• Never point the laser beam towards reflecting sur-
faces and persons or animals. Even a laser beam
with a low output can cause damage to the eyes.
CAUTION
Methods other than those specified here
can result in dangerous radiation exposure.
• Never open the laser module. Unexpected expo-
sure to the beam can occur.
• If the product is not used for an extended period of
time, the batteries should be removed.
• The laser may not be replaced with a different type
of laser.
• Repairs of the laser may only be carried out by the
laser manufacturer or an authorised representative.

Safety instructions for handling
batteries
• Always make sure that the batteries are inserted
with the correct polarity (+ and –), as indicated on
the battery.
• Do not short-circuit batteries.
• Do not charge non-rechargeable batteries.
• Do not overcharge batteries!
• Do not mix old and new batteries or batteries of dif-
ferent types or manufacturers! Replace an entire set
of batteries at the same time.
• Immediately remove used batteries from the device
and dispose of them properly! Do not throw batter-
ies away with household waste. Defective or used
batteries must be recycled in accordance with Di-
rective 2006/66/EC. Return batteries and / or the
device via the collection facilities provided. You can
find out about disposal options from your local or
municipal authority.
• Do not allow batteries to heat up!
• Do not weld or solder directly on batteries!
• Do not disassemble the batteries!
• Do not allow batteries to deform!
• Do not throw batteries into fire!
• Keep batteries out of the reach of children.
• Do not allow children to replace batteries without
supervision!
• Do not store batteries near fire, ovens or other
sources of heat. Do not use batteries in direct sun-
light or store them in vehicles in hot weather.
• Keep unused batteries in the original packaging and
keep them away from metal objects. Do not mix un-
packed batteries or toss them together!
This can lead to a short circuit of the battery and
thus damage, burns or even the risk of fire.
• Remove batteries from the device when it will not
be used for an extended period of time, unless it is
for emergencies!
• NEVER handle batteries that have leaked without
appropriate protection. If the leaked fluid comes into
contact with your skin, the skin in this area should
be rinsed off under running water immediately. Al-
ways prevent the fluid from coming into contact with
the eyes and mouth. In the event of contact, please
seek immediate medical attention.
• Clean the battery contacts and corresponding con-
tacts in the device prior to inserting the batteries.
Safe work
Tools may only be used by trained and experienced
persons who are proficient in handling tools.
• The maximum speed specified on the insertion tool
may not be exceeded. Where indicated, the speed
range must be observed.
• Circular saw blades with cracks in the blade must
be discarded (repair is not permitted).
• Tools with visible cracks must not be used.
• Tools must be cleaned regularly.
• Tool parts made of light alloys may only be cleaned,
e.g. of resin, with solvents that do not impair the
mechanical properties of these materials.
1. Tools and tool bodies must be clamped in such a
way that they cannot come loose during operation.
2. Extending the key or tightening it with the help of
hammer blows is not permitted.
3. The clamping surfaces must be cleaned of dirt,
grease, oil and water.
4. Spare parts must comply with the specifications for
original parts supplied by the manufacturer.
5. Maintenance work and modifications to circular saw
blades should only be carried out by a competent
person, i.e. a person with specialist training and ex-
perience who is familiar with the requirements for
construction and design and who is familiar with the
required safety levels.
Residual risks
The product has been built according to state-of-
