SETUP & OPERATION
OPERATING THE AIR-POWERED SPRAY GUN
1.
Always keep the gun at a right angle to the workpiece.
2.
Keep the nozzle about 6" to 12" from the work surface. Grip the gun keeping it
perpendicular with spraying area, then move it in a parallel fashion – keeping it
an even distance from the surface being painted. Stopping sprayer movement in
mid-stroke will cause a build-up of paint and result in runs. Do not fan the gun
from side to side while painting. This will cause a build-up of paint in the centre of
the stroke and an insufficient coating at each end.
3.
Trigger control: Always start the gun moving BEFORE SQUEEZING THE
TRIGGER and release the trigger BEFORE STOPPING GUN MOVEMENT at the
end of the stroke. This procedure will blend each stroke with the next without
showing overlap or unevenness.
4.
The amount of paint being applied can be varied by the speed of the stroke,
distance from the surface and adjustment of the fluid control knob.
5.
Overlap strokes lightly, just enough to obtain an even coat.
NOTE: Two thin coats of paint will yield better results and have less chance of runs
than one heavy layer.
6.
Use a piece of cardboard as a shield to capture the loss of spray paint to the
ends of the piece to paint to protect the other surfaces.

MAINTENANCE & STORAGE
MAINTENANCE
Incomplete cleaning could cause function failures and uneven paint sprays. Always
clean the spray gun immediately after use, to avoid paint dryouts.
1.
Remove any remaining paint by pouring it into another container.
2.
Disassemble the spray gun, making sure to remove the needle before
disassembling the nozzle to avoid damage to the housing of the nozzle closure.
3.
Clean all paint passages and the nozzle. Clean the other components using a
brush soaked in solvent.
4.
Reassemble the spray gun and spray a small quantity of solvent to eliminate any
residues in the paint passages.
WARNING! Never use metal or other objects that could damage the holes in the
nozzle and cap. Never immerse the spray gun completely in solvent. Never use
components or parts that are not manufacturer originals.
