Materials; Starting A New Job - Graco ProShot 258865 Operation Manual

Materials

Use only water-based or oil-based (mineral
spirit-type) materials with flash point greater than
100° F (38° C). Do not use materials which state
"FLAMMABLE" on the packaging. For more information
about your material, request MSDS from distributor or
retailer.
Spraying certain materials may cause static
build-up in the sprayer that can result in static
shock to the user. If this occurs, first ensure the mate-
rial has a flash point greater than 100° F (38° C) and
does not state that it is FLAMMABLE anywhere on the
package. If still feeling a static shock, the material likely
contains a non-mineral spirits fluid such as, but not lim-
ited to, xylene, toluene, or naphtha, which can build up
static. Switch to an alternative material.
Use oil-based material outdoors or in a well-ventilated
indoor area with a flow of fresh air.
Keep spray area well-ventilated. Keep a good supply
of fresh air moving through the area.
• When spraying water-based materials, flush the
sprayer thoroughly with water.
• When spraying non-water-based materials, flush
the sprayer thoroughly with mineral spirits or com-
patible, oil-based flushing fluid.
