1.4 Introduction
In this manual there are included information about safety features of the guillotine.
The manual should be stored near the machine and secured from lost or damage. It is
necessary to operate the machine according to manual but also to local, general rules of
safety. The employee is also obliged to train respectively the the operators of the machine
according to the manual. Each operator should confirm receiving of the manual and sign the
obligation to respect it. The requirement is necessary to start working on the machine.
2. SAFE OPERATION
The elements of mechanics, electronics of the guillotine are made according to latest
solutions and general rules of technology to secure the operator in case of failure. The
adequate level of safety elements ensure operator safety. It is necessary to check with
manufacturer if user wants to use special, extra equipment which was not installed and
delivered by manufacturer. Otherwise the factory warranty is no longer valid and
manufacturer takes no responsibility for modifications done in the machine and damages
cause by such.
This requirement is also applicable to the spare parts used during the repairs!
The repairs should be made only by servicemen who were trained by the manufacturer. In
case of the repairs done by unauthorized service the warranty given by manufacturer is not
valid and manufacturer is no longer responsible for any damages.
 Warranty is terminated if the machine is modified by user without any
permission of manufacturer
 Modification by user removes all responsibility from the manufacturer for any
damages

9
Despite all precautions the operating of the machine by not trained staff or wrongly trained
can cause the risk of damage.
Each person present during the installation, maintenance and usage of the machine must be
familiar with the manual, especially the chapter Safety of use.
Despite the obligation to do it prior using the machine such means should be also repeated!
Possible effects of incorrect usage:
 risk of injury
 risk of machine damage
 risk of deterioration of technical condition of machine

2.2 Employee qualifications
 The guillotine cutter can only be operated by qualified employees who have been
properly trained by the cutter manufacturer. With regard to safety rules, in the
contents of this instruction, by a qualified employee should be understood as a
person authorized to set machines, circuits and electrical circuits in accordance with
the standards of security technology.
 The guillotine cutter should only be operated by employees trained and authorized for
this purpose by the employer. Such employees must be of legal age.
 An operator who does not use the language of the available version of the user
manual in speaking or writing, should be fully instructed in verbal instructions and
complete comprehensive and practical training to familiarize with the content of the
document.
This requirement is especially important for chapter "Safety of use".
The manufacturer recommends that the operator be given the translation of "Safety of
use" in his mother language with confirmation of receipt of such a document.

11
INFO
Before operating the cutter the operator must read the operating instructions.
 Every employee delegated to work during assembly, disassembly, reassembly,
commissioning, servicing and maintenance (technical inspection, servicing, repairs) of
the cutter must read the entire operating manual, in particular the chapter "Safety of
use".
 The manufacturer recommends that the buyer of the machine, transferring it for use,
obtained a written confirmation of the contents of the instructions.

2.3 Requirements for the operator's workplace.
The user is obliged to create working conditions at the cutter workplace that
preclude the operator from slipping, slipping or falling due to poor ground conditions,
the way of routing the wires or the lack of convenient access!
2.3.1 Personal protection equipment
If necessary or if it results from the regulations in force, use the following personal protective
equipment:
 Wear safety shoes
 Wear safety goggles - eg when cutting fragile material
 Use hearing protection - eg when cutting hard material
2.3.2 Permissible environmental and operational conditions
 Operation of the machine is permitted in closed rooms
 Humidity: 35% - 95% (non-condensed)

12
 Ambient air temperature: + 5 ° C - + 30 ° C
2.4 Expected risks when operating the cutter
Using the single cutter as intended, you can predict some of the risks to your life and
health. To avoid existing hazards, the rules of using and operating the cutter must be
explained in detail. Special attention should be paid to the cutter units and situations
posing a threat to the operator and third parties:
DANGER!
The operator can operate the machine in good technical condition.
At the beginning of each work shift and after each knife replacement, check the operation of
the safety devices. Interference in security or bypassing them (eg safety light curtains, two-
handed controls) creates a danger to life or injury!
At the moment, the cutter can only support one operator!
The operator himself must also make sure that the machine is not operated by unauthorized
persons!

2.5 Description and evaluation of residual risk
The Grafmasz company takes responsibility for the construction of the cutter in order
to eliminate the danger, although some risk elements during the cutting machine operation
are possible. Residual risk resulting from incorrect behavior of the cutter operator.
 Failure to follow the safety rules described in the operating instructions
 Using the cutter for other purposes than those described in the user's manual
 Staying unauthorized persons, especially children, when cutting on the
machine
 Unauthorized making any alterations
 Cleaning and lubrication of the cutter during operation
 Work with dismantled or defective covers
 Manipulation within the drive units and moving parts of the cutter during
operation
 Checking the cutter's technical condition and performing servicing or repairs
with the cutting machine
 Checking transmission gears during operation
When presenting the residual risk, the cutter is treated as a device that was
designed and manufactured according to the state of the art in the year of its
manufacture.
Residual risk assessment

14
When following such recommendations as:

system
 Non-contact protection device - an optoelectronic device that creates a safety
curtain
 Cam device - a device that controls the knife stop in the upper position.
