Operation

Topics Covered in this Chapter

♦ Manual Applications ♦ Automatic Appliations ♦ Air Requirements

Note

Read this manual thoroughly before installing sealant gun.

Inspect sealant gun for shipping damage. If damaged, notify the carrier immediately.

Manual Applications

The palm and pistol grip sealant guns are used in hand-held applications.

1. Secure gun in a way that allows proper routing of air hose and ﬁtting.

2. Make sure gun does not impede movement of person.

3. Tighten hose connections before operating equipment. The air-powered sealant gun can be supplied air from any standard air pump.

Topics Covered in this Chapter

♦ Air-Powered Sealant Guns ♦ Manual Sealant Guns ♦ Pressure Relief Procedure

Air-Powered Sealant Guns

The 950 Series, air-powered sealant guns dispense adhesives or sealants from 2.5, 6 or 12 ounce polyethylene cartridges. Each size of these lightweight, all metal guns, is available in two styles: pistol grip and palm grip.

The guns feature an interchangeable gun body and actuator with a fast change cartridge knob included. The cartridge retainers are corrosion-resistant, will ﬁt all handles and are made of high strength steel to prevent cartridge splitting under pressure.

In operation, the dispense rate is controlled through air pressure, trigger position and nozzle oriﬁce. When the gun is actuated, air pressure forces the plunger down, inside the cartridge, forcing material out the nozzle. When the trigger is released, pressure is removed and dispensing stops.

4. Do not exceed maximum working pressure of sealant gun.

Automatic Appliations

The palm grip and pistol grip sealant guns are not designed for use in high production operations. Never mount or secure any hand-held gun to a ﬁxture or robot arm.

Air Requirements

For information describing the air pressure requirements, refer to the technical data supplied with the sealant gun..

Manual Sealant Guns

The manually-operated sealant fun for 2.5, 6 and 12 ounce cartridges uses a smooth plunger rod for easy operation. Simply releasing the trigger, releases the pressure; dispensing is easy to control and stops quickly.

GunTip/NozzleSafety

Useextremecautionwhencleaningorchanging dispense sealant gun tips/nozzles. Always follow the Pressure Relief Procedure ﬁrst, and then remove the spray tip/nozzle to clean it.

Never wipe off build-up around the tip/nozzle until pressure is relieved.
