1. Locking screws
2. Scraper
Make sure that the scrapers are undamaged. Adjust
the scrapers so that they lie 1–2 mm from the drum.
For special asphalt compounds it may be better if the
scraper blades (2) lie lightly against the drums.
The remains of asphalt can accumulate on the scraper
and thus influence the contact force.
Loosen the screws (1) to adjust contact pressure of the
scraper blade against the drum.
Remember to tighten all the screws after any
adjustment.

Scrapers, spring-action
(Optional) – Check
Fig. 13 Spring-action scrapers
Make sure that the scrapers are undamaged. The
spring-action scrapers require no adjustment because
the spring force provides the correct contact force.
Asphalt remnants can accumulate on the scraper and
influence the contact force. Clean as necessary.
Make sure the scrapers are retracted from the
drum during transport driving.
