Metering Rollers
The metering rollers should be removed,
cleaned and inspected for damage on a daily
basis. Grooving or flattening of the metering
roller surface can drastically alter the metering
rate. Damaged rollers must be replaced.
Keeping the applicator free from moisture will
help to prevent product from building up on the
rollers.
Metering Roller Gap (Fig. 6-8)
The gap between the metering roller and the
metering lip is preset at the factory. Should the
gap need adjustment, do so as follows:
1. Loosen the bolts securing each bearing
housing to the bottom assembly.
2. Insert a ¼” spacer for the RED and GRAY
rollers.
3. Tighten the bearing housing bolts. Remove
the spacers.

follows:
1. Push down the shut-off plates if hopper is
not empty.
2. Lower the manifold and install the funnels
along with some collection containers.
Release the bearing clips and remove the
metering rollers.
3. Clean the metering rollers, metering roller
area, bearing seats and venturis.
