Preface to the operating manual
Preface This operating manual is designed to make it easy to familiarise yourself
with the machine and use it for its intended purpose.
The operating manual contains important information on how to operate
the machine safely, properly and economically. Compliance with it will
help to avoid dangers, repair costs and downtimes and increase the
reliability and service life of the machine.
The operating manual must be supplemented with instructions based on
current national regulations for accident prevention and environmental
protection.
The operating manual must be available at the location of the machine at
all times.
The operating manual must be read and used by everybody who
undertakes work on the machine, for example:
Operation, including setting, troubleshooting whilst operating,
removal of production waste, care, disposal of media and
consumables
Maintenance (servicing, inspection and repair) and/or
Transport
In addition to the operating manual and the binding regulations for accident
prevention which apply in the user’s country and at the place of use, the
acknowledged technical rules for safe and correct working practice must als
be observed.
Required tool
A tool in the form of a saw blade is needed to operate the stone cutting
saw. These tools can be purchased from the manufacturer.

1.1.3 Saw blades
1.7.1
Use the special LISSMAC diamond saw blade for dry cuts on the
masonry saw only.
A sales list of saw blades can be requested from LISSMAC.
Do not cut with toothed saw blades.
The saw blades require a statement of direction of rotation.
Saw blade diameter, saw blade speed and mounting diameter need to
be matched to the machine (see section 2.3).
Do not use damaged saw blades
1.2 Principle of intended use
1.2.1 The masonry saw is exclusively designed for the dry cutting of large-sized
building blocks made of mineral materials. Use only building blocks that are
not suitable for cutting in wet process.
Please note that Poroton and vertical coring bricks can differ from the
composition and the bulk density (hardness), depending on the
manufacturer. The wear on the saw blade is too heavy with the use of hard
Poroton and vertical coring bricks and is therefore not recommended.
The operation of the masonry saw is only permitted with the use of a
corresponding dust extraction system. The dust extraction system used for
cutting the building blocks must also be permitted.
The cutting of wood, metal, plastics or other types of stone is not
allowed!
The manufacturer/supplier cannot accept any liability for damage caused by
unintended use.
Intended use also includes compliance with the operating manual and
compliance with the inspection and maintenance requirements.
1.2.2
The machine must only be used if it is in technically perfect condition and for its
intended use, with an awareness of safety and potential dangers and as set out
in
the operating manual! In particular, faults which may adversely affect its safety
must be rectified immediately.
1.2.3
This masonry saw is only safe
if it is used with saw blades, designed for this machine
(see 1.1.3 and 2.3).
7/28
1.3 Organisational action
1.3.1
Always keep the operating manual at hand at the location of the machine!
1.3.2
Supplements to the operating manual include general statutory and other
binding regulations for preventing accidents and protecting the environment

These duties may also relate, for example, to handling hazardous
substances or wearing personal protective equipment or road traffic
regulations.
1.3.3 The personnel entrusted with the work must have read the operating manual,
particularly the section entitled “Safety information” before starting work. It is
too late to do so during work. This particularly applies to personnel who only
work on the machine occasionally, for example setting and maintenance
personnel.
1.3.4

condition (see section 1.1.2)!
1.3.8
In the event of any safety-relevant changes to the machine or the way in which
is operating, shut down the machine immediately and report any fault to the
relevant department/person!
1.3.9
Do not carry out any modifications, additions or conversions to the machine
without the consent of the supplier!
