NOTICE
To prevent cross-contamination in the gun, do not
interchange A component (isocyanate) and B
component (resin) parts. Cross-contamination can
result in cured material in the gun. Cured material may
damage the sealing surfaces, block fluid passages,
and prevent gun function.
Damaged check o-rings (26f, 26g) may result in
external leakage. To avoid potential leakage and
serious injury from skin injection, replace any
damaged o-rings.
