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.
Material Self-Ignition
Some materials may become self-igniting if applied
too thickly. Read material manufacturer’s warnings
and material MSDS.
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
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.
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.
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.

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 assemblies.
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.
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, forcing all of the air through the orices
in the mixing chamber, for a complete, total and constant
purge.
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.
This purge air continues to ow through the mixing cham-
ber until the air switch is pulled up to 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.•

Pre operation Checklist
Check that all ttings are tight and air regulators are
turned to “zero pressure”.
WARNING
If purge air is to be turned OFF, BOTH MATERIAL SHUTOFF VALVES, MUST BE TURNED TO THEIR “OFF” POSITION AND PISTON-LOCK ENGAGED BEFORE TURNING
“OFF” THE PURGE AIR !
Failure to follow this procedure will possibly result in the
gun head becoming encased with mixed product.
WARNING
Do not place any part of the body in the path of the material
spray.
Do not point the gun at or near other personnel.
Do not look into the mixing chamber orice at anytime.
Because of the hazardous materials used in this equip-
ment, it is recommended that the operator use an air mask,
goggles, protective clothing, and other safety equipment
as prescribed by current regulations, recommendations of
the chemical suppliers, and the laws in the area where the
equipment is being used.
Operating Requirements
• 8-10 CFM at 90-110 psi (0.62-0.76 MPa,
6.2-7.6 bar)
• MAXIMUM Static Fluid Pressure - 3500 psi (24.1
MPa, 241 bar)
WARNING
The GlasCraft Probler P2 Gun is designed and manufac-
tured to operate at a maximum static uid pressure not to
exceed 3500 psi (24.1 MPa, 241 bar). When attached to
a GlasCraft proportioning system, this pressure will not
be exceeded. However, if the GlasCraft Probler P2 Gun is
installed on any other manufacturer’s self-designed equip-
ment, great care must be taken to ensure that the maxi-
mum static uid pressure not be exceeded.
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!!
Failure to follow this procedure will possibly result in the
gun head becoming encased with mixed product.
If the gun is being used for short periods of spraying,
GlasCraft recommends that the purge air be left ON.
ti19823a

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
spray 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., or when mater-
ial viscosities are high, higher material pump pressures
may be necessary.
The gun air switch assembly MUST BE OPENED (down
position) 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.

side blocks with considerable force.
15
Section 3 - General Information: Maintenance
Take the side blocks off by removing screws.•
ti21611a
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.

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.
Read each procedure entirely before beginning and 1.
refer to the illustrations as needed.
Flush and clean all chambers and passages as they 2.
become accessible.
Clean all parts before assembly.3.
Replace all o-rings and seals with new parts from the 4.
appropriate kit.
Inspect all parts for wear or damage and replace as re- 5.
quired with new genuine GlasCraft replacement parts
from your authorized GlasCraft distributor.
Inspect all threads for wear or damage and replace as 6.
required.
Tighten all threaded parts securely, but not excessively, 7.
upon assembly.
Clean the gun using a brush and an appropriate clean 1.
solvent.
Inspect the side block seals making certain they are 2.
clean and free of scratches, nicks or foreign material.
Clean and replace as required.
Remove, clean or replace the lter screen.3.
Maintain a reasonable stock level of “wear” items such 4.
as seals and o-rings. (see Service & Repair Parts Kits
listed in Parts & Illustrations section.)
Grease gun daily to prevent 2 component curing and 5.
keep uid passages clean. Purge air carries grease
mist through air chamber and impingement ports then
out the mix chamber nozzle, coating all surfaces. Use
Part No. 117773 grease.
Lightly lubricate all o-rings and threads with 8.
grease (Part No. 118665).
Check all springs for resilience. They should return 9.
quickly to their original (new) length.

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.
Determine if the piston throw is correct:
Follow the 1. pressure relief procedure on page 15 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.
ti21614a
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 urethane!
Verify that the piston lock cap has been tightened and 3.
fully threaded into the gun.
Remove the side blocks.4.
ti19825a
ti21612a
Turn the gun trigger air supply on , then trigger the gun.7.
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.•
