Flushing
To help prevent fire and explosion:
• Flush equipment only in a well-ventilated area.
• Do not spray flammable fluids.
• Do not turn on heaters while flushing with
flammable solvents.
• Flush out old fluid with new fluid, or flush out old
fluid with a compatible solvent before introducing
new fluid.
• Use the lowest possible pressure when flushing.
• All wetted parts are compatible with common
solvents. Use only moisture-free solvents.

To flush entire system, circulate through gun fluid

To prevent moisture from reacting with
isocyanate, always leave the system filled
with a moisture-free plasticizer or oil. Do not
