MAINTENANCE

CAUTION

Thorough flushing and proper maintenance are essential to keep your system working properly.

Improper flushing or maintenance may prevent the system from working the next time you need it, and may result in costly damage to the system.

Always flush your system thoroughly and immediate- ly after each use.

Always drain all water out of the roller valve and ex- tension and leave the system filled with mineral spir- its to prevent corrosion.

NOTE: A Garden Hose Flush Adapter, P/N 220–231, is included. This adapter is placed at the pump inlet and uses a standard city water supply to aid in flushing. Instructions on how to use it are in- cluded with the adapter.

Flushing Procedure (Latex Paint Only)

1.Turn the ON/OFF switch to OFF.

2.Trigger the roller valve and roll out the excess paint from the roller onto a wall or newspaper. Remove the roller cover and dif fuser, and soak these parts in a pail of warm, soapy water.

3.Put the suction tube in a pail of warm, soapy water. Hold the roller frame over the paint pail, turn on the system, and trigger the roller valve to drain and save the paint in the hoses. See Fig 3. Release the trigger and shut of f the pump as soon as all the paint is drained. This avoids contaminating the paint with the flushing water.

4.Now hold the roller frame over the flushing pail. Turn on the pump and trigger the roller valve. Circulate the solution for three to five minutes (five to ten minutes if using a cold solution). Open the priming valve for a few seconds to clean the priming tube. Close the priming valve.

5.Raise the suction hose above the water and run the pump for a few seconds to drain the flushing solution. Shut off the pump.

6.Wash off all external parts of the hoses, extension, roller frame, roller valve and pump.

7.Flush again with clean, clear water. Change the wa- ter as necessary , until the system is thoroughly cleaned.

8.Finally, flush the system with clean mineral spirits for just a few seconds. Open the priming valve and turn off the pump. Some mineral spirits must be left in the system to prevent corrosion.

CAUTION

Never leave water or water-based paint (latex) in the system. To prevent corrosion in the pump, exten- sion, roller valve and roller frame, your final flush must be with mineral spirits.

9.Thoroughly rinse the roller cover inside and out. Clean the diffuser as explained on page 9.

10.Oil the needle in the roller valve and trigger the valve a few times to distribute the oil. See Detail A, Fig 3.
