NOTICE NOTICE
To prevent material curing in system, never load
mortar or epoxy into a dry system. Loading mortar
or epoxy into a dry system will cause the material
to stick to internal components and cure causing
damage and requiring replacement of those parts.
Always wet out the system by circulating clean
fluid through the applicator back into the hopper
before loading any mixed mortar. This is normally
done with the flushing fluid, but sometimes resin
or commercially available concrete pump priming
fluids are used depending on what material is being
sprayed.
• Use the material flushing agent recommended on
the material application data sheet.
• When finished, pump out the excess fluid. Then
drain out remaining fluid by loosening the bottom
cam fitting.
1. Close the bleed type master air valve (B).
