Warnings WARNING FIRE AND EXPLOSION HAZARD Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help pre- vent fire and explosion: • Use equipment only in well ventilated area. • Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths (potential static arc).
Important Two-Component Material Information Important Two-Component Material Information Keep Components A (Red) and B (Blue) Separate Cross-contamination can result in cured material in fluid lines which could cause serious injury or dam- age equipment. To prevent cross-contamination of the equipment’s wetted parts, never interchange component A (Red) and component B (Blue) parts.

Operation System Calibration Procedure Balancing the pump pressure: The key to getting consistent ratios is to dispense at roughly the same pressure as the pumps are being fed from the feed system. The screen below shows all pres- sures. NOTICE NOTE: Pressures can only viewed if kit 24M127 is After the catalyst has been added, the material is installed.
