1.0 Safety
The safe operation of the Airwolf 3D Printers depend on its proper use and the precautions taken by each
operator.
•Read and study the Airwolf 3D Printers manual carefully. Be certain that every operator
understands the operation and safety requirements of this printer before its use.
1.1 Safety Publications
Please note that FFF/FDM 3D printing can produce hazardous Ultra-Fine Particles (UFP’s) and Volatile
Organic Compounds (VOCs). Our 3D printers come with a HEPA Filter and enclosed print chamber to help
reduce the amount of UFP and VOC’s you come in contact with. Always close the print chamber door and
make sure the HEPA filter is replaced as recommended.
1.2 Safety Labels & Notices as Used in this Manual
•DANGER - Immediate hazards that will result in severe personal injury or death.
•WARNING - Hazards or unsafe practices that could result in severe personal injury and/or
damage to the equipment.
•CAUTION - Hazards or unsafe practices that could result in minor personal injury or
equipment/product damage.
•NOTE - Call attention to specific issues requiring special attention or understanding.
1.3 Safety & Information Labels Used on the EVO-T and EVO22-T
It is forbidden by OSHA regulations and by law to deface, destroy or remove any of these labels from
the printers.

1.4 Safety Precautions
•The heated bed can reach temperatures of 160°C and also generates heat inside the enclosed
chamber of 70°C. The hot end reaches temperatures of 315°C. Never touch the heated bed or
hot end while hot, and keep in mind they may take a long time to fully cool down.
•Recently extruded plastic can stick to the skin and cause burns if not careful. Always wait until
the heated bed or hot end is completely cool before removing unwanted plastic or debris. The
stepper motors can also generate high temperatures and contact with the skin should be
avoided.
•Flammable materials or liquids should never be placed, stored next to, or in the printer.
•The internal electronic components can cause electric shock even when the printer is powered
down or unplugged. Never remove the back panel without consulting TRAK first.
•ALWAYS disconnect ALL power to the printer before performing any repairs.
•Never touch moving parts or place your fingers in or on any of the belts, pulleys or gears while
the printer is operational. Make sure to tie back hair and remove any dangling jewelry.
•For safety, we highly recommend hooking up an external video camera for video monitoring
while printer is unattended.

3.0 Installation Process
In this section we will walk you through the installation process, from the moment your printer arrives, to
the moment that it is powered on and ready to start printing. Do not proceed with this section, or the
following sections until the Site Preparation & Requirements section has been completed.
3.1 Lifting, Moving, Uncrating, and Unpacking
In this section, we will go over getting your printer out of its box safely. The procedure for both printers
is nearly the exact same, except for steps 6-8 due to the way they are packaged.
Lifting/Moving while on a Pallet
oThe best option for lifting the Airwolf EVO-T and EVO22-T 3D Printer is a pallet jack.
oThe second-best option is using four (4) people (so that each person does not carry more
than 50 lbs.).
Lifting & Moving after Uncrating
oOnce the printer has been removed from the pallet, it must be moved by hand. Two (2)
people are recommended to move the printer by hand.
Uncrating & Unpacking
1. Cut off the straps that are holding the main box (which contains the actual Airwolf EVO-T 3D
Printer) and the secondary box (which contains the 3D printer’s accessories) to the pallet.
2. Remove the plastic wrapping that surrounds both the main and secondary boxes together.
3. Remove the secondary box that contains the 3D Printer accessories, and put it aside for now.
4. Cut open the taped flaps that cover the main box by using a box cutter. Be careful not to cut too
deeply as you might risk damaging content inside the main box. In addition, preserve the main
box in the case that it might be needed for returns and/or any possible customer service issues
that might arise regarding the Airwolf EVO-T 3D Printer.
5. In addition to the Airwolf EVO-T 3D Printer, there will be shipping documents that are included
inside the main box. Remove these documents, and put them aside for now.
EVO-T ONLY
6. The Airwolf EVO-T 3D Printer will be standing in an upright position while inside the main box.
Remove the protective foam parts that are covering each of the 3D Printer’s corners prior to
removing the printer out of the box.
7. Pull the printer UP by its straps. Use two (2) people to lift the printer out of the box.
8. Lift the printer on top of a table, stand, or workstation. Cut off the straps around the 3D Printer,
and remove them.
EVO22-T ONLY
6. The Airwolf EVO22-T 3D Printer will be lying horizontally on its side while inside the main box.
Remove the protective foam parts that are covering each of the 3D Printer’s corners prior to
removing the printer out of the box.
7. Tilt the box on its side in order to remove the 3D Printer outside of the box. The Airwolf EVO22-T
should now be standing upright. Use two (2) people to slide the printer out of the box.
8. Lift the printer on top of a table, stand, or workstation.

9. Remove the protective plastic wrapping that surrounds the 3D Printer.
10. Please note that the 3D Printer’s glass cover (which is wrapped in paper) is taped on the very top
part of the printer itself. Remove the tape holding the glass cover, and put it aside for now.
11. Remove the tape that keeps the 3D Printer door closed, and open the printer door.
12. Remove the two (2) zip ties around the two (2) chamber heaters inside the 3D Printer.
13. Remove both the zip ties and the white clips that are attached to the left and right belts, which
are located on the upper interior surface of the 3D Printer (see image below):
NOTE –When removing the zip ties, be careful not to cut the left and/or right belts, as well as
any internal cords within the 3D Printer. Doing so will cause damage to the printer.
14. Remove the clip attached to the Z Stage Ball screw by pulling on the zip tie that is attached to
the clip.

3.3 Benchmark Part: Euclid Block
In the accessory box, with your new printer, you will
find a 3D printed part, called a Euclid Block. We
printed it directly from your printer, using MG94
ABS, and the exact same G-Code file that we saved
onto your printer's Internal Drive as "LEFT TRAK".
Purpose
The Euclid Block helps establish a printing baseline
for your printer, which we can reference if/when you
are experiencing any printing issues.
Because 3D printed parts can differ from one
another based on many variables; material type, material care, slicer settings, printer, printer
maintenance, and so on, diagnosing a problem can be difficult to isolate.
Therefore, by using the G-Code we provided, we are controlling the slicer setting variables. By using the
material we provided (make sure its dried!), we are controlling the material variables.
Now we can begin to isolate the problem in a much more controlled manner!
Printing the Euclid Block
When you print it, make sure you follow the requirements below:
•Use MG94 ABS, natural color, and make sure it is DRY.
•Use the exact same G-Code we saved on your internal drive. If you need another copy, call TRAK
Customer Service.
•Make sure you watch the first layer print before walking away from your printer.
Troubleshooting
Once the Euclid Block is printed, you can look at it, and see what it is telling you. Is there warping? Are
the layers delaminating? Are there bubbles on the top layer? Are the top and bottoms layers bigger than
the middle layers? Is the overall print quality bad?
Below is an example of how we can help you start troubleshooting, using the Euclid Block:
Example #1
The first layer of your block did not adhere to the build plate. One potential cause could be the WolfBite.
WolfBite Issues and Solutions
1. Not enough was applied initially. Remove & apply more before restarting the print.
2. Too much was applied initially. Remove & apply again before restarting the print.
3. It did not dry sufficiently, allow 5 minutes the next time you apply it
4. It needs to be replaced, it is either too old or the wrong kind
If the WolfBite suggestions above did not fix the problem, the next steps would be to check if the
chamber heater needs to be on. If that didn’t work, then you would move onto the next potential cause.
Regardless, if your printer has an issue, call TRAK Customer Service to have a Technical Support, or
Applications Specialist walk you through the process –you’re not alone! We’re here to help.
