Spray
NOTE: If using an NXT air motor with DataTrak, see
DataTrak Operation, page 33, for instructions on using
the DataTrak counter/totalizer.
Prior to production use, spray onto a clean piece of
paper until all system settings are adjusted to optimize
the spray pattern.
Perform this full procedure whenever the gun has been
unused for an extended period of time, such as over-
night. After performing this full procedure, spraying can
be performed intermittently as desired by simply pulling
the trigger and utilizing the trigger lock to prevent acci-
dental triggering.
1. If this is the first time starting up the system, if fluid
lines have been disconnected, if the fluid supply line
has been removed from the supply container, or if
either pump has been run dry, perform Prime pro-
cedure on page 27.
2. Turn the main air supply ball valve to the closed
position.
3. Turn the main air supply pressure regulator fully
counterclockwise.
4. Turn the resin pump pressure relief/recirculation
valve to the dispense position.
5. Turn the catalyst pump pressure relief/recirculation
valve to the dispense position. See F
IG
. 27.
6. Bring catalyst pump fluid outlet line to dispensing
pressure (see F
IG
. 27):
a. Remove pin connecting upper catalyst pump
arm to air motor rod then manually stroke the
pump until the catalyst pressure gauge shows:
External mix systems: 30-40 psi
(0.21-0.28 MPa, 2.1-2.8 bar).
Internal mix systems: 300-400psi (2.1-2.8 MPa,
21-28 bar).
b. Insert pin to connect upper catalyst pump arm
to air motor.
