ADJUSTABLE EXTENSION ROLLER KIT 218±625

Installation

1.Assemble the roller kit as shown in Fig 2. Be sure the gasket is in place between the gun and adapter.

2.Extend the tube to the desired length and tighten the locknut securely.

NOTE: Always allow cold equipment to warm to room temperature before using.

Operation

1.Be sure the fluid drain valve is closed and the gun safety latch is engaged. Then start the pump and set it to the lowest possible operating pressure.

2.Disengage the gun safety latch and trigger the gun briefly until paint comes to the roller.

3.Experiment with triggering and rolling the paint until you determine just how often you need to trigger the gun to keep an even flow of paint to the roller.

4.Increase the pump pressure only if you cannot get a sufficient supply of paint to the roller.

5.To adjust the extension tube while paint- ing, engage the gun safety latch. Loosen the locknut and extend or retract the tube. If retracting, some paint in the tube will be pushed out to the roller. Either roll this excess paint onto the wall, or completely retract the tube, drain the excess paint into a pail, then adjust the tube length. Tighten the locknut securely.

6.Whenever you stop painting, follow the PRESSURE RELIEF PROCEDURE on page 3. Then elevate the roller end of the tube to prevent paint from draining.

7.Flush the pump, gun and extension tube immediately after each use to prevent paint from drying in the equipment and damaging it. See Flushing, below.

NOTE: A Flush Kit, Part No. 218±944, can be used to flush water±base paint from the Extension Tube and Roller Frame. Instructions are on the kit package.
