4.4.1.3 Triggering. Proper triggering of the gun is
difficult to learn. The variations of triggering technique which
may be called for in special situations can only be developed
by practice. It is a matter of judgment and experience. In
general, the painter should begin his stroke before triggering
the gun and release the trigger before stopping the stroke. It
can be compared to the follow-through in swinging a golf
club. This tends to feather out the end of a stroke so that the
end of a succeeding overlapping stroke blends into it.
Examples of correct techniques are shown in Figure 4-7.
NOTE
• A reasonable amount of care will maintain
spray guns and spray equipment in top oper-
ating condition and prevent a majority of
spraying difficulties. Thorough cleaning im-
mediately after use and appropriate lubrication
are essential.
• This manual provides only general spray gun
information. See specific manufacturer’s
booklet or manual for detailed operating and
maintenance instructions.
