Flushing the Gun
The entire hot melt application system, including the gun, must be flushed
after installing a new gun. Flushing removes excess dirt and charred
material from the applicator system and purges any Type R fluid left over in
the gun from factory testing.
CAUTION: Hot! Risk of burns. Hot applicator parts, splashed hot melt
material, and hot gun surfaces can cause severe burns. Wear long‐sleeved,
heat‐protective clothing, safety goggles, and heat‐protective gloves.
WARNING: Risk of burns. System or material pressurized. Airtrapped in
the hose or gun can spit out molten adhesive that can cause severe burns.
Failure to relieve hydraulic pressure can result in serious burns. Relieve
pressure.
Flushing all Modules Except Reduced Cavity
1. Relieve hydraulic pressure (refer to the Relieving Hydraulic Pressure
procedure earlier in this section).
2. Ensure that the trigger safety is in the LOCKED position.
3. Wear safety gloves.
