serious injury, and property damage.
4
Warnings
Isocyanate Hazard
Spraying materials containing isocyanates creates
potentially harmful mists, vapors, and atomized
particulates.
Read material manufacturer’s warnings and
material MSDS to know specic hazards and
precautions related to isocyanates.
Prevent inhalation of isocyanate mists, vapors, and
atomized particulates by providing sufcient ventilation in the work area. If sufcient ventilation is not
available, a supplied-air respirator is required for
everyone in the work area.
To prevent contact with isocyanates, appropriate
personal protective equipment, including chemically
impermeable gloves, boots, aprons, and goggles, is
also required for everyone in the work area.
To prevent exposing ISO to moisture:
Always use a sealed container with a desiccant dryer •
in the vent, or a nitrogen atmosphere. Never store ISO
in an open container.
Keep the ISO lube pump reservoir lled with Graco •
Throat Seal Liquid (TSL), Part 206995. The lubricant
creates a barrier between the ISO and the atmosphere.
Use moisture-proof hoses specically designed for •
ISO, such as those supplied with your system.
Never use reclaimed solvents, which may contain •
moisture. Always keep solvent containers closed when
not in use.
Never use solvent on one side if it has been contami-•
nated from the other side.
Always park pumps when you shutdown.•
Always lubricate threaded parts with Part 217374 ISO •
pump oil or grease when reassembling.
Moisture Sensitivity of
Isocyanates
Isocyanates (ISO) are catalysts used in two component
foam and polyurea coatings. ISO will react with moisture
(such as humidity) to form small, hard, abrasive crystals,
which become suspended in the uid. Eventually a lm will
form on the surface and the ISO will begin to gel, increasing in viscosity. If used, this partially cured ISO will reduce
performance and the life of all wetted parts.
The amount of lm formation and rate of crystal-
lization varies depending on the blend of ISO,
the humidity, and the temperature.
5
Warnings
Material Self-ignition
Some materials may become self-igniting if applied to
thickly. Read material manufacturer’s warnings and
material MSDS.
Keep Components A and B
Separate
CAUTION
To prevent cross-contamination of the equipment’s wet-
ted parts, never interchange component A (isocyanate)
and component B (resin) parts. The gun is shipped with
the A side on the left. The uid manifold, uid housing, side seal assembly, check valve cartridge, and mix
chamber are marked on the A side.
Changing Materials
When changing materials, ush the equipment mul-•
tiple times to ensure it is thoroughly clean.
Always clean the uid inlet strainers after ushing.•
Check with your material manufacturer for chemical •
compatibility.
Most materials use ISO on the A side, but some use •
ISO on the B side.
Epoxies often have amines on the B (hardener) side. •
Polyureas often have amines on the B (resin) side.
Foam Resins with 245 fa
Blowing Agents
New foam blowing agents will froth at temperatures above
90°F (33 °C) when not under pressure, especially if agitated. To reduce frothing, minimize preheating in a circulation
system.

Section 1 - Installation: Equipment Assembly
How The Gun Works
The trigger actuates a small valve in the gun handle
that controls the ow of air into the piston assembly.
When the trigger is pulled, air ows through the valve to
the front of the piston. Air pressure forces the piston
towards the rear of the gun, simultaneously closing off the
purge air and moving the mixing chamber to a position
where the mixing chamber orices are aligned with the
orices in both, the side block seal and check valve assem-
blies.
The proper alignment of the orices is determined by
the setting of the adjustment nut, located on the pis-
ton lock assembly.. This adjustment nut determines
the length of travel of the air piston and has been
preset at the factory and should not require adjustment. (SEE MAINTENANCE SECTION)
The two uids (isocyanate and polyol) then ow through
the material shut-off valves, seal, and check valve assemblies and into the mixing chamber. The two uids impinge
against one another and exit the mixing chamber in a swirling, conical spray pattern.
Piston Lock
Engage piston lock whenever you stop spraying, to avoid
accidental triggering.
Always use piston lock in conjunction with uid ball valves
to avoid accidental triggering.
WARNING
Read warnings, page 3.
To engage Piston lock: push knob in and turn clockwise.
If engaged, gun will not actuate.
r_257826_313266_1_2b
To disengage piston lock: push knob in and turn coun-
terclockwise until it pops out. There will be a gap between
knob and gun body.
When the trigger is released, the mixing chamber returns
to its original position and purge air ows into the mixing
chamber housing. The front tip o-ring keeps air purge
inside the gun head, which forces all of the air through the
orices in the mixing chamber creating a complete, total
and constant purge.
This purge air continues to ow through the mixing cham-
ber until the air valve has shut-off all air to the gun; or until
the trigger is pulled again.
r_257826_313266_1_1b
See page 19 for piston lock adjustment or installation.
Loss of Air Pressure
In event of loss of air pressure, gun will continue to spray.
To shut off gun, do one of the following:
Push in piston lock, see • Engage piston lock.
Close ball valves A and B.•

Operating Requirements
• 8 - 10 CFM at 90 -110 psi (0.62-0.76 MPa,
6.2-7.6 bar)
• MAXIMUM Static Fluid Pressure - 3200 psi
(22 MPa, 220 bar)
WARNING
If purge air is to be turned OFF, BOTH MATERIAL SHUTOFF VALVES MUST BE TURNED TO THEIR “OFF” POSITION BEFORE TURNING “OFF” THE PURGE AIR !
Failure to follow this procedure will possibly result in the gun
head becoming encased with mixed product.
For proper purging following use, the air switch must be left
OPEN for at least 15 SECONDS after the trigger has been
released.
The ow of material into the mixing chamber is controlled
by the ON or OFF position of the two material shut-off
valves.
Both material shut-off valves must be FULLY OPEN
and piston lock DISENGAGED during dispens-
ing and must be FULLY CLOSED and piston lock
ENGAGED during service or extended shut-down
periods.
WARNING
BOTH MATERIAL SHUT-OFF VALVES MUST BE
TURNED TO THEIR “OFF” POSITION AND ALL FLUID
PRESSURE RELIEVED BEFORE REMOVING SIDE-
BLOCK SCREWS!
WARNING
The GlasCraft Probler P2 Elite Gun is designed and manu-
factured to operate at a maximum static uid pressure not
to exceed 3200 psi (22 MPa, 220 bar). When attached to
a GlasCraft proportioning system, this pressure will not be
exceeded. However, if the GlasCraft Probler P2 Elite gun is
installed on any other manufacturer’s self-designed equipment, great care must be taken to ensure that the maximum static uid pressure not be exceeded.
If the gun is being used for short periods of spraying,
GlasCraft recommends that the purge air be left ON.
Failure to follow this procedure will possibly result in the
gun head becoming encased with mixed product.
ON OFF
Refer to system manuals for start-up and
shut-down procedures.

Section 2 - Operation: Start-Up Instructions
Spray Technique
Always operate safely and follow all safety procedures
outlined.
To achieve the optimum spray pattern for each application,
the appropriate mixing chambers are available in seven
sizes.
The standard mixing chamber supplied with your gun will
be adequate for all but the smallest and largest applications.
Foam rise and cure times will vary according to the material and substrate temperature. Higher material or substrate
temperature will increase rise and cure times; lower material or substrate temperatures will decrease rise and cure
times. Consult your chemical manufacturer’s data specication sheets for their recommended spray temperatures.
Under most circumstances, both components will be used
at identical temperatures.
Higher pressures and temperatures may be used to
increase material break-up, improve mixing and speed
rise times. With hose lengths over 50 ft.(15.25 m), or
when material viscosities are high, higher material
pump pressures may be necessary.
The gun air valve MUST BE OPENED prior to spraying
to provide air for trigger operation and purge air when
the trigger is released.
When spraying, the gun trigger may be depressed con-
tinuously, or triggered at the end of each stroke. A
smooth, even layer is best achieved by moving the
gun back and forth in a slow, even motion, overlapping
the previous pass about 50 to 75 percent. DO NOT
SPRAY OVER RISING FOAM! The ideal gun-to-surface
distance is about 18 to 24 inches. Be sure to point the
gun directly at the surface to be sprayed. Spraying at
an angle to the surface will cause the foam to be rough
and will generate overspray.

been relieved.
Perform Gun maintenance as follows:
1. Check for leaking seals (41).
Engage piston lock.•
Turn OFF the gun incoming air by closing gun air •
valve.
Turn ON the material ball valves.•
Check the material valves, p/n GC2337 for any leaks:2.
Turn OFF both material valves.•
Disengage piston lock.•
Trigger the gun several times.•
Wait approximately 10-20 seconds.•
Trigger the gun several times. •
If additional material is purged, the material valves •
are leaking.
Correct the leaks by taking off black knobs and turn •
ing packing 1/8 in. to 1/4 in. turns at a time until the
leak has stopped. Re-check.
Wait approximately 10 - 20 seconds, then turn ON •
the incoming air by opening gun air valve.
Repeat two or three times.•
If any material has been purged from the gun, the •
seals (41) or o-ring (42) are leaking.
Correct leaks by replacing the seals or o-rings and •
re-checking.
Check side blocks3.
Turn OFF the air valve. •
WARNING
Before removing the side blocks make certain that both material valves are in the OFF position. Then trigger the gun
several times to relieve pressure.
If the material valves are on when the side blocks are
removed the gun will quickly become encased in urethane!
WARNING
Point gun side blocks down, away from all personnel.
Existing uid pressures could cause material to exit the
side blocks with considerable force.
16
Section 3 - General Information: Maintenance
Take the side blocks off by removing screws.•
r_gcp3ra_313266_1_6e
Examine the sides of the mixing chamber for scratch •
es and/or material build-up. Carefully, without
scratching the seal surfaces (sides), remove any
accumulated material. Solvent can be used to wash
accumulated material off of chamber, side blocks, etc.
Keep the gun chamber tilted toward the ground so
that solvent does not run back into gun. Certain
solvents will attack o-rings on chamber shaft causing
swelling and deterioration of o-rings.
Use correct size drill bit to clean out the mixing •
chamber exit passage. Use correct size drill bit to
clean the inlet side holes of the mixing chamber tak-
ing care not to scratch the mixing chamber’s polished
surfaces. (Refer to the drill chart in this manual.)
Re-assemble the side blocks and tighten the screws. •
Grease should appear at the tip of the mixing cham ber.
Place generous amounts of high quality, white lithium •
grease in each side of the gun front housing and on
the side block seals.

Routine Care
WARNING
Before attempting to perform any maintenance on this gun
OR before removing side blocks, make certain that both
gun material valves are in the fully OFF positions and trigger several times to depressurize uid in gun!
If the material valves are on when side blocks are removed,
the gun will quickly become encased in urethane!
It is recommended that the following service be performed
on a daily basis.
1.
Clean the gun using a brush and an appropriate clean
solvent.
Inspect the side block seals making certain they are 2.
clean and free of scratches, nicks or foreign material.

Section 3 - General Information: Maintenance
Piston Lock Adjustment and Installation
Procedure
The P2 gun piston throw is factory set and as a rule, should
not require adjustment. The piston throw refers to how far
back the air piston will travel when the gun is triggered.
Proper throw adjustment will align the mixing chamber side
ports with the side block seal thru port. There is a set screw
that determines how far the piston will travel before it stops.
To determine if the throw is correct:
Follow the
1. pressure relief procedure on page 16 and
disconnect material hoses from the gun.
Turn the material ball valves to the OFF position.2.
Remove one of the side block seal housings, from side 5.
block. Leave the seal (34) in housing and rinse with
suitable solvent.
Place the side seal housing in the gun head so the face 6.
of the seal sets against the mix chamber.
WARNING
If the material valves are on when side blocks are
removed, the gun will quickly become encased in ure-
thane!
Turn the gun trigger air supply on, then trigger the gun.7.
Verify that the piston lock cap has been tightened and 3.
fully threaded into the gun.
Remove the side blocks.4.
r_gcp3ra_313266_1_6e
The purge air will not shut off with the side block
removed.
If the impingement port is not fully visible through the 8.
side seal housing turn the trigger-air off and trigger the
gun to relieve pressure. Use a 9/16 in. open-end
wrench to adjust the adjustment nut in the appropriate
direction. Repeat steps 7 and 8 until it is
adjusted properly.
If the impingement port on the mix chamber is fully 9.
visible through the side seal housing (either on
center or slightly forward), the piston lock adjustment
nut is properly aligned.
Non-permanent thread locker can be applied to the
adjustment nut if necessary.
Reassemble the gun.10.
Before each use: Verify that the piston lock assembly is
installed and working properly.
Engage piston lock.•
Pressurize the system to working pressure.•
Open material ball valves.•
Point the gun in a safe direction and trigger gun. No •
material should ow from gun tip.
DO NOT USE IF IT IS NOT WORKING PROPERLY.•
