???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 ???t 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 ori???ce. 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 ???rst, and then remove the spray tip/nozzle to clean it.

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

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 ???rmly 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.
