Hints For Good Spraying Results - Craftsman 919.716100 Owner's Manual

• Hold the gun perpendicular to the surface, 6" to 8"
distance.
• Follow contour.
• Overlap each stroke 50%.
• Ends are feathered by triggering. That is, begin stroke
before pulling trigger and releasing just before ending
the stroke.
• Spray edges and corners first. This will reduce over-
spray while providing good coverage on corners.
• Don't arc strokes, move the gun parallel to work.
PROBLEM
Heavy top or bottom pattern.
Heavy right or left side
pattern.
Heavy center pattern.
Split spray pattern.
Jerky or fluttering spray.
GENERAL INFORMATION

HINTS FOR GOOD SPRAYING RESULTS

TROUBLESHOOTING GUIDE
CAUSE
Material build-up on air cap or fluid
tip. Partially plugged horn holes,
center holes or fluid tip hole.
Too much material.
Material too thick.
Not enough material.
Insufficient material.
Gun with cup tipped at excessive
angle.
Obstructed fluid passage or hose.
Loose fluid tip or damaged tip seat.
(Most common cause.)
Loose or cracked fluid tube in cup
or pressure tank.
Too heavy fluid for suction feed.
Dry or worn packing or loose
packing nut.
Your pattern should normally be shaped like this.
If not, see Troubleshooting Guide.
CORRECTION
Determine where material build-up is by inverting
cap and test spraying. If pattern shape stays in
same position, the condition is caused by material
build-up on fluid tip. If pattern changes with cap
movement, the condition is in the air cap.
Soak cap or tip in suitable solvent and wipe clean.
To clean orifices use a broom straw or toothpick.
Never use a wire or hard instrument. This damags
holes and distorts its spray pattern.
Reduce fluid flow or increase air pressure.
Thin material.
Reduce air pressure or increase fluid flow.
Fill material container.
Do not tip excessively or rotate fluid tube.
Clean.
Tighten or replace.
Tighten or replace.
Thin material or change to pressure feed.
Lubricate or replace. Tighten.
