7. REPLACEMENT PARTS
Caution: If it is necessary to disassemble your airbrush: (1) DO NOT use
pliers. In most cases, no tools are required to disassemble your airbrush
except those provided in the kit. (2) DO NOT over tighten the fluid
nozzle when assembling. Only a slight force is needed with the
included nozzle wrench.
Even though Grex airbrushes are manufactured with precision machin-
ing and high quality materials, several delicate parts require replace-
ment due to normal wear and tear. These include the fluid nozzle, fluid
needle, o-rings, and needle packing.
Fluid Nozzle – Before replacing the fluid nozzle, be sure that the needle
is slightly pulled back away from the fluid nozzle. To do this, remove
the rear handle cap, loosen the needle lock and carefully pull the needle
back. Remove the needle cap and nozzle cap then carefully unscrew the
fluid nozzle using the wrench supplied with your kit. Replace with a
new fluid nozzle and re-assemble the airbrush. Make sure the needle is
set firmly into the fluid nozzle.
Caution: DO NOT over tighten the fluid nozzle when assembling. Only
a slight force is needed with the nozzle wrench.
Note: It is recommended to change the fluid needle at the same time to
ensure even wear.
Fluid Needle – Grex needles are made of precision ground and hardened
stainless steel and will withstand prolonged use. However, because of
their fine tip and long taper, they are easily subject to physical damage.
This is a highly delicate part and any small deformations to the needle
tip will compromise the performance of your airbrush. If the tip is
severely bent, it must be straightened before being removed to prevent
damage to the fluid nozzle.
