1. GENERAL INFORMATION
1.1 Purpose of use
The Cut-True 29H Guillotine Cutter is designed to cut paper and cardboard. It is mainly used by
printing houses, print finishing specialists, copy shops and offices.
The machine must be used according to operator manual and conditions as assemble,
disassemble, reassemble, installation, controlling and maintenance should be respected.
1.2 Documentation
 This operator manual is provided with the machine
 The manual should be always stored near the machine
 Operators should be familiar with the manual before starting to use the machine.
2. SAFETY
The cutter is designed with a variety of safety features. Operators should not make any alterations
to these features, which could cause personal injury, equipment damage, and invalidate the
manufacturer’s warranty. This requirement is also applicable to the spare parts used during the
repairs.
Any repairs should be made only by authorized technicians trained by the manufacturer. Repairs
made by unauthorized technician(s) will invalidate the warranty given by manufacturer, and
manufacturer is no longer responsible for any damages.
 Warranty is terminated if the machine is modified by user without permission of
manufacturer
 Modification by user removes all responsibility from the manufacturer for any
damages
Despite all precautions, untrained operators may cause the risk of injury or damage.
Possible effects of incorrect usage:
 risk of life
 risk of body damage
 risk of machine damage
 risk of deterioration of technical condition of machine

Page 5/ 62
2.1 Symbols: meaning and application
Table 1. Symbols meaning
 Read operator manual
 Respect operator manual
 INFORMATION
 WARNING!
 Risk of machine damage
 CAUTION! DANGER!
 Danger to life
 Danger of bodily harm
 Dangerous electrical voltage!
 Children must not operate the device!
 Do not put hands underneath the knife!
 Do not leave knives unattended
 Do not remove or transport knives without covers!
 Risk of injury!
• Do not cut hard materials or materials, which may be splintered

Page 6/ 62
2.2 Operator qualifications
 The cutter can only be operated by qualified staff who have been properly trained.
 The cutter should be used only by trained adults, and not by children.
INFO
Before operating the cutter the operator must read the operating instructions.
2.3 Requirements for the operator's workplace.
The cutter should be located on a dry, stable surface to reduce the chance of the operator slipping
or falling. Power cables should also be routed to avoid a trip hazard.
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)
 Ambient air temperature: + 5 ° C - + 30 ° C

Page 7/ 62
2.4 Avoiding risks when operating the cutter
DANGER!
Operator must only use 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 (e.g. safety light curtains, two-handed
controls) creates a danger to life or injury!
2.5 Possible risks of operation and evaluation of residual risk
The Cut-True 29H is manufactured to the highest standards for use, and operator safety. Risks
remain, due to the failure of operator to follow proper use instructions.
 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
 Allowing unauthorized persons, especially children, to use the cutter
 Unauthorized machine alterations
 Cleaning and lubrication of the cutter during operation
 Working 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
2.6 Safety systems used in the cutter
• Two-handed operation buttons – blade is engaged using a two-handed start system, which
keeps operator’s hands out of the cutting area
• LED Safety Curtain – cutter will not operate if the safety curtain is not functioning
