INTRODUCTION:
The SI Airbrush is simple in design and operation. Ideal for Hobbyists and
Crafters that are just learning to use an Airbrush. Available off the shelf as size
#3 with size #1 and #5 components available for your assembly. PTFE
Packings.
OPERATING INSTRUCTIONS:
Adjustments in the flow of color are made by turning the Needle Chuck
(#9) in to decrease, or out for increased flow. To spray, press the Trigger (#6).
To disassemble, loosen the Needle Locknut (#10) by holding the Needle Chuck
(#9) firmly so it will not turn. Unscrew the Needle Chuck from the Handle (#7)
and remove the Handle. Now carefully remove the Needle (#16) and then the
Finger Button Assembly. The Head (#2) and Tip (#3) may now be removed.
Reassembly should always be done with care, especially when reinserting the
Needle. Reverse the procedure used for disassembly. After the Needle has
been gently pushed forward into the tip, assemble the Needle Chuck (#9) and
screw it in firmly. Hold the Needle Chuck while screwing the Needle Locknut
(#10) down to lock the needle. Caution should always be used when reinserting
the Needle - too much pressure can damage the tip.
ADJUSTING OR REPLACING WORN PACKING WASHER:
1. If PTFE Packing & Packing Nut (#5) become worn or loose they must be tightened or
replaced.
2. When replacing your PTFE Packing press Packing into the Packing Nut (#5).
Use a small screwdriver to tighten packing nut into shell until it is tight then
back out one-half turn, may vary.
3. Now insert Trigger and then Needle - you should feel a slight resistance to the
needle as it goes through packing. If too loose or too tight adjust the Packing
Nut with screwdriver until you feel some slight resistance. Replace the Needle
Chuck and the Needle Locknut.
