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.
Use oil-based material outdoors or in a well-ventilated indoor area with a flow of fresh air.
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 material 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 con-
tains a non-mineral spirits fluid such as, but not limited to, xylene, toluene, or naphtha, which can build up
static. Switch to an alternative material.
