WAGNER Project Pro 119 - 0418C

i

The spray tip should not be attached to your spray gun 

when purging your spray hose.

  2.  PULL the trigger and aim the spray gun at the side wall of a 

waste container.  If using oil-based materials, the spray gun 

must be grounded while purging (see warning below).    

Danger

Keep hands clear from fluid stream.  Ground the gun 

by holding it against the edge of a metal container 

while flushing.  Failure to do so may lead to a static 

electric discharge which may cause a fire.

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

the PRIME/SPRAY knob to Spray.  Hold the trigger until all air, 

water, or solvent is purged from the spray hose and material is 

flowing freely. 

Danger

If the PRIME/SPRAY knob is still on SPRAY, there will 

be high pressure in the hose and spray gun until the 

PRIME/SPRAY knob is turned to PRIME.

  4.  Release trigger.  Turn the prime/spray knob to PRIME.  Turn 

the pump OFF (O).  Trigger the gun into the waste container to 

be sure that no pressure is left in the hose.

Figure 10 - Attaching the Spray Tip

Danger

POSSIBLE INJECTION HAZARD.  Do not spray 

without the tip guard in place.  Never trigger the 

gun unless the tip is in either the spray or the unclog 

position.  Always engage the gun trigger lock before 

removing, replacing or cleaning tip.

  1.  Lock the spray gun off.

  2.  Thread the tip guard onto the gun.

i

When attaching the tip guard to the gun, align the tip 

guard as shown in figure 10 (a), then tighten by hand 

(b).

Spraying

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 are using water-soluble materials, use warm suds 

to clean the spray device. If you are using solvent-

based spray, use a suitable solvent for cleaning, with a 

flash point of over 21°C.

i

Do not use solvents for water-soluble materials, as the 

mixture will turn into a gel-type substance which is 

difficult to remove.

Figure 14 - Short Term Cleanup

i

Only follow these instructions when using water-

soluble materials.  If you are using solvent-based spray, 

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.
