Binks Model 102-1700 (43P) AiRleSS SPRAy GUn
3
Your Binks 43P Airless Spray Gun has been thoroughly
tested before leaving the factory. No adjustment is
required prior to its operation other than installing the
nozzle tip.
1. Solvent Hook-up
Hook up solvent line and check to insure proper purg-
ing. Open purge valve and allow solvent to enter the
gun head. Activate valve on-off and observe solvent
spray emitting from front of gun. It is important that
solvent purge be available in case of incorrect resin-
hardener hook-up, reacting fluids, or mixed resins
remaining in gun mix chamber.
2. Gun Hook-up
Remove Items 1, 2, 3, and 5. Connect material lines to
gun. Run system to insure material flows through gun.
Shut gun off and allow system to run to stall. Check
for leaks at all connections.
3. Material flow check
Aim gun into a suitable waste container or place
waste container under front of gun head. Operate for-
mulator and open gun needles until both fluids flow
freely from front of gun head. 1:1 systems should
appear equal in volume. (Off-ratio systems will visibly
be unequal.)
4. calibration
To check for correct proportioning of two fluids the
simplest method is to take two containers of equal
capacity and fill them simultaneously.
Deviation from volumetric ratio of 1:1 can be attributed
to malfunctioning pump(s) or to excessive differences in
viscosity of components.
5. Shut-down
When spraying is discontinued for extended periods
of time such as lunch, overnight or weekends, the fol-
lowing procedures are recommended:
A. Remove items 1, 2, 3, and 4 and place in clean sol-
vent. Pack mixing chamber with petroleum jelly.
B. Leave gun connected to the hoses and formulator
and shut-off fluid supply to the gun, but do not
bleed the pressure.
For long shut-down periods, it is necessary to
purge (“flush”) the system completely (use solvent
recommended by the material supplier). Pump sol-
vent through system until all traces of material are
removed. Pack gun mixing chamber with petro-
leum jelly. To exclude ambient moisture and/or for-
eign matter from hoses and formulator, fill system
with an inert fluid such as a plasticiser (DOTP,
etc.).
6. Gun Ports
The gun head is drilled with bottom material iInlet
ports (1/4 NPT) and solvent port (1/8 NPT).
7. Priming and “Warm-Up”
Heating resins (at the gun head) at start-up can help
assure improved mixing. “Warm-up” may also be
needed after a down-time of duration that would allow
heat loss in hoses to gun.
notE
Purge gun with solvent at end of material flow check.
notE
When a heated system is used, be sure materials are pre-
heated approximately 1 hour prior to calibrating.
notE
if you wish to disconnect fluid hoses, you must first shut
off main air supply to formulator and gun and then bleed
off all fluid material pressure before removing any hoses.
