If none, lift lever slightly to release your finger.• Verify that both pump assemblies and hose assemblies do not leak under pressure using the steps above.• Pull the lever down completely.• Remove the full container and replace it with an empty container.• Pump the unit until both pumps are empty.• Shake suction the hoses to drain as much fluid as possible.• Leave the hoses hanging to air dry.• Wipe the unit off using paper towels.• Screw the wetting cup in place.• Place new product on the MPU02 and prime the pumps. (Refer to the user manual for priming instructions)• Dispense enough fluid to ensure the reducer has been flushed from MPU02 unit entirely.• Dedoes suggests a spray panel test to verify clear coat finish quality.MPU Maintenance and Repair Guide |
