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.
