Introduction
This manual was conceived at the manufacturer and is an indivisible part of the delivery
enclosed with the machine. It contains basic information for qualified operating staff and
describes the surroundings and using ways of the machine for those it is intented.
It contains also all necessary information for a correct and safe operating.
The machine is equipped with various safety equipment protecting operator and machine
as well at usual technological using. These regulations, however, cannot sheet all other
safety aspects. That is why operator must peruse and make sense of this manual before
starting of machine use. Installation and operation mistakes will be foreclosed herewith.
Do not try to start the machine before having read all instructions manual
delivered with the machine and understood every function and technique.
Some information or drawings need not be intended especially for by yours bought type,
for this manual contains all information of other this type variants we produce. By comparing
of competent manual part with your machine – you will learn whether they correspond.
The producer reserves himself the right for particular variants in frames of a fluent technical
development of the machine.
To better stress the importance of some basic passages, they are printed in heavy letters
and marked by some preceding symbols - Appeal recommending to follow entirely following
regulation:
Appeal recommending to act entirely according to following
safety regulation. Disobservance of this regulation can be
very dangerous and cause a killing or grave health exposure
of operating personnel.
Warning from improper techniques or way of machine use
that can endanger human health, machine functions,
enviromnent or cause economic loss. Breach of these
regulation may cause a killing or a grave health exposure of
the operator
Caution is an appeal to a due care for practising following
operations. Non-performing of this caution may cause
a human injury or damage at the machine.
Regard the instructions explicit on shields herewith the machine is equipped. In case of its
damage contact the producer and renew the shield in any way.
Caution
The text and pictures of the manual is a know how of the ROJEK Co. No part of it can be
copied and third persons are not allowed to learn it or its part without company´s approval.

1.0 Machine use
This machine is designed as a dimension circular saw with hand shifting of workpiece.
The sliding table fays to the saw blade with a scorer. The saw blade is adjustable in height
and with tilting. The machine is intended above all to larger cabinet making workshops for
accurate sawing of wood and laminboards from wood and those on wood based ones
with a maximal sawing width of 1050 mm (800; 1 500 mm).
The machine is intended to be operated only by one single person.
Any manipulating with the machine by children or youth is forbidden !
1.1 Qualification of workers
Only a man or woman trained in woodworking branche or instructed and schooled by such
a specialist can operate the machine. Machine operator is obliged to learn this manual
and abide with all safety regulations, rules and appointments, valid in a country in question.
1.2 Working surroundings
The machine must operate in workshop surroundings of temperature range + 5°C - + 40°C,
relative air humidity 30% - 95% non condensing and altitude 1000 m above the sea in sur-
rounding classified : fire danger of combustive dusts (BE2N2).
2.0 Machine signification
Machine type can be identified at the production

Above stated values are those of emissions and need not represent the safe working
values. Although there exists a correlation between emissions values and levels of
exposition, these values cannot be used for a reliable statement whether other precautions
are necessary or not. Agents, influencing a real exposure of workers, include other working
space attributes, other sources of nois, etc., e.g. the number of machines and other from
neighbourhood influencing processes. The most permissible exposition levels can differ
according to country in question, too. This information will serve for machine user to a better
astimation of risks.
