Thinning Materials; Run-Out Table And Thinning Chart - Homeright C800766 Instruction Manual

THINNING MATERIALS

In order for your sprayer to operate properly it is important to make sure the stain or paint is
thin enough to be sprayed. Thinning should be followed per the stain or paint manufacturer's
guidelines. Because materials differ from brand to brand, this guide can offer only general
information. The final guide to correctly thinned stain or paint is achieving the proper
spray pattern as shown in Figure A. Always follow the coverage rate recommended by the
manufacturer regardless of the thinning required. Because there is a variance in viscosity
between paint and stain brands, it might be necessary to thin five to 15 percent to achieve
optimum spray pattern.
Use the viscosity cup (included) and the chart below to determine whether you'll need to thin
the material you're using:
1. Dip the viscosity cup fully into the liquid you intend to spray.
2. Lift the viscosity cup out of the liquid, and, holding the cup over the paint or stain can,
time how long it takes for the liquid to drain out of the cup. This is known as the liquid's
run-out time. If it takes longer than the time shown on the chart for the liquid to leave
the viscosity cup, thin the liquid until the run-out time falls within the time bracket shown
for the liquid you're using.
3. When you've completed this process, clean the viscosity cup with warm, soapy water if
you're using a water-based product or per the manufacturer's instructions if you're using
an oil-based product.
NOTES:
• B e sure pick-up tube is inserted tightly into the intake port.
• T hin material according to the procedure outlined above.
• B efore each use, check the Brass Fluid Nozzle and Brass Fluid Needle for dried paint.
Keep Brass Fluid Needle clean.
• A lways thoroughly clean the sprayer after each use.
(See CLEAN UP AND MAINTENANCE, page 9.)
• T urn control knob counterclockwise for less flow — see Page 6 Step 7 for more detail.
• S train old paint or stain before using.
• S lowly stir paint or stain. To prevent air bubbles, do not shake stain or paint.
