Checking - Setting
If one of the water pumps stops, the remaining pump
will be able to keep the sprinkler system operating -
however, at reduced capacity.
To operate with only one pump, open the stop cock (1)
in the water hose by the articulation, and also the stop
cock (2) on the coarse filter by the pump that has
stopped, see pump system.

Make sure that the scrapers are undamaged. Adjust the
scrapers so that they lie 1–2 mm (0.04-0.08 in) from the
drum. For special asphalt compounds, it may be better if
the scraper blades (1) lie lightly against the drums.
Asphalt remnants can accumulate on the scraper and
affect the contact force.
Loosen the screws (2) to adjust the scraper blade up or
down.
Loosen the screws (3) to adjust the contact pressure of
the scraper blade against the drum.
Remember to tighten all the screws after any adjustment.

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
affect the contact force. Clean as needed.
The scrapers must be retracted from the drum
during transport driving.
