• Filling the MEK Reservoir (page 11)
• Testing a panel (page 12)

lever to lower the block)
2. Set number of double rubs (see previous page)
3. Press the start (Green) button. On completion of
the preset number of strokes the machine will stop
automatically.
You can stop and start at any point during the count down with no interruption to the cycle
total (i.e. the stop button is depressed during a cycle the counter stops at 25 strokes remaining,
pressing the start button will begin the count down from that point, 25 remaining strokes).
Dierent pad materials will aect your test results, if you are trying to correlate your results
with another unit it is important to make sure that you are both using the same pad material.
e cotton pads provided with the machine are ASTM compliant and can be purchased
through DJH (PN: 1963)
To establish the required number of strokes that is acceptable to your standards, run a known
panel by your hand method, and run a parallel test on the same panel with the machine. Stop
the machine when the results appear similar. is will be your new test requirement.
