Take the grease samples from the main loading zone.
Remove the screw plug (M16 EN ISO 4762) selected
for taking the sample: item 1 and if necessary item 2
opposite (fi gures 12 and 13).
Before taking the grease sample, cut the supplied tube
at an angle of 45° so that it is slightly longer than the
grease sampling port. Then insert the tube into the race-
way area of the port (fi gure 14).

When the sample has been taken, close both tube
ends with the plastic caps.
Number the grease sample and place it in the labeled
