WARRANTY NOTE
Equipment manufactured by Noztek carries the standard machine tool guarantee
of freedom from defects in workmanship and material for one year from date of
shipment.
TO INSURE THAT YOUR WARRANTY IS HELD IN EFFECT, PROPER
OPERATION PROCEDURES MUST BE OBSERVED.
NOTE: READ THE SAFETY PRECAUTIONS BEFORE OPERATING THIS
MACHINE.
GENERAL SAFETY NOTES
Know your equipment
Carefully read the instruction manual.
Learn the use and limitations of the equipment.
DO NOT operate or use this equipment for any purpose other than its intended
use.
DO NOT modify this equipment.
DO NOT perform adjustments or maintenance while system is operating or
energize
Do not clean the equipment with flammable solvents.
Do not wash down the equipment with water. This could cause an electrical
hazard.
Do not probe into extruder vent with the machine running. Never Use a metal
probe in the vent area. The screw may shear the probe, causing extensive
damage to the barrel and screw. A wooden probe is recommended.
A face shield, insulated gloves, etc. should be worn around the extruder during
operation. They must be worn when adjusting the die, cleaning the screw, etc.
The extruder temperatures are extremely hot.
The feed hopper must be installed on the extruder feed section at all times when
in operation
Never put hands in the feed section or vent to remove material.
Do not switch on the motor until the recommended temperature has been
reached

Introduction
The Noztek desktop extruder has been designed to produce high quality ABS
and PLA filament for use with 3D printers. For best results we recommend using
extrusion grade polymer pellets.
Maintenance
Your Noztek Pro comes complete with an emergency stop button. If you are
using the 45 degree bracket it is very important that the extruder is secured to a
workbench using the mounting holes in the bottom of the bracket.

In an emergency simply hit the button and the Noztek Pro will completely switch
off. To restart, simply untwist the button.

Remove the unit from the packaging
If you are using the 45 degree bracket, secure the extruder to a bench
using the mounting holes.
Make sure you are in a well ventilated area
Plug the extruder into the mains.
Switch on the heater element and adjust the temperature gauge to the
desired setting. For ABS we recommend between 180 – 200 degrees
Celsius and PLA between 165 -175c. To adjust the heat setting press the
set key once, the temperature led will then flash, then the click up or down
key to adjust. When you reach the desire temperature click the set button
to engage. Let the extruder barrel heat fully this should take about 15
minutes.
Once the required temperature has been reached, fill the hopper with
resin pellets.
Switch on the screw motor (Do not switch on the motor until the
recommended temperature has been reached).
Switch on the fan
After a few minutes you will see plastic filament starting to extrude,
carefully feed this through the guide, This filament will be hot so use heat
resistant gloves
Extrude approximately 5m of filament, switch off the motor, cut off the
excess material, and then restart the motor. This should help to eliminate
any air bubbles and metal particles in the system.
Adjusting the temperature also affects the tolerance of the filament. The
higher the temperature, the thinner the filament. The lower the
temperature, the thicker the filament.
Make these adjustments in 5 degree Celsius increments.
If the extruder is left unattended for any period of time we recommend
using a mains timer switch.
Changing the nozzle
Before attempting this operation please use insulated gloves.
To switch between nozzle sizes to heat up the unit to175c, unscrew the nozzle,
clean off any excess plastic from the internal threads, and then screw on new
nozzle.

Colour Mixing
Adding colours is simple. Mix the natural and the colorant at the given ratio. Then
pour it into the hopper. It will take 10-20 minutes to see changes in the colour. It
is also possible to mix colorant to get new colours. For example, blue and yellow
make green.
Maintenance
Regular cleaning of your plastic extrusion tooling during the disassembly
process lengthens tooling life, helps reduce scrap and helps maintain
tighter tolerances on your final product. Use a wire brush and fine metal pick to
clean the threads and the screw assembly.
Note: Common practice is to use a propane torch to burn out excess material
from the tip.
CAUTION: Do not heat excessively or cause material to be red hot.
