15.7.4 Trapezoidal packer roller scrapers
The trapezoidal packer roller is fitted with
scrapers (1) whose distance from the roller
casing (4) can be adjusted with eccentric
nuts (2).
Undo the bolt (3) of the eccentric nut (2)
using a 19 mm spanner.
Adjust the eccentric nut (2) using a 24
mm spanner. The distance of the scrap-
er (1) from the roller casing (4) must be
between 0.1 mm and 0.5 mm.
Rotate the roller 360°.
The scrapers must not touch the roller cas-
ing in any rotational position.
If a single scraper (1) touches the roller
casing, it must be adjusted so that it is
again at a distance of between 0.1 and 0.5
mm from the roller casing (4) in the nar-
rowest position.
Securely tighten the screws (3) again
(80 Nm).
Retighten the screw (5) that may have
come somewhat loose due to the ad-
justment (80 Nm).
