When the wear pads are worn to 6 mm (0.23 in) or below they should be replaced.
It is permissible to rotate the top wear pads 180°„ to prolong service life, provided the contact surface is more than 6 mm (0.23 in) thick.
Note: If rotating the wear pad the grease nipples will have to be swopped over.
