III.8 Removal of Trough and Lid from Instrument
When the test is complete, the Lid will automatically raise up a small distance off of the trough.
This is a visual indication that the test has ended. Push and hold the UP arrow on the instrument
control panel until the Lid has raised to its upmost position. Then disengage the Lid from the
CompressionPlatebypressingthereleasebuttons(SeeFigureIII-3b).Cleantheexcesspowder
that clings to the Lid.
Remove the Outer Catch Tray from the trough and dispose of the excess powder in the Tray.

been trapped in the openings. To remove the perforated screen, unscrew the three screws located
underneath the trough.
III.9 Clean-up
The Cleaning Brush serves to remove excess powder from the Trough and Lid. This may be
adequateforrepeatedtestingofthesamepowdertypeswherethepotentialforcross-contamination
between samples is not really an issue. Be sure to clean pins of the lids and compression plate
to ensure proper alignment.
For more thorough cleaning, the use of an air hose, water, or a cleaning solvent may be desired.
Whenusingaliquidforcleaning,makesuretodrytheTroughandLidthoroughlysothatmoisture
contamination does not become an issue with the next sample.
Do not use compressed air to clean the PFT.
