♦ Manual Sealant Guns

♦ Pressure Relief Procedure

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.

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..

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.

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.

Gun Tip/Nozzle Safety

Use extreme caution when cleaning or changing 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.

309968D

Pressure Relief Procedure

This procedure describes how to relieve pressure for the sealant gun. To reduce the risk of serious injury, use this procedure whenever you shut off the sealant gun and before checking or adjusting any part of the sealant gun.

1. Shut off air supply to pump. Close any bleed-type master air valves.

2. Hold metal part of gun firmly to side of a grounded metal pail. Trigger gun to relieve pressure.

3. Open drain valve (required in your system) having a container ready to catch drainage.

4. Leave drain valve open until you are ready to dispense sealant again.

Note

If you suspect that the nozzle or hose is completely clogged, or that pressure has not been relieved fully after following the above steps, very slowly loosen the retaining nut or hose end coupling to relieve pressure gradually. Then loosen completely. Now clear the tip/nozzle or hose.

309968D 5

Troubleshooting

Problem
