Installation
! WARNING
INJECTION HAZARD
To reduce the risk of a serious injury,
always follow the Pressure Relief Procedure
on page 3 whenever you are
instructed to relieve the pressure.
FIRE AND EXPLOSION HAZARD
To reduce the risk of static sparking, which can cause a
fire or explosion and result in serious injury, including
electric
shock, and property damage, always follow these
Precautions.
_ Read and follow the warnings in FIRE and EXPLOSION
HAZARD on page 2.
_ Provide electrical grounding continuity throughout
the entire spray system as instructed below.
_ Have a trained and qualified person perform all
electrical wiring.
_ Comply with all applicable local, state and
national fire, electrical and other safety
regulations.
INJECTION HAZARD
Your spray system must have a bleed type
master air valve and a fluid drain
valve. These two accessories help reduce
the risk of serious injury, including fluid injection,
splashing in the eyes or on the skin, or injury
from moving parts, if you are adjusting or repairing
the pump or gun.
1. Connect a grounded fluid hose to the gun fluid inlet.
2. Without the spray tip installed, start the pump or sprayer and flush and prime it according to the pump or sprayer instructions.
3. Relieve the pressure.
4. With the gun safety Trigger lock, unscrew the tip guard (1) and install the tip (2) and filter assembly (3) in the tip guard nut. Screw the
assembly firmly onto the gun. Tighten with a wrench. See Fig. 1.
5. Strain the fluid you are spraying if it contains particles which clog the spray tip.
FIG1.
Required Accessories
1. The bleed-type master air valve relieves air trapped between this valve and the pump after the air regulator is shut off. Trapped air can
cause the pump to cycle unexpectedly.
2. The fluid drain valve assists in relieving fluid pressure in the displacement pump, hose and gun; triggering the gun to relieve pressure may
not be sufficient.
Electrical Grounding
1. Provide electrical grounding for the pump or sprayer as instructed in its separate manual.
2. Provide electrical grounding for the air compressor or hydraulic power supply according to the local code and the manufacturer’s
recommendations.
3. Use only electrically conductive fluid hoses with a maximum of 500 feet (150 m) combined hose length to ensure grounding continuity.
4. Obtain electrical grounding continuity for the spray gun by connecting it to a properly grounding fluid hose and pump or sprayer.
5. Provide electrical grounding for these components according to the local code: the fluid supply container, the object being sprayed, and
all of the solvent pails used when flushing. Use only metal pails, which are conductive. Do not place the pail on a non-conductive surface,
such as paper or cardboard, which interrupts the grounding continuity.
6. To maintain grounding continuity when flushing or relieving pressure, always hold a metal part of the gun firmly to the side of a
grounded metal pail, then trigger the gun.
Operation
Pressure Relief Procedure
- To reduce the risk of serious bodily injury, including fluid injection, splashing fluid or solvent in the eyes or on the skin, or injury from moving
parts or electric shock, always follow this procedure whenever you shut off the sprayer, when checking or servicing any part of the spray
system, when installing, cleaning or changing spray tips, and whenever you stop spraying.
1. Lock the gun trigger safety.
2. Shut off the power supply to the pump and close any bleed-type master air valves.
3. Unlock the gun trigger safety. Hold a metal part of the gun firmly to the side of a grounded metal pall, and trigger the gun to relieve pressure.
4. Lock the gun trigger safety.
5. Open the pressure drain valve(required in system), having a container ready to catch the drainage.
6. Leave the drain valve open until you are ready to spray again.
If you suspect that the spray tip or hose is completely clogged or that pressure has not been fully relieved after following the steps above,
VERY SLOWLY loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually, then loosen completely. Now clear the
tip or hose .

Startup
1. Start the pump. Adjust the fluid pressure so the spray is completely atomized. Always use the lowest pressure necessary to get the desired
results. Higher pressure may not improve the spray pattern and will cause premature tip and pump wear.
2. If adjusting the pressure does not give a good spray pattern, try another size tip. Relieve the pressure before changing a spray tip.
3. Use a full-open, full-close trigger action. Hold the gun about 14 inches (350 mm) from and at right angles to the work surface. Don’t swing
the gun in an arc. Practice to find the best length and speed of stroke.
How to Adjust the Spray Pattern
1. Relieve the pressure.
2. Loosen the tip guard retaining nut.
3. Turn the spray tip so the groove is horizontal for a horizontal spray pattern and vertical for a vertical pattern. See Fig. 1.
4. The spray tip orifice size and spray angle determines the coverage and size of the pattern. When more coverage is needed, use a larger
spray tip rather than increasing the fluid pressure.
! WARNING
INJECTION HAZARD
To reduce the risk of an injection or splashing fluid in the
eyes or on skin, follow these precautions before removing,
cleaning or changing a spray tip or tip guard.
_ Do not hold your hand, body, or rag in front of the spray
tip when cleaning or checking a clogged tip.
_ Always point the gun toward the ground or into a waste
container when checking to see if the spray tip is
cleared.
_ Do not try to “blow back” paint; this is NOT an air spray
gun.
_ Follow the Pressure Relief Procedure on page 3 before
wiping the fluid buildup off the gun or spray tip, before
removing the tip guard or the spray tip, and whenever
you are instructed to relieve the pressure.
FIRE AND EXPLOSION HAZARD
To reduce the risk of a serious injury from fluid injection,
static sparking, or splashing fluid in the eyes on or the
skin, follow these precautions when flushing.
_ Be sure the entire system and the flushing pails are
properly grounded. Refer to Electrical Grounding on
page 3.
_ Remove the spray tip from the gun.
_ Use the lowest possible fluid pressure.
_ Maintain firm metal-to-metal contact between the gun
and pail during flushing.
_ Follow the Pressure Relief Procedure on page 4
whenever you are instructed to relieve pressure.
How to Clear or Clean a Clogged Spray Tip.
NOTE: Clean the tip frequently during the daily operation and at the end of the work day. This helps keep fluid buildup from drying and
clogging the spray tip.
1. Relieve the pressure.
2. Use a solvent–soaked brush to clean the tip.
3. Remove the tip (25) and the filter (26). See Fig. 1.
4. Blow out the tip obstruction with air from the front of the spray tip, or soak the spray tip and gun nozzle long enough to dissolve the
obstruction. If the clog won’t dissolve, tap the back of the spray tip against a flat surface to remove it.
How to Flush the Gun.
Always flush the pump and the gun before the fluid being sprayed can dry in it.
NOTE: If it is available, the flushing procedure provided in your pump or sprayer manual should be
used instead of this procedure.
1. Follow the Pressure Relief Procedure, page 3. Remove the tip guard and spray tip. Soak and clean the parts.
2. Put the pump intake in a grounded pail of water of solvent. Start the pump at its lowest pressure.
3. Trigger the gun into the original pail. When solvent appears, release the trigger.
4. Now trigger the gun into the solvent pail. Circulate the fluid until the system is thoroughly flushed.
5. Follow the Pressure Relief Procedure, page 2.
