Gun Nozzle Replacement & Maintenance
Revision Date / Version: 2/13/2014 - 3
The Swing gun uses a gun nozzle tip for grabbing stones from the
hoppers and exchanging them to the
lower gun to be placed onto the transfer sheet. Over time, dirt
and oil will make its way into the nozzle
assembly and make it stick and lessen the spring reaction when
the nozzle tip is pressed in. When this
happens Maintenance will need to be done to clean the Gun nozzle
to increase the spring reaction to as
new condition.
Other issues is the hole of the nozzle tip which provides the
vacuum to lift a stone will become worn
away to a point air will be able to wrap around the smaller SS06
stones and the stones will start to shift
on the nozzle tip making collision with other already placed
stones and making the stone being placed to
flip upside down or on its side. In this situation replacing the
Gun nozzle is recommended
Gun Nozzle Maintenance:
Tools Needed:
1) 8mm Combination Wrench (Supplied with the new machines) 2)
Paper towel 3) 3 in 1 oil or any machine oil 4) 70% Isopropyl
Alcohol The gun nozzle comes in 4 pieces (See Image Below). You
have the nozzle tip, the spring, the housing, and the collar screw
which holds it all together. Be sure to work over a table cause
these pieces especially the collar are very small and get lost
easily. Below are some illustrations of how to take it apart and
you will want to use 3 in 1 oil to lubricate the O ring on the gun
nozzle and lightly oil the housings interior. I use a cue tip with
some oil on it and wipe inside the housing. You will need a vice
grip and another pair of pliers. Adjust the vice grip to just hold
the collar screw (Be careful not to crush it as the nozzle tip
shaft is hollow and can crush with too much pressure, you want to
adjust the vice grip around the collar screw to help you unscrew it
from the nozzle tip shaft. With your second pair of pliers, hold
the nozzles tip and with the vice grip. Unscrew the collar screw
from the nozzle tip shaft and you can then disassemble the gun
nozzle.

The way you put it together is the spring goes onto the Nozzle
tip shaft, and then it is inserted into the Housing and is secured
by screwing the collar bolt onto the end.
Gun Nozzle Tip Replacement: To Replace Gun Nozzle assembly, use
the supplied 8mm combination wrench to remove the gun nozzle from
the Swing gun, then replace with new one ensuring that it is snug
but do not over tighten as it could strip the threading inside the
Gun Rod.
