Ball Tip and Packing Cartridge Replacement
CAUTION: If the packing cartridge leaks, it is important to thoroughly clean
the packing cartridge bore in the extension with a compatible
non-conductive solvent to remove any residual coating material. Failure to
do so may result in loss of kV.
CAUTION: Do not overtighten threaded parts. Failure to observe this
caution may result in equipment damage.
The Kinetix spray gun is shipped with the standard gold packing cartridge.
This durable packing cartridge is appropriate for most coating materials.
Use the optional PTFE packing cartridge with harsh chemical solvents such
as MEK.
The only serviceable parts of the packing cartridge are the external O-ring
and back-up ring. If replacing the O-ring and back-up ring does not stop the
packing cartridge from leaking, you must replace the packing cartridge.
The ball tip is not a component of the packing cartridge. You must order the
the ball tip separately.
Preparation
1. Turn off the gun control unit and ground the spray gun electrode to
remove any residual charge.
2. Flush the fluid-delivery system, hoses, and spray gun.
3. Turn off the fluid-delivery system. Relieve system fluid pressures.
4. Point the spray gun into the booth or grounded container and activate it
to relieve any residual pressure.
5. Disconnect the fluid hose from the spray gun. Move the spray gun to a
clean, dry, flat surface.
