Spraying Techniques

Preventing Excessive Tip Wear

Spray should be atomized (evenly distributed,
no gaps at edges). Start at low pressure set-
ting, increase pressure a little at a time until you
see a good spray pattern, without tails.

Spray at lowest pressure that atomizes paint.

If maximum sprayer pressure is not enough for
a good spray pattern, tip is too worn. See
Reversible Spray Tip Selection Chart, page 16.

Adjusting Pressure

Align setting indicator on AllControl with function,
page 8.

LOW SPRAY provides the
lowest pressure for
spraying.

HIGH SPRAY increases
pressure.

Unclogging Spray Tip

To avoid fluid splashback:

Tip must be pushed all the way into guard.

Never pull gun trigger when arrow-shaped han-
dle is between SPRAY and UNCLOG positions.

1. To UNCLOG tip obstruction,

engage trigger lock.

2. Point arrow-shaped handle

backward to UNCLOG posi-
tion.

3. Aim gun at piece of scrap or cardboard.

4. Unlock trigger lock. Pull trigger

to clear clog.

5. When obstruction is cleared,

lock trigger lock and rotate
arrow-shaped handle back to
SPRAY position.

Point the arrow-shaped handle on the spray tip for-
ward to SPRAY and backward to UNCLOG
obstructions.

If tails persist when spraying at the highest
pressure, a smaller tip is needed or the
material may need to be thinned.
