CLEANING THE INSTRUMENT IS BEST ACHIEVED WHILST
COMPONENTS ARE HOT, HEATPROOF GLOVES SHOULD BE WORN AT
ALL TIMES.
The clean option can either be accessed after performing a test or through
the options menu.
1.
Once the test has been completed, the remaining polymer can be
extruded from the orifice by manually pushing down on the weight.
Once all remaining polymer has been extruded and discarded, pull out the
die retaining slide so that the die drops out of the bottom of the barrel.
TO AVOID DAMAGING THE DIE CATCH IT IN THE PALM OF A
HEATPROOF GLOVE.
Sometimes the die can get stuck in the barrel.
If the Die does not fall out of the barrel place the glove under the barrel
and continue to stage 2, when the cleaning probe enters the barrel it will
push the die out.
Whilst the die is still hot, use the die broach to remove any polymer from
inside the orifice. Use the cut off knife to scrape any remaining plastic
from the outside of the die.
Place the clean die to one side.
Use the cut off knife to remove any material from the die retainer slide
.
2.
Remove the test piston and scrape any remaining polymer from the shaft
using the cut off knife. Use a cleaning patch to remove any further residue.
