PRACTICE FIRST
Practice spraying water on newspaper or cardboard. This will give you the feel of the
sprayer and all of its features. Follow the instructions for adjusting to the proper spray
pattern.
1. Check the following: (See Figure A.)
• Spray tip is screwed on tightly.
• Remove container from cylinder housing.
• Pick-up tube inserted tightly into the longer port of the cylinder housing.
2. Fill container with water. Refasten container to cylinder housing.
3. Plug in the sprayer.
4. Press switch. Allow a few seconds for the unit to spray water.
5. As you spray, adjust the volume control knob and notice the difference in spray volume
and spray pattern. Adjust the volume control knob until you get the best possible spray
pattern.
NOTE
: The best distance for spraying is 10 in. to 12 in. Too far away may cause
excessive overspraying and too close may cause excessive spray build-up (runs). See
Figure B.
6. Keep a stiff wrist. Do not arch your wrist at the beginning or the end of the stroke. Do
not stop the motion of the unit while spraying. The path of the sprayer must pass
beyond the area being sprayed, and the switch must be triggered on and off as the
sprayer passes into and out of the spraying area. See Figure C.
NOTE
: Stopping the motion of the sprayer or swinging into a new stroke pattern while
spray is being delivered will result in heavy spray build-up at the edges of the stroke.
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 D. 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.
NOTES
:
• Use the correct spray tip for the material being used. (See spray tip selection chart
below.)
• Be sure pick-up tube is tightly inserted in correct intake port.
• Thin material to proper viscosity, per manufacturer’s requirements.
• Before each use, check spray tip and atomizer valve for wear.
• Always thoroughly clean and oil the sprayer after each use.
• If you hear a low humming sound, immediately stop pressing the trigger.
See
TROUBLESHOOTING.
• Thin material may spray better at low power setting.
• Old stain or paint should be strained before using.
• Stir stain or paint slowly. To prevent air bubbles, do not shake stain or paint.
