Safety Instruction
Building the printer will require a certain amount of physical

GEEETECH

dexterity, common sense and a thorough understanding of what you are
doing. We have provided detailed instructions to help you assemble it
easily, please download at geeetech.com.
However ultimately we cannot be responsible for your health and
safety whilst building or operating the printer, with that in mind be sure
you are confident with what you are doing prior to commencing with
building or buying. Read the entire manual to enable you to make an
informed decision.
Building and operating involves electricity, so all necessary
precautions should be taken and adhered to, the printer runs on 12V
supplied by a certified power supply, so you shouldn’t ever have to get
involved with anything over 12V but bear in mind there can still be high
currents involved and even at 12V they shouldn’t be taken lightly.
High temperatures are involved with 3D Printing, the Extrusion
nozzle of the hot end can run about 230°C, the heated bed runs 110°C
and the molten plastic extruded will initially be at around 240°C, so
special care and attention should be made when handling these parts of
the printer during operation.
We wouldn’t recommend leaving your printer running unattended,
or at least until you are confident to do so. We cannot be held
responsible for any loss, damage, threat, hurt or other negligent result
from either building or using the printer.
INSTRUCTION:
This Prusa I3 A pro 3D printer is modified and optimized based on
the previous Geeetech PrusaAluminum I3 3D printer.

As you can see, the most obvious modification is that we add a
3-in-1 3D printer control box for this Prusa I3 A pro which gathers the
motherboard, power supply and LCD Cpanel in one box, saving the
space taken by the printer and bringing you a neat and organized
desktop, most importantly, the power supply is installed inside the
control box now, which is not only for protecting the power supply, but
also for eliminating unnecessary dangers, protecting your family and
your pets.
This Prusa I3 A pro 3D Printer DIY kit offers a significant
experience for you to learn 3D printing from scratch, this kit that
includes all the parts you need to build your first 3D printer will be the
best valued purchase for you. If you are a starter, we have manuals and
videos for step-by-step assembly and an active support service via
forum to help with any queries.

GENERAL CARE AND MAINTENANCE
As with all the electronic equipment, it is important to keep your printer
clean to extend its life. Regularly remove dust and debris with a
microfiber cloth or compressed air. Dredge the tube and the nozzle after
use every time to ensure fluent performance.
Don’t leave the heaters on the printer turned on for a long
periods of time when not used.
Don’t leave your printer in shady and moist places, which may
exacerbate the problems associated with erosion.
The three axes of the GeeetechPrusa I3 Aprinter are lubricated
with grease for smooth operation and can last for a long time.
Grease may need to be re-applied to your printer to maintain
smooth performance.
