1.5. Safety Instructions for the Operating Staff
All cabinets and covers on the iQ-Oval CDS must always be kept
closed. Open cabinets and covers are extremely dangerous as live
electrical components are accessible.
Mechanical or electrical failures must only be repaired by an MHM
authorized/approved technician.
On every occasion, the operator should check the correct
functioning of the safety devices (Emergency STOP, Safety Bars,
Safety Cables), before commencing use of the iQ-Oval CDS.
No modifications to any part of the machine or its assembly system
that may adversely affect safety must be carried out without the
prior approval of MHM.
Program modifications in the control program and changes of
settings which may affect the iQ-Oval CDS’s operation should only
be carried out by an MHM authorized/approved technician.
All working spaces, passageways, escape and emergency routes and
exits must be kept clear.
No tools or other objects must be kept or left in the area of the
machine.
Any modifications or changes to the iQ-Oval CDS’s settings should
only be carried out by an MHM authorized/approved technician.
Always wear protective gloves and safety goggles during cleaning
work, in particular when using solvents!
Any remains of potentially harmful substances should be disposed
of according to the legal requirements of the country or state in
which the iQ-Oval CDS is operated.
All accessories for service and maintenance work (e.g. cleaning
agents) must be collected in suitable containers and disposed of
according to any relevant regulations.
1.6. Personal Protective Equipment
Personal protective equipment must be used at work. This equipment comprises
close-fitting working clothes with tight sleeves and high tearing resistance without any
protruding parts. These features prevent operators from getting caught by moving
machine parts.

4. Transportation and packaging
This section provides an overview of the proper transportation of the iQ-Oval CDS.
4.1. General Notes with Regard to Transportation and Danger Warnings
4.2. Packaging
The iQ-Oval CDS will be packed and delivered in several wooden crates. The crates’
exact number, weight and dimensions will vary slightly according to each model/type
of machine. Contact customer service for more information about individual orders.
4.3. Unloading of the crates
The iQ-Oval CDS is to be unloaded by the customer. A forklift truck with adequate fork
length and lifting capacity (see 4.2 Packaging) will be required.
Upon delivery of the iQ-Oval CDS the consignment must be examined
for external damage immediately. In the case of any damages, they
must be documented and reported to Machines Highest Mechatronic
GmbH within 24 hours.
Danger of falling objects!
The following instructions must be observed
1. Never stand or walk under hanging loads!
2. Transportation must be carried out by qualified staff observing all
safety instructions.
3. The iQ-Oval CDS must only be lifted at the dedicated lifting points.
4. Only the lifting/handling devices and equipment indicated in this
document must be used for the movement of the iQ-Oval CDS.
Non-compliance may lead to serious damage of the iQ-Oval CDS
and result in cancellation of the warranty.
Danger of mechanical damage!
The iQ-Oval CDS must be lifted carefully and only at the dedicated
lifting points at the middle of the base unit. Lifting the iQ-Oval CDS
at/by any other point, especially the tables, may result in serious
damage. Be sure to maintain an adequate and safe distance during
lifting.

Operating instructions iQ-Oval CDS V1-4.docx page 15 of 66
4.4. Packaging material
After unpacking the machine, the packaging material must be disposed of according
to local regulations.
5. Assembly
This section describes the external supply/connection ports of the iQ-Oval CDS and the
points to be observed during assembly.
5.1. General Assembly Instructions
The customer should have a minimum of two persons available to assist the technician
with the installation and assembly of the machine.
5.2. Positioning of the iQ-Oval CDS
The machine must be mounted on a bed with sufficient load-bearing capacity. In case
of doubt this capacity has to be examined by a structural engineer.
In order to guarantee perfect installation and smooth operation of the iQ-Oval CDS,
the machine must be installed at a sufficient distance from adjacent elements of the
building (walls, columns, etc.) and/or other machines. The distance required in each
case depends on the screen size and must be chosen so as to allow the operator to
replace the screens without any problems. The dimensions of the respective machine
are indicated in Chapter 3 Data.
The iQ-Oval CDS must only be installed / assembled by an authorized
MHM service technician or by an authorized service technician from
an official MHM dealer/agent. Any assembly/installation by any third
party not listed above will result in immediate cancellation of the
warranty.

Operating instructions iQ-Oval CDS V1-4.docx page 16 of 66
5.3. Ambient Conditions
For the electrical equipment on the iQ-Oval CDS, ambient conditions according to
standard IEC 60204 “Electrical Equipment of Industrial Machines” should be observed.
The following points should be observed in order to achieve efficient running and an
optimum level of production with the iQ-Oval CDS:
1. The premises, where the iQ-Oval CDS is to be operated, must be kept clean, dry
and well-aired.
2. The ambient temperature must not fall below +5° C or exceed +45° C.
3. Relative air humidity must not exceed 80 %.
4. The mains supply must not exceed or fall below a tolerance of +/- 5 % of the
required voltage for the iQ-Oval CDS. If this voltage stability cannot be
guaranteed, the customer must install a constant-voltage regulator to protect the
iQ-Oval CDS against such fluctuations.
5. The compressed air must be clean, filtered and dry (class 1:4:1 according
ISO8573-1:2010).
6. Compressed air supply must be sufficient in terms of pressure, volume and
consistency.
7. Electricity supply should be sufficient with adequate fuse protection.
8. Maximum installation altitude is 2000m above sea level.
5.4. External supply/Connection ports
Connections for compressed air and mains electricity are located on the base unit of
the iQ-Oval CDS as standard. Overhead supply connections may be ordered optionally
but only at time of order, to enable supplies to enter the machine from above.
Danger of tripping over!
In case of laying supply lines on the floor, it is necessary to attach
step covers.

Risk of electric shock!
Please observe the general safety regulations for electrical
connections when connecting the mains supply to the iQ-Oval CDS.
Avoid any contact with live components.
All flash cure units must be supplied through a
separate/independent connection. Please observe the precise
technical data from the flash cure unit specification sheet.

Operating instructions iQ-Oval CDS V1-4.docx page 18 of 66
6. Commissioning the iQ-Oval CDS
After the initial start-up of the machine, commissioning is to be completed in the
presence of the authorized technician along with any persons authorized on the part
of the customer. During this initial start-up and commissioning, all tasks carried out by
the MHM service engineer or the technicians of an authorized dealer are recorded.
This installation/job sheet must be clearly signed by both parties, stating the date and
location of the iQ-Oval CDS and will be legally binding hereon after.
Initial start-up of the iQ-Oval CDS should only be carried out by an
authorised MHM service engineer or by an approved technician from
an official MHM dealer/agent.
Any defects or complaints must be brought to the attention of the
authorized technician, documented in writing and recorded
immediately on the service technician’s installation/job sheet.
Before starting the machine, mains connection and compressed-air
supply must be checked and, if necessary, established according to
the instructions.

Operating instructions iQ-Oval CDS V1-4.docx page 19 of 66
7. Design and Operation
This section describes design and operation and indicates the individual assemblies.
7.1. General Process Description
The operator applies a substrate (usually a T-shirt) to the pallets at the locating
surface. The substrate will be fixed in position by means of the spray adhesive applied
to the pallets beforehand. Subsequently, the machine moves the substrate to the first
print station, where the substrate is printed by means of screen printing or treated
with optional accessories. Subsequently, the substrate moves to the second station,
where it is treated again, before the process continues with all other stations. Finally,
the substrate arrives at the unloading point, where an operator takes it from the
machine for further processing.
