1.
The motion plate and abradant plate should be parallel. Insert a dial gauge through the sample
holder bearing and inch the top plate.
The needle movement over the dial gauge should be within ±0.05mm over the whole surfaces
of the abradant tables (with the abradant cloth removed).
2.
Assemble each sample holder complete with the weight and place each one in position on the
appropriate table.
Use a feeler gauge to check for any gap between the face of the specimen holder and the table.
3.
to adjust tables, slacken the central screw and adjust as appropriate using the three jacking
screws located on the main deck plate.
When complete, re tighten the central securing screw.
4.
to adjust the motion plate, slacken the locking nut fitted to the stem of the three ball carrying
cups rotate the cups to the correct height and re tighten the locking nuts.
