARNINGS
WARNING
1. Use the recommended type of dry battery,
different type of batteries may cause damage.
Do not expose the battery to an overheating
environment, such as sunlight or fire, which
may explode, cause fire or personal injury.
Do not short-circuit or disassemble the battery,
which may explode, cause fire or personal
injury.
The battery may leak if the device is not
used properly. In case of battery leakage,
carefully remove the liquid with a cloth. Once
contact battery liquid, wash with running
water immediately, and seek medical help
immediately if liquid splashes into eyes.
Do not charge for batteries that are not suitable
for recharging.
Keep the battery away from children because of
the risk of swallowing.
Children are not allowed to use the tool, which is
not a toy.
Remove the batteries to prevent battery leakage
if you do not intend to use the tool for a long
time.

ASSEMBLY
INSERTING/REPLACING THE
BATTERIES
Using alkali-manganese or rechargeable
batteries is recommended for operation of the
measuring tool.
To open the battery lid 5 , press the latch 4 in the
direction of the arrow and remove the battery lid.
Insert the batteries/rechargeable batteries. When
inserting, pay attention to the correct polarity
according to the representation on the inside of
the battery compartment.
Always replace all batteries/rechargeable
batteries at the same time. Do not use different
brands or types of batteries/rechargeable
batteries together.
• Remove the batteries/rechargeable batteries
from the measuring tool when not using it for
longer periods. When storing for longer periods,
the batteries/rechargeable batteries can corrode
and self-discharge.
OPERATION
INITIAL OPERATION
•
Do not leave the switched-on measuring tool
unattended and switch the measuring tool off
after use. Other persons could be blinded by the
laser beam.
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
longer periods. In case of large variations in
temperature, allow the measuring tool to adjust
to the ambient temperature before putting it into
operation.
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 each time before
continuing to work.

WORKING ADVICE
General Information
The reception lens 7 and the laser beam
outlet 6 must not be covered when taking a
measurement.
The measuring tool must not be moved while
taking a measurement (with the exception of the
continuous measurement function). Therefore,
place the measuring tool, as far as this is
possible, against or on the measuring points.
Measurement takes place at the centre of the
laser beam, even when target surfaces are
sighted at an incline.
INFLUENCE EFFECTS ON THE
MEASURING RANGE
The measuring range depends upon the light
conditions and the reflection properties of the
target surface. For improved visibility of the
laser beam when working outdoors and when
the sunlight is intense, use the laser viewing
glasses(not supplied) and the laser target plate
(not supplied), or shade off the target surface.
INFLUENCE EFFECTS ON THE
MEASURING RESULT
Due to physical effects, faulty measurements
cannot be excluded when measuring on
different surfaces. Included here are:
– transparent surfaces (e.g., glass, water),
– reflecting surfaces (e.g., polished metal,
glass),– porous surfaces (e.g. insulation
materials),
– structured surfaces (e.g., roughcast,
naturalstone).
If required, use the laser target plate (not
supplied) on these surfaces.
Also, air layers with varying temperatures or
indirectly received reflections can affect the
measured value.
