Adjust the air cap
Slacken off the retaining ring slightly and turn the air-cap
to the required position to produce a horizontal or
vertical spray pattern.
The horizontal spray is generally used when painting up
and down and vertical spray when painting across.
Switch on the blower unit
Note that air flows from the nozzle at all times.
Paint will flow only when the trigger is pressed.
Adjust the paint control
This knob adjusts the amount
of paint released through the
nozzle when the trigger is
pressed.
To set the paint control, spray
a test pattern onto a sheet of
paper or scrap material placed in
an upright position.
To do this, first turn the paint
control fully clockwise then
unscrew about 4 turns
(clockwise as you face the
work).
Hold the gun with the nozzle
about 15 to 20 cm from the
surface. Squeeze the trigger
briefly.
Do this several times, adjusting the paint control each
time until the spray pattern has the required width and
produces a good wet coat without runs. Carry out a final
test by squeezing the trigger and moving the gun parallel
to the surface work to check that a good smooth
coat is applied. Adjust your
speed of movement and the
paint control if necessary
. Overlap each new pass by
about one third to give even coverage. (See diagram on
opposite page).
When spraying a large surface such as a wall, screw out
the paint control to give a wider fan pattern, without
going so far that you get coarse splattering spray.
When spraying a narrow surface, such as a chair leg,
screw in the paint control to give a spray about the same
width as the leg. Also, move the spray gun slightly closer
to the work.
