• Perform a pressure test after each repair or replacement of parts within the MPU02 before use to ensure there are no leaks.
• Turn both of the front pump valves to the "ON" position.
• Unscrew the wetting cup and set it aside.
• Visually check that both pump pistons go completely down within each pump and are adjusted correctly.
• Pour one quart of reducer in a container and place under front pump.
• Place both of the front pump suction hoses into the front container with the reducer.
• Pour one quart of reducer into a container and place under the rear pump.
• Place the rear pump suction hose into the rear container with the reducer.
• Pump the lever in quick short strokes making sure the lever is going completely down until both pumps are primed.
• Once the air is pumped out of the pumps, pump the lever one full stroke and verify that the pumps are working correctly.
• With the lever at the half stroke and reducer lling the pumps, block the end of one of the discharge tubes with your nger.
• Pull the lever down rmly and hold it down.
• Visually inspect the seals in each pump to be sure that uid does not by-pass the seals.
• Visually check all connections of the pump for any leakage. If none, lift lever slightly to release your nger.
• 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 uid as possible.
• Leave the hoses hanging to air dry.
• Wipe the unit o 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 uid to ensure the reducer has been ushed from MPU02 unit entirely.
• Dedoes suggests a spray panel test to verify clear coat nish quality.
