SKIN INJECTION HAZARD

High-pressure uid from gun, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.

• Do not point gun at anyone or at any part of the body.

• Do not put your hand over the spray tip.

• Do not stop or deect leaks with your hand, body, glove, or rag.

• Close material shutoff valves and then shut off or disconnect air supply when not spraying.

• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking,

or servicing equipment.

BURN HAZARD

Equipment surfaces and uid that’s heated can become very hot during operation. To avoid severe burns, do not touch hot uid or equipment. Wait until equipment/uid has cooled completely.

FIRE AND EXPLOSION HAZARD

Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent re

and explosion:

• Use equipment only in well ventilated area.

• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop

cloths (potential static arc).

• Keep work area free of debris, including solvent, rags and gasoline.

• Do not plug or unplug power cords, or turn power or light switches on or off when ammable fumes are

present.

• Ground all equipment in the work area.

• Use only grounded hoses.

• Hold gun rmly to side of grounded pail when triggering into pail.

• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until

• Keep a working re extinguisher in the work area.

Warnings

WARNING

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• Do not operate the unit when fatigued or under the inuence of drugs or alcohol.

• Do not exceed the maximum working pressure or temperature rating of the lowest rated system compo-

nent. See Technical Data in all equipment manuals.

• Use uids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read uid and solvent manufacturer’s warnings. For complete information about

your material, request MSDS forms from distributor or retailer.

• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturer’s replacement parts only.

• Do not alter or modify equipment.

• Use equipment only for its intended purpose. Call your distributor for information.

• Route hoses and cables away from trafc areas, sharp edges, moving parts, and hot surfaces.

• Do not kink or over bend hoses or use hoses to pull equipment.

• Keep children and animals away from work area.

• Comply with all applicable safety regulations.

PRESSURIZED ALUMINUM PARTS HAZARD

Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon

solvents or uids containing such solvents in pressurized aluminum equipment. Such

use can cause serious chemical reaction and equipment rupture, and result in death,

serious injury, and property damage.

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 specic hazards and

precautions related to isocyanates. Prevent inhalation of isocyanate mists, vapors, and

atomized particulates by providing sufcient ventila-

tion in the work area. If sufcient 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 specically 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 contaminated 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.

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 hous-

ing, side seal assembly, check valve cartridge, and mix chamber are marked on the A side.

Changing Materials

• When changing materials, ush the equipment multiple 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 orices are aligned with the

orices in both, the side block seal and check valve assem-

blies.

The proper alignment of the orices 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 assem-

blies 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

orices 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 maxi-

mum 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 specication 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.

Section 3 - General Information: Maintenance

WARNING

Before attempting to perform any maintenance on this

gun,relieve All Fluid and Air Pressures!

2. Check the material valves (Part No. 256459, 256460)

for any leaks:

• To relieve uid and air pressures:

• Turn OFF all air supplies at system except gun trigger

air.

• Trigger the gun until all uid pressures have been

relieved.

• Turn OFF the gun trigger air at the system.

• Turn proportioner off.

• Trigger the gun until all trigger air pressure has

been relieved.

Perform Gun maintenance as follows:

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.

• 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 red and blue knobs and turning 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.

3. Check side blocks

• 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.

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 (Part No. 117773) in each side of the gun

front housing and on the side block seals.

r_gcp3ra_313266_1_6e

DO NOT open the air valve because this will purge grease from the Gun. The grease should be allowed

to remain in the gun overnight.

Section 3 - General Information: Maintenance

Daily Shutdown

For experienced users

Once you have used the gun with a product and system,

and you have become comfortable with techniques on how all the variables are affecting your operations and maintenance requirements, Daily, Weekly, and Monthly Maintenance requirements can be addressed specic to your operation.

1. Clean the gun using a brush and an appropriate clean

solvent.

2. Inspect the side block seals making certain they are

clean and free of scratches, nicks or foreign material.

Clean and replace as required.

3. Remove, clean or replace the lter screen.

4. Maintain a reasonable stock level of “wear” items such

as seals and o-rings. (see Service & Repair Parts Kits listed in Parts & Illustrations section.)

5. Grease gun daily to prevent 2 component curing and

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.

6. Inspect all threads for wear or damage and replace as

required.

7. Tighten all threaded parts securely, but not excessively,

upon assembly.

8. Lightly lubricate all o-rings and threads with

grease (Part No. 118665).

9. Check all springs for resilience. They should return

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. There is a set screw

that determines how far the piston will travel before it stops.

To determine if the throw is correct:

1. Follow the pressure relief procedure on page 16 and

disconnect material hoses from the gun.

2. Turn the material ball valves to the OFF position.

5. Remove one of the side block seal housings, from side

block. Leave the seal (34) in housing and rinse with

suitable solvent.

6. Place the side seal housing in the gun head so the face

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!

7. Turn the gun trigger air supply on, then trigger the gun.

3. Verify that the piston lock cap has been tightened and

fully threaded into the gun.

4. Remove the side blocks.

r_gcp3ra_313266_1_6e

The purge air will not shut off with the side block

removed.

8. If the impingement port is not fully visible through the

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.

9. If the impingement port on the mix chamber is fully

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.

10. Reassemble the gun.

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.
