4. Attach container to sprayer.

5. Plug sprayer into outlet.

6. Adjust spray pattern to horizontal, vertical, or cone. (See page 7.)

7. Set the flow to maximum by turning the volume control knob fully clockwise.

8. Spray surface, keeping sprayer level. Use a sweeping and overlapping motion

Cleaning Instructions

1. Unplug sprayer, remove container, and empty contents.

2. Fill sprayer with cleaning solution, plug in sprayer, and operate trigger until solution comes through nozzle. Do not submerge in liquid.

3. Remove parts. Clean and dry thoroughly according to Step Two of the Clean Up instructions. See page 8.

HOW TO USE

PRACTICE FIRST
Practice spraying water on newspaper or cardboard. This will give you the feel of the sprayer and familiarize you with its features. Follow the instructions for adjusting to the proper spray pattern.

1. Make sure the spray tip is screwed on tightly. Familiarize yourself with the spray cap: Turn its wings to adjust to a horizontal, vertical, or cone spray pattern. **(See Figure A.)

**

2.  Remove the container from the spray gun by turning it counterclockwise.

3. Firmly insert the pick-up tube. (See Figure B. ) Place the pick-up tube with its angle pointing forward if you’ll be spraying mostly in the downward direction, and place it facing backward if you’ll be spraying mostly in an upward direction. This tube placement can be adjusted/changed at any time during your project.

4. Fill the container with water and re-fasten it.

5. Plug in the sprayer.

6. Engage the trigger and wait a few seconds for the unit to start spraying the water.

7. Turn the volume control knob fully clockwise to get maximum flow. Then, turn it counterclockwise and notice how the spray pattern changes in width and intensity.
   Adjust this knob until you get a good spray pattern. ( See Figure C. )

NOTE: The best distance for spraying is 4 to 10 inches (see Figure D) from the surface you’re spraying. Too far away may result in overspray (and wasted liquid), and too close may cause liquid build-up (runs).

8. Keep a stiff wrist. Do not arch your wrist at the beginning or the end of the stroke.
   (See Figure E.)
   
   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 F.)

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.
SURFACE PREP
Thoroughly clean all objects and surfaces to be sprayed, before spraying material on them.
You may want to mask or cover areas not intended to be sprayed.
SMALL PROJECTS
This sprayer uses airflow to transfer liquid to the work piece. It is recommended that for small projects, the user first tests the sprayer without adding liquid to the cup. The airflow may cause small pieces to move or fall during operation. Use caution and good judgement before spraying liquid.

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 5 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 while 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:

   • Be sure pick-up tube is inserted tightly into the intake port.

   • Thin material according to the procedure outlined above.

   • Before each use, check the Brass Fluid Nozzle and Brass Fluid Needle for dried paint.
     Keep Brass Fluid Needle clean.

   • Always thoroughly clean the sprayer after each use.
     (See CLEAN UP AND MAINTENANCE, page 8.)

   • Turn control knob counterclockwise for less flow — see Page 5 Step 7 for more detail.

   • Strain old paint or stain before using.

   • Slowly stir paint or stain. To prevent air bubbles, do not shake stain or paint.

RUN-OUT TABLE AND THINNING CHART

ADJUSTING THE SPRAY PATTERN
By turning the wings of the tip, the Finish Max Fine Finish Sprayer sprays in one of three patterns: horizontal, vertical, or cone. (See Figure D.) DO NOT engage the trigger while turning the tip, and be sure not to spray toward you, as this could cause injury.
(See Figure C & D)

SPRAYING INSTRUCTIONS
Caution: Do not twist electrical cord. Make sure heavy objects are not placed on it.
Keep electrical cord away from heat and sharp objects. To avoid a tripping hazard,  make sure cord is not in a heavy traffic area. Do not use the cord if it is damaged.
Use appropriate breathing protection, eye protection, gloves and clothing.

1. Make sure the container is empty and dry.
2. Pour paint or stain into the container.
3. Be sure the pick-up tube is inserted tightly in the intake port and the tube’s angle is as you want it. **(Figure E.)

**

4. Affix the container to the sprayer by turning the container counterclockwise.
5. Refer back to “Practice First” on page 5 and do this process again, this time to adjust the flow rate not to the water you used to practice but to the material now in the container. If, after making adjustments, you still are not satisfied with the spray pattern, refer to TROUBLESHOOTING on page 9.
6. Hold the sprayer 4 to 10 inches from the surface to be painted. While the angled pick-up tube permits you to spray in an upward or downward direction, try to tilt the sprayer as little as possible. Do not tip more than 45 degrees.
7. Overlap each stroke by about 1/3 of the spray pattern.
   NOTE: If you stop spraying for 30 minutes or longer: Before continuing, retest the spray pattern by spraying on newspaper or cardboard. If you are unable to adjust the spray pattern properly, it is possible the stain or paint material has started to dry. If this happens, clean the sprayer. See CLEAN UP INSTRUCTIONS.
   NOTE: If the spray pattern still is not correct, you may need to thoroughly clean the spray tip and pick-up tube. To keep the unit spraying properly, you should expect to clean it after dispensing each five to nine gallons of paint or stain. After cleaning, reassemble the parts.
   Check the nozzle for dried paint or stain from time to time while spraying. If dried paint or stain is present, use a wet cloth to wipe nozzle.
   AIR BLOWING NOZZLE
   The air blowing nozzle is a breeze-dusting device, suitable for dusting computer heatsinks, keyboards, air conditioner filter meshes and all kinds of precision instruments. ( See Figure  F.) However it is NOT suitable for liquid spraying

CLEAN UP & MAINTENANCE

NOTE: For easier and faster cleaning, consider purchasing the Rapid Clean Kit (C900042.M)
STEP ONE: CLEAN UP INSTRUCTIONS
NOTE: Proper clean up is essential to keep your sprayer in optimum working condition.
Dried by-products act like glue and will cause moving parts to stick. Failure to properly clean your paint sprayer will damage the unit. Taking the time to clean your sprayer immediately after use will help your sprayer last longer and work correctly. If you are finished with the project or are not going to use the sprayer within the day, you must follow these instructions for proper clean up.
Never store the sprayer longer than 30 minutes without cleaning.

1. Unplug sprayer from electrical outlet and pull trigger on spray gun so material inside unit flows back into the container.

2. Empty any remaining (stain or paint) material from the container.

3. Fill container approximately 1/2 full with appropriate cleaning solution.
   For latex, use warm soapy water; for oil-based, use a cleaning solution recommended by the material manufacturer.

4. Plug sprayer into an electrical outlet.

5. Press the switch of the sprayer until the cleaning solution passes through the spray nozzle for several seconds. **(See Figure A.)

**

6. Remove container and properly discard the cleaning solution.

7. Unplug the sprayer from the electrical outlet.
   STEP TWO: CLEAN UP INSTRUCTIONS FOR THE SPRAY TIP
   Use the brush (included) to complete the following steps.

8. Unplug sprayer from electrical outlet and pull trigger on spray gun so material inside unit flows back into the container.

9. Unscrew the container and discard any remaining cleaning solution.

10. Remove the pick-up tube from the sprayer and clean it with warm, soapy water.* **(See Figure B.)
