• Slacken bolts (1) and shift holders (2) towards the drum for
15 mm (0,6 in) distance between the scraper and the drum.

holes of holders (2) when scraper (3) gets worn,
remove the scraper (3) and move it by one hole to-
wards the drum.

• Slacken bolts (1) and shift individual scrapers (2) towards the
drum at 25 mm (1 in) distance.
! CAUTION !
Rear scrapers at padfoot drum are longer. When re-
placing worn scrapers use rear ones instead of front
