CA 150/152 W1080EN1

Adjust the scraper between scraper tooth and drum

shell to a distance of about 25 mm (1").

It is important to remember that the drum tends

to move as the machine turns. Consequently,

if adjustments are made closer than the values

specified above, the scrapers might be dam-

aged or drum wear may increase.

Torque-tighten the four bolts according to drawing

38 53 45.

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.

This is necessary to compensate certain

settling of the drum shell. If retightening is

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.
