Introduction

Manual and pneumatic 2K dispense guns with built-in aluminum retainers are used for the dispensing of lled
Film-Pak® collapsible cartridges. Manual guns are available in two thrust ratios for the dispensing of thicker
materials. Pneumatic guns include an adjustable heavy duty aluminum air regulator and an air dump valve which
stops material ow instantly.

Both manual and pneumatic guns include a spring-loaded latch system with a swing plate to securely hold
Film-Pak cartridges, a uid level indicator, and built-in aluminum cartridge retainers.

Safety

2K dispense guns are designed for heavy duty cycles over extended operating periods. Because they are
powered by compressed air, operator fatigue is minimal, but users must be aware that compressed air can be
dangerous when used incorrectly.

CAUTION

Use caution when operating a dispense gun powered by compressed air. When used incorrectly, compressed air
can cause whipping, impact, material ejection, or other related injuries.

General

• Read and understand these operating instructions before using a dispense gun.

• Compressed air can be dangerous when used incorrectly.

• Modications made by the user to the dispense gun will void the warranty and can cause personal injury.

Always:

• Use protective eye and ear equipment when operating a dispense gun.

• Wear a face mask or respirator when operating a dispense gun.

• Test the forward / reverse function before loading a cartridge.

• Disconnect the air supply before starting any service tasks.

• Ensure that cartridges are properly loaded (refer to the correct cartridge loading procedure in these instructions

for your dispense gun).

• Use a new static mixer.

• Read the material manufacturer’s instructions carefully.

• Ensure that no cross-contamination of the content of the two cartridges has occurred; material can cure in one

of the sides.

• Keep hands and ngers clear of moving parts during operation.

Do not:

• Connect the dispense gun to an air supply that can exceed 8bar (115psi).

• Immerse the dispense gun in solvent.

• Operate the dispense gun with loose, broken, or missing parts. They could come loose unexpectedly and

create a whipping / impact hazard.

• Carry the dispense gun by the air hose.

• Use damaged cartridges or the wrong type of cartridge.

• Point the dispense gun at another person.

• Disassemble the handle and adjust the safety valve inside.

• Use a static mixer that contains cured material.

• Use a partially extruded cartridge, unless using a new static mixer in which there is no cross-contamination.

• Use expired material or material that has cured.

• Continue use if you notice any abnormal noise or vibration when operating.

• Continue use if you are on unstable footing, have lost your grip, or have fallen.

Check the plant air supply pressure. For
optimum performance the supply pressure
must be greater than 7bar (100psi) and less

Note: The dispense gun will work at lower
supply pressures, but ow rates could be
reduced and may vary.

Important: Before increasing the uid
pressure, verify that both material
components are travelling equally through the
mixer. As needed, dispense unmixed material
into a waste container.

Note: Perform this process for each new or
partially used cartridge.

Pull the trigger to dispense material.

Note: This builds up a cushion of compressed
air inside the gun, which starts the ow
of material. When you release the trigger,
material ow ceases as the compressed air
escapes rapidly through a quick exhaust valve
at the rear of the gun.
