Figure 11 - Spraying Technique

  A)  The key to a good paint job is an even coating over the entire 

surface.  Keep your arm moving at a constant speed and keep 

the spray gun at a constant distance from the surface.  The 

best spraying distance is 25 to 30 cm between the spray tip 

and the surface.  

  B)  Keep the spray gun at right angles to the surface.  This means 

moving your entire arm back and forth rather than just flexing 

your wrist.

  C)  Keep the spray gun perpendicular to the surface, otherwise 

one end of the pattern will be thicker than the other.

  D)  Trigger gun after starting the stroke.  Release the trigger 

before ending the stroke.  The spray gun should be moving 

when the trigger is pulled and released.  Overlap each stroke 

by about 30%.  This will ensure an even coating.

i

When finished spraying, perform Pressure Relief 

Procedure.

i

If you expect to be away from your spray project for 

more than 1 hour, follow the Short Term Cleanup 

procedure described in the Cleanup section of this 

manual.

Figure 12 - Practice

  1.  Be sure that the paint hose is free of kinks and clear of objects 

with sharp cutting edges.

  2.  Slide the PressureTrac™ to its to its lowest setting.
  3.  Turn the PRIME/SPRAY valve to SPRAY.
  4.  Slide the PressureTrac™ to its highest setting.  The paint hose 

should stiffen as material begins to flow through it.

  5.  Unlock the spray gun.
  6.  Trigger the spray gun to bleed air out of the hose.
  7.  When material reaches the spray tip, spray a test area to check 

the spray pattern.

  8.  Use the lowest pressure setting necessary to get a good spray 

pattern (A).  If the pressure is set too high, the spray pattern 

will be too light.  If the pressure is set too low, tailing will 

appear or the paint will spatter out in blobs rather than in a 

fine spray (B).

Figure 13  - Unclogging the Spray Tip

i

If the spray pattern becomes distorted or stops 

completely while the gun is triggered, follow these 

steps.

Danger

Do not attempt to unclog or clean the tip with your 

finger.  High pressure fluid can cause injection 

injury.

  1.  Release the trigger and lock the gun off.  Rotate the reversible 

tip arrow 180º so that the point of the arrow is toward the rear 

of the gun (see figure 13).

i

Under pressure, the spray tip may be very difficult to 

turn.  Turn the PRIME/SPRAY knob to PRIME and 

trigger the gun.  This will relieve pressure and the tip 

will turn more easily.

  2.  Turn the prime/spray knob to spray. 
   3.  Unlock the gun and squeeze the trigger, pointing the gun at 

a scrap piece of wood or cardboard.  This allows pressure in 

the spray hose to blow out the obstruction.  When the nozzle 

is clean, material will come out in a straight, high pressure 

stream.

  4.  Release the trigger and lock the gun off.  Reverse the tip so 

the arrow points forward again.  Unlock the gun and resume 

spraying.

Cleanup

i

If you used latex spray materials, use warm, soapy 

water to clean the sprayer.  If you used oil-based spray 

materials, use mineral spirits.

i

Do not use mineral spirits or paint thinner on latex 

materials, or the mixture will turn into a jelly-like 

substance which is difficult to remove.

Figure 14 - Short Term Cleanup

i

Follow these steps when using latex materials only.  If 

using materials that are oil-based, follow the Cleanup 

and Long-Term Storage steps.

A) Shutdown

  1.  Perform the Pressure Relief Procedure (see figure 6) and 

unplug the sprayer.

  2.  Pour 1/2 cup water slowly on the top of the paint to prevent 

the paint from drying.  

  3.  Wrap the spray gun assembly in a damp cloth and place it in 

a plastic bag.  Seal the bag shut.  Place the sprayer in a safe 

place out of the sun for short-term storage.

B) Startup

  1.  Remove the gun from the plastic bag.  Stir the water into the 

paint.

  2.  Turn the PRIME/SPRAY knob to PRIME.  
  3.  Plug sprayer in.  
  4.  Turn the switch to ON (I).
  5.  Turn the PRIME/SPRAY knob to SPRAY.   Test the sprayer on a 

practice piece and begin spraying.

Figure 15 - Flushing the System

   1.  Lock the gun and remove spray tip assembly.  Submerge 

suction set into a bucket with appropriate cleaning solution 

(a).

  2.  Place a waste container (b) next to the original material 

container (c).  The containers should be touching.  Aim the 

spray gun into the side of the original material container (c) 

and hold the trigger.

  3.  While pulling the gun trigger, turn the pump ON (l), and turn 

the PRIME/ SPRAY knob to SPRAY to purge material from the 

hose back into the original container.  Keep holding trigger 

through next steps.  

  4.  When cleaning solution flows from the spray gun, keep 

holding the trigger and aim the spray gun into the side of the 

waste container (ground gun with a metal container if flushing 

with flammable solvent).  

  5.  Trigger the gun until the fluid flowing out of the gun is clear.  

You may need to dispose and obtain new cleaning solution. 

  6.  Turn the PRIME/SPRAY knob to PRIME and trigger gun to 

relieve pressure.
