OPERATION

BATTERY PROTECTION FEATURES
This product will accept RYOBI One+ 18 V lithium-ion battery packs and RYOBI One+ 18 V nickel-cadmium battery packs. RYOBI 18 V lithium-ion batteries are designed with features that protect the lithium-ion cells and maximize battery life. Under some operating conditions, these built-in features may cause the battery and the tool it is powering to act differently from nickel-cadmium batteries. During some applications, the battery electronics may signal the battery to shut down, and cause the tool to stop running. To reset the battery and tool, release the trigger and resume normal operation. NOTE: To prevent further shut down of the battery, avoid forcing the tool. If releasing the trigger does not reset the battery and tool, the battery pack is depleted. If depleted, the battery pack will begin charging when placed on the lithium-ion charger.

To install:
Place the battery pack in the tool. Align the raised rib on the battery pack with a groove in the battery port. Make sure the latches on each side of the battery pack snap in place and that the battery pack is secured in the tool before beginning operation.
To remove:
Depress the latches on both sides of the battery pack to release the battery pack and remove it from the tool

SELECTING PAINT
This is a highly versatile Spray System that can be used with several different spray mediums including varnishes, wood preservatives, enamels, as well as oil-based and water-based paints. The viscosity of these mediums is less than 135 DIN SEC. However, some materials cannot be sprayed so please check the recommendation ofthe manufacturer before buying the paint. If a material refers to brush application only then it usually cannot be sprayed.
THIS UNIT CAN NOT BE USED FOR TEXTURED PAINTS. USE OF THESE MATERIALS WILL CAUSE PREMATURE WEAR, WHICH WILL VOID THE GUARANTEE. TO OBTAIN THE BEST RESULTS FROM YOUR SPRAY SYSTEM PLEASE READ THE INSTRUCTIONS CAREFULLY BEFORE USE.

PREPARING FOR OPERATION
Preparation of the surface and thinning of the paint are the two most important methods to be concerned with to obtain the best results from your Spray System.
Preparing the Spray Surface
Ensure all surfaces are free from dust, dirt, rust and grease. If necessary rub down with sandpaper, or similar. Masking of areas is important to ensure you do not spray those areas you wish to remain untouched.

THINNING OR DILUTING SPRAY MATERIAL
Your Spray System is supplied with a viscosity cup. Viscosity is a technical term used to indicate if a product is very thin or very thick. If thin, the viscosity is said to be low, while if very thick the viscosity is said to be high. Thinning is very important when spraying. Most paints are supplied ready for brush application and may need to be thinned (diluted) for spraying purposes. Follow the manufacturers guide for thinning in conjunction with a Sprayer. If in doubt please contact the manufacturers of the paint. The viscosity cup supplied will help you determine the correct thickness of the paint. Paint is “thinned” by adding the substance which the paint is based upon. If a water based paint then water is added. If oil based then white spirit.

IDEAL VISCOSITY

This Sprayer can be used with solutions that take between 12 – 18 seconds to empty through the viscosity cup. Dip the viscosity cup into the paint and fill up. Time is how long it takes for the viscosity cup to empty. see figure 10. Using the above chart (or manufacturer’s instructions) as a guide, determine if the material requires further thinning,if so then thin accordingly. If the paint requires thinning, start with a 10% dilution of the paint. For example:

To do this, fill a 1-liter container with the required paint. Then use the viscosity cup supplied to add 100 ml of the required thinner. Stir the contents thoroughly, and measure the viscosity using the viscosity chart above. If paint requires further thinning then repeat the above step.
NOTE: Some paints are outside the ranges listed above. Please contact our helpline for further information.

FILLING SPRAYER WITH PAINT/STAIN

See Figures 3-4.
Remove and discard any skin that has formed on top of the paint or stain, then thoroughly mix the material in its original container before beginning.
NOTE: Older containers of stain and paint may need to be strained before use.

1.  Remove the battery pack from the sprayer.
2.  Remove the quick-lock container by twisting clockwise so that the arrow on the container lines up with the “unlock” symbol on the lid.
3.  Fill the container with paint or stain as desired. Do not fill above the max fill mark on the container.
4.  Reinstall the container on the sprayer and twist counterclockwise so that the arrow on the container lines up with the “lock” symbol on the lid.

To switch tips:

• Remove the battery pack from the sprayer.
• Remove the installed tip by turning it counterclockwise.
• Install the desired tip and rotate clockwise to tighten securely.
  NOTE: The tip should be tightened securely by
  hand. A too loose or overtightened tip may cause the
  sprayer to leak or be damaged.\

Rotate the adjusting arm 1/4 turn in the direction
needed to switch the direction of the tip spray.
While holding the adjusting arm in position, rotate the
fan tip clockwise until securely tightened.

OPERATING THE SPRAYER
See Figure 6-9.
Place a line of lubricant on the piston. To gain access to the piston, follow the instructions in Cleaning the Sprayer for Storage in the Maintenance section ofthis manual. Ensure surface to be painted is free of dust, dirt, andgrease. Mask or cover any areas not intended to be painted or stained. Be aware of wind that may cause your paint or stain to spray into areas not desired. Always use drop cloths or other cover to protect areas thatare not intended to be painted or stained. Fill the quick-lock container with no more than 1 liter of desired paint or stain.
NOTE: After every 4 refills of the quick-lock container, add a line of lubricant to the piston. See Cleaning the Sprayer for Storage for instructionson disassembling the sprayer to gain access to the piston. Select the proper spray tip for desired spray pattern.Install the battery pack in the sprayer. Pull the switch trigger to spray paint. Release the switch trigger to stop paint spray. Practice spraying on a piece of scrap material to test your spray pattern and to prime the pump before beginning. If you cannot get a good spray pattern withan even amount of paint or stain throughout, refer to either the Dilution section or Troubleshooting section later in this manual.
NOTE: The pump must be primed after every paint change and at first use after storing. Spray paint at a scrap surface for at least 20 seconds to prime.To create an even coating over the entire surface:

•  Move your arm at a steady rate of speed and make sure to move your entire arm, not just your wrist.
•  Keep the sprayer an even distance from the area being sprayed, which should be between 20 to 25 cm from the tip of the sprayer to the surface being sprayed.
•  Depress the trigger to begin the spray off the material you want to paint. Operate the sprayer instraight horizontal or vertical strokes across the surface being painted, then release the trigger off the material to end the stroke.
  NOTE: For spray quality consistency when using thinner paints, it may be necessary to keep the trigger depressed between strokes.When finished, remove the battery pack, return any unused paint or stain to its original container, and thoroughly clean the sprayer.
