NOTE: This procedure is only necessary when the sys-
tem will not be used for more than a few hours. The pri-
mary purpose of this procedure is to prevent material
from hardening on the metering pump shaft by extend-
ing the pump so the portion of the shaft that is exposed
to material is not exposed to the air.
1. Turn the metering pump air regulator (CD) counter-
