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 contains 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.

Basic Spraying Techniques
NOTE: Use a piece of scrap cardboard to practice these
basic spraying techniques before you begin spraying the
surface. Anything you don’t want painted that is in
the area of your spraying surface should be covered
or removed.
Hold sprayer at least 25 cm (10 in.) from surface and
adjust accordingly to achieve desired results. Aim
sprayer straight at surface. Tilting sprayer to direct spray
angle causes an uneven finish.
Flex your wrist while moving your arm to keep the
sprayer pointed straight. Tilting the sprayer or spraying
at an angle causes an uneven finish.
Triggering Sprayer
Pull trigger after starting stroke. Release trigger before end
of stroke. Sprayer must be moving when trigger is pulled
and released.
Aiming Sprayer
Aim tip of sprayer at bottom edge of previous stroke, overlapping each stroke by half.
NOTE: How fast you move the sprayer will affect spray
application. If material is pulsating, you are moving too fast.
If material drips, you are moving too slow. See Trouble-
shooting, page 18.
