The pad shell is now fitted and the roller is ready for
operation.
After a short test-run of about 1/2–1 hour,
retighten all of the bolts that have been fitted,
and again after another 4 hours of operation.

neglected, the shell may rotate on the drum
and result in serious damage to the pad shell.
Before dismantling the pad shell, mark the halves in
some permanent way to show how they are positioned
in relation to each other.
The hole pattern and any wear to the shell necessitate
refitting the shell to its initial position.
