Welcome
Congratulations on your purchase of the new cutter!
The SummaCut cutters are made for sign makers, demanding only the very best cutting
quality.
SummaCut is Summa’s most popular and affordable line of vinyl cutters. Their
characteristics and performance match those of the most excellent cutters. They offer
tracking accuracy, speed and features not found in other affordably-priced cutters.
Summa engineers know there’s not a more important vinyl cutter feature than tracking.
That’s why every cutter we build starts with our exclusive and patented MicroSprocket™
grit roller. The unrivalled media tracking system guarantees the highest precision on
cuts up to 8 meters long. So, there’s no need to monitor whilst the machine performs a
cutting job, not even during long cutting jobs.
SummaCut now offers the unmatched Optical POSitioning Sensor OPOS X. The
automated contour alignment system OPOS stands for OPtical POSitioning System.
The OPOS X sensor technology senses marks on a wide range of materials. Some of
our latest features include a fully automated workflow with barcode reading, enabling
you to contour-cut multiple jobs without any user intervention. Another feature is while
using multiple sheets with repeating graphics, the OPOS sensor will start looking for
marks immediately after a new sheet is loaded.
This manual is a reference guide for installing and operating the SummaCut Series
cutters.
Minimum revisions needed for this manual:

1.3.1.3
Safety precautions
WARNING: The SummaCut cutters use razor-sharp knives. Touching the
knife with bare hands may cause injury. Do not touch the knives while the
machine is cutting.
The entire base plate should be considered as a dangerous area when the cutter is
switched on and off. The tool carriage can move from the left to the right and the
yellow media sleeves are sharp and can grab loose objects, clothing or body parts.
The cutter constantly measures the current through the motors. If the machine detects
the current is too high, then the current will be cut off to the motors and a fatal error
message will be displayed on the control panel.
Make sure to observe all the caution labels on the cutter.
1.3.2
Operating environment
Environmental conditions can significantly affect the machine’s performance.
The environmental conditions of the machine (without media) are as follows:
Operating Temperature
15 to 35°C
59 to 95°F
Storage temperature
-30 to 70°C
-22 to 158°F
Relative humidity
35 - 75 %, non-condensing
35 - 75 %, non-condensing
It is possible that the environmental conditions of the used media are stricter than
those of the machine itself. Please refer to the documentation about the used media.
Moreover, make sure that the media has had enough time to acclimatize.
NOTE: Keep the cutter away from direct sunlight or a strong indoor light
source. The optical sensors in the machine may be affected, thus causing
unexpected behaviour of the cutter.
WARNING: There is a risk of injury from being caught or trapped in moving
machine parts.
Keep hands, hair, clothing and jewellery away from moving parts. Do not
wear jewellery, loose clothing, scarves, open jackets or shirtsleeves.

WARNING: Before changing the fuse, make sure that the cutter is
completely disconnected from its power source.
WARNING: For continued protection against risk of fire, replace only with
the same type and rating of fuse.
Fuse Rate: T2.0A, 250V SCHURTER SPT OR EQUIVALENT.
The power supply detects the line voltage and switches automatically between 110V
and 230V.
WARNING: An insulated ground conductor must be installed as part of the
branch circuit that supplies power to the wall outlet, connected to the cutter.
The ground conductor must have the same size, insulation material and
thickness as the grounded and ungrounded branch-circuit-supply-
conductors, but the insulating seat should be green or green with yellow
striping.
The ground conductor described above must be grounded at the electrical
distribution board or, if power is supplied by a separate system, at the power
supply transformer/motor generator set.
The wall sockets, into which the cutter is plugged-
in, must be of the
grounded type. The grounded conductors, serving the wall socket, must be
properly connected to the ground.
For emergency access, the cutter should be installed near the socket-outlet
for easy access.
