WARNING
When using Goliath basic safety precautions should
always be followed to reduce the risk of fire, electric shock
and personal injury including the following.
Read all these instructions to operate this product and
save these instructions for future reference.
Working area safety rules
●Keep the working area clean and well lit. Cluttered or
dark areas invite accidents.
●All work areas must be free of objects that obstruct the view
of observation
●Do not operate Goliath in explosive environments. Keep
children and bystanders away while operating Goliath.
Distractions can cause you to lose control of the machine.
Electrical safety
●Goliath plugs must match the outlet. Never modify the
plug in any way. Do not use any grounded adapter
plugs with Goliath. Unmodified plugs and matching outlets
will reduce risk of electric shock.
●Avoid body contact with earthed or grounded surfaces,
such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body is
earthed or grounded.
●Do not expose Goliath to rain or wet conditions. Water
entering Goliath will increase the risk of electric shock.
●Do not abuse the cable (44). Never use the cord for
carrying, or unplugging Goliath. Keep cord (44) away
from heat, oil, sharp edges and moving parts. Damaged
or entangled cords increase the risk of electric shock.
●If operating Goliath in a damp location is unavoidable,
use a residual current device (RCD) protected supply.
The use of an RCD reduces the risk of electric shock.
Personal safety
●Stay alert, watch what you are doing and use common
sense when operating Goliath. Do not use Goliath while
you are tired or under the influence of drugs, alcohol or
medication. A moment of inattention while operating
Goliath may result in serious personal injury.
●Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal injuries.
●Prevent unintentional starting. Ensure the switch is in
the off-position before connecting to the power source,
picking up or carrying the tool. To avoid accidents do not
touch the power button and do not connect the machine to
the power supply while carrying Goliath CN.
●Remove any adjusting key before turning the power
tool on. An accessory or a key left attached to a rotating
part of Goliath may result in personal injury.
●Do not overreach. Keep proper footing and balance at
all times. This enables better control of Goliath in
unexpected situations.
●Dress properly. Do not wear loose clothing or jewelry.
Keep your hair and clothing away from moving parts.
Loose clothes, jewelry or long hair can be caught in moving
parts.
●Ensure that dust extraction devices and collection
facilities are connected and properly used. Use of dust
collection can reduce dust-related hazards.
●Do not let familiarity gained from frequent use of tools
allow you to become complacent and ignore tool safety
principles. A careless action can cause severe injury within
a fraction of a second.
Goliath use and care
6 Springa Srl, via Giovanni Durando 38/A, 20158 Milan, Italy Operating manual GOLIATH Ver.01/2020

●Do not overload or forcefully move the machine. Use
only Goliath for your application. The correct tool will do
the job better and safer at the rate for which it was
designed.
●Do not use the Goliath if the switch does not turn it on
and off. Any tool that cannot be controlled with the switch is
dangerous and must be repaired.
●Disconnect the plug from the power source before
making any adjustments, changing accessories, or
storing Goliath. Such preventive safety measures reduce
the risk of starting the machine accidentally.
●Store Goliath out of the reach of children and do not
allow persons unfamiliar with the tool or these
instructions to operate Goliath. Goliath is dangerous in
the hands of untrained users.
●Maintain Goliath and its accessories. Check for
misalignment or binding of moving parts, breakage of
parts and any other condition that may affect the
Goliath ‘s operation. If damaged, have the machine
repaired before use. Many accidents are caused by poorly
maintained tools.
●Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to bind
and are easier to control.
●Use Goliath, accessories and tool bits etc. in
accordance with these instructions, taking into account
the working conditions and the work to be performed.
Use of Goliath for operations different from those intended
could result in a hazardous situation.
●Keep handles and grasping surfaces dry, clean and free
from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpected situations.
Service
●Have your Goliath serviced by a qualified repair person
using only identical and original replacement parts. This
will ensure that the safety of the tool is maintained.
Safety Warnings
●Goliath is intended to cut wood, wood-like or plastic or
lightweight alloys products. It cannot be used with
abrasive cut-off wheels for cutting ferrous, fiberglass or
carbon fiber materials. Abrasive dust causes moving parts
to jam. Sparks from abrasive cutting may burn the
electrospindle protection, the bit and other plastic parts.
●Do not use this saw to cut pieces that are too small.
The workpiece must be stationary. Do not cut
“freehand” in any way. Unrestrained or moving
workpieces could be thrown away at high speed, causing
injury.
●Never cross your hand over the intended line of cutting
either in front or behind Goliath. The proximity of the
spinning saw blade to your hand may not be obvious and
you may be seriously injured.
●Inspect your workpiece before cutting. If the workpiece
is bowed or warped, clamp it. Bent or warped workpieces
can twist or shift and may cause blockage of Goliath while
cutting. There should be no nails or foreign objects in the
workpiece.
●Do not use Goliath until the table is clear of all tools,
wood scraps, etc., except for the workpiece. Small
debris or loose pieces of wood or other objects that contact
the revolving blade can be thrown with high speed.
●Cut only one workpiece at a time. Stacked multiple
workpieces cannot be adequately clamped or braced and
may bind on the blade or shift during cutting.
●Ensure Goliath is mounted or placed on a level, firm
work surface before use. A level and firm work surface
reduces the risk of the machine becoming unstable. Plan
your work. Provide adequate support such as table
extensions, table stands, etc. for a workpiece that is wider
or longer than the table. Workpieces longer or wider than
the table can tip over if not securely supported. If the cutoff
piece or workpiece tips over, it can lift the electrospindle
protection, be thrown by the spinning blade or cause Goliath
to fall.
●Do not use another person as a substitute for a table
extension or as additional support. Unstable support for
the workpiece can cause the tool to block or the workpiece
to shift during the cutting operation pulling you and the
helper into the spinning blade.
●The cut-off piece must not be jammed or pressed by
any means against the spinning bit of Goliath.
●If the cutting process stops, wait for all moving parts to
stop and disconnect the plug from the power source.
Then remove the jammed material. Sawing with a
jammed workpiece could cause loss of control or damage to
Goliath.
●Keep your workplace clean. Blends of materials are
particularly dangerous. Dust from light alloys can burn or
explode.
●Do not use dull, cracked, bent or damaged saw blades.
Unsharpened or improperly set saw blades produce narrow
kerf causing excessive friction, blade binding and kick back.
●Use of blades that do not match the mounting hardware
of the saw will run eccentrically, causing loss of
control.
●Never remove cutting remainders, wood chips, etc.
from the sawing area while the machine is running.
Always put your device to sleep and then switch the
machine off.
●Do not touch the tool after working before it has cooled.
The tool becomes very hot while working. Wait 5 min from
machine stop before touching the spindle or tool.
●Never make warning signs on Goliath unrecognizable or
unreadable.
●Before performing any type of maintenance and/or
adjustment operation on Goliath it is mandatory to
disconnect all sources of power supply. It is mandatory
to ensure that the machine is stationary, and that
unexpected start-up does not occur.

Noise level information
Noise emission values measured in accordance with
EN 62841-3-9.
12 Springa Srl, via Giovanni Durando 38/A, 20158 Milan, Italy Operating manual GOLIATH Ver.01/2020

The estimated sound pressure level A of the machine is dB(A):
noise level 85 dB(A); sound power level 95 dB(A).
Measurement uncertainty K=3 dB.
Always use the acoustic protection.
The noise level indicated in these instructions has been
detected in accordance with a standardised measurement
procedure and can be used for comparison between tools.
The same procedure is also suitable for a temporary evaluation
of noise emission.
The indicated noise level refers to the main uses of the
machine.
However, the noise level may vary if Goliath is used for other
applications, with different accessories or with insufficient
maintenance.
This could significantly increase noise emissions over the entire
operation.
For an accurate evaluation of the noise emission you should
also consider the periods when the tool is switched off or on but
not actually used.
This could significantly reduce noise emission over the entire
operation.
ASSEMBLY AND STARTING-UP
Always ensure that the machine cannot start
unintentionally. The mains plug must never be connected to
the power supply either during assembly operations or during
any type of intervention on Goliath.

Electrical connection
The connection to the electrical network must comply with all
the safety recommendations described in the previous
paragraphs.
Pay particular attention that the available voltage is equivalent
to the one shown on the identification plate located on Goliath
base.
WARNING: Ensure that the power line is properly sized and
that the earthing system is in compliance.
The presumed short-circuit current at the machine
connection point must be less than 10 kA.
Check that the mains voltage matches that of the machine.
Perform the following procedure:
●Place Goliath on the ground above the panel (48) that is to
be worked or above the wasteboard that will support the
processing (49).
●Place the cable support system (43) in the peripheral area
of the martyr panel (49) (this area cannot be used for the
operation).
●Screw in and lock the cable support system (43) to the
martyr panel (48) using the 4 screws provided (52) (a
thickness of not less than 15 mm is recommended for the
martyr panel)
●Extend completely the cable support system and lock it
through the specific ring.

●Connect the female connector at the end of the coiled cable
(44) to the male connector (28) present on Goliath and
make sure it is locked.
●Power Goliath by inserting the power connector of the
coiled cable into a power outlet.
●Turn on Goliath power switch (27)
Fixing of the position tower sensor
WARNING - Instructions for correct use of measuring tower
sensors x avoid damage to the winding system.
The measuring tower sensors have a spring-loaded winding
system and an internal encoder that ensure the positioning
accuracy of Goliath.
Rapid cable rewinding if not guided by the user could
damage the winding system, the positioning accuracy of
Goliath, and in extreme cases damage the measuring
tower sensors making it unusable.
When using the turrets, especially in 'panel detection'
operations with the encoder hook (35) connected to Goliath,
the encoder cable (36) should ALWAYS remain as
horizontal as possible to avoid unexpected detachment of
the encoder hook (35) and uncontrolled rapid rewinding.
ALWAYS MAKE SURE that the encoder hook (35) attachment
is correct before extending the encoder cable (36).
NEVER ROLL free rewind the measuring tower sensors
encoder cable (36).
The anchoring of the tower sensors to the worktable takes
place during the 'Panel Detection' procedure.
The tower sensors shall be fixed to two adjacent vertices (not
on the same diagonal) of the panel to be milled (48).
WARNING: The tower sensors can be attached only after the
panel position and size of the panel to be worked definition
procedure (Panel Detection) has been completed.
14 Springa Srl, via Giovanni Durando 38/A, 20158 Milan, Italy Operating manual GOLIATH Ver.01/2020

Consider the best tower sensors positions in relation to the
shape and size of the martyr panel.
To obtain the best from the measurement system, prefer the
corners that include one of the short sides of the panel to be
worked.
Use the self-tapping screws (51) provided with Goliath kit to fix
the tower sensors.
Pay attention to the mounting direction: the USB connector
(40) to charge the tower sensors must face outwards the panel.
(See Table 06)
Make sure that the tower sensors base adheres correctly to the
support plate and that the fastening prevents free movement of
the tower sensors top.

the panel extensions when indicated by the software.
(Please note: two sides must be selected and must
necessarily be adjacent to each other.) It is not
recommended to select the side between the 2 tower
sensors.
NOTE: Panel extensions must be made of panels with the
same thickness as the one being processed. The extensions
allow us to optimize the working area.
During the operation, the operator must remain outside the
working area identified by the panel detection procedure.
Part Program creation and transmission to Goliath
The design chosen for the production can be set before or after
the panel detection procedure.
Performing the design after the panel detection ensures that it
can be completely contained in the work surface.
As shown in Fig. 5, you can draw directly on the panel or import
a project in a pre-existing svg format (Fig. 3). For more
information about the import of projects see the dedicated
paragraph.
In the window (Fig.7-10) that shows the dimensions L and H of
the panel, enter the thickness Z too.
NOTE: indicating a panel thickness different from the one that
will be cut, may result in the unsuccessful execution of the cut
and in extreme cases also the projection of machined parts of
the panel.
Once the path is selected, a side panel appears where you can
set:
1. Type of processing, cutting or emptying. In case of cutting
the position of the cutter in relation to the path can be
internal, central or external. Fig.6-4
2. The total depth of the path. NOTE: if the cutting depth
corresponds to the thickness of the panel, jumpers (tabs)
Fig.7-11 must be inserted to generate a connection
between the cut piece and the panel. This will prevent the
piece from moving once the cut is done. (NOTE Finish
the jumper insertion procedure by clicking the right mouse
button or the ESC button on the keyboard.)
3. Type of cutter, cutting parameters (you can choose among
the recommended and the custom ones Fig.6-5) (feed
rate, plunge rate and cutting depth) NOTE: The cutting
depth in relation to the total thickness of the cut
determines the number of passes.
To ensure the positioning of the working you can set JOG
mode, fully explained in the following paragraph.
At the end of the project preparation it is possible to send the
machining code (part program) to Goliath.
●Press the 'Calculate Path' button (Fig.7-8), which calculates
the optimization of the path for the chosen cut.
●The software displays the production page, Fig.8 and
Goliath moves the Z axis by lifting the spindle to the upper
position.
●The cutter can be replaced with the one indicated by the
software (see procedure in the following paragraph).
●Press the upper Goliath button (33) to calibrate the cutter
length.
●To start the process, it is necessary to press again the
button (33) located above Goliath, once the automatic cutter
length calibration procedure is completed.
●Goliath will start working on what has been designed.
●On the production page you can see the progress and the
portion of the work already done.
●The user will be notified with pop-ups if his intervention is
necessary.
●At the end of the process, the user receives an end of
working message and the production page can be closed,
allowing the user to return to the editor.
NOTE: Before starting machining, check that the status of the
electrospindle power key (46) is in the ON position.
NOTE: In order to ensure better internal cooling of Goliath
during machining, it is recommended, before starting the
milling, to remove the upper filter (24) to ensure a greater
volume of cooling air.
At the end of machining, reposition the filter to protect the
internal components of Goliath from dust.

Instructions for importing SVG files
In order to properly import svg files with the correct sizes, the
software allows 2 different import methods.
The first method allows you to import the project into the current
canvas, preset at 96 dpi, while the second method allows the
user to choose the dpi to which to import the project (72 or 96
dpi). Dpi is a unit of measurement that allows a correct scaling
of the vector svg format.
Some graphics programs such as Inkscape®, Corel Draw® or
Adobe Illustrator® allow the user to choose the resolution with
which to export the project.
In this case, simply select the resolution corresponding to the
one accepted by the software. Other programs like Rhino®
have a fixed export svg at 72 dpi. To know the details of the svg
export for each CAD program please refer to the manual of the
program used.
In case of problems importing the file, below you can find a
wizard for creating a .svg file compatible with the software using
the open source program Inkscape.
●Open the file in Inkscape
●Select all paths present
●File> Document properties
●Set Display units to mm or inch
●Choose a document format that contains the entire project
●In the custom size Units box, set the same unit of
measurement as the one selected for the Display Units
field. On the toolbar click on the padlock to maintain the
proportion of the path with size changes.
●In the W field: select the number and copy it
●Go back to the Document Properties box and in
Scale>Scale x set the field to 1
●On the toolbar, copy the previously saved value of W into
the W field. Check that the project is scaled as a result of
the change.
●Select all paths and use the command Object>Ungroup
●Object>Fill and Stroke
●From the Fill and stroke window, click Fill and select No
paint
●Click on Stroke paint and select Flat color
●If the svg contains concentric or complex paths select
Path>Break apart
●Place the paths inside the document
●Save as svg in the folder from where it will be imported into
SLINGSHOT software
Most CAD parameters are not optimized to export svg, so it is
recommended to export the drawing in .dxf. The .dxf format is
not supported by the software, but you can easily convert it
using the open source program Inkscape. The procedure for
creating a 96 dpi svg file is defined below:
●Launch Inkscape software
●Change the settings by clicking on Modify>Preference, click
on "Tools" and under "Bounding box to use" select
"Geometric bounding box".
●Use the "File>Open" command, select the .dxf file from the
window and click on "Open".
●In the "Input DXF" window select Method of Scaling: manual
scale, check that manual scale factor is at 1 and leave the
following parameters as already set by the software and
click on "OK".
●Select all paths and on the toolbar click on the padlock to
keep the path proportion and select and copy the number
inside the "W" (Selection width) box
●Modify the document properties by clicking on "File>
Document properties".
●Set Display units to mm or inch and in Scale>Scale x set
the field to 1
●Choose document format that contains the entire project
●Select all paths and on the toolbar replace the number in
the "W" field with the previously copied value Check that the
project will re-descale accordingly to the change.
●If the svg contains concentric or complex paths select and
use the command "Path>Break apart".
●Place the paths within the document
●Use the "Save As" command and save the file as .SVG in
the folder from where it will be imported in the SLINGSHOT
software
Although there are several dxf to svg online converters, these
do not always give results consistent with the initial project. For
a correct import it is recommended to perform the procedure
described above.
Remember that if you want to work on an imported project
whose resolution is 72 dpi, the project must be imported into a
new canvas and only then the panel detection must be done.
The flow of actions to be performed once in the editor is as
follows:
●Select import in new canvas
●Choose the svg project to import
●Choose 72 dpi
●Import
●Carry out panel detection
●Choose the svg project to import
Disclaimer: If after converting the figure from dxf to svg the
paths are imported as unopened, this is a problem of how the
figure was generated in the original cad.
SLINGSHOT includes JOG mode (manual movement control),
Fig.9. It allows the user, after panel detection, to simulate
Goliath’s movements on the panel. It is particularly useful to
place the workpiece, displaying on the panel that it does not
interfere with previous cuts or imperfections that cannot be
detected.
After pressing the JOG button, wait for the spindle to move to
the safety level.
In JOG mode you can control Goliath in 3 different ways:
1. Manual positioning
2. With x,y and angle coordinates
3. Via joystick
In the first case click on the Manual button (Fig.9-12) and,
grabbing Goliath’s handles, slide the machine to the desired
point on the panel. The real movement corresponds to an
equivalent movement on the screen of the software that
updates the position of Goliath. To end the movement mode,
click on the “Manual” button, which allows to switch on the
motors and exit the manual positioning.
Springa Srl, via Giovanni Durando 38/A, 20158 Milan, Italy Operating manual GOLIATH Ver.01/2020 17

The movement by coordinates is obtained by entering the point
of the panel and the desired orientation in the appropriate fields
(Fig.9-13) and clicking the GO button.
The movement stops as soon as the robot recognizes the
target position. If you want to stop the movement before
reaching the target position, you can click on the STOP button
again.
The third option allows you to vary the position of Goliath and
not its orientation. This method is particularly suitable for
precision movements.
The user can choose the length of movement(Fig.9-14) among:
●10 mm
●5 mm
●1 mm
Once the length has been chosen, set the direction of the
movement by pressing the corresponding arrow button. Goliath
will move accordingly.
These last two modes are allowed only if Goliath is more than
400 mm from the edges of the panel for safety reasons.
USE PROCEDURES AND ADJUSTMENTS
Tool assembly/replacement
The assembly of the tool must take into account all the safety
recommendations described in the previous parameters.
Perform the following mounting procedure:
IMPORTANT: The mill can only be replaced during the working
cycle.
Tool replacement
Goliath allows the tool replacement mode during the working
cycle: Every working launch, Goliath will suggest a tool
replacement, positioning the spindle in the upper zone of the
vertical axis (Z axis).
Follow the procedure below to replace the tool:
1. Remove transparent electrospindle protection (19)
2. Using the tool locking wrench (14) and holding down the
manual spindle rotation lock button (15), unscrew the tool
locking ring nut (12).
3. Replace the tool using the corresponding tool clamp (13)
with the appropriate size according to the tool shank
diameter (11).
4. Lock the ring nut using the tool clamping wrench (14) and
holding down the electrospindle rotation manual locking
button (15).
5. Attach transparent electrospindle protection (19) making
sure that the electrical contacts of the electrospindle
protective cover (21) are in the correct position.
6. Press the Goliath status button (33) above Goliath to
confirm the end of the tool change procedure.
In case Goliath already has the correct tool mounted, you can
confirm immediately by pressing the Goliath status button (33)
in the HMI above Goliath (skip steps 1 to 5).
At the end of the procedure and after pressing the confirmation
button, Goliath automatically starts the tool zeroing procedure
with the slow descent of the Z axis to touch the panel in
process.
Once this operation is complete, Goliath will start or continue
the cutting process.
Spindle Setup Adjustment
Depending on the type of material to be worked and the type of
tool used, Goliath software automatically adjusts the feed
speed. The rotation speed must be adjusted manually through
the spindle speed potentiometer (06) located on the top of the
spindle.
WARNING: Before each machining operation, check that the
electrospindle unit is properly secured so that it cannot be
removed with the protective cover on.

WARNING: Setting a tool rotation speed higher than the speed
limit specified by the tool manufacturer may create a danger of
ejection of parts of the tool.
Emptying of the chips collection tank
Emptying the chips collection tank (7) may be necessary
during, before or at the end of the working cycle.
In the first case Goliath will go in an area previously defined
during the programming phase and a message appears in the
operator interface of the software.
From now on, the procedure is as follows:
Grab the chips collection tank (07) by simultaneously acting on
the release lever (08) positioned on the top of Goliath.
Remove the swarf collection tank with a movement parallel to
the working surface, after the detachment from Goliath hold the
swarf collection tank (07) using the handle (56) in the middle of
it and take care to avoid tilting the tank downwards in order not
to lose swarf from the suction inlet hole.
Position yourself above the chips discharge point and open the
rear door (10) using the lever (09).
Be sure to remove all the chips in the tank (powder is very
compact especially in the area away from the inlet duct.)
Carefully clean the closing gasket of the door (10) with
compressed air or a dry cloth.
Close the door making sure that the lever (09) ensures the door
is closed perfectly.
Insert the chips tray into the slide rail of Goliath, making sure
that at the end of the stroke the locking lever (08) is correctly
engaged.
Only in case the emptying of the chips collection tank occurs
during the cutting cycle, Goliath must be restarted by pressing
the button (33) located on the HMI interface on the robot.
