Additional safety instructions for laser light
The laser light and laser radiation used in this system
comply with class 1 and a maximum performance of 390
μW and 650 nm wave length. Normally laser does not
represent an optical danger, although staring into the
beam can cause ash blinding.
Warning: Do not look directly into the laser beam, since
this could represent a risk. Please observe the following
safety instructions:
• The laser may only be used and maintained in accord-
ance with the instructions of the manufacturer.
• Only point the beam onto the work piece, and never
at a person or another object.
• The laser beam must not deliberately be pointed at
persons. It must not be pointed into the eyes of a per-
son for more than 0.25 seconds.
• Always make sure that the laser beam is directed onto
a robust work piece without a reecting surface. That
means that timber and materials with a rough surface
are acceptable. Shiny, reecting plates or similar ma-
terials are not suitable for laser, since the reecting
surface could return the beam to the operator.
• Do not exchange the laser light unit for another type.
Repairs have to be conducted by the manufacturer or
an authorised specialised company.
Caution: You must only apply the regulation and adjust-
ment tools and methods described in this manual. Non-
observance can lead to dangerous radiation.

can be easily transported even by one person. It is suf-
cient to lift the saw by the handle after the locking button
(13) has been locked in the lowest position.
TRANSPORT
In case the machine needs to be transported put it in the
original packing in which it was delivered. See to it that
it is placed in the correct position (regard signs on box).
If possible secure the box with straps to avoid unintend-
ed movement or loss of parts of the machine.
POSITION/WORK STATION
Place the machine on a work bench or on a sufciently
at base/pedestal to ensure the best possible stability.

surface or the upper work surface is between 90 and 95
cm. from the ground.
Always ensure that there is at least 80 cm. of manoeu-
vring space in all directions around the machine in or-
der to perform all necessary cleaning, maintenance and
adjust ment operations safely with a sufcient amount of
space available.
CAUTION: Ensure the machine is placed in a suitable
position both in terms of environmental conditions and
lighting.
Always bear in mind that general environmental condi-
tions are of fundamental importance to prevent acci-
dents.
ELECTRICAL CONNECTIONS
Check that the electrical system to which the machine is
connected is earthed in compliance with current safety
regulations and that the current socket is in perfect con-
dition.
The electrical system must be tted with a magnetother-
mal protective device to safeguard all conductors from
short circuits and overload.
The selection of this device should be in line with the fol-
lowing electrical specications of the machine stated on
the motor.
NOTE: Your mitre-saw’s electrical system is equipped
with an undervoltage relay which automatically opens
the circuit when the voltage falls below a minimum pre-
established limit and which prevents the self-reset of ma-
chine functions when voltage returns to normal levels.
If the machine stops involutarily, do not be allarmed.
Make sure that there has not been a voltage failure in the
electrical system.
ADJUSTING
ATTENTION: All the adjustment procedures illustrated
