TechnicalSpecifications
• Model: 8059851
• Air pressure: 30-80 PSI
• Nozzle diameter: 1.4 mm
• Type of feed: Gravity
• Air consumption: 5 CFM
• Pattern width: 7-1/2" (190 mm)
• Paint capacity: 3.5 oz
Operation
1. Suggested air pressure is 30-80 PSI
2. Recommended paint viscosity differs according to paint properties and
painting conditions.
3. Use the lowest possible fluid output that produces an adequate paint
coverage. Finer atomization leads to a better finish.
4. Maintain a distance of 6-8" from the gun to the workpiece.
5. The gun should be held so that it is perpendicular to the surface of the
workpiece at all times. Move the gun in a straight and horizontal line.
Arcing the gun results in an uneven paint finish.

Maintenance
1. Pour remaining paint into another container and then clean paint
passage and air cap. Spray a small amount of thinner to clean paint
passages. Incomplete cleaning will cause adverse pattern shapes and
particles to appear on your work. Promptly clean components after use.
2. Clean other sections with a brush and cloth soaked with thinner.
3. Clean paint passages fully before disassembly.
4. Remove the fluid nozzle after removing the fluid needle set or while
keeping fluid needle pulled in order to protect seat section.
5. While keeping fluid needle set inserted, tighten fluid needle packing
set by hand. Then tighten gradually with a wrench. Adjust the packing
set while pulling the trigger and watching the movement of the fluid
needle set since over-tightening will strip the thread, causing leakage.
6. Turn the spread adjustment knob counterclockwise to fully open it,
then tighten the spread adjustment guide into the gun body.

Troubleshooting
Symptom
Intermittent spray • Presence of air in the
paint circuit
• Material residue in the
holes obstructs the pas-
sage of material
• The nozzle is dirty or
malfunctioning
• The atomization cap is
dirty or damaged
• Submerge the head in solvent
• Clean and open all closed
holes with a jet of compressed
air or a toothpick.
• Do not use pointed metal
objects, or you may deform
the hole of the head part.
• Material builds up on the
outside of fluid nozzle tip
or center hole or partially
clogged nozzle orifice.
• Loose fluid nozzle
• Clean the head and the nozzle
• Make sure that the centering
between the two is precise
• Check that the tip of the pin is
not ruined
• Replace the nozzle and the
head
• Atomization of air
pressure is too high
• Material too thin
• Reduce the quantity of air and
increase the flow of paint.
• The flow of paint is
greater than the pressure
and quantity of air
supplied.
• Fluid passage is clogged
with dirt
• Air holes in the cover are
blocked
• Fluid needle stroke is too
short
• Clean the head and the nozzle
• Make sure that the paint is not
too dense and dilute if
necessary
• Remove obstructions
• Adjust fluid needle stroke
• Tighten the nozzle using the
wrench provided.
• Make sure that the tank is not
empty.
• Check that the connecting hole
is not obstructed.
• Tighten the gland screw or
replace the gasket if worn
