Mixing Material - Graco 254974 Operation Manual

Mixing Material

Correct material mixture is essential. The pump
will not operate if the mixture is too thick.
Mix the material in a separate container before
pouring it into hopper.
Use Material Thickness Gauge to determine mix-
ture is thin enough to spray.
*The Material Thickness Gauge will only deter-
mine if the material is thin enough to pass through
the pump. For some applications or for higher
speed spraying, your mixture may need to be thin-
ner.

tency.
