OperationOperationPail Change-OverExcessive Ram air pressure in the material pail couldcause the pail to rupture, causing serious injury.Ensure that the pressure settings are set to the recommendedair pressure. Refer to Pressure Settings,page 8.1. If the machine is equipped with the color option,refer to Fill the Colorant Tank and Prime theColor Injector (Optional), page 26.2. Calibrate the string pots if required. Refer to StringPot Calibration, page 40.3. Turn the Ram Control Valve to the DOWN positionand let the air escape from the Ram Air Cylinders ifa pail is installed.5. Lower the Pail Shelf to its minimum height.6. Clean the bottom of the platen with a flat, non-metalscraper.7. Load the new pail into the machine, paying specialattention to put the “A” material on the “A” side.NOTICEFailure to separate chemical components will result inthe curing of material in the pumps and hoses.NOTICETo avoid cavitation and component interference, installthe pail on the pail shelf so that the handle of the pailwill not interfere with the ram during normal machineoperation.8. Apply a small amount of lubricant to the platen sealto aid the installation. Use a small amount of materialif a lubricant is not available.9. Open the Bleed Ball Valve on the platen hub.Activating the blow-off button prior to reaching 30 psi(210 kPa, 2.1 bar) of Ram air pressure may result inserious injury. Activate the blow-off button only whenthe pressure reaches 30 psi (210 kPa, 2.1 bar) orbelow.4. Press the blow-off button to push the pail and shelfoff the platen.34 332312A
Operation10. Set the Ram Air Regulator to 5 psi (35 kPa, 0.3 bar).11. Turn the Ram Control Valve to the UP position toraise the Pail Shelf to the platen.12. Slowly increase the Ram Air Regulator to the operatingpressure.NOTE: If your pails have liners, use special care not topush them down into the pail with the platen.NOTICETo avoid cavitation and machine damage, the RamControl Valve should be left in the UP position whilepumping.NOTE: Once the platen enters the pail, air and materialwill exhaust out the ball valve on the platen hub. Allowthe silicone to flow until it is free of bubbles then closethe ball valve.13. Repeat the Pail Change-Over procedure to loadthe material pail for the other side.332312A 35
