The height of the spray gun affects the width
of the spray pattern (i.e., the lower the gun, the
smaller the line width). Tip size also affects line
width.
i
It is recommended that both spray guns be
installed at the same height as a starting point.
The gun heights can be adjusted individually
based on spraying needs (i.e. spraying a curb or
spraying two lines of different widths).

SETTING THE TRIGGER SELECTOR (IF
APPLICABLE)
1. Set the trigger selector for proper spray gun operation
(Fig. 17). The right handlebar triggers the gun or guns. The
selector on the trigger must be set for the first gun, both
guns, or the second gun.
Attention
Always turn the trigger lock on the spray gun
to the locked position before making any
adjustments to the trigger selector. Also, release
the trigger cable from its block by lifting the
cable up and out of the block. There will be a
brief triggering of the gun while releasing the
trigger cable.
a. First Gun — The first gun position is with the selector in
the left position. Push the lever toward the inside of the
frame until the pin engages the left plate.
b. Both Guns — The dual gun position is with the selector
in the center position. Push the lever toward the center
position until the pin engages both plates. The pin must
engage both plates.
c. Second Gun — The second gun position is with the
