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. See Figure A and:
• Be sure the spray tip is screwed on tightly.
• Remove container from cylinder housing.
• Be sure the pick-up tube inserted tightly into the forward-most 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. Start with the Volume Control Knob turned fully counterclockwise. As you spray,
turn the knob clockwise 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 overspray and an inconsistent, thin coat. Too close may cause excessive
spray build-up (runs). See Figure B.
6. Keep the gun level and totally perpendicular to the wall, making sure to start your stroke
before pulling the trigger and then releasing before the end of your stroke. See Figure C.
As you move from one stroke path to another, keep the gun moving when changing
direction. Be sure to overlap your spray pattern from one direction to the other to
avoid a light, patchy coverage.
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.
In the event of runs or excessive build up, use a paint roller to "back roll" the area,
evening out any inconsistent coverage.
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 guidelines of the stain
or paint manufacture. 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.
• 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.
