thin areas of material might be noticeable compared to the volume delivered in the

middle of the stroke, see figure above.

Probable Cause: There is no or improper accumulator effect in the resin system.

Solution: Resin accumulator full of hard material or has a blockage, clean resin

accumulator. Clean resin filter and reinstall. Incorrect accumulator installed.

Pump pressure is too high, lower resin pressure. See chapter 5 for accumulator

charging procedures

NOTE: Use caution as there may be some material still in the accumulator, a long

narrow rod can be inserted up through the filter body to lift the polyball off the

seat and allow any remaining material to drain if desired.
