GENERAL CLEANING
To clean the Gun after each use, empty all paint from the Cup. Use a
solvent-soaked rag to clean the residue in the Cup. Then, spray some
clean solvent through the Gun into a clean rag (to avoid filling the room
with unnecessary spray) or a bucket. Repeat until the inside of the
fluid passages in the Gun, Metal Fluid Tube etc. are clean. Use the
wet rag to wipe off the Air Cap and tip of the Fluid Nozzle. The Air Cap
can be soaked in thinner.
If this type of cleaning is done while the paint is still wet in the Gun, it
should be all that is necessary to keep the Gun clean enough for next
time. Do not leave liquids in the Cup overnight or for long periods.
Do not restrict the Fluid Nozzle when cleaning (by putting your finger
over the Nozzle orifice) - this will drive thinned paint up the pressure
tube and into the spray gun which is undesirable.
PLEASE DO NOT USE A WIRE BRUSH OR ANYTHING METAL TO
CLEAN THE GUN OR CUP AS THIS WILL CAUSE DAMAGE.
DO NOT disassemble the Cup Assembly - Threads in your cup
have been sealed at the factory to prevent leakage under
pressure.
The standard 1 quart (1000cc) Cup can be used with most coatings
(including water-based). Also available as an accessory is our 2041T
Teflon-coated Cup. Four sizes of Gravity Cups are also available.
CAUTION: Never soak the complete Spray Gun in solvent as this
removes the grease from the parts and distributes thinned paints
throughout the air passages. It could also damage internal parts such
as the Spindle Valve or Valve Seals. It may sometimes be necessary
to soak the Air Cap, Nozzle, Needle, Air Diffuser and Air Divider. You
may soak only the metal parts in solvent and clean with the soft
bristle Cleaning Brush 9045. To reassemble, first oil or grease all
moving and threaded parts.
CAUTION: Do not lay the Gun down on its side with liquid mate-
rial in it. When not in use the Cup Lid should not be clamped
down hard as this will cause the Gasket to flatten out.
SPRAYGUN PROBLEMS
NO PAINT (OR VERY LITTLE PAINT)
The air passing through the Pressure Tube 2024 to pressurize the Cup
is blocked. This means that either the Tube itself, the Check Valve, or
one of the two Nipples are blocked. A pipe cleaner can be used for
cleaning the hole in the Nipple.
• Pressurizing Tube and/or Nipples are blocked - COMMON
• The Cup is not tightened down sufficiently or the Cup Lid
Gasket is worn and leaking air
• The Cup is empty
• The metal Fluid Tube is blocked with paint - RARE
• The Fluid Coupler is blocked with paint - RARE
UNEVEN SPRAY PATTERN
One of the holes in the Air Cap may be blocked. Or, the paint could be
dirty and is partially blocking the Fluid Nozzle. Remove the Air Cap
and clean by soaking in solvent and using the soft Bristle Brush or a
rag. NEVER use metal objects to clean holes in the Air Cap.
LEAKAGE
If paint material comes out of the Fluid Nozzle without pulling the
Trigger...
• The Needle is not seating in the Fluid Nozzle properly
• The Needle Packing may be too tight preventing the
Needle from moving - See Page 14 Needle Packing
• Foreign matter trapped between Needle and Fluid Nozzle
• The Needle or Fluid Nozzle could be damaged or worn
• Loose Fluid Nozzle
• Wrong Fluid Nozzle size installed
CUP LEAKS
• Oil above and below the Lever to smooth the Lever action
• Change Gasket/Diaphragm
• Leak around Nipple - use Loctite to seal
• Leak around Side Pins - use Loctite to seal
• Leak through Lid - remove Nut under Lid - use Loctite
