Handpiece/Nozzle Tips
•
The nozzle tips are made of tungsten carbide or sapphire which crack easily, so they
must be handled and stored with care.
•
Nozzle tips sometimes wear, enlarging the side wall. An air stream with lack of
definition signals that the nozzle is worn and the tip should be replaced. To do this
unscrew the nozzle from the handpiece and screw in a new one. Make certain that the
new nozzle is fastened securely to avoid powder leaks. Avoid cross threading.
•
The Red, Violet and Gold SST handpiece/nozzle assemblies do not come apart.
•
Replace a handpiece by disconnecting it from the air hose and replacing it with a new
one.
On occasion the nozzle of the handpiece will clog due to excessive flow of powder.
Unclog the nozzle as follows:
1) Remove the handpiece from the air hose and turn the Beam Intensity control knob completely
counterclockwise.
2) Hold the tip end of the nozzle tight against the air hose connector.
3) Turn the unit on end and actuate the Footswitch, supplying air to reverse flush the clogged tip.
NOTE: This should be done in an exhaust chamber.
Handpiece/nozzles for special applications are available. Consult your Welch Allyn / Kreativ
sales representative for information.
Pinch Valve Tube Replacement:
The rubber pinch valve tube wears and will eventually leak.
NOTE: The Pinch Valve body does NOT have to be removed from the unit for tube replacement.
