MAINTENANCE

CAUTION

Thorough flushing and proper maintenance are es- sential 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 immedi- ately after each use.

ALWAYS fully extend the telescoping extension when flushing to clean it thoroughly.

ALWAYS drain all water out of the roller valve and extension and leave the system filled with mineral spirits to prevent corrosion.

Flushing (Latex Paint Only)

1.Turn the ON/OFF switch to OFF.

2.Fully extend the telescoping extension.

3.Trigger the roller valve and roll out the excess paint onto a wall or newspaper. Remove the roller cover and diffuser, and soak in a pail of warm soapy water.

4.Place the suction tube in the pail of warm, soapy wa- ter. 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. Release the trigger and shut off the pump as soon as all paint is drained, to avoid contaminating the paint with the flushing water.

5.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 it is cold). Pump the extension in and out a few times to clean it, and then leave it extended. Open the priming valve for a few seconds to clean the prim- ing tube. Close the valve.

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

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

8.Using clean, clear water, flush again, changing water as often as necessary, until the system is thoroughly cleaned.

9.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. Retract the extension before storing it.

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 mineral spirits.

10.Clean the roller cover thoroughly by rinsing it inside and out. Clean the diffuser as explained on page 3.

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