Before attempting this operation please use insulate gloves. To switch between noz-
zle sizes to heat up the unit to175c. Unscrew the nozzle, clean off any excess plastic
from the internal threa s, then screw on new nozzle.
COLOUR MIXING
A ing colours is simple. Mix the natural an 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 colorants to create new colours. For example, mix blue an yel-
low make green.
MAINTENTANCE
Regular cleaning of your plastic extrusion tooling uring the isassembly process
lengthens tooling life, helps re uce waste an helps maintain tighter tolerances for
your final pro uct. Use a wire brush an fine metal pick to clean the threa s an the
screw assembly
LUBRICATION
The thrust bearing assembly will require occasional lubrication; this is a relatively sim-
ple operation, simply unscrew the brass grease nipple an squirt a 2 secon burst of
a lubricant like WD40 Lithium Grease. For optimal performance we recommen this
proce ure is carrie out every 100 hours of operation.
BARREL JAM
Depen ing on what type of resin you are using, you may experience a barrel jam. If at
any time uring extrusion the motor starts to labour an slow right own then you
shoul switch off the motor imme iately. A goo way to free the jam is to turn the
temperature up to aroun 230-240c an leave this for 15 – 20 minutes, then switch
on the motor again; this shoul allow the screw to rotate again. Also using a blow
torch to heat the barrel just past the hopper will usually release any soli ifie plastic
an free the screw.
MOTOR BLOCK
pWhen the motor blocks, it's likely that the fuse has blown. Check insi e the casing,
you'll see it fuse fixe to the bottom, Replace with a 15amp fuse.
