UNPACKING & INSTALLATION

Replacing the Rubbing Pad

The MEK rub test machine is equipped with a safety
latch device, this latch will prevent the head from in-
advertently falling back down onto the base plate if the
machine happens to be bumped or if the head was not
raised up fully to the over centre position of the head.
Raising the head requires no operator interaction with
the latch; the unit is spring loaded and will slide back as
the head is raised against it. Once the head is raised past
the latch point the latching device will snap back into
place the head is now in the up and locked position. To
lower the head, raise the head up fully if it is resting on
the latch and with your free hand depress the latch and
lower the head.
1. Rotate the holding plate 90° and lift off. The plate is
magnetically held to the rubbing block.
2. Remove the old pad and discard
3. Cut the cotton pad into quarters and place the clean pad
(approximate size 1½ x 1¾), double ply, diagonally over
the plastic button, corners of the pad between the magnets.
4. Re-attach the plate at 90° and rotate back into original
position
5. Wet the new pad with the MEK
